摘要
对8种药剂对稻曲病[病原菌为Ustilaginoidea virens(Cke)Tak]的防治效果和增产作用进行了试验。结果表明,在水稻破口前和齐穗期两次喷药,30%苯甲.丙环唑乳油、43%戊唑醇悬浮剂、井冈霉素A 2%.蜡样芽孢杆菌(Bacillus cereus)1×108CFU/g水剂、20%井冈.咪鲜胺可湿性粉剂对稻曲病的防效较好,防效在81.64%以上,60%吡唑醚菌酯.代森联水分散粒剂和0.5%氨基寡糖素水剂防效较差。8种药剂对水稻均有不同程度的增产作用,增幅为3.84%~8.88%。
Efficacy and yield enhancement effects of eight against Ustilaginoidea virens(Cke)Tak were tested.The results showed that if spraying in both rice break period and complete heading stage,the control efficiency of 30% Difenoconazole · Propiconazole EC,43% tebuconazole SC,Jinggangmycin A 2% · Bacillus cereus 1×108 CFU/g AS,20% Jinggangmycin · Prochloraz WP) reached over 81.64%,while of 60% Pyraclostrobino · Metiram WG and 0.5% amino Oligosaccharins AS were not so that good.The 8 kinds of fungicide could increase yield of rice at different degrees,ranging from 3.84% to 8.88%.
