摘要
以百合根腐病为防控靶标,开展百合根腐病高效低毒药剂筛选,通过田间小区试验测定了 4 种药剂对百合根腐病的田间防效,调查结果表明:240 g/L丙硫菌唑·嘧菌酯·咯菌腈FS对百合根腐病的田间防效最好,达到 80.1%,链霉菌BHT-5-2 菌剂对百合根腐病具有较好的田间防效,达到 66.4%,而 30%咪鲜胺·咯菌腈SE和 30%氟吡菌胺·精甲霜灵SE对百合根腐病的田间防效仅分别为 23.0%、14.2%,防效很差,没有生产应用意义.
Abstract
The highly efficient and lowly toxic agents against lily root rot(LRR)were screened with LRR as the control target and the field control effects of four agents against LRR were determined by field plot experiments.According to the results,240 g/L prothioconazole-azoxystrobin-fludioxonil(FS)displayed the best control effect,exhibiting an LRR inhibition rate of 80.1%,and Streptomyces BHT-5-2 also had a good effect with an inhibition rate of 66.4%.However,the inhibition rates of 30%prochloraz-fludioxonil(SE)and 30%fluopicolide-metalaxyl-M(SE)were only 23.0%and 14.2%,respectively,showing poor control effects and no significance for production application.
