Herbicide, phytotoxicity, remedy

Most of the greenhouse vegetables are broad-leaved vegetables, such as cucumbers, melons, and pumpkins of the cucurbitaceae, cowpeas, peas, soybeans, etc., eggplant and peppers of the family Solanaceae. Among the herbicide types, the commonly used sulfonylurea herbicides mainly rely on the absorption and transmission of plant roots, stems and leaves to kill weeds, and the phytotoxicity to broad-leaved vegetables is quite serious.

First, the cause of serious phytotoxicity: 1. High temperature in the greenhouse, good fresh water conditions, and high humidity, which is conducive to the full play of the efficacy of the herbicide. 2. Sulfonylurea herbicides are mainly used to control broadleaf weeds, but broad-leaved vegetables are also very sensitive to it, and the phytotoxicity is heavy. 3. Many vegetable varieties in the greenhouse are cultivated in three-dimensional frame, and the liquid is easily distributed everywhere and drifts to the young part, and the probability of occurrence of phytotoxicity is large and heavy. 4. Herbicides are mostly used in field crops, vegetable fields are used less, and greenhouse vegetables are less. Therefore, vegetables in greenhouses have poor resistance to chemicals and serious phytotoxicity.

Second, the remedies for phytotoxicity: 1. Vegetable fields with serious phytotoxicity, generally can not be restored, can be immediately removed and replanted (from 30 days after application), can grow soybeans and other legume vegetables. 2. The phytotoxic light plot immediately sprays poison and plant physiological regulators, such as auxin, gibberellin, and cytokinin, to prevent organ detachment, promote cell division and inhibit aging. 3. Strengthen water and fertilizer management. Fertilizers use foliar fertilizers and micro-fertilizers containing zinc and iron.
