Abstract

The invention provides a formula for preventing and treating tomato stem rot. The formula is a compound liquid composed of 70% by mass of mancozeb wettable powder, 70% by mass of hymexazol wettable powder and 0.01% by mass of brassinolide solvable dilution multiple liquid, and the invention also provides a prevention and treatment method, which comprises the following steps of: dipping roots of tomato seedlings by using the compound liquid before field planting of tomatoes, and performing foliage spray treatment on the tomato seedlings twice by using the compound liquid after field planting.According to the method, tomato seedlings are firstly subjected to root dipping treatment by using a compound solution and then are subjected to field planting; the roots of the tomatoes are effectively protected from being damaged by pathogenic bacteria; the activity of stem rot pathogenic bacteria in the soil is inhibited; leaf surface spraying is carried out twice after field planting, compoundliquid is absorbed by tomato leaf surfaces, protection is formed on the leaf surfaces, invasion of pathogenic bacteria of the stem-based rot is prevented, growth of tomatoes is promoted through brassinolide, resistance of the tomatoes to the pathogenic bacteria is improved, and the prevention and treatment effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of tomato disease prevention and control, and in particular relates to a formula for preventing and treating tomato stalk rot and a method for preventing and controlling it. Background technique [0002] The incidence rate of tomato stalk rot in facility greenhouses is 30% to 40%, often resulting in lack of seedlings and broken ridges, or root rot at the adult plant stage, and plant death. Tomato stem base rot can cause damage at the seedling stage and the adult plant stage, and mainly damages the large seedlings to be planted and the stem base or underground main and lateral roots of tomatoes that have been planted. Seriously affect the economic income of vegetable farmers. At present, the traditional prevention and treatment methods are to use a kind of medicament to prevent and treat, and only after the onset of disease. The control effect is not ideal, often resulting in lack of seedlings and broken ri...
