The large-scale heavy rainfall process since the beginning of Mei has caused the water level in Jiande City to rise and local flash floods. Large areas of field water and some crops are flooded, which affects the normal growth of crops and causes serious losses to production. In order to strengthen self-rescue after the disaster, and to minimize losses, in view of the actual situation of agricultural production in Jiande City, the following pest control opinions were issued. kaiping aida sanitary ware technology co.,ltd , https://www.kpaidafaucets-jm.com
1. After the flood control of rice pests and diseases, due to flooding or flooding of rice plants, heavy rain and flooding, it is easy to make rice plants form wounds, and the resistance to stress is reduced, and the heavy rain weather is conducive to rice leaf roller The immigration of rice planthoppers is conducive to the damage of rice sheath blight, rice blast and rice bacterial diseases. Therefore, all localities should attach great importance to it. According to the current rice growth period and the occurrence of pests and diseases, the rice pests and diseases will be effectively done after heavy rain. Prevention work.
Prevention opinions:
Sheath blight: 5% Jinggangmycin water 200 ml / mu, 30% benzyl propionazole EC 20 g / mu, 37.5 kg water spray mist.
Rice blast: Rice blast is a typical climatic disease. In the early stage of the disease, 20% tricycloazole wettable powder 100 g/mu, 40% rice glutinous WP 75 g/mu, 75% sputum·pentazole Alcohol water dispersible granules 10 g / mu, with water spray 37.5 kg spray control.
Bacterial diseases of rice (strip disease, bacterial blight and bacterial brown streak): For flooded paddy fields or paddy fields, they should be treated once and immediately after heavy rain. For uninundated paddy fields or paddy fields, use the drug at the beginning of the disease. Use 20% thiabend copper wettable powder 100 ml/mu or 20% leaf carbazole (thiazolazole) wettable powder 100 g/mu. 37.5 kg of fine spray with acreage of water, against the already-occurring field, after 5 to 7 days after the first use of the drug, once again.
Rice planthopper, rice locust horse: 70% imidacloprid water dispersible granules 6 ~ 8 grams, 25% pymetrozine wettable powder 30 g / acre, with water 37.5 kg spray control.
Rice leaf roller: The agent can choose 20% chlorantraniliprole suspension 10 ml / acre, or 20% Avi chlorpyrifos EC 80-100 ml, 20% Avi · chlorpyrifos EC 80, etc., water 37.5 Kilograms were sprayed in the evening.
Second, vegetable plant protection technology 1, clean up the ravine, remove stagnant water After the flood recedes, it is necessary to quickly ditch, remove underground water, and promote root growth. It is necessary to loosen the dough in time to promote the growth of vegetables. For the seriously affected vegetable fields, the vegetables that have died in the roots should be cleaned up in time, and 25 to 30 kilograms of lime should be applied to the soil for fine soil preparation, re-sowing vegetables or replanting Other cash crops.
2. Understand the disaster situation, and classify and guide some vegetables such as eggplant, pepper, melon and other vegetables that are more heavily absorbed but still have absorption capacity. The crops can be shaved by short-cutting the branches and leaves or using a sunshade net to prevent the sag. Clear exposure to the sun, reduce transpiration, prevent physiological water loss caused by wilting; for other melon vegetables, cut off some yellow leaves, rotten leaves, old leaves, appropriate cultivating, cultivating soil, pressing vines, promoting root development, restoring plant growth; Classes and leafy vegetables can be rinsed with water spray cans, and the sludge attached to the leaves can be rinsed clean.
3. Strengthening the management of fertilizer and water, restoring the growth of vegetable seedlings After the flooding of vegetable fields, nutrients are easily lost. Therefore, nitrogen, phosphorus, potassium fertilizer and other compound micro-fertilizers should be replenished in time. In fertilization, attention should be paid not to overweight and excess. Otherwise, it is easy to cause fertilizer. Harm, so fertilization should be appropriate. At the same time, it must be combined with cultivating While doing a good job of soil fertilization, it can be used for top dressing.
4, after the arrangement, grab the time to plant the field that has been flooded for too long, the vegetable seedlings have died, such as leafy cabbage, melons, eggplants or other vegetables that are not resistant to leaching; Or replanting work. After the flood, it is necessary to apply lime disinfection in time, then clear the land and arrange the sowing period. Priority can be given to arranging the varieties with short growth period, fast growth and high yield to ensure the balanced listing of vegetables and meet the needs of citizens. At the same time, it is necessary to encourage qualified vegetable farmers to use the facility for rapid seedling cultivation and implement facility cultivation to ensure timely listing of vegetables.
5, clearing the use of drugs, comprehensive prevention and control of pests and diseases After flooding, it is easy to cause soft rot, downy mildew, anthracnose, epidemic diseases and various physiological diseases, so after the water is reclaimed, it is necessary to spray insecticides on different varieties and damage levels in time. Fungicide . During the rainy days, it is necessary to rush to clear the medication, choose safe, corrective chemicals to prevent diseases, insects, and rodents, pay attention to the rotation and rational matching of pesticides, and choose 25% pyraclostrobin emulsion 2000 times liquid, 5% sputum 戊Alcohol alcohol dispersible granules 4500 times liquid, 25% azoxystrobin suspension 1500 times liquid to control downy mildew, powdery mildew, anthracnose, etc., 20% thiazolone suspension 500 times solution, 72% agricultural streptomycin Powder-dissolving agent 3000 times liquid and other bacterial diseases, prevention and treatment of physiological diseases can strengthen temperature and water management, timely ventilation and ventilation, nutrient supply should be less nitrogen fertilizer, increase potassium fertilizer, biological fertilizer and humic acid fertilizer, etc. Foliar fertilizer, supplement various nutrients to ensure the normal growth of vegetables; control of Spodoptera litura, beet armyworm, cabbage caterpillar, diamondback moth and other pests can use 15% indoxacarb suspension 3000 times solution, 10% insecticidal nitrile suspension 1000 times solution, 20% flubendiamide hydramide water dispersible granule 2500 times solution, 1 billion PIB/ml silver worm, nuclear polyhedrosis virus suspension agent 800 times solution, 5% chlorantraniliprole suspensor 1500 times solution Etc., 20% acetamiprid soluble powder 5000 can be used to control Bemisia tabaci and aphids In addition, combined with the prevention and control of pests and diseases, root fertilization is carried out to promote crop recovery, such as spraying 0.2-0.3% potassium dihydrogen phosphate solution, 1.8% sodium nitrophenolate solution or orzanolactone. A safe interval for strict application of vegetables, fruits and vegetables.
