ACTION MECHANISM OF NEW OIL EMULSION MIXED INTO ATRAZINE

Wang Jinxin (Dept. of Plant Prntection. Shandong Agri. Univ., Taian. China 271018) Li Jin (Dept. of Plant Protection. Shenvang Agri. Univ., China) Qin Na (Yantai Agricultural School, Shandong, China) Liu Ping (Fushun Pesticide Factory. Liaoning, China)  
Action mechanism of the new oil emulsion mixed into atrazinewas determined by physical property tests, scanning electronmicroscopy and physiological target tests. The result showed thatthe adjuvant decreased the surface tension and contact angle ofspray droplets, resulting in better coverage and delaying the spraydroplets to be dryed. The adjuvant solubilized and softened-theleaf cuticle, increasing electric conductivity of the weed leaf,consequently, improving permeability and absorption of atrazine.With help of the adjuvant, atrazine speeded up inhibition ofphotosynthesis of the weed plants, resulting in sooner dying ofthem.
