Abstract

The present invention relates to a control method for tomato leaf mildew. The control method comprises the following steps of: 1) carrying out ecological management: (1) composting an applied organic fertilizer, and additionally applying a potassium fertilizer by adopting a formula fertilizer application technology so as to improve the disease resistance of plants; (2) applying an HYT microorganism fertilizer to improve the physical and chemical properties of soil, improve the absorption capability of a tomato root system and enhance a disease resisting capability; 2) carrying out agricultural control; 4) carrying out biological control; 5) carrying out physical control; and (6) carrying out chemical control: spraying a 450-550-fold solution of 58% metalaxyl.mancozeb wettable powder and spraying a 550-650-fold solution of 72.2% propamocarb hydrochloride aqueous solution; and carrying out control every 7-10 days, lasting for 2-3 times. With the adoption of the control method, the tomato leaf mildew can be effectively prevented; and meanwhile, measures including the agricultural control, the physical control and the like are taken to carry out comprehensive control, thereby reducing the average morbidity of the tomato leaf mildew, increasing the yield, remarkably improving the grade of tomatoes and obtaining good economic benefits.

Description

technical field [0001] The invention relates to a method for preventing and treating tomato leaf mold, and belongs to the technical field of plant protection. Background technique [0002] Tomato leaf mold can appear on the leaves, stems, flowers, and fruits of tomatoes, but the most common ones are on the leaves. In the early stage, some chlorotic spots appear on the back of the leaves, and later turn into gray or black purple. Regular mold layer, the front of the leaf turns green and turns yellow at the corresponding part, and when it is severe, the leaf often appears shriveled and shriveled. From the sequence of onset, it often spreads upward from the lower part of the plant, and the pathogen can grow and develop at a temperature ranging from 9°C to 34°C, and the optimum temperature for development is 20-25°C. When optimum temperature and humidity are relatively high (relative humidity is more than 80%), only need 10 days to half a month and just can generally fall ill. ...
