Biopesticides is a stable, high insecticidal efficiency and no pollution, is not toxic to humans and animals, natural enemies do not hurt, but will not induce resistance to pests pesticides. The following points should be noted when applying: Thick Slices Blister,Abs Blister,Vacuum Forming Plastic Masks Tianrui Fiberglass Composites Co., Ltd. , http://www.sdfiberglassmesh.com
1. Illumination: Ultraviolet rays in the sun have a lethal killing effect on spores. Scientific experiments have shown that in just 30 minutes under direct sunlight, the spore kill rate is about 50%; after 1 hour of irradiation, the spore mortality rate is as high as 80% or more. Ultraviolet radiation can also cause deformation and effect on the parasporal crystals, thus greatly reducing the efficacy of biological pesticides. Therefore, it is necessary to select the application before 10:00 am, after 4 pm or on cloudy days to receive the desired effect.
2. Rainwater: Spores are most afraid of torrential rain, so it should be carried out according to the weather forecast, because the rain will wash away the bacteria sprayed on the plants, so that the biological pesticides lose their lethality, but if sprayed for 5 hours, Light rain will not only reduce the efficacy, but will improve the control effect.
3. Temperature: When spraying bio-pesticide, be sure to keep the temperature above 20 °C. Because the active ingredient of biopesticide is composed of protein crystals and living spores, if sprayed below the above temperature, the spores will be very slow in the body of the pest, and the protein crystals will be difficult to play. . According to the test, at the temperature of 25 ° C, the effect of bio-pesticides after spraying is 17 times higher than the insecticidal efficiency of 10 ° C to 15 ° C.
4. Humidity: Biological pesticides are extremely sensitive to humidity requirements. As the environmental humidity increases, the effect of spraying biological pesticides is also significantly improved. Because only in this way, the agent can adhere well to the stems and leaves, and the spores will multiply quickly, expanding the flora, and the pests can be screamed by touching the leaves of the plants or any point.
