How to remedy pesticide damage

One is a large number of water showers or slightly alkaline water showers. For the early detection of phytotoxicity, a large amount of clear water can be sprayed on the leaves of crops suffering from phytotoxicity, and the drugs on the surface of plants can be washed off as much as possible. In addition, because most pesticides are easy to fail when they encounter alkaline substances, a proper amount of 0.2% baking soda solution or 0.5% ~ 1% lime water can be added to the sprayed clean water for leaching or washing, so as to accelerate the decomposition of pesticides. At the same time, because a large number of crops are washed with clean water, more water is absorbed and the water in crop cells is increased, which can dilute the drug concentration in crops and reduce the phytotoxicity to a certain extent.

The second is to apply quick-acting fertilizer quickly. On crops with phytotoxicity, quick-acting fertilizers such as urea should be applied as topdressing quickly to increase nutrients, enhance crop growth vitality, promote early development and speed up crop recovery, which has obvious effects on seeds and seedlings and less damage.

The third is to spray drugs to reduce the harm of drugs. Spraying drugs that can reduce drug harm for drugs that cause drug harm. If crops are harmed by omethoate, 0.2% borax solution can be sprayed on crops; For the phytotoxicity caused by copper sulfate or Bordeaux mixture, 0.5% lime water can be sprayed.

The fourth is to remove the parts with serious drug damage. This method is often used on fruit trees. For example, on fruit trees, perfusion, injection, dressing and other methods. A pesticide with strong internal absorption was used. In case of phytotoxicity due to excessive application concentration, the severely damaged branches should be quickly pulled out to avoid further conduction and penetration of pesticides; At the same time, irrigate quickly to prevent the damage from continuing to expand.
