How to prevent and reduce cotton pests?

I think that in terms of planting, we must choose fertile soil, and then water it more and fertilize it more, and spray it with pesticide in advance, so that we can reduce the damage.

Some pesticides can be sprayed in advance. This method works very well and is also a common method used by farmers.

It is best to plant cotton and other crops separately to prevent infectious pests and diseases. If it is found that cotton is sick, it should be used in time to use plant-specific insecticides, evenly sprayed on plant leaves, and should not be watered during the medication, otherwise there will be no effect.

It is necessary to increase cotton production and improve cotton quality. In order for cotton to become better, pests and diseases must be prevented during the planting process. Now we will learn how to deal with pests and diseases encountered in cotton farming.

Cotton wilt is very common. No matter in the first cotton planting, wilt will occur. In addition, cotton wilt can reduce the yield and quality of cotton, so it is necessary to prevent the occurrence of wilt.

Basically, the wilt of cotton is formed during the seedling period of cotton. Generally, the leaves turn yellow first and then black, which will cause the leaves to wither and die. After the cotton is harvested, all the cotton branches and leaves can be buried or burned in winter, so that the cotton can be alleviated in the second year, and carbendazim should be sprayed when cotton wilt occurs.

Cotton Verticillium wilt is a yellow spot that appears on the leaves and then spreads from the leaves to the roots and grows, causing the leaves to fall off and die. Basically, mancozeb needs to be sprayed to treat Verticillium wilt. If you want to prevent Verticillium wilt, you can plant other plants for another year in the second year, and then plant cotton, which will reduce the disease.

Sow seeds on demand, generally 4 seeds per hole; Strip seeding, generally 50 grains per square meter; Seedling transplanting, 2 grains per hole. In cotton farming, we should choose more benign soils. However, in many parts of our country, it is difficult to find enough benign soil.

In this case, we had to choose saline land for planting. Its sowing rate is different from that of general soil. In order to ensure the yield, it is generally necessary to sow about 10% more.

Basically, cotton aphid is the sound of cotton. Since this kind of aphid basically eats cotton leaves, the leaves curl and die. It is better to spray insecticides.

Cotton is also easy to breed cotton bollworm, which is mainly found on cotton flowers and pears, and falls off at night, which has a great impact on cotton quality. Therefore, spraying with insecticides to treat cotton bollworm is necessary. Also, cotton aphids are born during the growth of cotton.

Cotton aphid needs to be sprayed with imidacloprid wettable powder. Chlorpyrifos solution and new high-lipid membrane solution can control cotton aphid, and it is also easy to breed cotton spider mites, which basically appear in the middle of cotton growth. This bug likes high temperatures, so the higher the temperature, the brighter it is, and the faster it will reproduce.

It is the best time to reproduce. At this time, the spraying of the drug** is very thorough, and the use of mite removal EC and the new high-lipid membrane solution is very effective.

In cotton cultivation, it is necessary to provide a suitable soil environment, select excellent seeds, and ensure a scientific selection process, so as to ensure the final increase in yield. When selecting seeds, be sure to buy them from regular manufacturers, and carefully check the various numbers on the outer packaging to ensure that you can buy high-quality seeds. In this process, we should not choose inferior seeds for the sake of cost savings.

In addition, when selecting seeds, it is necessary to fully investigate and analyze the local ecological environment and select the most suitable seeds. When cotton is grown, it is necessary to effectively control its sowing amount.

Regular fertilization can also ensure resistance to some viruses, and most importantly, when planting cotton, it must be guaranteed to be exposed to sunlight for a long time.

Pesticides. Because after my cotton is sprayed with pesticides, there are few pests and diseases, and the yield is also high, so I should apply pesticides to the cotton.

There are many insect pests in cotton, so cotton should be disinfected, and then insecticides should be sprayed on cotton in a large area. In this way, the cotton insect infestation can be avoided, and then the yield can be increased and disease resistance.
