Abstract

The invention discloses a method for preventing and treating bacterial fruit blotch of watermelons, and relates to the technical field of watermelon disease prevention and treatment. The method comprises the following steps that (1), first treatment is carried out, specifically, a botanical pesticide composition and a bactericide are sprayed on leaf surfaces after the disease blotch is found in the watermelon seedling stage or in the middle and later periods of watermelon expansion; (2) secondary treatment is carried out, specifically, a botanical pesticide composition is sprayed on the leaf surfaces after 2-3 days of the first treatment. The botanical pesticide composition is prepared from thymol, carvacrol and menthol, and the mass ratio of the thymol to the carvacrol to the menthol is (8-20) to (4-12) to (1-2). The method for preventing and treating the bacterial fruit blotch of the watermelons has the beneficial effects that the botanical pesticide composition is used as a core and is mixed or combined with the bactericide, the disease blotch is dried up in the seedling stage or middle and later periods of watermelon expansion within 24 hours after the composition is used, the microenvironment humidity of the leaf surfaces and fruit surfaces is reduced, and the propagation of pathogenic bacteria and the prevalence of diseases are quickly blocked.

Description

technical field

[0001] The invention relates to the technical field of watermelon disease prevention and treatment, in particular to a method for preventing and treating bacterial fruit spot of watermelon. Background technique

[0002] Watermelon bacterial fruit spot disease (hereinafter referred to as watermelon fruit spot disease), also known as fruit spot disease, vaginal skin disease, fruit rot, the pathogenic bacteria are bacteria, and the specific classification is still controversial. The disease can spread with the seedlings over a long distance. Once it occurs in the field, it will spread quickly and cause major or even devastating losses to melon farmers.

[0003] The symptoms of watermelon fruit spot disease are: in the early stage of the disease, small water-soaked spots appear on the surface of the watermelon fruit, and then rapidly develop and expand into irregular water-infiltrated large spots, and develop internally. Lesions generally occur on the upper surf...
