Bacterial pesticides are biological pesticides with high insecticidal rates, do not pollute the environment, do not poison humans and animals, and do not induce pest resistance. However, the insecticidal effect of bacterial pesticides is related to the number and activity of bacteria. When using the weather, the requirements for meteorological conditions are very strict. Attention must be paid to the following issues:
Temperature: The suitable temperature for the spraying of bacterial biopesticides is between 20 and 30 degrees Celsius. This is because the active ingredients of these pesticides are protein crystals and living spores. At low temperatures, spores propagate very slowly in pests, and protein crystals also Not easy to work. Bacterial biopharmaceuticals were applied at 25-30 degrees Celsius, and the efficacy was 1 to 2 times higher than that at 10-15 degrees Celsius. Humidity: The use of bacterial biological agents for pesticides, the higher the environmental humidity, the higher the efficacy, especially the application of pesticide powdered biological agents, should be carried out in the morning and evening when there is dew, in order to facilitate the bacteria to stick to the base leaf, and promote Spore breeding, improve efficacy.
Sunshine: Ultraviolet rays in the sun have a killing effect on spores. Direct sunlight for 30 minutes, the spores mortality rate of about 50%, the mortality rate of up to 80% in 1 hour irradiation. Therefore, it is best to apply biopesticides after 5 pm or on cloudy days.
Rainwater: Moderate to heavy rain will flush out the bacterial liquid sprayed on the leaves, reducing the efficacy, but if the light rain after 5 hours of application, will not reduce the control effect, but there are synergies.

QS-310 is special non ionic modified surfactant.
it is a special high efficiency Wetting Agent for Bispyribac Sodium SC. With strong affinity, adhesive force and penetration on the surface of plant,greatly reduce the surface tension, greatly improve the fast acting and control efficiency effect of pesticide.
As Tank-mix, 15g 10% Bispyribac-sodium SC,add 15g of the adjuvant,dilute 1000 times before use,or adjust proportion according to local actual situation.
