How to improve the use effect of bacterial pesticides

pubdate:2016-01-27 00:00 source:http://www.propuestasyservicios.com Click:

⒈. Cyanuric chloride observation temperature: the suitable temperature for using bacterial pesticides is above 25℃. When the temperature is low to a certain level, the insecticidal effect is completely lost. Using bacterial pesticides at 25-30°C, the control effect is 1-2 times higher than that at 10-15°C. Therefore, it is best not to use bacterial pesticides when the temperature is below 20°C.


⒉. The synthetic ammonia manufacturer observes the humidity: the greater the environmental humidity, the better the efficacy of bacterial pesticides. Therefore, the use of bacterial pesticides should be carried out in the morning and evening when there is dew, in order to facilitate the adhesion of the fungus to the stems and leaves, promote the propagation of spores, and increase the chance of contact with pests. In addition, the wetter soil helps the adsorption of the fungus, thereby improving the insecticidal effect.


⒊. Pesticide manufacturers observe sunlight: In order to reduce the damage of ultraviolet rays in the sun to bacterial spores, it is best to use bacterial pesticides on a cloudy day or after 4 pm. If you can add crude molasses or corn syrup to powdered bacterial pesticides, It will have a certain effect on filtering ultraviolet rays.


⒋. Observe the rain: moderate to heavy rain will wash away the bacterial pesticide sprayed on the stems and leaves of the plant, reducing the control effect. If it is drizzled 5 hours after spraying, it will increase the effect of prevention. In order to ensure the efficacy of the medicine, it should be applied on cloudy or light rain days under the premise of no moderate to heavy rain within 1 to 2 days after application. After applying the pesticide, if it encounters heavy rain, it should be applied immediately after the rain. At this time, the insecticidal effect is best.


⒌ Observe the wind: the application of bacterial pesticides is wasteful in windy days, especially the powder, which causes more loss. At the same time, windy days are not conducive to the germination of spores. Therefore, bacterial pesticides should be applied in calm or breezy days.
