在保护地利用昆虫病原真菌赤座霉菌(Aschersonia)防治粉虱与使用防治其它病虫害的农药有着密切关系。在有关化学药剂对赤座霉菌孢子影响这方面有着完全不同的报导。有的资料指出,波尔多液、石硫合剂、1605和乐果对赤座霉菌孢子没有极有害的影响,所以上述制剂可以和赤座霉菌同时使用。相反,有些作者报导,波尔多液、福美双、代森锌和石硫合剂对赤座霉菌有致死作用,因此其菌与农药不能同时使用,也研究了赤座霉菌与农药同时使用的可能性。他确定赤座霉菌孢子与多菌灵、克林菌、敌螨普、粉霉菌素等2小时的接触对萌发影响不大。但20小时的接触对赤座霉菌孢子的发育就有不利的影响,在5～9天内卽表现出来,其中毒性最大的是多菌灵和敌螨普。
The use of Aschersonia, an insect pathogenic fungus, to control whiteflies in the protected areas is closely related to the use of pesticides to control other pests and diseases. There is a totally different story about the effects of chemicals on the spores of Helicoverpa armigera. Some sources point out that Bordeaux mixture, limestone, 1605 and dimethoate do not have extremely harmful effects on the spores of CI. Therefore, the above-mentioned preparation can be used simultaneously with CI. On the contrary, some authors have reported that Bordeaux mixture, thiram, dezincin, and lime sulfur compounds have a lethal effect on Clostridium jejuni. Therefore, their bacterium and pesticide can not be used at the same time, and the possibility of simultaneous use of Clostridium pest and pesticide was also studied. He determined that the contact of 2-hour exposure of Pedicort sp. With carbendazim, Klinjit, Adriamycin, and powdery mildew had little effect on germination. However, the 20-hour exposure had adverse effects on the development of conidial mold spores and appeared within 5 to 9 days, with the most toxic being carbendazim and propamocarb.
