What are the advantages of bio-pesticides? What should you pay attention to when using it?
Bio-pesticide is believed to be familiar to everyone. It refers to a preparation that uses biological living organisms such as bacteria or fungi, or some metabolites, to control some harmful organisms in agricultural planting. Biological pesticides are also called natural pesticides because they are not synthesized by chemicals, but they have a bactericidal and insecticidal effect, so they have been popular in the market in recent years. However, many people do not understand biological pesticides. Today, Xiaobian will give you a comprehensive introduction to the advantages of biological pesticides and precautions for use. First, the advantages of biological pesticides 1. The toxicity of biological pesticides is usually lower than that of traditional pesticides. 2. Biopesticide is highly selective and harmless to humans, birds and other unrelated insects and mammals. 3. Biological pesticides are usually low-residue and highly efficient. A very small amount of bio-pesticides can play a high-performance role. And it usually breaks down quickly, avoiding environmental pollution problems. 4. Crops are not susceptible to drug resistance. 5. It can greatly reduce the use of traditional pesticides without affecting crop yield. Second, the use of biological pesticides 1. Master the temperature and spray it in time to ensure the prevention and control of pests and diseases. 2, grasp the humidity of the environment, spray at the time to ensure the quality of prevention The requirements for humidity of biological pesticides are very strict. The greater the humidity in the farmland, the more obvious the efficacy of bio-pesticides. Therefore, when used on edible agricultural products such as vegetables, melons and fruits, it is necessary to make the agent adhere well to the stems and leaves, so that the spores can rapidly multiply, and as soon as the pests are eaten to the leaves, the effects are immediately effective. Control effect. 3, avoid glare, enhance spore vigor, give full play to the efficacy Ultraviolet light in the sun has a lethal killing effect on spores. Moreover, the ultraviolet radiation can also cause deformation and effect on the parasporal crystal. Therefore, avoid strong sunlight, enhance the vigor of the spores, and exert the effect of spore control. 4, avoid heavy rain wash, timely medication, to ensure the killing of pests Spores are most afraid of torrential rain, and the rain will wash away the bacteria sprayed on vegetables, fruits and other crops, affecting the lethality of pests. If it encounters light rain after spraying, it is beneficial to the germination of spores, and the insects will accelerate their death after eating, which can improve the control effect. To this end, local agricultural technicians are required to guide farmers to use biological pesticides. According to the local weather forecast, biological pesticides should be used in a timely manner. It is strictly forbidden to use drugs during heavy rain to ensure their insecticidal effects. Xiao Bian finally reminds everyone that although the advantages of bio-fertilizers are many, it has indeed brought us many benefits in crop planting. However, we should pay attention to the choice of the variety and the precautions for its use. 7 Inch Biometric Tablet,7'' Android Biometrics Fingerprint Tablet,7-Inch Rugged Industrial Tablet,7'' Android Fingerprint Rfid Tablet Shenzhen Bio Technology Co., Ltd , https://www.hfsecuritytech.com
