Bio-pesticide has the advantages of broad-spectrum, high-efficiency, safety, no drug-resistance, no killing of natural enemies, etc. It can prevent pests that have been resistant to traditional products without cross-resistance: generally beneficial to people, animals and all kinds of benefits. The biological safety is relatively small, and the impact on non-target organisms is relatively small, so it is a breakthrough to realize the technological transformation of pollution-free agricultural production.
1, use time.
Biological pesticides are mostly delayed-type, so the application time should be several days earlier than the use of chemical pesticides. The specific advance time is based on the characteristics of each biological pesticide.
2, air humidity.
Bio-pesticide with the increase of environmental humidity, the effect is also significantly improved, so it is necessary to spray bio-pesticide (powder) in the presence of dew to have the desired effect.
3. Light intensity.
Ultraviolet light in sunlight has a lethal killing effect on active substances in biological pesticides. Therefore, biological pesticides should generally be sprayed before 10 am, after 4 pm, or on cloudy days.
4. Ambient temperature.
When spraying bio-pesticide, it is necessary to master the temperature above 20 °C. According to the test, at the temperature of 25-30 °C, the bio-pesticide effect after spraying is 1-2 times higher than the insecticidal efficiency of 10-15 °C. In addition, please note that in addition to clearly indicating the types allowed, try not to mix with other chemicals; store in a cool, dark place, avoid high temperature or exposure, away from fire; use with the use, avoid prolonged placement.
