Silicone surfactant for agricultural application CAS:67674-67-3
Model NO.: QS-302
1 .Chemical Name--modified polytrisiloxane
2 .Cas No.:67674-67-3/H.S No.:39100000
3.Countertype product:Silwet 408 & Break Thru 240
4. Product characteristics- QS-302 is organic silicone surfactant/adjuvants for
Due to its low surface tension, after adding it to agro-chemicals,
1) ,quickly and thoroughly enhance the agro-chemical’s
penetrability, dispersity, absorption, tranportion on the plant.
The spreading area and speed of the agro-chemicals on the leaf of
plant can be increased greatly. Especially to those leaves with
waxy surface, QS-302 can infiltrate and penetrate the plant’s
stomatas thus moisten them quickly.
2),By using the adjuvant QS-302,the agrochemical can be withstand raining-wash, the agro-chemcial
can be sprayed even in the raining days.
3),QS-302 can increase the agro-chemical’s spraying area, thus which
can save the dosage of agrochemical by 20-30%, reduce
agro-chemical’s spraying amount and ultimately save cost and
protect our environment.
4),QS-302 is non-toxic, environmental friendly adjuvant.

Usage way and dosage
1),spraying mixture in drum (Tank mixture)
the quality is similar as Silwet408,Break Thru 240can replace it,Proposes to dilute ten thousands times to compare with similar
In general, add Qs-302(5000~3000times) 3~5g in every 15kg spraying
liquid. If it needs to promote the adsorption of systemic
pesticide, increase the function of pesticide or reduce the amount
of spray further, it should add the usage amount properly. In
general, the amount is as follows:
Plant promote regulator: 0.025%-0.05%
Fertilizer and trace element: 0.015%-0.1%
When using, first dissolve the pesticide, add Qs-302 after the
uniform mixture of 80% water, then add water to 100% and mix them
uniformly. It is advised that when using the adjuvant, the water
amount reduced to 1/2 of the normal (suggested) or 2/3, average
pesticide usage reduced to 70-80% of the normal. Using the small
aperture nozzle will quicken the spray speed.
2) Original formulationsof Pesticides
the quality is similar as Silwet408, can replace it.
Adding Qs-302 to the original formulations of pesticide, we suggest
the amount is 0.5%-8%. Adjust the PH value of the pesticide
prescription to 6-8. The user should adjust the amount of Qs-302
according to different kinds of pesticide and prescription to reach
the most effective and most economical result. Do compatibility
tests and stepwise tests before usage.
biological pesticide spray mixture liquid such as pesticide,
bactericide, herbicide, foliar fertilizer, plant growth regulator,
