Key points of pest control technology in early flowering period of pepper

At present, it is the initial flowering period of pepper. According to the recent field investigation line, the main diseases and insect pests of peppers are “three diseases and two insects”, namely, pepper disease, virus disease, anthrax and cotton bollworm, tobacco budworm, etc., and should be aimed at early prevention. The principles of governance and pollution-free are scientifically controlled.

1, pepper disease

1 Spray with 5% chlorothalonil dust, 667m21kg of powder every 7 days for 2-3 times.

2 At the beginning of the disease, spray with 64% antiviral WP 500 times, or 58% Leidemier MnZn WP 500 times and 70% EB Phosphorous 500 times.

3 After the discovery of the central disease strain in the middle and late period; with 50% methicone wettable powder 800 times, 72.2% Precike 600-800 times, 64% antitoxic WP 500 times, or 58% Ledomil-Manganese zinc wettable powder 500 times and watering the roots of diseased plants simultaneously.

2, pepper virus disease

1 Early control of locusts. With 10% imidacloprid WP 1500 times, or 25% Aktai water dispersible granules 5000-10000 times, or 40% EC 1000-2000 times spray control.

2 The initial onset is 20% of the virus A wettable powder 400 times, or 1.5% of the diseased emulsion 1000 times, sprayed every 7-10 days, and sprayed 3-4 times;

3, chili anthrax

Spray 2 to 4 times before and after the onset of the disease. Commonly used pesticides include 50% thiophanate 500 to 800 times, 50% carbendazim WP 800 to 1000 times, and 70% mancozeb WP 600 to 800 times. spray.

4, cotton bollworm

When the number of eggs per 100 eggs reaches 20-30 capsules, use 200 times Bt Emulsion, 3000 times avermectin emulsifiable concentrate 1.8%, 5% Sulfuricin EC 2500 times, or 50% phoxim EC. 1000 times spray control.

5, tobacco

When 10% of the pepper seedlings are infested by tobacco budworms, control measures should be taken. 50% phoxim EC, 50% chlorinated pine EC, 40% acephate EC and 80% trichlorfon soluble powder can be used. 1000 times liquid, or 2.5% deltamethrin EC, 20% fenvalerate EC, 2.5% kavancin EC, 5% cypermethrin (Laurel) EC, 10% cypermethrin EC, each 2000 times liquid spray and other methods to control or use adult to trap and kill adults, every 5-10, in the morning to manually capture adults.
