How can microbial pesticides be used to increase their effectiveness?
What methods can improve pesticide efficacy? Please give guidance. During pesticide application, if an appropriate amount of auxiliary substance is added, the pesticide efficacy can be significantly improved. Adding baijiu: adding 50 grams of baijiu per mu will significantly improve the insecticidal effect. For example, using 40 milliliters of methamidophrin-cypermethrin per mu plus 50-100 grams of baijiu, add to 5...
How can microbial pesticides be used to increase their effectiveness? Please provide guidance on methods.Microbial pesticides can be used with the following methods to increase their effectiveness:
Suitable concentration, scientific intervals. If the solution content is low, the control effect is poor; otherwise, it is easy to cause waste or pesticide damage. Only by applying a suitable microbial agent at the right time, so that pests and pathogens obtain a sufficient amount of pathogenic bacteria, can the control effect be guaranteed. For example, bacterial insecticides generally use 2200-2500 grams of bacterial powder with a viable spore count above 100 billion/gram per hectare. When the pest population is large, generations overlap, and insect ages are uneven, the pesticide amount per unit area for one application is large, and the interval period is short. Bacillus thuringiensis for controlling diamondback moth and large white butterfly has an interval of 10-15 days, and for controlling rice stem borer, an interval of 5-6 days.
Uniform spraying
Biological pesticides are generally mainly stomach poisons, and uniform spraying can improve the control effect. Before using powder, weigh out the required amount, add a small amount of water and stir into a paste. Before using emulsifiable concentrate, shake it fully, and according to the pesticide amount per hectare, add the required amount of water 750-1000 kilograms and stir evenly. Adding 0.1% synthetic laundry powder, Chinese honey locust pods, or camellia seed powder to the solution as an adhesive helps improve the spraying effect.
Correct formula, mixed use. Biological pesticides have strong specificity in killing insects and preventing diseases. Mixing pesticides can expand the scope of application and improve work efficiency, especially when outbreaks of voracious pests occur, which is very necessary. However, they should not be mixed with alkaline pesticides or systemic organophosphorus insecticides, and mixing with fungicides or antiviral agents is prohibited. When mixing formulas, mix and use immediately; do not leave for a long time.
Re-spray after rain
If it rains on the day of application, re-spray once immediately after the weather clears.
Safe use of pesticides
Biological insecticide pesticides are highly toxic to silkworms. Use is prohibited within 2 kilometers around silkworm areas.
