  pesticide synergist  cas no.:67674-67-3, silwet 408 Nonionic silicone QS-302

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 agrochemicals.                


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 240 can replace it,Proposes to dilute ten thousands times to compare with similar products.  


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%  


Herbicide: 0.025%-0.15%                          


Pesticide: 0.025%-0.1%  


 Bactericide: 0.015%-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.


Manily Application


biological pesticide spray mixture liquid such as pesticide, bactericide, herbicide, foliar fertilizer, plant growth regulator, etc,  


Package and shipment


200kg/steel drum, 25 or 50kg/plastic drum, to store in a cool place. To prevent direct sunlight, Non-dangerous goods transportation.
