What pesticides are used to control anthrax?

Anthracnose is a common disease during crop growth, which often harms the leaves, flowers, branches and fruits of plants. When it is serious, it will reduce crop production. What pesticides will be used to control anthracnose?

What pesticides are used for anthrax?

Vegetable anthracnose can be diluted by 1500 times liquid spray with Sim Chemical-anthrax special agent, sprayed every 7 days or so, three times in a row. Anthracnose of fruit can be controlled by spray dilution of anthracnose with fresh bromonitrile bacteria. Anthracnose of flowers and trees can be controlled by 500-fold spray of Gabriel source-carbon tetralin.

How to prevent and cure anthrax?

1. Plant anthracnose

Anthracnose is a common plant disease, leaf spot symptoms: leaf spot brown to grayish brown, round or oval to irregular shape, gray-white mildew layer on the surface of the disease when the humidity is high.

The parts of plants attacked by anthrax include leaves, flowers, branches and fruits. On the leaves, chlorotic dots first appeared at the leaf tip and leaf edge, and then expanded into semicircular, round or irregular spots, the diseased tissue was yellowish brown or brown, and small black spots appeared in the later stage, which were fruit bodies, sometimes arranged in a wheel shape, and in case of wet environment, a pile of conidia with white spots and orange was formed. As shown below:

Anthrax incidence conditions: the disease is easy to occur and epidemic in high wet season.

2. prevention and control of anthracnose in garden plants.

(1) in the early stage of the disease, cut off the diseased leaves, burn the withered branches and leaves in the green space in time to prevent expansion; do not plant too densely or indoor flowers should not be placed too densely, do not drench indoor flowers from the top of the plant, and often maintain ventilation and light. Clean the countryside in winter and burn the sick and disabled bodies in time.

(2) adopt scientific fertilization formula and technology, apply sufficient rotten organic fertilizer and increase phosphorus and potassium fertilizer to improve the disease resistance of garden plants.

(3) before the onset of the disease, spray protective agents, such as 80% mancozeb wettable powder (Dasheng) 700 to 800 times, or 1% half-dose Bordeaux solution, or 75% chlorothalonil 500 times solution for prevention and treatment.

(4) spraying 1000 times of 75% methyl topiramate wettable powder and 75% chlorothalonil wettable powder in time during the onset of the disease, once every 10 days, two or three times in a row.

Prevention is an effective means to prevent and control the occurrence of diseases in a large area in the process of crop planting. Adequate daily nutrient supply makes crops in a sufficient nutritional environment, which can also enhance the resistance to common diseases.
