3, in the application of growth regulator 
Silicone surfactants can reduce the use and improve the use effect. For example, gibberellin is widely used in citrus, but it is easy to produce antagonism with citrus, the application of agricultural organic silicon additives can greatly improve the efficacy of gibberellin, gibberellin dosage can also be reduced to 1/10; Adding organosilicon additives to enrobutrazol can improve its wettability and efficacy, reduce the use of enrobutrazol, and reduce the use cost of enrobutrazol 
Application of 4 in insecticide and acaricide 
The stoma of an insect is very similar to the stoma of the leaf. Silicone surfactant can reduce the surface tension of the solution, make the liquid permeate into the trachea of insects, so that it is of great significance as an insecticide additive and synergist. For example, with the addition of organic silicon additives, the control effect of 20% carbosulphobine ec (45g /hm2) on aphids was similar to that without the addition of organic silicon additives (75g/hm2), and the actual field dose of 20% carbosulphobine EC could be significantly reduced.
