What to Do About Hormone Toxicity in Vegetables? Causes and Mitigation Measures

In the process of vegetable cultivation, the use of plant growth regulators has an excellent effect on regulating vegetable growth, increasing yield, and improving quality, but there are also quite a few cases of hormone poisoning caused by improper use on vegetables, so what should be done about hormone toxicity in vegetables? Let's take a look together with the editor.

I. Symptoms of Poisoning

Hormone toxicity mostly manifests as the upper leaves becoming slender and distorted, taking on a "chicken claw" shape, with leaves hard and thick, flowers small or not opening, fruit deformed, and plant vigor declining, which seriously affects later fruit setting and yield. Moreover, these symptoms are very easily confused with the damage caused by viral diseases and mites, so attention must be paid to distinguishing them. Viral diseases have an obvious center of infection, and when they occur they generally manifest as leaf yellowing and stunted plant growth; hormone toxicity, on the other hand, has no obvious center of infection, and when adverse weather lasts for a long time, large areas of leaf deformity are extremely likely to occur.

II. Causes of Hormone Toxicity

1. Variety characteristics. Some varieties are relatively sensitive to low temperatures; after the temperature drops, the plants grow slowly and their own metabolism is relatively poor. In addition, the endogenous hormones produced by seedlings in adverse environments cannot be excreted from the body in time, causing hormone toxicity in seedlings at low temperatures.

2. Growth-inhibiting drugs. When growth-inhibiting drugs are used in too large a single dose or too frequently, drug-induced hormone toxicity is extremely likely to occur.

3. Improper concentration of flower-setting agents. During vegetable cultivation, because there are many flowers, multiple flower- and fruit-preserving operations are needed; if the concentration of the flower-setting agent is too high or flowers are treated repeatedly, hormone toxicity in the upper part of the plant is extremely likely to be induced.

III. Mitigation Measures

1. After hormone toxicity occurs in vegetables, the first thing to do is to reasonably raise the temperature and replenish water, and cooperate with drugs to promote the plants' recovery of vigor; the main drugs should not be sprayed in excess, because abuse will cause hormone toxicity.

2. Next is to reasonably choose flower-setting agents with an appropriate concentration, so as to avoid hormone toxicity caused by too high a concentration.

3. After poisoning occurs, rooting agents and water-soluble fertilizers can be applied in time, choosing regular products from major manufacturers, to promote rapid rooting and recovery of vigor in the plants.

4. When hormone toxicity is relatively mild, first find out the cause, then reduce the amount of hormones input, spray functional foliar fertilizer on the leaves for mitigation, and apply biological bacterial agents or functional rooting agents to the lower part.
