Strengthening the Prevention of Pepper Seedling Diseases in Winter

Planting peppers in winter, the seedling stage is prone to damping-off, bacterial wilt, virus disease, and wilt disease, and prevention and control should be strengthened.

Prevent the selection of plots that have not grown chillies as seedbeds, and sterilize the soil with a dose of 0.5 kg of enemy pine (95% propionics sodium soluble powder) and appropriate amount of water per acre. Before sowing, it was soaked in warm water at 55°C for 10 minutes, and then 0.3% to 0.5% carbendazim was used to prevent fusarium wilt. Rational rotation, adequate basal fertilizer, and more decomposed organic fertilizer, N, P, K application ratio of 5: 2: 6. During the flowering period and the result period, 100 grams of monopotassium phosphate and 60 kg of water were sprayed per acre to increase the disease resistance of the plants.

In the initial stage of treatment, the diseased plant was burned out in a timely manner, and lime powder was disinfected on the diseased point, or 75% of chlorothalonil wettable powder was used to spray the disease on the center of the disease to suppress the spread of the disease. In the early stages of damping off and onset of blight, spray with 75% chlorothalonil WP 600 times or DKS 1000 times. The viral disease is transmitted by aphids and is sprayed with a 3000-fold solution of U.S.A. (25 g/l deltamethrin) or Uranus (25 g/l bifenthrin), with a phytopathogen (1.5%) Alcohol copper sulphate water emulsion) 1000 times or 2% virus A 500 times spray on the ward. To control fusarium wilt, Irrigate with 50% carbendazim WP or 50% thiophanate-methyl WP. The above agents are sprayed once every 7-10 days, and they are continuously controlled twice.

Most of the Fluorine-Containing Phenylamine products are a light yellow oily liquid, relatively high density, insoluble in water. Most of them are used in the manufacturing of pesticides and dye intermediates, small part of them can be used as an analytical reagent. The steam or smoke of fluorine-Containing Phenylamine series is irritated to eyes, mucous membranes and upper respiratory. Vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. And oxidant may react. Decomposition by high fever and emit toxic gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion. Protective measures must be done carefully during product storage. Once the fire occurred, it must be immediately evacuated from air leakage,personnel to a safe area, prohibit access to the contaminated area. Recommended emergency personnel wearing self-contained breathing apparatus and wear chemical protective clothing. In the ambulance personnel to ensure proper safety measures, immediately use foam, carbon dioxide, dry, sandy soil to put out a fire.
