Tomatoes become rotten at maturity, which may be caused by diseases such as soft rot, brown spoilage and anthracnose. Usually, farmers can strengthen scientific management and comprehensively control these three diseases, and at the same time, they can also use pesticide control. Reduce losses.
The following are several measures to control the occurrence of rotten fruit, for the reference of farmers:
1) The management of sunny days causes the normal condition of tomato rotten fruit to be caused by bacterial infection. This is due to the weather influence or time unsuitable for tomato pruning management, which leads to the infection of the bacteria and the speed of disease development. Therefore, plant management of tomatoes is the best time in fine weather. It is best not to organize the tomato plants on rainy days or when the dew is not dry, so that the cut wounds can heal as soon as possible to prevent the invasion of the disease.
2) Elimination of rotten branches According to the Chinese pesticide network , after the tomato is infected with disease, the branches and leaves are very obvious. If brown spots appear on the branches and leaves, this is the primary stage of the infection. It is necessary to remove the diseased leaves and destroy them as soon as possible. The residual leaves and rotten leaves on the ground are burnt or buried. This will prevent the spread of the source.
3) Application of pesticide control In the environment of continuous rain and humidity, tomatoes are very susceptible to infection, and pesticides should be controlled. Soft rot can be sprayed with 70% dikesone 1000 times liquid, spray once every 8-10 days; brown spoilage disease is sprayed with 25% of toxic mycelium 800-1000 times, and once every 7 days, It can be used two or three times in a row; anthracnose can be sprayed with 80% of anthrax damn WP 800 times or 50% of bactericide carbendazim WP 500 times, every 8-10 days, even spray 2 You can do it twice.
