Studies of Gongzhulingmycin on Muskmelon Growth Promotion and Its Control Effect on Fusarium Wilt

摘要

In order to elucidate the relationship between the pathogen carriage rate in seeds of muskmelon(Cucumis melo L.) and the incidence rate of Fusarium wilt of muskmelon(FWM), as well as to identify potential biological control agents against FWM, this study conducted both pot and field experiments to evaluate the efficacy of Gongzhulingmycin on FWM and its impact on muskmelon yield. The results indicated that the pathogen carriage rates of different species in muskmelon seeds varied significantly, showing a positive correlation with disease incidence during the seedling stage. The results from pot tests indicated that in comparison to the control, disease indices were significantly reduced following treatment with prochloraz and 100 times Gongzhulingmycin at both 7 days and 14 days post-emergence of FWM symptoms. Concurrently, root growth was enhanced. Field experiment outcomes demonstrated that relative to the control, there was a decrease in FWM incidence during the fruit-setting stage, along with an increase in theoretical output per square kilometer for muskmelon. Although the efficacy of Gongzhulingmycin against FWM was lower than that observed for prochloraz, it exhibited significant effects on biomass enhancement and disease resistance. Therefore, it showed promise as a potential biological control agent for managing FWM.
