Title: Toxicity Test of Ten Fungicides to Monilinia fructicola Causing Chinese Dwarf Cherry Brown Rot
Abstract: Taking ten fungicides as materials,Chinese dwarf cherry brown rot as research object,the toxicities of 10 fungicides to Monilinia fructicola were tested by using mycelia growth rate method and spore germination method.The effective fungicides for control of brown rot of Chinese dwarf cherry were screened in the laboratory.The results indicated that the effective concetration(EC50)values of 430g/L tebuconazole SC,24%fenbuconazole SC,10% difenoconazole WG,80% Carbendazim WP,70%thiophanate-methyl WP,500g/L iprodione SC,50%procymidone WP were less than 0.700mg/L.430g/L tebuconazole SC showed the strongest toxicity to mycelia growth with the minimum EC50 of 0.027mg/L among 10fungicides,while 80% mancozeb WP showed the lowest toxicity with the EC50 of 57.645mg/L. The EC50 values of 10fungicides on spore germination were less than 2.500mg/L.500g/L iprodione SC showed the highest toxicity and its EC50 value was 0.024 mg/L.80% mancozeb WP showed the lowest toxicity and its EC50 value was 2.496mg/L.24%fenbuconazole SC,430g/L tebuconazole SC and 500g/L iprodione SC could be used for control of brown rot of Chinese dwarf cherry.
