What to Do When Peach Trees Suffer Pesticide Damage? Here Are the Remedies

The peach tree is one of the most common fruit trees in our daily life. Every spring and summer, peach trees bloom with crimson flowers all over, and a whole grove of peach blossoms is an even greater sight. However, in the process of growing peach trees, pesticides must be used to support their growth, but spraying too much can also cause pesticide damage to peach trees. So what should be done when peach trees suffer pesticide damage?

I. Pesticide damage to peach trees

Among fruit trees such as apple, pear, peach and grape, the peach tree has the poorest tolerance to pesticides and has allergic reactions to many pesticides. In particular, when using copper-based and organophosphorus formulations, take care not to increase the concentration arbitrarily; when using copper sulfate, it is best to mix it with zinc sulfate to prevent pesticide damage. After a peach tree suffers pesticide damage, symptoms such as scorched spots and yellowing will appear. Targeted remedial measures should be taken according to the specific symptoms of pesticide damage, and they cannot be lumped together.

Scorched spots and yellowing occur 1—2 days after spraying, when the leaf surface of the peach tree quickly develops chlorosis or yellow-brown spots, and in severe cases the leaves wither and die. After these symptoms appear, a sprayer can be used to spray clean water to wash off the pesticide powder on the plants, then irrigate the peach orchard and drain it quickly to reduce pesticide residue. After that, apply a quick-acting fertilizer to promote new leaf growth and make up for the losses caused by the toxicity.

The specific measures to reduce pesticide damage are generally spraying a large amount of clean water or washing with slightly alkaline water, promptly applying fertilizer, spraying drugs to alleviate pesticide damage, carrying out appropriate drainage and irrigation, and removing the parts with more severe pesticide damage, etc. Corresponding measures can be taken according to the severity of the pesticide damage.

II. Key points for growing peach trees

The planting time of peach trees should be determined according to the local climate, the source of seedlings and other conditions. A suitable planting time helps increase the survival rate of seedlings, shorten the recovery period, make the trees grow quickly and take shape early. After planting, cultivate and loosen the soil and remove weeds in time. After leaf fall, clean the orchard, and after spraying to prevent pests and diseases, bury the weeds and fallen leaves deep under the trees. When fertilizing peach trees, fertilize early; especially for trees bearing too much fruit, fertilize even earlier, and for late-maturing varieties, apply before harvest. Before peach trees bloom, at the young fruit stage and at the fruit enlargement stage, also spray Zhuangguodiling once each time to thicken the fruit stem and increase the amount of nutrient transport, so as to form fruit with better taste and texture.

The above are some tips on growing peach trees. When growing peach trees, observe more, and for peach tree diseases, detect them early and prevent and control them early.
