What to Do About Herbicide Damage in Wheat? A Detailed Guide to Remedial Measures

Wheat is a widely grown cereal crop, and during cultivation, chemicals are unavoidably used to control diseases.If used improperly and wheat suffers herbicide damage, what should you do?

1. What to do about herbicide damage in wheat?

1. Flucarbazone (flucarbazone-sodium) damage: When damage occurs before winter, irrigate with green-up water at the appropriate time and apply fertilizer at the stem-elongation stage to promote early recovery of normal growth in the wheat seedlings, combined with spraying phosphorus-potassium source reservoir, brassinolide, sodium nitrophenolate, etc., for 2 to 3 consecutive applications. When wheat seedling growth is severely inhibited, an appropriate amount of gibberellin may be added.

2. Fluoroglycofen-ethyl damage

Strengthen fertilizer and water management, and spray quick-acting fertilizer. If dead seedlings appear in large patches, consider replanting early.

3. Phenoxycarboxylic acid damage

Depending on the extent of the damage, spray brassinolide, gibberellin, naphthaleneacetic acid, etc., to comprehensively regulate and restore the normal physiological functions of wheat, promote faster cell division, and encourage root growth.

4. Carfentrazone-ethyl damage

After damage occurs, spray quick-acting fertilizer and foliar fertilizer as early as possible, and firmly strengthen fertilizer, water, and cultivation management. If large patches die, consider replanting early.

In addition, the following points also need to be done well:

1. Irrigate to flush out toxins

When herbicide damage occurs, be sure to immediately irrigate to flush out toxins and drain the toxic irrigation water from the field. You can continuously flush with fresh water, or combine drainage with the application of lime and other methods to neutralize acidic herbicides in the field and reduce the damage. For damage on plants, sprinkler irrigation or spray water can be used to rinse off residual chemicals on the affected plants, which can effectively reduce the damage.

2. Apply more fertilizer

Management of affected wheat fields must be strengthened. In terms of fertilization, pay attention to applying more Zuotianshi organic fertilizer. The organic matter in it can act as an adsorbent for herbicides, causing the herbicides to lose part of their activity.

3. Inspect fields and replant in time

For plots where herbicide damage is severe, causing dead wheat seedlings or preventing stem elongation and heading, promptly destroy and replant or switch to other crops to minimize herbicide damage losses.

4. Use detoxifying chemicals

A commonly used detoxifying chemical such as gibberellin: use 2 grams per mu, dilute in 50 kg of water, and spray evenly on the wheat seedlings. This can stimulate wheat seedling growth and reduce herbicide damage.
