Chemical pesticides have the advantages of quick effect, high control effect and convenient use, and have been used as a "magic weapon" for controlling pests and diseases for many years. However, with the passage of time, the resistance of pests and diseases has been continuously enhanced, the control effect has been declining, and the ecological environment has been continuously damaged. China has accumulated a lot of good experience in the fight against crop diseases and insect pests: the combination of chemical pesticides and fertilizers can not only control a variety of pests and diseases of crops, but also have the effect of increasing production and saving the environment and protecting the environment. Generally, it can save 30%~60% of pesticides than pesticides used alone, save 2~3 labors per acre, and reduce the cost of mu by 50~90 yuan. Trichlorfon plus grass ash and wood ash is a kind of high-quality farmyard manure, and has the function of controlling crop diseases and insect pests. After using 50 kg of sieved hay ash per acre and mixing with 2.5% trichlorfon powder 2 kg, the effect of controlling cotton voltain is as high as 98%, and the control is controlled once every 7 days, which can control the hazard hazard. Pesticides can save 50%. Because of trichlorfon and dichlorvos, it is sensitive to sorghum, corn, soybean and other crops, and is susceptible to phytotoxicity. Do not use this type of crop. Lego and vinegar vinegar are rich in nutrients, and the organic acids contained in it have a good killing effect on some viruses, germs and sucking pests. The sugars, amino acids and the like contained in the crops are nutrients required for the crops and have a certain yield increasing effect. Because vinegar can soften the body wall of pests and enhance the penetration of liquid, it can improve the control effect by mixing with acidic pesticides. Mix vinegar with 40% dimethoate and water in a ratio of 1:1:1: 1000, spray 50~70 kg per acre to control aphids, red spiders, thrips, leaf miners, wheat leaf bees, etc. A variety of pests, insecticide up to 90%, than the use of dimethoate to save pesticides 40%, an increase of about 5%. Urea preparation (1) Urea and dichlorvos: use 80% dichlorvos 25 ml per acre, 0.5 kg urea, add 50 kg of water and mix evenly, spray once every 7 days, chew mouthparts on vegetables, fruit trees, grain and other crops. The control effect of the pests of the sucking mouth device is 95%, which can save about 50% of pesticides and increase the yield of crops by more than 6%. (2) Urea and Dimethoate: After mixing 40% of Lego emulsifiable concentrate, 50 ml of urea, 0.5 kg of urea and 60 kg of water per acre, it can control a variety of pests such as aphids, thrips and leaf miners, and has obvious effects on increasing yield. . Dimethoate plus diammonium phosphate 50 kg per acre, add 0.5 kg of diammonium phosphate, 40% omethoate 30 ml, mix and even control the red spider, aphid, thrips, cotton bollworm and other pests on the grain cotton crop, The effect is over 90%, once a week, and used continuously for 3 times, which not only effectively controls pests, but also increases crop yield by 10%. The oxalic acid secreted by the potassium phosphate dilution solution for cotton plants can attract cotton bollworms to lay eggs and their fear of phosphorus habits. During the spawning of cotton bollworms, use 2% superphosphate fertilizer solution or 0.3% potassium dihydrogen phosphate solution. Spray the top of the quasi-cotton plant and spray 50-70 kg per acre. And to do 10 sprays per line, leaving 3 rows without spraying, driving cotton bollworms to concentrate on the unsprayed cotton plants to lay eggs. Then use anti-egg pesticides such as sulphate and phosphorus, and focus on controlling cotton plants that have not been sprayed with phosphate fertilizer, which can save more than 50% of pesticides and labor. The sprayed phosphorus can chemically react with the oxalic acid secreted by the cotton plant to form calcium oxalate, which loses the ability to induce the cotton bollworm; the phosphorus can harden the eggshell of the cotton bollworm, and the larva can not hatch and die; phosphorus It also prevents premature aging of cotton, promotes maturity, increases yield and improves fiber quality. Although the above-mentioned preparations are not as fast as insecticides, they are popular because they have increased yield, cost, and environmental protection, and are not easily resistant to chemicals. The preparation should be used with the product and should not be stored. The spray should be meticulous and thoughtful, so that the whole plant adheres to the liquid. And strict preparation methods, the scope of use, dosage, concentration, to avoid the occurrence of phytotoxicity, to ensure the control effect.
