Embodiment 1

[0046] A kind of comprehensive control method of tomato cotton rot, it is characterized in that, comprises the following steps:

[0047] 1. Soil ecological management:

[0048] (1) Apply Diflon fertilizer for greenhouses. The specific method of using fertilizer for greenhouses is to mix 200ml of fertilizer for greenhouses with 15L of water, mix the fertilizer for greenhouses evenly and spray it on the ground;

[0049] (2) Apply traditional Chinese medicine micro-fertilizer one month before the tomato begins to mature, and the traditional Chinese medicine micro-fertilizer consists of 60 parts of medical stone powder, 5 parts of Ginkgo biloba extract, 7 parts of Artemisia annua extract, and 6 parts of Artemisia argyi extract in parts by weight. , 2 parts of honeysuckle extract, 6 parts of Radix isatidis extract, 3 parts of Baibu extract, and 4 parts of Agrimony extract; the method of using Chinese medicine trace fertilizer: 30g per mu, add 50kg of water and spray on the leaves; ...

Embodiment 2

[0063] Substantially the same as Example 1, the difference is that 300ml of fertilizer for greenhouses is used per mu,

[0064] The prevention and control method of the invention effectively prevents the onset and spread of the tomato cotton rot, and compared with the comparative example, the tomato output is increased by 18%, and the product quality is greatly improved.

Embodiment 3

[0066] Substantially the same as Example 1, the difference is that 400ml of fertilizer for greenhouses is used per mu,

[0067] The prevention and control method of the invention effectively prevents the onset and spread of the tomato cotton rot, and compared with the comparative example, the tomato output is increased by 22%, and the product quality is greatly improved.

Abstract

The present invention relates to a comprehensive control method for tomato pythium rot. The comprehensive conrol method comprises the following steps of: 1, carrying out soil ecological management: (1) applying a Difulai greenhouse type fertilizer, with the use amount of 200-400ml per mu; (2) within one month before tomatoes become ripe, applying a traditional Chinese medicine trace fertilizer, with the use amount of 30-35g per mu; 2, carrying out agricultural control; 3, carrying out biological control; 4, carrying out biological prevention and treatment; 5, carrying out physical control: (1) cleaning plants with serious diseases and diseased residual bodies in time and intensively destroying the plants with serious diseases and diseased residual bodies; and 6, carrying out chemical control: (1) when finding diseased fruits, firstly picking the diseased fruits and then spraying pesticides; alternatively spraying and applying a 500-fold solution of 80% mancozeb wettable powder and a 500-fold solution of 58% metalaxyl mancozeb wettable powder; spraying once every 7 days; and continuously spraying for 3-4 times. By virtue of the comprehensive control method, measures including the soil ecological management, the agricultural control, the biological control, the biological prevention and treatment, the physical control, and the chemical control and the like are adopted, so that the mobility of the tomato pythium rot is greatly reduced, the effect is good, and the yield and quality of tomatoes are improved.

Description

technical field [0001] The invention relates to a comprehensive control method for tomato cotton rot, belonging to the field of tomato pest control. Background technique [0002] Tomato cotton rot is one of the common diseases on tomato, and it occurs in all vegetable areas, both in open field cultivation and protected cultivation. The disease is severe in years with a lot of rain during the growing period. Severe disease often causes damping-off of seedlings and fruit rot. [0003] It mainly attacks fruits, especially those close to the ground, but it can also cause damping-off during the seedling stage. The fruit is infected with water-soaked yellow-brown or brown spots, which rapidly expand and soften, causing the whole fruit to rot. The appearance of the damaged fruit does not change color, and sometimes the peel is broken. A large number of white mold layers are densely grown on the surface of the diseased part. [0004] The disease is caused by the infection of the...
