Abstract

The invention discloses a method for preventing and treating watermelon blotch. During the growth of watermelon, the apical buds and the excessive branches of the watermelon seedlings are removed in the morning of a sunny day, and the pesticide is sprayed in the afternoon, wherein the pesticide is the 500 to 600-times concentrated 2% aqueous kasugamycin agent or 500-times concentrated 20% rosin acid copper emulsification oil. Compared with the existing method for preventing and treating watermelon blotch, the method has the advantages of short prevention and treatment period, long duration of pesticide effect and reduction of labor intensity, is simple and practical, can not be restricted by the environmental factor and can be used for greatly improvingthe effect of preventing and treating the watermelon blotch due to the adopted technical scheme.

Description

technical field [0001] The invention relates to a method for preventing and treating watermelon fruit spot disease. Background technique [0002] Watermelon bacterial fruit spot is also known as bacterial spot, watermelon flooding disease, fruit rot spot and so on. It is a devastating disease introduced from abroad in recent years. Both seedling and adult plants can be affected. Irregular brown lesions appeared along the midrib of the infected melon seedlings, some of which extended to the edge of the leaves, and looked water-soaked from the back of the leaves. The melon seedlings with seeds infected with bacteria died 1-3 weeks after the onset. When the watermelon fruit is infected, several millimeters in size gray-green to dark green water-soaked spots appear on the upper surface of the fruit, and then rapidly expand into large irregular water-soaked spots, which turn brown or crack, causing the fruit to rot and secrete A slimy amber substance that develops further and ...
