What should I do if there is pesticide damage to crops, and what should I do if pesticides are harme

What should I do if the pesticide is harmed? 1. What are the general causes of pesticide damage? Pesticide is a drug that can prevent crop pests and diseases, crops in the process of growth more or less will appear some pests and diseases, these pests and diseases may not only lead to crop yield, and may even lead to crop failure, so pesticides can solve the adverse effects caused by pests and diseases, but some growers in the process of using pesticides, due to improper operation, may cause pesticide damage, pesticide damage to crops is very large, It will not only affect the healthy growth of crops, but may even lead to the death of crops, in most cases, the appearance of pesticide damage is due to excessive use of pesticides, or in the process of spraying pesticides, pesticides are sprayed on some inappropriate parts, such as some pesticides are to be sprayed on the leaves of crops, but if sprayed to the roots of crops, it may lead to the death of crops, so pesticide damage is caused by improper operation in the process of spraying pesticides.

2. What should I do if the drug is harmed? In this case, if you want to recover economic losses, then you need to do some remedial measures, you can first properly water the crops with pesticide damage, dilute the pesticide residues, in addition, you can also use some detoxification drugs, and then there is a proper use of some fertilizers to let crops absorb certain nutrients, so that pesticide damage can be partially decomposed, and the harm of pesticides to crops will be greatly reduced. However, these treatment methods must be operated in a timely manner, once the best time has passed, the pesticide damage will be irreversible.

3. How to avoid the appearance of pesticide damage? The appearance of pesticide damage is caused by human reasons, so if you want to prevent it, only in the process of spraying pesticides, pay attention to controlling the amount of pesticides sprayed, and must follow the growth characteristics of crops, its own growth characteristics to spray pesticides, and also according to the applicability of the pesticides themselves to use, do not spray pesticides on crops that are not suitable at will, in addition, crops spraying pesticides should also be sprayed at the right time, the effect is the best, if there is a special person to guide, then it can effectively avoid the occurrence of these problems, so when spraying pesticides, it must be carried out in a reasonable way, at a reasonable time and with relevant instructions.

You can choose drainage and irrigation remediation, top dressing remediation, etc. Drainage and irrigation remediation, proper drainage and irrigation can reduce the degree of pesticide damage; Top dressing remediation, this method can be used for crops that produce leaf pesticide damage.

It must be remedied in time, watered immediately, and dredged the waterways immediately to prevent serious consequences, and fertilizer should be replenished in time.

For example, if the plant wilts, the leaves will turn yellow and spots, the plant will be deformed or stagnant, and the leaves or fruits will fall off.

There will be symptoms of non-flowering, slow growth, plant decay, and slow plant development, all of which are symptoms of being damaged by pesticides.

There will be dryness, yellowing, spots, deformities, growth stagnation, infertility, and fruit shedding.

Leaf yellow growth stagnation will be triggered.

1. Rinse with a large amount of water or slightly alkaline water. For the earlier discovery of pesticide damage, can be quickly sprayed with a large amount of water to spray the foliage of the pesticide damage, try to wash off the drug on the surface of the plant limbs, in addition, because most of the current pesticides encounter alkaline substances are relatively easy to reduce the effect, can be sprayed with water to add an appropriate amount of baking soda solution or lime water, rinse or wash, in order to speed up the decomposition of the agent. At the same time, due to a large amount of water washing, the crop absorbs more water, increases the water in the crop cells, and can play a certain role in diluting the concentration of pesticides in the crop body, and can also play a role in reducing the pesticide damage to a certain extent.

2. Quickly apply fast-acting fertilizer. On crops where pesticide damage occurs, rapid topdressing of fast-acting fertilizers such as urea can increase nutrients, enhance crop growth vitality, promote early emergence, and accelerate crop recovery ability, which has obvious effects on seed buds and seedlings with less damage.

3. Spray drugs to alleviate pesticide damage. For the agent that causes the drug damage, spray the agent that can alleviate the drug damage. If crops are damaged by dimethoate, borax solution can be sprayed on crops; Pesticide damage caused by copper sulfate or Bordeaux liquid can be sprayed with lime water.

4. Remove the parts with serious pesticide damage. This measure is often used on fruit trees. For example, in the fruit trees using perfusion, injection, bandaging and other methods, the use of strong systemic insecticides, if the pesticide damage occurs due to the application concentration is too high, the more damaged branches, should be quickly removed, so as to avoid the pesticide continues to conduct and penetrate; At the same time, water is quickly irrigated to prevent the pesticide damage from continuing to expand.

<> "The wide application of pesticides, fungicides, herbicides and various plant hormones in production makes crop pesticide damage inevitable. Therefore, controlling the types and symptoms of damage caused by plant drugs and taking preventive and control measures in time are issues that cannot be ignored in the safe use of pesticides.

1.Pesticide Residue Damage This type of pesticide damage is characterized by the fact that the current crop is not damaged by pesticides after application, while chemicals left in the soil can cause pesticide damage to the crops that are most vulnerable to the next harvest. The use of simazine herbicides in corn fields often causes damage to the drug for the next crop, such as canola and legumes.

This type of pesticide damage usually occurs during the seed germination phase of the next harvest. For example, the root tip, plant tip and other parts turn brown or rot, affecting normal growth; In severe cases, rotting seeds and sprouts can reduce the incidence of emergencies, or they may not occur. This drug damage is difficult to diagnose and can easily be mistaken for fertilizer damage.

Misdiagnosis can be avoided by understanding the cultivation and management of previous crops, the history of pesticides, geotechnical tests, and other measures.

2.Chronic drug damage does not show symptoms immediately after medication, has a certain incubation period, prevents the growth of crops, deteriorates the taste of fruits, etc. This type of drug damage is often difficult to diagnose and can be easily confused with other physiological conditions.

Methods for understanding the occurrence of diseases and plagues, the type of application, the quantity, the area, and plant control can be used for diagnosis.

3.Acute drug injuries are characterized by rapid onset and prominent symptoms. In general, symptoms may appear within a few hours of taking the drug.

It usually manifests as punctate, perforated, burned, curled, deformed, wilted, yellow, chlorine, or albino of the culture leaves. The damage caused by the roots is characterized by short and thick roots, sparse, yellowish or thickened root bark, peduncles, and damage to the seeds indicates that it is unable to germinate or germinates slowly. Plant damage is characterized by flower drop, bud drop, fruit deformity, atrophy, defects, brown fruit, rust, fruit drop, and the damage of such pesticides is mainly caused by excessive use of pesticides or improper treatment of seeds by pesticides.

It can be determined according to the growth of the plant, according to the root of the leaf of the plant, and if there is a problem with the root of the leaf of the plant, it can be confirmed.

The wide application of insecticides, fungicides, herbicides and various plant hormones in the production makes crop pesticide damage inevitable, therefore, mastering the types and symptoms of crop pesticide damage and taking timely prevention and control measures is a problem that cannot be ignored in the safe use of pesticides.

It is mainly based on the damage of the crop and whether there will be relief after dilution of the soil, and it can be confirmed through these actions.
