摘  要:通过对多种助剂的筛选,采用直接乳化法确定了40%叶菌唑·咪鲜胺悬乳剂的优选配方:叶菌唑10%、咪鲜胺30%、溶剂油150#8%、G50002%、Agrilan7883%、FTRT E10456%、黄原胶0.1%、硅酸镁铝0.9%、丙二醇5%、卡松0.2%、消泡剂0.2%,去离子水补至100%。该制剂冷储和热储稳定性较好,悬浮率≥98%,分解率≤1%,各项指标均符合悬乳剂的要求。在一定稀释倍数范围内,随着药液浓度的降低,表面张力逐渐增大,固-液界面黏附力最大值随之变小,雾滴粒径随之变大。田间药效试验表明,40%叶菌唑·咪鲜胺悬乳剂1000倍液喷雾防治小麦赤霉病,药后7、30 d的防效分别为83.3%和93.8%,优于对照药剂,是防治小麦赤霉病的有效药剂。After the screening of different adjuvants,the optimum formula of metconazole·prochloraz 40%SE was determined by direct emulsification method.The compositions were metconazole 10%,prochloraz 30%,solvent oil 150#8%,G50002%,Agrilan7883%,FTRT E10456%,xanthan gum 0.1%,magnesium aluminum siliacte 0.9%,propylene glycol 5%,kathon 0.2%,defoamer 0.2%,and deionized water to 100%.The formulation showed good stability under cold and heat storage condition.The suspension ratio was higher than 98%while resolution ratio was lower than 1%.All indexes were in accord with the requirements for suspension emulsion.In a certain dilution range,as the decreased of liquid concentration,the surface tension gradually increased,the maximum adhesion force of the solid-liquid interface became smaller,and the particle size of fog droplet became larger.The control effects of 1000 times dilution of metconazole·prochloraz 40%SE on wheat scab at 7,30 days after treatment were 83.3%and 93.8%,which were all superior to that of control agents.It can be used as an effective fungicide against wheat scab.
