Can cotton aphids be treated by spraying?

OK. Because the aphids disappeared after the pesticide was applied to my cotton, I thought that it could be dealt with by spraying pesticides.

No. Because the quality of cotton will be greatly damaged by spraying, it cannot be treated by spraying.

In this way, you can reach a very good solution, and you will make your crops better and better.

After the cotton plant produces pesticide damage, the specific manifestations are that the leaves are in the shape of chicken paws, and the leaves shrink and thicken. The top stem is slightly bent, the growth of the bud eye is stunted, and there are many fresh shoots coming out of the petioles. A lot of flower bones fall off, if not immediately made up for the inability to sit on the peach for a long time, resulting in low and poor quality.

1.The equipment is not clean because of the rapid development trend of herbicides in recent years, the types are increasing day by day, and the scope of application is expanding rapidly. In particular, the area where herbicides are used in wheat fields has expanded.

However, some farmers only have a sprayer, and after spraying herbicide for the wheat field, they do not clean the equipment immediately, and use the equipment with herbicide residue to spray the cotton wool, resulting in pesticide damage.

2.When the vast majority of cotton farmers use chemical fertilizers to prevent diseases, they cannot apply the concentration value marked in the manual, and increase the concentration value freely, resulting in pesticide damage.

1.After spraying the herbicide in the wheat field, the sprayer should be cleaned with clean water first, and the sprayer should be cleaned several times before applying other chemical fertilizers to prevent pesticide damage caused by herbicide residues.

2.If the sprinkling cleaning method is found immediately, immediately spray water to carry out cleaning, spray 1 time a day sooner or later, spray for 3 4 days, which can effectively manipulate the development trend of drug damage and reduce the damage caused by drug damage.

3.Growth hormone reduction method sprays hormone drugs green plant naphthalene acetic acid immediately after the drug damage is produced to reduce the damage and promote growth and development, and the general spray concentration value is 40mg ml saturated solution.

4.After the pesticide damage caused by the fertilization and seedling promotion method, the growth and development of the stem is hindered, and nutrients should be given immediately. First, the leaves can be sprayed with fertilizer, which can be topped with drought-tolerant growth and development nutrients to quickly fill nutrients; The second is fertilization of the soil layer, which can be topdressed with 5 6kg of urea solution per mu to promote the normal growth and development of the stem and alleviate the level of pesticide damage.

Hengkai. 5.The soil cultivation and soil turning method is carried out to eliminate soil compaction, improve the air permeability of the soil layer, promote the activity content of beneficial microbial strains, accelerate the dissolution of nutrients in the soil layer, improve the absorption of nutrients and water by the rhizome, so that the stem can resume growth and development as soon as possible, and reduce the damage caused by pesticide damage.

Summary. Hello dear. 70% of thiamethoxam can kill cauliflower aphids.

thiamethoxam is a neonicotinoid insecticide, which has the characteristics of wide insecticidal spectrum, high activity, strong conductivity and low toxicity, which can be sprayed on the foliar surface, and can also be treated with seeds, roots and soil, and can be quickly absorbed by the roots, stems and leaves of the plant after application, and conducted to all parts of the plant to achieve the purpose of rapid insecticide.

Can thiamethoxam 70% kill cauliflower aphids.

Hello dear. 70% of thiamethoxam can kill cauliflower aphids. Thioxam or pyroxam is a neonicotinoid insecticide, which has the characteristics of wide insecticidal spectrum, high activity, strong conductivity and low toxicity, which can be sprayed on the foliar surface, but also for seed treatment, root irrigation and soil treatment, and can be quickly absorbed by the roots, stems and leaves of the Youwu plant after application, and conducts to all parts of the plant to achieve the purpose of rapid insecticide.

You don't need to add any pesticides, do you?

Dear, you don't need to add any pesticides.

The use of thiazis hypervasine 70% seed treatment dispersible powder is used for seed dressing to control aphids, planthoppers, leafhoppers, fruit flies, thrips, rice gall mosquitoes, green blind bugs, weevils, needleworms, leaf miners, etc. Dosage per 100 kg of seeds (grams): beet 43-86, rape 300-600, seed dressing method:

The dosage of each 100 kg of seeds is thrown into the kilogram and ridge water, dissolved and stirred well, and then mixed with the seeds.
