In the use of pesticides, problems such as abuse or unscientific dosage formulation often occur, resulting in less than ideal results. Therefore, be sure to pay attention to the following issues when using pesticides. Be careful not to abuse pesticides 1 It is not allowed to abuse banned pesticides in certain crops, such as fruits and vegetables, methamidophos, 1605 and other highly toxic pesticides. 2 It is not allowed to abuse pesticides during the banned period of pesticides. For example, it must not be sprayed to kill Pinus sylvestris in the 14 days before rice harvest. 3 can not be mixed with pesticides, such as 1605 can not be mixed with rice bran (mixed toxicity increase), calcium arsenate can not be mixed with the exuerate pesticides, dimethoate can not be mixed with lime sulfur or Bordeaux mixture, WP can not be Emulsion mixed use. Pay attention to choose reasonable dose When formulating pesticides, farmers' friends are accustomed to diluting by feeling. This is unscientific. If the pesticide is formulated with too much concentration, it will easily cause damage to the crops, produce resistance to pests and diseases, and cause environmental pollution and toxic effects such as human and livestock poisoning. If the preparation is too dilute, it will not achieve the control effect. Therefore, pesticides should be formulated in strict accordance with instructions for the use of pesticides or guidance from agricultural technicians, and the dosage should be properly grasped during the application process. When spraying, it is required to achieve a uniform, thoughtful, and appropriate amount (in order to fully wet the foliage and not lose it). An excessive number of pesticides are continuously used on the same crop, which makes them easy to produce drug resistance or drug resistance, and the control effect is gradually reduced or even invalid. Therefore, care should be taken to use cross-cutting pesticides. In short, when it comes to the prevention and control of pests and diseases in crops, it is necessary to implement the principle of prevention and integrated prevention and control, and actively adopt various effective non-chemical control measures.
