Pesticide phytotoxicity often occurs, pesticide phytotoxicity is not an incurable disease. Nowadays, the technology is developed and there are corresponding countermeasures. In addition to these, pesticide phytotoxicity should be avoided as much as possible, and crops are in different stages of growth. When using different pesticides, phytotoxicity may occur under different weather conditions. How to avoid these common phytotoxics? The pesticides are compiled in four ways to avoid the occurrence of pesticides:

First, the choice of pesticide varieties

Choose a regular manufacturer and a qualified pesticide variety. Secondly, the use of any pesticide is inseparable from the selection of the appropriate type, and should be applied at the appropriate time of the crop, and sprayed with suitable equipment and methods. Furthermore, it is necessary to strictly follow the method of use during use, which is the most fundamental measure to avoid the occurrence of phytotoxicity. After fully understanding the characteristics of the pesticide according to the product label, and then understanding the crop variety, different growth period and the sensitive period of the crop, it can avoid the occurrence of phytotoxicity.

Second, choose the right weather temperature

It should also be noted that it is best not to apply the drug under special weather conditions such as high temperature or low temperature, drought or high humidity, strong light or haze, because it is beneficial to spray pesticides under the weather conditions of 25~30 °C and sunny breeze. Slowly spread on the surface of the crop body to fully exert its efficacy.

Third, the mixing should pay attention to

Do not use excessive amounts of pesticides and mix them at random. In theory, do not use more than three kinds of pesticides. When diluting the pesticide, first use a small amount of water, mix one of the medicines well, and then pour into the latter medicine to avoid chemical reaction between the direct contact between the chemicals, forming a risk of phytotoxicity.

Fourth, spray equipment selection

Be sure to choose a spray device that has a good atomization function and can maintain a stable pressure. According to different control objects, select a more suitable nozzle and spray the liquid evenly. For example, spraying a herbicide must use a fan-shaped spray head for straight walking, so that the sprayed liquid is more uniform.

Once the phytotoxicity occurs, you need to know how to remedy it. Be sure to do a good job in drug analysis, and determine the cause of the drug damage and take targeted measures. For example, after herbicides produce phytotoxicity, it is generally necessary to spray plant conditioners or nutrient fertilizers such as calcinein, cytokinin, seaweed, humic acid, etc., to promote the plant to accelerate cell division and growth, while cultivating loose soil and strengthening surface soil. Permeability, which is conducive to root growth.
