Abstract

The invention relates to the application of a compound to the prevention and treatment of plant fungal diseases caused by alternaria alternata and particularly relates to the application of 2-methyl-5-isopropyl phenol to the prevention and treatment of plant fungal disease caused by alternaria alternate, belonging to the technical field of pesticides. An OP-10 type emulsifying agent is added into the 2-methyl-5-isopropyl phenol according to the proportion of 1-45% of the total volume and dissolved by acetone to prepare a 1-80% (w / w) 2-methyl-5-isopropyl phenol solution used for preventing and treating the tomato early blight, cabbage black spot, tobacco brown spot caused by alternaria alternata. The 2-methyl-5-isopropyl phenol has a strong function of inhibiting various pathogenic alternaria alternata and a good effect of inhibiting the plant fungal diseases caused by various pathogenic alternaria alternata, has a high activity and can take effect quickly, thereby being a novel pesticide for preventing and treating the plant fungal diseases caused by the alternaria alternata.
