What is the specific medicine for pepper bacterial wilt?

1. Drug control: Dip the roots with 100- 150 times chlorothalonil solution before planting, and irrigate the roots with 300 times Wang Di+150-300 times chlorothalonil solution +600 times warfarin solution1-at slow seedling stage and seedling stage. 2. Agricultural control: cultivate strong seedlings, control the amount of nitrogen fertilizer, rotate with Gramineae crops for 4-5 years, pull out diseased plants in time, and sprinkle lime powder on diseased spots.

First, the specific drug of pepper bacterial wilt

1, drug control

(1) Dip the roots with chlorothalonil with the concentration of 100- 150 times before planting.

(2) At the slow seedling stage and seedling stage, root irrigation was performed with 300 times of Diliwang+150-300 times of Ralstonia solanacearum +600 times of Lofty Tree Solution, and continuous irrigation was performed with 1-2 times.

(3) Spraying with 600 times of warfarin+150-300 times of chlorothalonil solution for 2-6 times.

(4) At the early stage of the disease, the roots were irrigated with 4000-fold solution of 72% agricultural streptomycin (or 50% zineb wettable powder 1000-fold solution), and each plant was irrigated with 0.5 liter, once every 10 day, for 3-4 times in total.

(5) Use 1000- 1500 times of garlic oil and 90- 150 times of chloropicrin to spray the roots. Spray 1 time 1 time every day for 3 consecutive times; Root irrigation 1 time every 2-3 days, and continuous irrigation for 2-3 times.

2. Agricultural control

(1) Choose the higher ground as the planting area, cultivate strong seedlings, balance fertilization and control the amount of nitrogen fertilizer.

(2) Reasonable rotation, with corn, wheat, rice and other gramineous crops for 4-5 years.

(3) Unplug the diseased plants and sprinkle lime powder on the diseased points.

2. What caused pepper bacterial wilt?

1. Plot where solanaceae crops (eggplant, potato, pepper, tomato, etc.) are planted. ) are prone to illness.

2. The soil is acidic, the drainage is not smooth, the terrain is low, and the disease is serious.

3. The stem base of the plant is eaten by underground pests (such as ground tigers), and bacteria invade the interior from the wound, and it will get sick after a while.

4. The temperature is high and the humidity is high, so it is easy to get sick. The disease is easy to spread when the weather suddenly turns fine after a long period of rain and the ground temperature rises rapidly.

5. Pepper is planted all the year round, but it is not supplemented with enough potassium fertilizer, which leads to the decline of disease resistance of pepper due to potassium deficiency, so it is prone to this disease.
