Herbicides
• Avoid if at all possible!• Follow the label directions carefully• Do not apply in standing water• Try to stay above water-line in facilities • Never apply when rain is forecasted• Apply during calm weather, cool weather
![Page 7: Field Bind Weed ( Convolvulus sepium )](https://reader036.vdocument.in/reader036/viewer/2022062501/5681636f550346895dd44c1a/html5/thumbnails/7.jpg)
Herbicide use: discretion of local jurisdiction
Use herbicides only when a pest is uncontrollable by other, less toxic
means.

Herbicides
• DON’T reach for herbicides at the first sign of a pest, make a plan!
• DON’T apply herbicides directly to water in a Water Quality Facility
• DO apply herbicides during dry weather (mostly June-September)
• DO apply herbicides when a pest is uncontrollable by other means

Irrigation
P
• Plants are critical to the function of LID facilities• Irrigation is essential for plant establishment and health

Irrigation
P
• Irrigation especially important during establishment period(approx. 2 yrs) (true for native plants as well)
• Temporary irrigation fine for facilities with vegetation that can handle OR’s dry summers

Irrigation
PHigh exposure areas can also require permanent Irrigation after the establishment period.
• Areas near pavement
• Vast areas of minimal shade or lots of wind exposure
• areas prone to drought or fire

Irrigation
P
Water Efficiency• Hand watering and drip type irrigation systems
are the most efficient irrigation methods.• Adjusting the irrigation heads should be done
as needed to ensure water is not wasted on hard surfaces.
• Avoid irrigating when the plants do not need water.

Irrigation
P
How to Irrigate• Water must be applied in a manner that lets it
percolate into the soils and not run off the surface.
• Hand watering- Put as much down as possible until water begins to migrate along surface. Then go to the next plant.
Automated Systems• Permanent• Temporary• Utilize several short watering times or
cycle/soak.

Irrigation for Plant Establishment
P
1st YearFull irrigation schedule during the dry season to ensure good plant establishment.
2nd YearWater less than previous year to encourage plants to adapt to local climate.
3rd YearShould be little need for irrigation.

Irrigation
P
Do: • Irrigate heavily but infrequently• Water in the early morning or evening• Automate if possible• Check automated systems weekly during the
heavy irrigation season• Blow out any above ground system to winterize
Don’t:• Allow runoff • Over water• Allow overspray• Irrigate when unnecessary

Soils
• Healthy soils hold water, sediment, and pollutants
• Too much sediment (and compaction) will clog the system
• Regular maintenance will keep the facility working as designed
