PASS Agricultural silicone surfactant from Profirst
- 1. Super Spreader Agricultural Silicone Surfactant Shanghai Profirst Co., Ltd. Scan here to visit our web
- 2. Main contents The work way of pesticides on surface of plants Super Spreader “PASS“ Agricultural silicone surfactant How to use “PASS” ? 6/5/2017 “PASS” Showcase Other PASS series
- 3. When spraying pesticides 6/5/2017 Spraying Coverage & Rain fastness Penetrate & Translocation Wetting & Spreading Retention More Retention More Coverage & Ensure final efficacy
- 4. If use pesticides directly on targets Can not be absorbed immediately. It’ll take hours to be permeate into the organizations of the plant. Less than 0.03% finaly acts on the targets. 6/5/2017 Easily lost to the field and washed away by rain, which cause amounts of run-off.
- 5. Any solutions? Spraying more? Cause a waste of pesticides 6/5/2017
- 6. Using better sprayer? Better than the former 6/5/2017
- 7. Adding additives? The best, and most effective way 6/5/2017
- 8. Possibility of adding surfactants Skin absorption Stomatal absorption 6/5/2017 Critical surface tension 25mN/m
- 9. 6/5/2017 Possibility of adding surfactants “Skin absorption” (left) can be changed into “Stomatal absorption” (right) only if the surface tension less than 25mN/m. Surfactant, which can decrease the surface tension of solvents, can be used as the additives.
