Green pepper is one of the main varieties of winter season's counter-season vegetable cultivation. It must be controlled in advance for damping-off, blight, viral disease and blight of green pepper. Control methods 1. Cultivate strong seedlings. Select wasteland or paddy fields as breeding grounds, and disinfect the soil with 0.5 kg of enemy pine per acre. Before sowing, the seeds were soaked in warm water at 55°C for 10 minutes and then soaked in 50% carbendazim 0.3% to 0.5% wettable powder. 2. Cultivation management. Rational rotation, full base fertilizer, apply more organic fertilizer, nitrogen, phosphorus, potassium fertilizer application ratio of 1:0.4:1.2. Starting from the ditch, reasonable close planting, the flowering period, the results of each spraying a single potassium dihydrogen phosphate, per acre of potassium dihydrogen phosphate 100 grams of water spray 60 kg, can improve the plant's disease resistance. 3. Spray control. Once the above diseases occur, the diseased plants should be removed and burned in time, and lime powder must be disinfected at the diseased points, or sprayed with 75% chlorothalonil 1000 times solution to suppress the spread of the disease. Appropriate chemicals should be used to prevent and control: 1 damping-off and blight in the early stages of the disease with 75% chlorothalonil 600 times or 95% of the enemy to spray 1000 times enemies. 2Virus disease is transmitted by susceptible locusts, so the locusts can be killed by 2.5% enemy kill or Uranus 3000 times solution or vegetable and fruit phosphorus 1500 times, spraying disease with 1000 times solution of plant disease or 2% virus a500 times. Area. 3 Wilt pathogens can overwinter in soil or on seeds. Therefore, we must use resistant varieties, can also use 50% carbendazim or 50% thiophanate-methyl 500 times soaking root. The above liquid is sprayed once every 7 to 10 days and sprayed twice. (Source: Sichuan Agricultural Economy Network)
