Vegetable disease, pest harmless treatment technology

Vegetable disease, pest harmless treatment technology

Humans have "drugs" that use drugs and drugs, as do insects. The biggest "poison" in vegetables is aphids. In spring, the locust first came out to feed on vegetables, and the maggots that took leaf juice on virus-vegetable vegetable plants were brought wherever they took the virus. Therefore, severely punishing maggots not only has the effect of protecting vegetables from pests, but also prevents aphids from transmitting viral diseases. There are many ways to punish locusts. They use less money, use less drugs, and less pollute the environment. There are no residual poisons to the product: (1) The silver-grey film drives locusts: the locusts avoid silver-gray. The vegetable growers can lay a 0.4-meter-wide silver-gray film around the vegetable seedlings, and drive silver-gray film strips on the seedbed to drive the locusts to prevent them from approaching vegetable seedlings. (b) aluminum silver gray reflective mesh mesh avoidance: in the nursery bed to take a transparent film covered arch shed, shed four walls with aluminum silver gray reflective film mesh to block the silver-gray reflective repellent aphids. (C) Yellow traps: Locusts are particularly fond of yellow, and vegetable growers can use a yellow glass, film or wood board, plastic plate to make a 35-50 cm square decoy swatch, coated with a layer of engine oil, butter or vaseline, mounting In the field, the locusts were tempted to fly and were stuck in color plates and died. (D) killing of self-made harmless pesticides 1, tobacco lime agent: take 0.5 kg of tobacco, soaked in water for 24 hours plus 50 kg of water diluted, plus 0.5 kg of quicklime powder and stir, filter with a filter spray. 2, cotton oil soap agent: take cotton soap 1 minute, add water 60-80 times melted and sprayed. 3, pumpkin leaf preparation: pick the pumpkin leaves add a small amount of water smashed, with gauze squeezed the original liquid, when used, add water 1.5 times and add a small amount of detergent to stir the spray. 4. Garlic preparation: Garlic cloves into garlic, 1 point of garlic plus one minute vinegar, plus 50 times of water soak for 10-12 hours, and use 10 times of water spray for the filter solution. (5) Deterrence of special pharmaceuticals: "Anti-influx" is a moderately toxic acaricide. It is not only highly efficient but also has a short residue period and does not harm natural enemies and bees. The drug concentration is 3000 times. In addition, 10% imidacloprid wettable powder 40-70 g water 40-60 kg can also be sprayed. The use of special chemical pesticides to eliminate aphids should pay attention to the safety interval of the time to market to prevent pesticide residues.
