How to remedy pesticide damage in greenhouse vegetables

Nowadays many people grow vegetables using greenhouse technology, artificially regulating the market timing of vegetables through greenhouses to obtain greater profits. But greenhouse vegetable cultivation inevitably involves the use of pesticides, and once too much pesticide is sprayed it will cause pesticide damage. So what should be done when pesticide damage occurs in greenhouse vegetables? Let's take a look.

1. Remove the leaves

Many pesticides currently have systemic properties, so after pesticide damage occurs, the first thing to do is remove the leaves that suffered the damage, so the plant does not continue to absorb the pesticide, which can reduce the impact of the pesticide damage. However, when removing leaves, pay attention to the amount; do not remove good leaves, so as not to affect the plant's later growth. At the same time, also be careful not to let the pesticide liquid remaining on the leaves fall onto other leaves or plants.

2. Spray clean water

If pesticide damage occurs in a small area of vegetables, removing leaves can relieve and reduce the pesticide damage, but once pesticide damage occurs in a large area of vegetables, the speed of leaf removal is slower, it is not suitable to operate, and the losses are relatively large. At this time, watering can be carried out. After pesticide damage occurs, water and spray clean water to wash the leaves, reduce the pesticide liquid remaining on the leaves, prevent it from being absorbed by the plant, and at the same time dilute the pesticide liquid so that it drops to a range the plant can tolerate.

3. Spray remedy chemicals

There are special pesticide damage remedy chemicals. When pesticide damage occurs, in order to relieve the pesticide damage, such chemicals can be sprayed. They can not only relieve the pesticide damage but also promote better growth. When growing greenhouse vegetables, there are many pests and diseases, so pesticides have to be sprayed, but pay attention to the timing of application, and it is not easy to mix them together. Follow the pesticide specifications, and it is not easy to increase the dosage.
