Biological pesticides are the future direction of pesticide development; biological pesticides and chemical pesticides have many advantages, biological pesticides have strong selectivity, and have obvious aftereffects on human and animal safety, small impact on ecological environment, induced pests, and biological pesticide raw materials. The sources are very wide and the production costs are relatively low.
Nowadays, biological pesticides are developing rapidly, and the development of biological pesticides has great advantages. In the future, biological pesticides will be irreplaceable; biological pesticides will not pollute the environment, not poison humans and animals, will not harm natural enemies, and will not induce the emergence of drug resistance. Highly efficient, low toxicity, low residue "no pollution" pesticide. So, what do you need to pay attention to when using bio-pesticides?
I. Considering the climatic factors such as temperature, humidity, sunlight and rainwater. The optimal temperature for the use of biological pesticides needs to be controlled above 20 °C. The test proves that under the condition of 20-30 °C, the biological pesticide control effect is higher than 10-15 °C. 1 to 2 times. To this end, it is important to master the optimum temperature to ensure the effectiveness of spraying biological pesticides. Secondly, the humidity is grasped, and the biological pesticide is extremely sensitive to the humidity requirements. The greater the farmland environment humidity, the more obvious the drug effect, especially the powdered bio-pesticides; the other is to avoid glare, enhance the spore vigor and give full play to the efficacy; when using bio-pesticide, it should be used according to the local weather forecast. Biological pesticides are strictly prohibited from being used during heavy rain to ensure their insecticidal effects.
Second, to ensure the quality of biological pesticides in the purchase of biological pesticides must be purchased by the right manufacturers to prevent counterfeiting, prevention and treatment expired.
Third, can not be mixed with fungicides Bacterial bio-insecticides can not be mixed with fungicides (such as carbendazim , methyl thiophanate), so as not to affect the insecticidal effect.
