六种生物农药防治加工番茄棉铃虫试验

目的]研究六种生物源农药对加工番茄棉铃虫的防治效果,筛选出更加适合番茄制品出口食品安全要求的高效农药.方法]采用田间小区试验,比较六种生物源农药对加工番茄棉铃虫的防效差异.结果]施药后第10 d,各药剂的防效分别为:48;多杀菌素悬浮剂93.28;、600×108PIB/g棉铃虫核型多角体病毒水分散粒剂91.44;、16 000 IU/mgBT可湿性粉剂83.88;、0.3;印楝素乳油73.44;、5;天然除虫菊素乳油68.21;、0.36;苦参碱水剂43.89;,对照化学药剂2.5;高效氯氟氰菊酯水乳剂为86.67;.结论]48;多杀菌素悬浮剂、600×108PIB/g棉铃虫核型多角体病毒水分散粒剂、16 000 IU/mgBT可湿性粉剂、0.3;印楝素乳油、5;天然除虫菊素乳油5种生物源农药的防效较好,且更适合加工番茄产品出口的食品安全要求.

The Experiment on Using Six Biologic Pesticides to Prevent Cotton Bollworn in Processing Tomato Field

【Objective】Using six kinds of biologic pesticides to study their prevetion effect to cotton bollworn in Processing Tomato field and screen out effective biologic pesticides which adapt to the rule about food safty.【Method】Compared the prevetion effect of six biologic pesticides to cotton bollworn in field plot experiment.【Result】The tenth day after using these pesticides,the provention effect of 48%Spinosad SC is 93.28%,60 billion PIB/g cotton bollworm NPV WG is 91.44%,16 000 U/mg BT WP is 83.88%,0.3%azadirachtin EC is 73.44%,5% crude pyrethrins EC is 68.21%,0.36% matrine AS is 43.89%,control chemic pesticide 2.5% Lambda-cyhalothrin EW is 86.67%.【Conclusion】The prevetion effect of 48%Spinosad SC,60 billion PIB/gcotton bollworm NPV WG,16 000 U/mg BT WP,0.3% azadirachtin EC and 5%crude pyrethrins EC are better,and they are adapt to the requirement about food safty.
