Aphids are the pests that have the largest amount of production and the longest period of damage in vegetable cultivation. Using pollution-free locust control technology, one can increase the effectiveness of prevention and control, reduce investment, increase economic efficiency; Second, it can reduce pesticide residues, improve the quality of vegetables, and achieve pollution-free production purposes.
First, the use of silver-gray plastic film to avoid aphids on the different colors of the great differences in tropism, silver-gray ticks have a good deterrent effect. Collect some silver-gray food bags or milk powder bags. When used, flip this plastic bag over, making the silver-gray facing outwards, with a colorful picture facing inwards, and inserting it with small wooden sticks into the vegetable fields or seedbeds, which can play a role in repelling vegetables and reducing viruses against various cruciferous vegetables. The role of the hazard.
Second, the yellow plate induces yellow to attract aphids. It can produce yellow cardboard with a size of 1520 cm in production. It is best to apply a layer of No. 10 oil on the cardboard or to cure pesticides commonly used in pesticides, inserting or hanging on vegetables. Between the rows and vegetables are flat. When they saw the yellow cardboard, they had landed on it, and they were promptly replaced after the yellow plate of engine oil had been induced. The drug yellow plate caused the aphid to touch and die. Greatly reduce the double danger of winged worms spreading virus to vegetable fields and directly eating vegetable juices.
III. Plants killing and driving
1. Soak peppers in water for a day and night, filter and spray.
2. Peach leaves soaked in water for a day and night, add a small amount of quicklime filtration and spray.
3. The tobacco is ground to a fine powder and a small amount of quicklime is applied to give good control.
4. The production practice proves that the volatile odor of the leek has a repellent effect on the aphids. If it is planted with other vegetables, it can reduce the density of the aphids and reduce the damage of the aphids to the vegetables.
5. Wash powder The main component of washing powder is sodium dodecyl benzene sulphonate, which has a strong contact effect on maggots. 400-500 times the detergent per acre with a solution of 60-80 kg, and even spray 2 or 3 times, can play a good preventive effect.
6. The natural enemies of the natural enemies of the locust-resistant mites are the seven-star scoops, the different-colored ladybugs, the syrphids, and the pupa fungus, which have an irreplaceable killing effect on the locusts. Therefore, they should be protected and used in production so that the population of locusts can be controlled in a quantity that does not harm them.
