Application and Prospect of emulsifier in the field of pesticide
Release Date：2013-11-21 Source：admin Views：1339
As we all know , emulsifiers and widely applied in the field of pesticides is no exception, with everyone today small should take a look emulsifier Application and Prospect of pesticides in the field :
Emulsifiable concentrate formulation of the pesticide emulsifier is indispensable in the preparation of the main component , and its main role is to impart the necessary surface active cream , cream to make microscopic oil droplets uniformly dispersed in water to form a relatively stable emulsion. Mainly non -ionic emulsifier and anionic mixtures for the preparation of emulsifiable concentrates , typically by emulsifying properties and effects of the pesticide formulation to select an emulsifier , the emulsifier is usually used : polyoxyethylene- fatty alcohol ethers, styryl phenol polyoxyethylene ethers , polyoxyethylene alkylphenol ether sulfosuccinate , polyoxyethylene nonylphenol ether , polyoxyethylene castor oil , polyoxyethylene- fatty acid esters, alkyl aryl sulfonate salt , such as dairy farming 2201 , dairy farming 0203B, Nongru 62022B, Nongru OX22568, dairy farming OX28686 so on. These complex emulsifier have good emulsifying properties , but they are prepared with relatively stable emulsion .
Quality of pesticide formulations and formulations of pesticide products is a key factor in determining the value and effectiveness of various types of field efficacy decades results show that by adding a suitable emulsifier , can significantly improve the wetting , distribution , dispersion, retention and penetration performance, reduce spray liquid wind ( airflow ) drift, to prevent or mitigate damage to adjacent sensitive crops , beneficial liquid spreading and adhesion in the foliage , reducing pesticide formulations of UV on the decomposition of the active ingredient , to improve biological activity, significantly reduce the amount of pesticide active ingredients , reduce costs , protect the purpose of the ecological environment. On the other hand , improved varieties by changing the physical properties of emulsifiers original drug , delaying development of resistance and prolong the life of the hard-won pesticides , making it better play efficacy.
