What pesticides are used to control vegetable pests?

In fact, in view of this situation, it is more effective to use chemical sprays to remove pests. For example, the aeropamine spray, this type of spray is a spray specifically for vegetable pests, and the use effect is also relatively good. It can be bought in the usual pesticide store, because there are generally this kind of pesticide stores in the countryside, just to prepare these things, in case from time to time there will be farmers who will buy these drugs to ** their own vegetables.

However, when we buy these agricultural drugs, we must remember not to buy some highly toxic pesticides, because the state has expressly banned the consumption of high-concentration pesticides. Because every year, there are accidents such as accidental ingestion of pesticides, resulting in the loss of many people's lives, so we have to pay attention to this aspect. And don't go to some informal pesticide stores to buy these things for good results or to save money, it is very likely that when you use these informal ** products, it will increase your vegetable pests and the possibility of loss is greater.

And after using these pesticides, you should always pay attention to them at home, to remove some bad leaves or pests, because there are some pests that are contagious, if you don't clean up in time, it is likely to infect the next batch of better vegetable seedlings. In addition, if you don't clean it up in time, it will damage your next batch of good vegetable seedlings, so the loss will be even greater, and it will not be worth it, so you still need to work hard and pay attention to it at all times. <>

Finally, it is a common question, if there are elderly people or children in the family, they should always pay attention to the news that these medicines are not easy to touch, or that they can't see them, because there are children who have accidentally ingested pesticides and died. Because there are many children who don't know that this drug is poisonous, and they don't know that it is very dangerous to touch these drugs at will, so they still have to be more careful in this regard, and have to keep an eye on it to avoid any accidents.

At this time, pesticides should be used, and the appropriate pesticides should be selected according to the variety of crops and the types of pests and diseases that appear, and the concentration should also be noted.

First, imidacloprid, second, acetamiprid, third, bifenthroster, fourth, brompronil, fifth, 10% furanfenoylhydrazonitrile suspension, sixth, emamectin.

Thiamethoxam is the most commonly used. This pesticide works very well and is very versatile.

It should be necessary to use some spray pesticides that resist diseases and insects, as well as some pesticides such as wet powder pesticides and uric acid pesticides to control them, mainly according to the different vegetables, so the pesticides will definitely be different.

Growing vegetables really hates this kind of insect, after all, it will affect the growth and appearance of vegetables

Of course, you can also use some yellow boards to trap, which is also a particularly common method. Although pesticide spraying has a quick effect and can solve a large number of problems immediately, many growers will choose to use yellow plates to trap after spraying with pesticides, because these insects are inexhaustible, and they may come again after a week, so it is very appropriate to use yellow plates.

Malathion, pine borer, aphicarb resistance, dimethoate, deltamethrin, methoate, imidacloprid, can also be used.

Answer 1: Agricultural prevention and control in summer and autumn combined pruning, pruning the damaged branches or branches with insects and eggs, and erasing the new shoots that are sporadically pumped during the growing season. 2. Biological control and protection of natural enemies, such as the scarcity of natural enemies in the garden, can also be collected from wheat fields, cotton fields or rape fields ladybugs, aphid flies and lacewings released into tomato fields, to control insects and insects, to achieve the purpose of prevention and control. 3. For pesticide-free control, 100 grams of edible soda ash + in 15 kg of water, shake well, let it fully dissolve, spray it on the leaf where the aphid is located, and try to spray all the leaves.

To prevent missed spraying, spray again the next day, up to three times, and the aphids will die quickly. 4. Pharmaceutical control begins to spray and control in the occurrence period of vegetable aphids, and the agent can be sprayed with 20% matrine wettable powder 2000 times, or 20% pymetrozine wettable powder 4000 times, or 10% enyldimidoxamin wettable powder 2500 times. When spraying, the nozzle should be upward, focusing on the back of the leaves, and spraying the liquid medicine on the melon aphid as much as possible.

The protected area can also be fumigated with 22% dichlorvos smoke, 400-500 grams per mu each time, scattered in 4-5 piles in the shed, ignited by dark fire, and sealed for about 3 hours, which can effectively kill aphids. There are many methods of vegetable aphid control, and aphids can be eliminated well with agricultural control, biological control, pesticide-free control, and pesticide control, and the use effect is relatively significant.

Anti-aphids can be used, this pesticide can effectively control aphids, and can ensure the yield of crops, is not harmful to the human body.

How to control aphids in vegetable seedlings

Rapeseed aphid is the main insect pest of rapeseed, which can occur throughout the growth period, with adult aphids and aphids dense on the back of rape leaves, stems and flowers, stinging and sucking sap, destroying mesophyll and chlorophyll to cause leaf curling and dead seedlings. At the same time, aphids are also important vectors for the transmission of rapeseed virus diseases. If the control is not effective, it will lead to a reduction in rapeseed production.

Control measures: select rapeseed varieties with strong stress resistance and good comprehensive traits, and mix 20 grams of 10% imidacloprid with 500 times of new high-fat film for every 1 kg of rapeseed before sowing to control aphids at the seedling stage.

Sow seeds at the right time. According to the climatic conditions, variety characteristics, and the occurrence of aphids, sow seeds in a timely manner, and spray a new high-fat film 800 times liquid to keep warm and moisture after sowing to prevent soil splintering and improve the seedling emergence rate.

Strengthen field management. In the rape seedling stage, weeds should be removed from the field and nearby, combined with seedlings or transplanting, and aphid plants should be removed. Apply an insecticide once before transplanting.

After transplanting, spray the new high-lipid film to improve plant immunity and shield the olfactory sensing ability of pests. Cultivate the soil in time and cultivate strong seedlings. Reasonable dense planting to improve ventilation and light transmittance.

Heavy application of basal fertilizer, phosphorus and potassium fertilizer can make rapeseed grow robust, the stalk is hard, and the ability of rapeseed to resist disease and stress is enhanced.
