Dear friends, everyone, the Century Pesticide Network Xiaobian has come to give you a general approach to the prevention and control of plant diseases and insect pests. Doing a good job in the prevention and control of pests and diseases is a very important part of the planting process and is of great significance for improving production. Let's take a look at it with Xiaobian!
Underground pests generally include root mites, tigers, crickets, crickets, and golden worms. The most important crops are peanuts, cotton, soybeans, corn, wheat, vegetables, and fruit trees. The pesticides commonly used to control underground pests include imidacloprid and methyl. Isophosphorus granules, phoxim particles, phoxim emulsifiable concentrate, 3911, phorate, deltamethrin emulsion, trichlorfon, and the like.
Chemical dressing
Using 3911, phorate, phoxim, etc., the seed dressing amount is 0.1% to 0.3% of the seed component. Specifically, it is 60% phorate, 40% methyl isoflavin is 0.2%, 50% phoxim is 0.1%, and 20% methyl isoflavin emulsifiable concentrate is 0.3%. Dissolve the agent with about 3 kg of water, then spray it evenly onto the seeds, mix well, and dry until semi-dried. Seed dressing at 0.01% to 0.1% of the seed content. This method can also be used for seed dressing of vegetable crops.
Poisonous soil
Use 40% lesbian to control underground pests, 15 ~ 20 kg per 150 ml of fine sand, you can also use 75% phoxim or 20% pyrethroid emulsion, etc., do not separate from the 1:2000 share into toxic soil, 20 to 25 kilograms per acre, applied to the crop.
Poison bait
Use 90% crystal trichlorfon 30 times solution, stir-fry the cornmeal, add green leaves, and sprinkle on the ground around the crop at dusk. Or chop the fresh grass or vegetables, use 2-100kg of 50% phoxim and water to spray 2-2.5kg, spray on 1000kg of grass, place the field in the dusk dividend, and trap the tiger. Each acre is mixed with frying (bean cake, wheat bran, sorghum, corn, etc.) 1.5-2 kg, or 50% phoxim 50 g, or 40% methyl isothiophos 50 g plus water, mix well, at dusk Sprinkle around the rhizosphere of the field crops, the effectiveness of the tigers and cockroaches can reach 80-90%.
Spray control
Use 50% phoxim 800 times solution, spray the ground with the ridge, use 25% bromomethrin 30-40 liters and add water 75 kg. Spray after the sunset, the stems and leaves should be sprayed and sprayed 1 or 2 times. Can be used to kill the tiger.
Pharmacy treatment soil
Use 50% phoxim emulsifiable concentrate 200-250 grams per acre, add water 10 times spray on 25 ~ 30 kilograms of fine soil and mix well to make toxic soil, apply ridges, then shallow sputum.
