Identifying Pomegranate Phytotoxicity Symptoms and Remedial Measures

Phytotoxicity is a phenomenon caused by improper use of pesticides when crops are being grown. It seriously affects crop growth and yield, and the same is true for pomegranates. Many farmers often encounter phytotoxicity during cultivation. So what symptoms appear when pomegranates suffer phytotoxicity? How should it be remedied? Let's take a look together.

1. Phytotoxicity symptoms

There are quite a few symptoms after pomegranates suffer phytotoxicity. It causes yellow spots, brown spots, net-like spots, and necrotic spots to appear on the leaves. In severe cases, the leaf tips become scorched, and it can also cause yellowing of the stems and leaves. In severe cases, the whole plant turns yellow and withers, often caused by the use of herbicides. It can also cause abnormal growth of roots, leaves, and fruit, affecting fruit quality and appearance. It also inhibits plant growth, leading to slow growth, reduced branching, and decreased yield. During the flowering and fruiting period, it can also cause flower drop, fruit drop, and leaf drop, along with smaller fruit, abnormal fruit surface, and deteriorated quality.

2. Prevention methods

Strictly check the treatment and use methods of pesticides. Pesticides that have deteriorated can very easily cause phytotoxicity, so they must be carefully checked at the time of purchase. When preparing pesticides, the concentration must be strictly controlled to avoid phytotoxicity caused by excessively high pesticide concentration. At the same time, when mixing pesticides, pay attention to their mutual compatibility, so as to avoid pesticide failure or phytotoxicity. For example, emulsifiable concentrates mixed with certain water-based pesticides can easily produce phytotoxicity. When applying pesticides, spray evenly in one pass, and repeated spraying is not advisable. Generally, evenly wetting the canopy until water drips from the leaves is sufficient. For root drenching and fumigation, also pay attention to the dosage.

3. Remedial measures

For phytotoxicity caused by herbicides, methods such as plowing the soil, flooding the field with water, and repeated rinsing can reduce the concentration and dose of pesticides in the soil. If it was sprayed directly onto the leaves, it can be remedied by increasing the application of foliar fertilizer. For phytotoxicity that causes localized pesticide spots, scorched leaf edges, and plant yellowing, applying quick-acting chemical fertilizer can promote plant recovery and reduce the harm. For phytotoxicity caused by a growth regulator, spraying gibberellin can alleviate it, and spraying antidotes or spreading lime, plant ash, or activated carbon can also reduce the harm.
