There are many reasons for pesticides to produce phytotoxicity. Grasping the right drug technology is the most critical step to prevent phytotoxicity. 1. Use good quality pesticides. Emulsions need clear and transparent, no flocculent, no precipitation, can be dispersed by adding water, no floating oil on the water surface. Powder requirements fine, uniform, no agglomeration. Wettable powders require the addition of water to dissolve in water and disperse evenly. Deteriorating pesticides can cause phytotoxicity. 2. Determine the dosage according to the effective content of the drug. Do not arbitrarily increase or decrease the concentration of the drug when it is diluted with water or soil to the required concentration. 3. Carefully formulate pesticides. When configuring the liquid medicine, first inject a 1/3 amount of water into the clean container, and then put the medicine into the clean container and stir it and fill it with water. When using a wettable powder, first use a small amount of water to make the paste into a paste and then prepare the liquid. With the use of liquid medicine with, can not exist for a long time, otherwise, precipitation or degradation will occur. The water used to dilute the pesticide requires clean soft water. It cannot use water containing more organic matter and hard water containing calcium and magnesium ions. 4. Rational mix of agents. Mixed use of pesticides is worth promoting, but most pesticides can not be mixed with alkaline substances, such as organic phosphorus pesticides can not be mixed with alkaline pesticides such as Bordeaux mixture, lime sulfur mixture. 5. Pay attention to the spraying method. The pesticide should be sprayed evenly and the droplets should not be too thick or heavy. The distance between the nozzle and the crop should be appropriate. When spreading poisonous soil, it is better to use the method of less soil and more to make the spread even. Can also be used according to the need to apply stems, irrigation and other methods of spraying, in order to improve efficacy and to avoid the occurrence of phytotoxicity, such as butachlor to prevent paddy field weeds, spraying stems and leaves than mixing soil easy to produce phytotoxicity. Application of glyphosate is safer with fan-shaped nozzles than with conical nozzles. 6. Continuous use of drugs need to be separated by 7 to 10 days. Do not pay attention to the interval, prone to injury.
