In order to reduce the occurrence of pests and diseases in growing vegetables, certain precautions should be taken before sowing. For pathogenic sources that overwinter in the soil, such as sclerotinia, 70% of the enemy can be used to disinfect the soil with 800-1000 times of solution, or 25% of erlotine 800-900 times; the pathogenic source of the seed should be before sowing. The seeds were disinfected with 80% zeocin, or 75% chlorothalonil, or 50% thiram, and the dose was 0.3-0.4% of the seed weight to kill the pathogen attached to the seed surface. The chemical control techniques for the various pests and diseases during growth are as follows: Downy mildew can be controlled with 68.75% DuPont EPC 1000-1200, or 52.25% Dupont, 2000X liquid, or 72% DuPont Kelu 600X liquid exchange spray. When the disease is severe, 72% DuPont Ke Lu 600-800 times liquid and 52.2% DuPont fast net 2000-2500 times liquid can be mixed and used. In the early stage of onset of soft rot, 70% DTM can be used for 400 times, or 50% for DSS 600-700 times, or 14% for ROOT 300-400 times, or 40% for 500-600 times for methotrexate ( Crops sensitive to copper should be used with caution, or 72% for agricultural streptomycin, or neomycin with 3000-4000 times, or 57.6% for 1000-1500 times, or 70% for 400- 500 times liquid, sprayed on the ground to control the petioles and stem base. Virus disease cures aphids mainly, and can be controlled with antiviral agent No. 1 500-600 times solution combined with 20% virus A, or virus K600 times solution, or 5% sputum poisonous solution 200-300 times. Sclerotinia can be used 70% thiophanate-methyl 600-800 times, or 50% acetaminophen 1500 times, or 50% fast-king 1500 times, or 50% carbendazim 500-600 times, or green 600 times milk copper prevention and treatment. After the emergence of vegetables, the locusts sprayed once every 6-7 days after the emergence of the vegetables, and used 10% imidacloprid 1500-2000 times, or 1500 times, or 1000 times, or 1000 times, or 20%. Fortune 4000-5000 times liquid and other prevention. The cabbage caterpillar and diamondback moth can use 600 units of BT WP, 60-75 grams of water, 30-40 kg of water, or 2.5% of vegetables, 1000-1500 times of liquid, and 52.25% of farmland's milk of 1000-1500 times, or 1.8%. Insect gram 2000-3000 times, or 5% rigid 1500-2000 times, or 10% divided by 1000-1500 times, or Po Road 1000-1500 times, or 1.8% abamectin 2000- 3000 times liquid, or 15% DuPont hits 3000-4000 times liquid prevention. Locust leaf aphid and yellow stripe armor can be controlled by 40% Gaosiben or 48% Lactose 1000-1500 times liquid, or 2.5% agricultural dilute 1500 times liquid.
