Don't Panic About Herbicide Damage in Fruit Trees - All the Latest Remedies Are Here

Irrigation and Spraying Water

If damage occurs early, the affected plants should be rinsed immediately with water. If the damage is caused by systemic pesticides such as carbofuran granules applied to the soil, drainage and washing measures should be taken promptly, that is, first flood-irrigate the orchard surface, then irrigate once more with a quick-flowing water flush.

Spraying Neutralizing Agents

If the damage causes leaf whitening, granular 50% sodium humate (first dissolved in a small amount of water) can be made into a 3000-fold solution for foliar spraying, or a 5000-fold solution for irrigation; after 3 to 5 days, the leaves will gradually turn green again. If the damage is caused by copper sulfate ions in Bordeaux mixture, a 400 to 500-fold rice vinegar solution can be sprayed. For damage caused by improper use of dimethoate, a 200-fold borax solution can be sprayed 1 to 2 times. If the damage is caused by mistaken or excessive use of organophosphorus, pyrethroid, carbamate and other pesticides, a 0.5% to 1% lime water or washing powder solution can be sprayed for detoxification.

Timely Topdressing

After fruit trees suffer pesticide damage, their growth becomes weak. A foliar spray of 0.3% urea solution + 0.2% monopotassium phosphate solution can be applied once every 15 to 17 days, for 2 to 3 consecutive sprays.

Loosening and Mounding Soil

The orchard soil should be cultivated and loosened in a timely manner to a depth of 10 to 15 cm. Manual mounding should be done around the root crown, and phosphorus and potassium fertilizers should be added to promote root development and enhance the fruit trees' recovery ability and virus resistance.

Moderate Pruning

Cut off dead branches and remove dead leaves.
