As people increasingly high environmental requirements, more and more attention microbial pesticides, microbial pesticides undoubtedly one of the future direction of development of pesticides.
Microbial pesticides include agricultural antibiotics and living microbial pesticides. To use microorganisms or their metabolites to control diseases, insects, grasses, rodents and crops that endanger crops. It includes treating bacteria with bacteria, treating bacteria with bacteria, and weeding with bacteria.
Advantage of microbial pesticide: microbial pesticide has selectivity, people, livestock, crops and natural environmental safety, do not harm natural enemies, resistance is not easy and so on.
However, there are often some misunderstandings in the use of microbial pesticides in actual operational use. The following section of China's pesticide network will summarize the "wrong areas of microbial pesticide use."
Misunderstandings in the use of microbial pesticides
First, the application of microbial pesticides ignore the weather environment microbial pesticides in the temperature is too low, dry weather or heavy rain days will affect the efficacy. Do not pay attention to environmental factors, do not choose to apply under high temperature weather conditions, even in winter and early spring cold weather conditions, so did not achieve the expected control effect. Tests have shown that between 25 ° C and 30 ° C, the effect of microbial live pesticide control after spraying is 1 to 2 times higher than that between 10 ° C and 15 ° C. Avoiding the high temperature and strong sunlight at noon, after 4 o'clock in the afternoon or on a cloudy day, the effect will be greatly exerted. The spores are most afraid of heavy rain, because the rain will wash away the sprayed bacteria, and the application time should be determined according to the weather forecast.
Second, can not be mixed with bactericidal pesticides
For example, the genus Aspergillus, as a fungal insecticide, is achieved by the action of live spores of O. sinensis. After application, live spores infect aphids and cause death, which can cause continuous infection and cause a large number of deaths. However, as a living fungus, if mixed with an insecticide, they are killed by a bactericide, and naturally lose their insecticidal action.
