Toxicity Test of 8 Fungicides Against Trichothecium roseum Causing Mango Fruit Rot

The toxicities of 8 fungicides against Trichothecium roseum causing mango fruit rot were tested by mycelial growth rate method. The results showed that the 8 fungicides could inhibit the pathogen of the mango fruit rot efficiently. All the tested fungicides except flusilazole could be used to control the disease caused by T. roseum. The toxicity result was analyzed according to the EC50 value,EC75 value and slope coefficient of toxicity regression equation. The toxicity of carbendazim was the highest against T. roseum with the EC50 value of 1. 30 mg·L-1 and EC75 value of 3. 09 mg·L-1 ,followed by prochloraz-manganese chloride complex,tebuconazole, myclobutanil,kresoxim-methyl. mancozeb and chlorothalonil had the lowest toxicity.
