After the beginning of summer, there is a high incidence of crop diseases and pests, how to carry ou

First, rice pests. May is the damage period of the first generation of two borers, three borers and rice bracts in early rice and early middle rice. All kinds of borers do not come out of the ants for a few days, it will harm the heart and leaves of rice seedlings, causing rice to wither.

After the borer emerges from the ant, the physiological larval stage,, Ring Disease,The fruit began to be infected about 10 days after flowering, and the infection amount was closely related to the rainfall, and timely spraying before bagging was the key to reduce the infection rate and the later fruit rot rate.

Prevention and control methods: spray imidacloprid from the emergence of seedlings, spray cyhalothrin, thrips emulsifiable concentrate, avermectin, etc. after the leaves, and apply organic fertilizer, oil dry or fire soil with chemical fertilizer, rooting fungus fertilizer, and toxin together. Seedlings from insecticides + algae + regulators + Baitai or Shigao, after the planting site is finished, directly plant garlic or leeks, after the young leaves grow, use human urine to match the appropriate amount of water to drench garlic or leeks, sprinkle plant ash to control pests and diseases, or soak plant ash with water, and spray leaves with appropriate water to control pests and diseases.

Of course, there are: for example, sweet and sour solution, butter plate trapping insects, etc. We need to thank those farmers who deal with the land and crops all day long, in the actual planting process of agriculture, they have found and accumulated a lot of agricultural planting management tips for us, take 5 kg of peach trees, 100 grams of lime, soak them in 3 times the water for 5 hours, squeeze the peach leaves dry and remove the slag, add 10 kg of water per kilogram, spray, can control cotton aphid, corn borer, rice insects.

You can also boil peach leaves with water and filter them for spraying.

Before planting, the soil is deeply turned to improve air permeability, and at the same time, comprehensive disinfection is carried out to eliminate possible pathogenic bacteria. In the process of management, scientific planting according to the types and characteristics of vegetables Thank you for the invitation. This question is more general.

Different vegetables, different seasons, different environments, different pest control measures are different. It's hard to be specific. However, one thing is the same, prevention is the main thing, and treatment is the secondary.

After summer, you should add more water to the soil, and you can also fertilize properly, cut off some yellow leaves, and let direct sunlight for pest control.

Of course, there should be ventilation every day, and every day in the afternoon be sure to touch some insect repellent medicine, so that you can prevent insect infestation.

Crop pest control should be done well in advance. It can be sprayed with pest drugs, or some pest-resistant animals can be raised for biological control.

Hello dear! Autumn and winter are the best seasons for pest control. After autumn, most crops are gradually harvested, leaving weeds and straw in the fields.

During this period, it will be more difficult for underground pests to obtain nutrients, water and food, and as the temperature of Qi Nian Brother decreases, the pest will also begin to enter the hibernation period. After the harvest of crops in autumn and winter, there is no need to consider the hidden danger of pesticide damage caused by the attack of the medicine hole, and it is better to grasp the timely spraying of drugs during this period.

Now the temperature is slowly dropping, which indicates that winter is coming. At this time, various diseases and pests are basically not very active and have little mobility. If winter control measures are effective, the occurrence and degree of pests and diseases in the coming year will be greatly reduced, achieving twice the result with half the effort.

Therefore, winter is a good time to control pests.

Many pathogens (bacteria) or overwintering eggs of flower seedling pests and diseases overwinter in litter or weeds in nurseries. Therefore, in winter, the garbage and weeds in the nursery should be completely removed and destroyed to improve hygienic conditions, which can greatly reduce the risk of various pests and diseases. Combined with winter pruning, the focus is on cutting off pests and diseases, such as eggs on flowering trees such as roses and moonflowers, and scale insects on poplars, willows and flowering shrubs.

The branches and leaves pruned by pests and diseases should be cleaned up in time and transported out of the nursery for centralized destruction.

Winter ploughing and deep ploughing can make the larvae, pupae and eggs of underground pests lurking in the soil such as grubs, ground tigers, mole crickets, etc., suffer mechanical damage, and after being exposed to the surface, they can be pecked by natural enemies such as birds, and if necessary, they can also be manually killed. Whitening of branches can not only effectively prevent the frost damage of flowers and trees in winter, improve the disease resistance of flowers and trees, but also destroy the wintering place of diseases and insects, and play the dual role of both frost prevention and insecticideIn particular, it is better to kill mites and scales that overwinter in the bark. Special attention should be paid to the fact that quicklime must be fully dissolved, otherwise it will easily cause burns when applied to the branches of flowers and trees.

In winter, all kinds of pests and diseases are mostly dormantFor those pests and diseases that are difficult to control during the season, winter medicine can be used to control them. If scale insects can be controlled by spraying agents that specifically kill scale insects, then spraying fungicidal products in late winter will have a good effect on the prevention and control of pear rust, rose black spot and other diseases.

Buy some pesticides and use drugs to control pests and diseases.

You can take a plastic bag to cover the plant, or you can spray medicine, a lot.

It can be properly insulated**, and it can also be a drug**.

Buy some ** bug medicine. Take it regularly.

Sprinkle lime on the surface or water the frozen dead insects.

Some insecticides can be used, and they can be purchased online, which is very convenient to use.

Spraying is generally the main method.
