In order to screen indoor effective agents for inhibiting Botrytis cinerea, Jiangxi Agricultural University Agricultural College/Jiangxi Provincial Key Technology and Quality Safety Collaborative Innovation Center for Fruits and Vegetables/Jiangxi Provincial Key Laboratory of Fruit and Vegetable Preservation and Nondestructive Testing Rate inhibition method was used to determine the inhibition rate of 12 fungicides on the mycelial growth of kiwifruit gray mold pathogen.
The results showed that 12 kinds of test agents had inhibitory effects on the mycelial growth of kiwifruit gray mold pathogens, but there were some differences among the fungicides.
Among them, 95% hexaconazole, 10% polymycin, 95% fluconazole, 95% difenoconazole, 98% epoxiconazole, 95% trifloxystrobin and 96% tebuconazole against kiwi gray mold The inhibitory effect was better, with EC50 <1.0 mg/L, followed by 97% prochloraz, 96% pyraclostrobin, 95% carbendazim and 95% sodium nitrite.
The comprehensive test results showed that 12 kinds of agents had different inhibitory effects on the growth of Phytophthora boswellia.
95% hexaconazole has the best effect and has certain application value, which can be used as a reference for storage test.
95% hexaconazole, 10% polymycin, 95% fenflurazole, 95% difenoconazole, 98% epoxiconazole, 95% trifloxystrobin and 96% tebuconazole inhibit yew gray mold The effect is better, wherein EC50 <1.0 mg / L, 97% prochloraz, 96% pyraclostrobin, 95% carbendazim and 95% sodium complexate and 96% diniconol followed.
The above research results provide a theoretical basis for the prevention and control of the occurrence and prevalence of kiwifruit gray mold and the improvement of the yield and quality of kiwifruit.
