In the process of planting crops, various pests and diseases cannot be avoided. When pests and diseases occur, we can choose to use pesticides such as fungicides, insecticides , herbicides and plant growth regulators to prevent and control these diseases, thus reducing the damage that can be caused by our diseases. However, due to the lack of knowledge of pesticides and plant growth regulators, many farmers have not only failed to achieve the desired effect, but have caused phytotoxicity in crops, causing the crops to become obts, causing the fall of the flowers and the growth and development. Not normal, even causing crop death. In the event of such phytotoxicity, we should take necessary measures in a timely manner to reduce losses.
1) In the case of pesticide phytotoxicity, we can give a large amount of water to the farmland for leaching or a little alkaline water to rinse. If it is caused by the spraying of certain pesticides on the foliage and plants, and we find out in time, we can timely water a large amount of water to the affected leaves, and it is necessary to spray the water about 2 to 3 times. As far as possible, the medicine on the surface of the plant should be washed away, and the use of phosphorus and potassium fertilizer should be increased, and the farmland should be cultivated and soiled to promote the normal development of the roots of the crop, thereby improving the ability of the crop to recover. In addition, because we currently apply pesticides, in addition to trichlorfon, these pesticides will be easily decomposed and reduced in efficacy when exposed to alkaline substances. Therefore, we can reasonably add 0.2% alkali surface or 0.5% to 1% lime in the process of spraying the water to quickly wash away the agent.
2) The pesticide network recommends that the quick-acting fertilizer be applied in time. On the crops that need to produce phytotoxicity, quickly apply fertilizers such as urea to improve nutrients, enhance cultivation to increase the growth vigor of crops, promote early growth, and increase the speed of plant resilience. It can be very effective for those seedlings and seedlings that are lightly damaged.
3) Administration of a drug that can reduce the phytotoxicity. For an agent that causes phytotoxicity, an agent that can reduce the phytotoxicity is applied. For example, if the crop is harmed by pesticides such as omethoate and parathion, we can apply 0.2% of the sand solution to the treated plants.
4) Remove those parts of the plant that are more seriously damaged. This measure is often used in fruit trees. Tips for China Pesticide Network : In the fruit trees, you should use the techniques of perfusion, injection, dressing and other medications.
