摘要: 为明确不同药剂对多年生水稻主要病虫害的防治效果,根据多年生水稻品种PR23主要病虫害发生情况,制定不同的防治方案,于2017年进行了田间药效试验。结果表明,70%吡虫啉水分散粒剂、40%福戈水分散粒剂对多年生水稻稻飞虱的田间防治效果高于25%阿克泰水分散粒剂+77.5%敌敌畏乳油混配液,前二者药后5 d防治效果达到最高,分别为91.00%、86.84%;3%呋喃丹颗粒剂对多年生水稻稻纵卷叶螟的田间防治效果达90%以上,40%福戈水分散粒剂对多年生水稻稻纵卷叶螟的田间防治效果超过70%,二者防治效果显著高于16 000 IU/mg苏云金杆菌;20%井岗霉素可溶性粉剂+60%嘧菌酯水分散粒剂+70%氟环唑水分散粒剂混配施用对多年生水稻纹枯病、稻曲病有较好防治效果,防效分别达83.45%、84.45%。

Abstract:  In order to clarify the effect of different pesticides on main diseases and pest insects of peren nial rice,according to the occurrence of main diseases and pest insects of perennial rice,different control schemes were formulated.Field efficacy trials were carried out in the year of 2017.The results showed that 70% imidacloprid WG and 40% virtako WG had higher control efficiency on rice planthopper than the liquid mixed with 25% actara WG and 77.5% dichlorvos EC in perennial rice field,and the control effects reached the highest level on the fifth day after spraying,which were 91.00% and 86.84%,respec tively.The field control effects of 3% carbofuran GR and 40% virtako WG on Cnaphalocrocis medinalis exceeded 90% and 70%,respectively,which were both significantly higher than that of 16 000 IU/mg Bacillus thuringiensis.Moreover,mixed 20% jinggangmycin SP,60% azoxystrobin WG and 70% epoxi conazole WG application had good effect on sheath blight and smut of perennial rice,and the control effi ciency was up to 83.45% and 84.45%,respectively.
