BREAK-GARD® adjuvants as soil amendment improve wetting & penetration of repellent soils due to very low surface tension

Improved infiltration of water reduces run-off of water, nutrients and soil.

Residual moisture

on surface of loamy

soil was reduced.

Thereby the

potential for

diseases and water

losses by

evaporation are

diminished.

Treated plants may

have an increased

photosynthetic

activity. Leaf

number was

increased and the

plants had a more

healthy look.


With addition of BREAK-GARD® IR 100 water infiltration was quicker

Addition of BREAK-GARD® IR 100 leads to

• Higher penetration and infiltration of water in soil

• A better wetted root zone (=deeper soil layers)

• Lateral wetting provides a more homogenously

wetting of soil

• Higher water retention even in drought situation

• Better rewetting of the root zone area after short

droughts

BREAK-GARD® IR 100

� reduces evaporation from the soil surface

� maintains moisture in the root zone

� increases the water & nutrient availability in the

root zone


BREAK-GARD® IR 100 improves the vertical and horizontal waterdistribution in the soil

*Unpublished data of CRA institute, Rome, Italy

Soil moisture in a situation where the soilhave been irrigated after a drought*: untreated (Control / CNT / top) and treated(Surfactant / SURF / bottom) soil fromsurface down to 35 cm in a length of 80 cm‘

Test in a growth chamber with lettuce*

• Growth in loamy soil rich in organic matter

salted to a final Na+ concentration of 100

meq/l

• Higher quality of lettuce compared to the

untreated control:

� more regular and dense head

� greener mature leaves

� higher density

� less diseases


BREAK-GARD® IR 100 addition to salty loamy soil leads to quality improvements in lettuce

Unfertilized lettuce plants 35 days after transplanting (application of BREAK-GARD® IR 100 by irrigation at two

different doses respect to the control).

Application of BREAK-GARD® IR 100

� led to more tomato flowers

� increased the number of harvested tomatoes and

the fruit weight

� reduced apical rot indicating a better calcium

availability and a better tomato quality

� increased number and fruit weight of bell pepper

Positive effects were slightly higher on heavy clay soil

with poor soil drainage – however also on loose clay

soil the effects were visible

With 3 l//ha*season) the needed application amount

is very low (tested between 0.5 – 2 l/ha, one to six

times


BREAK-GARD® IR 100 showed positive effects on yield in first field trials with tomatoes and bell pepper

BREAK-GARD® IR 100

• shows the same extraordinary high surface activity in water than conventional trisiloxanes

• is clearly soluble in water, water based fertigation and foliar nutrient formulations leading to high solution stability and product activity up to temperatures of 53 °C (cloud point)

• forms micelles in water which ensures solubilizing of fats, oils and particles

Conventional trisiloxanes forms bilayer aggregates in water leading to already turbid appearancein water at room temperature and to reduced surface activity with separation from water beyondcloud point (~42 °C)


BREAK-GARD® IR 100 is a unique trisiloxane as it is highly active also in hot summers

BREAK-GARD® IR 100

� Is not ecotoxic

� Does not contaminate ground water

� Does not leave residues in plants

� Is not phytotoxic to plants

� Is readily biodegradable (OECD 301 F)

� Not dangerous according to transport regulations

BREAK-GARD® IR 100

� prevents soil erosion and nutrient run-off which can cause eutrophication of rivers and lakes

� reduces soil salinization

� increases water use efficiency


BREAK-GARD® IR 100 is readily biodegradable and has a favorable ecotoxicological profile

BREAK-GARD® IR 100


BREAK-GARD® IR 100 leads to a constant wetted root zone, to betterquality and to higher yields

• Is applied in low dosage

• Effectively enhances the penetration and

infiltration of irrigation water and rainfall into

the soil profile

• Reduces evaporation from the soil surface

• Improves maintaining a more homogenous

soil moisture in the root zone

• Increases yield and quality by optimizing

plant nutrition

• Is highly active even at high temperatures

• Is environmentally benign

Dosage of BREAK-GARD® IR 100

� 1 L/ha up to 2 L/ha for applications in vegetables, grapes, fruits, ornamentals.

� Repeat application with a minimum interval of 10 days or longer, up to 6 times per

growing season; irrigate between application cycles as usual.

Application of BREAK-GARD® IR 100

� applied through irrigation systems, like drip irrigation, micro-sprinkler, or overhead irrigation

systems (including center pivot systems). In cases of injection into the irrigation systems,

concentrations of lower than 0.02 % (20 ml/100 L) should be avoided.

� used from the beginning of irrigation cycle. Onto bare soil it is applied before planting, or

on cultivated broad acreage crops and row crops. It can also be applied with normal boom-

spraying equipment at 1 L/ha in 1000 L/ha water; either immediately before rainfall or

before sprinkler or pivot irrigation.

� can be combined with nutrients, and is compatible with micro-nutrients and beneficial

microorganisms which are applied with irrigation / fertigation systems.


BREAK-GARD® IR 100 is applied in low dosage
