What to Do When Crops Suffer Herbicide or Pesticide Damage? A Detailed Guide to Remedies

During the process of growing crops, the rational use of pesticides can help crops grow better, but if they cannot be used safely and scientifically, it is easy to cause pesticide damage. So, what should you do when pesticide damage occurs?

1. What should you do when pesticide damage occurs?

1. Rinse with water promptly

For some cases of pesticide damage caused by the application of herbicides, you can water or irrigate appropriately to wash away the pesticide and leach out the toxins, reducing the harmful substances accumulated in the roots. If the leaves have suffered pesticide damage, you can spray clean water several times in a row on the affected areas to remove or reduce the amount of pesticide residue on the crop leaves. If the damage is caused by an acidic pesticide, you can add an appropriate amount of plant ash or 0.1% quicklime to the water when spraying; if the damage is caused by an alkaline pesticide, you can add an appropriate amount of vinegar to the water when spraying, which can lessen and relieve the damage.

2. Remove the affected branches and leaves

Branches and leaves with localized pesticide damage can be removed

3. Apply additional fertilizer

Along with watering, apply a quick-acting fertilizer, or spray a full-nutrient foliar fertilizer.

4. Cultivate and loosen the soil

Combine irrigation and fertilization with cultivating and loosening the soil, which can promote root development and enhance the crop's ability to recover.

5. Spray regulators

According to the needs of the crop, spray foliar nutrient regulators such as Yunda 120 or plant hormones to promote the crop's recovery and growth.

6. Use antidotes

According to the nature of the substance that caused the pesticide damage, you can use a substance with the opposite nature to neutralize and relieve it.

2. What are the main symptoms of pesticide damage in crops?

1. Spots

Within a relatively short time after pesticide application to the crop, yellow spots, brown spots, blighted spots, etc. appear on the leaves, stems, and even the fruit.

2. Yellowing

Young, tender new leaves and new shoots turn yellow, affecting normal growth.

3. Deformity

Common deformities in crops harmed by pesticides include curled leaves, clustered new leaves, root swelling, and deformities of the panicle and fruit.

4. Wilting

Pesticide damage caused by improper use of herbicides causes crops to wilt and even die.

5. Stunted growth

Improper use of growth regulators or herbicides can cause stunted growth in crops.

6. Infertility

Improper use of pesticides during the flowering period often causes infertility and failure to set fruit.

7. Shedding

Improper use of pesticides often causes flower drop, fruit drop, leaf drop, and similar phenomena.

8. Poor fruit

Pesticide damage caused by improper use of pesticides during the fruiting period often shows abnormal fruit growth and deterioration in appearance and quality.

Finally, the editor would like to remind everyone that pesticides all have a certain toxicity, so they must be used safely and rationally.
