Field Control Effect of Four Agents on Lily Root Rot
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.
