Analysis of the Effectiveness of Different Pesticides (Combinations) in Controlling Sclerotinia Stem Rot in Rapeseed
Abstract：To screen for efficient pesticides for controlling Sclerotinia stem rot in rapeseed, this study selected five pesticide combinations for a field comparison trial. By investigating disease incidence, disease index, control effectiveness, and yield indicators, the differences in efficacy among different pesticide combinations and their effects on rapeseed growth were analyzed. The results showed that all five tested pesticides had some level of effectiveness against Sclerotinia stem rot. Among them, the treatments with 200 g/L fluxapyrodine suspension + 25% prochloraz emulsifiable concentrate, and 200 g/L fluxapyrodine suspension + 25% prochloraz emulsifiable concentrate + Yishi Duojin performed relatively better, with control efficiencies of 88.7% and 81.7%, respectively. Compared to the blank control, these treatments increased yields by 14.6% and 20.6%, respectively, and generated additional benefits of 129 yuan/667m² and 185 yuan/667m². The results show significant yield increase and economic benefits, indicating that these treatments are worth promoting and applying.
