CATDOLL : CATDOLL: How to eliminate locusts and protect the environment (How to eliminate locusts and protect the environment)

1. What is the most fundamental method to eliminate locusts?

1. In locust-affected areas, high-efficiency and low-toxic agricultural and biological pesticides can be used to protect the predatory natural enemies in the locust area. Or chickens, ducks, geese and other poultry can be raised on the hillside for prevention and control.

2. Reduce the locusts' living areas. Some locust-infested areas are located in low-lying areas. The land can be converted into ponds for raising fish and shrimps, thus greatly reducing the locusts' living areas.

3. Reduce the food source of locusts. Many species of locusts eat corn, wheat, sorghum, rice, millet, etc., but not soybeans, alfalfa, fruit trees, etc. Planting more soybeans, alfalfa, fruit trees and other trees in the areas where locusts occur can effectively prevent and control locusts.

2. What measures can be taken to eliminate locusts and protect the ecological environment?

1. Natural ecological method: introduce natural enemies of locusts to eliminate them, such as frogs and sparrows.

2. Degradable pesticides. Better degradable pesticides can be naturally degraded in about 20 days, with less impact on the environment.

3. Genetically modified crops. Some insect-resistant genetically modified crops have already come out. You can check and see if there is the variety you want to grow.

The most important thing about locusts is to kill them before their eggs hatch, otherwise there will be a locust plague next year.

3. How to control locust plagues?

1. Environmental protection

The occurrence of locust plagues is mainly caused by natural factors, but it is undeniable that there are a considerable number of human factors. Locusts must lay eggs on land with a vegetation coverage rate of less than 50%. If a place is beautiful and has no exposed land, locusts cannot reproduce.

At present, the ecological awareness is not strong in some places. Some simply believe that controlling pollution is the only way to protect the environment. However, they do not attach importance to improving the vegetation, soil and microclimate in locust-friendly areas because there is no visible benefit in the short term.

2. Chemical control

It is recommended to use high-efficiency, low-toxicity, and low-residue counterpart pesticides, such as 5% Scrapir suspension, and spray 20-30 ml per mu with 50-60 kg of water.

You can also sprinkle trichlorfon powder on small bamboos and weeds within 10 days after the locust nymphs emerge from the ground, or use dichlorvos smoke to kill them. After applying the pesticide, you should strengthen monitoring, quickly check the control effect within a week, and apply the pesticide again in time for areas that have been missed or have poor control effect.

You can also use the trapping method: cut the straw into four or five inch long pieces, put it into a liquid prepared with 50 kg of human urine and 0.05-0.1 kg of 50% wettable trichlorfon, immerse it for 8 hours, and scatter it in places where locusts are found on sunny mornings.

At present, the most effective way to kill locusts is to spray pesticides from airplanes. This method has a high insecticide rate and a wide killing range, but it is costly, and the control method based mainly on chemical control can only meet temporary needs and cannot guarantee long-term stability.

3. Natural enemy control

In the long run, to effectively prevent and control locust plagues, we must focus on ecological construction and implement a combination of plant protection, biological protection, resource protection and environmental protection. In particular, we must ensure the diversity of organisms and protect the natural enemies of locusts. According to statistics, there are currently 68 natural enemies of locusts in my country, including birds, amphibians, reptiles, etc., which play an important role in controlling the number of locusts.

4. A new way to eliminate grasshoppers?

method:

1. Chemical control method: Use chemical spray or powder spray for large-area spraying, such as malathion, second-line oil, and ultra-low-volume spray for aircraft ultra-low-volume spraying, and kasik, malathion crude oil, and levofloxacin for ultra-low-volume spraying on the ground.

2. Biological control method: Release chickens, ducks, geese and other poultry in places where locust swarms are present, and eliminate locusts through poultry predation. Microsporidia can also be applied over a large area.
