The general situation of agricultural organic silicone surfactants

1, the basic situation of surfactant introduced:
1.1 Pesticide and surfactants: processing pesticide formulations inseparable surfactant, pesticide agents (including: cream, water emulsion, microemulsion, wettable powders, soluble powders, dispersible granules, granules ) to be added to the processing of different types of surfactants. Addition of a surfactant, greatly reduces the surface tension of the solution, enhanced pharmaceutical plant or pest surface wetting, distribution and adhesion, thereby improving efficacy. Currently the application of pesticides surfactants are: polyoxyethylene fatty alcohol, alkyl phenol polyoxyethylene ethers, sulfonate, sulfonic acid esters, amides, silicone and the like. Pesticide surfactant itself does not have insecticidal and fungicidal effect, but its emulsifying properties and show significant affect the efficacy of pesticides. Currently, the active ingredient content of the same domestic agents and principal agents of multinational difference lies in the application of surfactant agents, such as: Domestic 41% difference between agent and herbicidal effects of Roundup, made 40% Dow difference chlorpyrifos and chlorpyrifos insecticidal effect, are added because of the different surfactants caused.
1.2 Application of pesticide surfactants: pesticide surfactants can usually be divided into two ways neutralizing agent is added to the pesticide application. A yes, and pesticide formulations product mix directly configured. Another is that, as a tank mix additives mixed in the fields now active. Currently, the first mix of direct aid and more types of pesticides, the application will not be covered here. The second, is now mixed with the agricultural surfactant, there are two types on the market: the first category: high gold chlorthalidone, nitrogen permeability function ketones such as having a main component of agricultural aid. Henan Xinxiang companies represented several high gold Pharmaceutical products: diamond, gold, silver, see kill bacteria. The second type: the three-modified silicone (eg: Fairland 2408, Silwet 408, B- 204, S-309) as a main component an organic silicon compound from the agricultural surfactant. Year high gold chlorthalidone and other current mix additives, not only has good permeability, there is a good show significant.
