Do you ever find yourself saying something like, “Gosh this year has gone fast” or “I don’t know where the year has gone” or “it only seems like yesterday when….”?

I am sure we all have. Well, at least the older ones amongst us.

I have a theory. I can’t believe it’s just my theory but I haven’t seen it anywhere else so I am claiming it as mine. I’m calling it the “The Shamus Theory of Time Relativity”.

Time is a fixed thing (well, not really but for the purposes of my theory let’s say it is). A second is a second wherever in the world you are, a minute is a minute, an hour is an hour and so on.

But although time itself is fixed and measurable our perception of time is not. For example, studies have been done on the effect of colours on people’s time perception, involving a lecture given in a green room and the same lecture given in a blue room. The people attending the lectures had their watches removed so had no idea of how much time elapsed.

The same lectures each ran for exactly 30 minutes. The students attending the lectures were surveyed on their perception of the time and all of the students in blue room felt the lecture was snappy, to the point and interesting and lasted only about 20 minutes. The green room people thought it dragged on and felt like it was a 40 minute lecture. So their perception of time was vastly different.

Everyone has experienced children and the “Are we there

yet?” or when they ask how long until the school holidays, you say it’s 2 weeks and they say, “That’s forever” or something similar.

A year is a fixed amount of time. 12 months, 52 weeks, 365 days, 8,760 hours, 525,600 minutes or 31.536 million seconds. So why to a 4-year old does a year seem like forever and yet to a 60 year old the year went by in a flash?

“The Shamus Theory of Time Relativity” recognises that to a 4-year old a year represents a huge percentage of the time they have been alive. 25% in fact, so it seems like “forever” to them.

To a 20-year old a year represents a 20th of the time they have been alive or only 5%. To a 60-year old it represents only a 60th of the time they have been alive. A mere 1.6%. As you can see as we get older the percentage of a year relative to the time we have been alive gets smaller and smaller.

Therefore our perception is that that fixed length of time is actually going faster than it used to.

There are of course many academic studies performed over the years - invariably by people under 40 - so I’m still

sticking with my theory. One of these more plausible

theories was proposed In 2005 by psychologists Marc Wittmann and Sandra Lenhoff, who conducted a study and confirmed that those over 40 felt time had passed more quickly than those under 40. Their reasoning as to why this happened was; “When it comes to how we perceive time, humans can estimate the length of an event from two very different perspectives: a prospective vantage, while an event is still occurring, or a retrospective one, after it has ended”

Our perception of time, according to Wittman and Lenhoff, was that it is memory based and when we are having fun we generate more memories and time appears to go faster.

When we are younger we have more new and fresh experiences and learn lots of new skills. When we are adults our lives become more mundane and routine and we experience less moments that are unfamiliar to us. So our earlier years are more overrepresented in our autobiographical memory and on reflection seem to have lasted longer. This explains the cliché, “Time flies when you are having fun”

Unlike the Shamus Theory of Time Relativity, the bonus of this theory is that we can theoretically alter our perception of time and slow the passing of time by keeping our brain active, learning new skills and ideas and exploring new places. Sounds like an excuse to go fishing and have holidays to me.

The Importance of Tank CleaningTank cleaning between sprays is always important but no more important that if you have been using sulfonylurea herbicides like Rainbow & Brown’s MSF600. Even though this is on the label it is worth reinforcing this.

The sulfonylurea herbicides, like MSF600, have an affinity for binding to plastic tank walls, filters and hoses and then if not cleaned properly can come away on the next use meaning you are getting what might be an undesirable herbicide in your next spray mix. This is particularly true with some emulsifiable concentrate herbicides or insecticides that might have toluene as an ingredient.

Clean your tank and spray gear carefully and in accordance with the label directions.

Barley Grass Problems?Anecdotally some people have had success spraying barley grass with glyphosate at

0.8L/ha (just 800ml/hectare) in very carefully and accurately calibrated sprayers.

This is definitely not on label and we are not recommending this but if you are at

your wits end and were to try it you should do a small area first and be fully aware

of the risks as you could unintentionally kill off your pasture.

Which Potassium to Use?Potassium is available in many forms at many different prices. A Lucerne farmer might need to add potassium to his soil but is not sure what type of potassium to use. If you use Potassium Chloride (normally used because the price is cheap) the taste of the lucerne will be bitter. If you use Potassium Sulphate the taste of the Lucerne will be sweeter. Cows prefer sweeter Lucerne (so Bessie the cow told us). Another example is golf courses - make sure the potassium levels are correct. Too much potassium blocks out the manganese. You need both chemicals to be working for grass strength.

Herbicide Resistance in Giant ButtercupThere appears to be some cases of herbicide resistance in Giant Buttercup

to flumetsulam. Initially this seemed to be limited to the Golden Bay area

but there have been some cases reported in Taranaki and Woodville. The

recommendation is to rotate between flumetsulam and MCPA.

Flumetsulam is known under the following tradenames. Valdo (Nufarm Limited),

Preside (Dow Agrosciences LLC), Synergy Flumet 800 (Orion Agriscience), Aim (Ravensdown

Ltd) and Decision(Rainbow & Brown Ltd).

The above tradenames are registered tradenames of the company in brackets.

COBBER – THE UNSUNG HEROGreat for Cali thistles!!Before you read too much further Cobber (clopyralid 300g/L) is one of those products, which for fairly silly reasons in my opinion, require a Certified Handlers certificate (or Approved Handler if your certificate is current), to even buy the product. We can’t sell it to you unless you can give us your certificate number.

Also Cobber is not to be used for treating turf that will be mown and the clippings used for making compost; or made available for collection for, or deposited at, a municipal green waste recycling centre. It is also not to be used for lawns or home gardens.

That all said - Cobber will translocate really well compared to say 2,4-D which doesn’t move as efficiently through the extensive roots systems of some of the perennial weeds, which makes Cobber a great choice for use on Californian thistles and all the other thistle varieties as well.

The boffins reckon the sugars stop flowing up to the foliage of Californian thistles once the shoots are well-established in spring. Once the first flower buds start to form the sugars flow back to the roots so Cobber will very effectively move down into the roots if all the foliage is

sprayed. You do need to be spraying low down on the Cali’s though as otherwise most herbicides will tend to head towards the flower rather than the roots. It is all to do with what is the strongest “sugar sinks” (something for another article).

The active ingredient of Cobber, clopyralid, has a structure very similar to that of dicamba. So behaves in a similar way. It is used for clover control in combination with glyphosate or paraquat. Although it controls a slightly narrower range of weeds than dicamba, it gives excellent control of most Asteraceae and legume weeds, so is also great for Californian thistle.

It is used selectively in a number of areas, including pasture, forage brassicas, pines, asparagus, cereals and turf, where it is commonly used to control the troublesome Onehunga weed. It is though, persistent in the clippings and so it is not allowed to be used in clippings that are going to be used for composting.

APPLICATION RATES: 1-2L in 100-200L water per hectare, or 100-200ml per 100L for spot spraying.


HOW TOXIC ARE HERBICIDES?Although herbicides are chemicals and all chemicals should be treated with respect there needs to be some perspective given as there is a mountain of misinformation being spread by people that really don’t know what they are talking about. I hear it all the time on talkback and it makes my blood boil.

Below is a table which shows the relative toxicity of the active ingredients in a number of common herbicides. To provide some reference I have also included some commonly known products such as salt, caffeine and nicotine as well as some well-known actual poisons such as strychnine, arsenic and 1080 poison.

The LD50 toxicity is based on the mg of the product (active ingredient) needed per kilogram of body weight to kill half the rats tested.

* the lower the number the more toxic

Let’s boil this down and use the currently very topical glyphosate or Roundup as our example. The figures in the table are for the active ingredient, so 5,400mg of active ingredient per kg of bodyweight. Assume that glyphosate has the same effect on humans as on rats.

Allow for a reasonably conservative 60kg human. To kill one of two 60kg humans they would need to consume 324,000mg of the active ingredient in a reasonably quick time. This would mean consuming 900,000mg of the neat Glyphosate 360. This is nearly 1 litre of Glyphosate 360 that would need to be drunk. This would be unlikely but there have been cases where people put chemicals into household containers like water bottles and then grab them by mistake. Even under these circumstances you might get sick but would be unlikely to consume enough to kill you.

Once diluted to be used for spraying the numbers get even more silly. Even caffeine which is much more toxic than glyphosate you would need to consume more than 200 cans of Coke or 75 cups of coffee to get poisoned by the caffeine.

So let’s now dilute Glyphosate ready to spray. Even at the high blackberry rate you are spraying at around 10 litres of Glyphosate 360 per ha. Let’s assume your spray tank is 400L and this does one hectare. So if drinking the made up tank spray you would need to drink around 36L of tank mix. I couldn’t do it with beer so pretty unlikely I could stomach 36 litres of Glyphosate tank mix!

Take it one step further. Assume you let stock onto the sprayed pasture by mistake. Let’s use sheep and assume they also weigh 60kg to keep the math simple. To get a toxic dose they would need to eat 900m2 of just treated pasture. Not all the herbicide gets onto the grass and what does is absorbed quite quickly and starts to deactivate in the plant as it starts to kill. Glyphosate is deactivated in the soil as well. So even if all the glyphosate was sitting on top of the pasture the 900m2 of pasture would have to be consumed within a few hours. Just not possible.

Many plants and weeds produce more toxins and in higher levels than the chemicals being applied. Docks are a perfect example of this.

In an ideal world we would love to not have to use any chemicals, herbicides, insecticides, pesticides etc. but the environmental goals that we all share I think need to be balanced with practicality and common sense.

So in these days of environmental virtue signalling and PC correctness I hope this adds some sanity and perspective to what is not a simple issue.


BESSIE N ANGUS ON SEAWEEDHey Angus, what’s with the stuff Harry is sticking in the trough and spraying on the pasture.

Seaweed Extract, I believe. Tastes gooooood.

What’s it supposed to do?

Makes the grass grow and pumps a bit of nutrition into our tummies. Has some rather unique properties.

Like what?

Well, you remember Gilly having all those blisters on her face which she gorged herself silly.

Yep, I remember no one would go near her. I thought she got something from you.

Nah, wasn’t me. She got a load of eczema from eating too many spores.

Have a look at her this year. Clean as a whistle.

And you put that down to the seaweed eh.

Yep, Graeme next door used it and told Harry to try it.

I might sneak over and see if I can have a taste.

Getting product from our place to your place safely and quickly has always been one of our strengths and for orders over $100+GST ($115 incl. GST) we do this for no extra cost. Yep gratis.

We also love smaller orders and sometimes you only need a bit to keep you going but the cost of getting these smaller orders out to you can sometimes eat up all the profit so that’s why a few years ago we looked at the cost of freight on smaller orders and put in a nominal freight charge on small orders.

Of course with increases in fuel, labour and compliance costs the courier companies have increased their rates and on these smaller orders we are going backwards again and you know we get slugged for delivering to rural addresses so we have had to slightly increase the freight cost

on orders under $115 incl GST. This will now be $7.50 starting from 14th October (and we are still subsidising the cost a bit into most areas).

But on the bright side we are sucking up all the increases and are still delivering to you for FREE if your order is $115 or more.

Foeniculum vulgarae

DESCRIPTION

Fennel is a quite tall plant, growing up to 2 metres. It’s not often a problem on developed agricultural land, but is very commonly seen on roadsides and in waste areas, including vacant sections.

It produces large clusters of bright yellow fl owers through the summer and autumn. The fl owers themselves are individually very small, but as they grow at the tops of the stems in prominent umbels (umbrella-like clusters), the fl owering plant is visually spectacular, especially when growing in thick clumps.

The other telling recognition feature is the distinctly aniseed smell of the leaves, which are often used as a cooking or garnishing herb with fi sh recipes, and in several other cooking and baking applications. This is a bit of a surprise, because fennel was for a time classifi ed as a noxious plant due to its similarity to the poisonous hemlock. It is, however, not poisonous, and remains a welcome visitor to many a kitchen and dining table.

Fennel is a perennial plant, growing from a woody and bulbous root system. It produces many erect, shiny, ribbed stems covered with fi nely divided feathery leaves. The leaves die back in the winter months.

It also produces fruit in the form of small oval capsules, about 4-5mm long, and dark brown in colour.

HABITAT

The NZ distribution of fennel is extensive. It’s found through the entire North Island, and most of the South Island (except for the southern and south-western parts). The plant originated from Europe.

Because it is not normally a problem on developed or actively-used agricultural land, but rather inhabits the unused places, fennel is more of a cosmetic concern than a serious threat to farm production. However, it does tend to multiply if left

MANUAL CONTROLIndividual plants can be grubbed out successfully. Make sure you remove the root system as well, and it’s best to then remove all plant material off the site.

HERBICIDE CONTROLFennel is quite susceptible to common herbicides, and can be sprayed any time that it’s actively growing. The ideal time will be spring and summer.

Spot SprayingAll situations where spraying is required will be hand spraying jobs, whether the fennel is present in isolated clumps or large patches of growth.Several herbicides are effective.• Granny at 45g/10L water. or

Glyphosate 360 at 100ml/10L water.These are great when you want to totally spray out the affected site, and grass damage from overspray is not a concern. Or you can use selectively and preserve grass and clover If you can apply using a Weed Wiper.

• GrassMate at 60ml/10L water.Where you want to kill just the fennel (and other susceptible weeds) but leave the grass. GrassMate will damage clover.

• Triclo at 60ml/10L water.Where you want to kill the fennel (and other weeds) but leave the grass. Clover will get heavily knocked back.

In all cases when spraying, for best results add SprayWetter penetrant at 10ml/10L water to ensure thorough penetration of the herbicide into the plant.

unchecked, and soon dominates the site. For that reason, in many locations it remains a species you’ll want to eradicate.

Broad-leaved dock – Rumex obtusifoliusFiddle dock – Rumex pulcherClustered dock – Rumex conglomeratusDESCRIPTIONThere are several dock species in New Zealand, the most common of which (pictured) is the Broad-leaved Dock. Other species include the Fiddle Dock and the Clustered Dock. The information in this weed fi le is related to the Broad-leaved Dock, but the recommended control considerations and options are generally equally applicable to the other species.The dock is a perennial weed that normally fl owers and seeds in the spring and summer. It has large, waxy leaves up to 35cm long and 15cm wide, and grows from a single very large tap root system. Individual plants can grow to about 1 metre tall at fl owering, during which erect stalks emerge to this height, supporting small, green-to-red fl ower whorls and also the fruit, which is a green-red nut form that subsequently turns to dark brown. The seeds produced are numerous and long-lived, which means that a large dock seed bank can build up in the soil if the dock plants are not promptly controlled.The favoured growing location for docks is damp and poorly-drained areas in both pastures and crops throughout the country.The leaves of docks contain bitter tannins that make it unpalatable to cattle and horses, although it is usually readily eaten by sheep. This, plus the plant’s preference for damper soils, often sees docks become a particular problem on dairy farms.MANUAL REMOVALIndividual plants are very diffi cult to pull out successfully due to the extensive and strong tap root system. The plant will in any case readily regrow from the remaining portions of a severed or broken tap root. Grubbing out is also rarely practical for the same reason; it is practically impossible to remove all of the viable tap root with a grubbing tool.MOWINGMowing paddocks with signifi cant dock infestation is not recommended because virtually every severed stalk will regrow.CULTIVATIONHeavily-infested paddocks that are cultivated for cropping or resowing will usually be seriously reinfested from tap root regrowth and also seedling growth. It is therefore essential that this be combined with pre-cultivation herbicide treatment (see Herbicide Control section).

HERBICIDE CONTROL

Docks, especially after the seedling stage, are relatively diffi cult to kill with many common herbicides. The best time to control docks with herbicides is in the spring, when the dock plant is actively growing, but before the seed head has developed. This is usually from October to December. It is very important to control docks in new pasture, due to the tendency of the rapidly growing dock plants to out-compete the immature pasture species.

Boom Spraying• 2,4-D Granules at 2.5kg/Ha will control

seedling (up to 4 leaf stage) docks safely in new pastures. If the docks in a new pasture are not controlled at this early stage, there will be no viable control options until the grasses have matured. And by that time the docks will have seriously degraded the pasture quality. Note that 2,4-D Granules will not control dock plants regrowing from old tap root stock.

• Ranger at 20g/Ha will control both seedling and mature docks in established pasture and in cereal crops. Subsequent spot spraying of some larger plants may be required to obtain total control. Best results are obtained by spraying 1-2 weeks after grazing, which ensures the maximum number of dock seedlings have emerged. There will be some yellowing and reduction in pasture vigour after using Ranger but complete recovery including of clovers will normally occur if growing conditions are reasonable.

Ranger at 20g/Ha should also be added to glyphosate sprays used for spraying out pre-cultivation if docks are present in the old pasture. Glyphosate used alone at the usual spray-out rates will not give adequate control of the docks.

Spot Spraying• GrassMate at 6m/L applied anytime,

but preferably when growing actively, to whole plant. Grass-friendly, but will kill clover.

Spot Treatment• Buckshot granules applied dry at 2g to the

crushed centre of each plant.

It has large, waxy leaves up to 35cm long and 15cm wide, and grows from a single very large tap root system. Individual plants can grow to about 1 metre tall at fl owering, during which erect stalks emerge to this height, supporting small, green-to-red fl ower whorls and also the fruit, which is a green-red nut form that subsequently turns to dark brown. The seeds produced are numerous and long-lived, which means that a large dock seed bank can build up in the soil if the dock plants are not promptly controlled.The favoured growing location for docks is damp and poorly-drained areas in both pastures and crops throughout the country.The leaves of docks contain bitter tannins that make it unpalatable to cattle and horses, although it is usually readily eaten by sheep. This, plus the plant’s preference for damper soils, often sees docks become a particular problem on dairy farms.MANUAL REMOVALIndividual plants are very diffi cult to pull out successfully due to the extensive and strong tap root system. The plant will in any case readily regrow from the remaining portions of a severed or broken tap root. Grubbing out is also rarely practical for the same reason; it is practically impossible to remove all of the viable tap root with a grubbing tool.MOWINGMowing paddocks with signifi cant dock infestation is not recommended because virtually every severed stalk will regrow.CULTIVATIONHeavily-infested paddocks that are cultivated for cropping or resowing will usually be seriously reinfested from tap root regrowth and also seedling growth. It is therefore essential that this be combined with pre-cultivation herbicide treatment (see Herbicide Control section).

HERBICIDE CONTROL

Docks, especially after the seedling stage, are relatively diffi cult to kill with many common herbicides. The best time to control docks with herbicides is in the spring, when the dock plant is actively growing, but before the seed head has developed. This is usually from October to December. It is very important to control docks in new pasture, due to the tendency of the rapidly growing dock plants to out-compete the immature pasture species.

Boom Spraying• 2,4-D Granules at 2.5kg/Ha will control

seedling (up to 4 leaf stage) docks safely in new pastures. If the docks in a new pasture are not controlled at this early stage, there will be no viable control options until the grasses have matured. And by that time the docks will have seriously degraded the pasture quality. Note that 2,4-D Granules will not control dock plants regrowing from old tap root stock.

• Ranger at 20g/Ha will control both seedling and mature docks in established pasture and in cereal crops. Subsequent spot spraying of some larger plants may be required to obtain total control. Best results are obtained by spraying 1-2 weeks after grazing, which ensures the maximum number of dock seedlings have emerged. There will be some yellowing and reduction in pasture vigour after using Ranger but complete recovery including of clovers will normally occur if growing conditions are reasonable.

Ranger at 20g/Ha should also be added to glyphosate sprays used for spraying out pre-cultivation if docks are present in the old pasture. Glyphosate used alone at the usual spray-out rates will not give adequate control of the docks.

Spot Spraying• GrassMate at 6m/L applied anytime,

but preferably when growing actively, to whole plant. Grass-friendly, but will kill clover.

Spot Treatment• Buckshot granules applied dry at 2g to the

crushed centre of each plant.
