Factors affecting bacterial biopesticides

Bacterial bio-pesticide is a new type of protective agent that is currently used in the pollution-free cultivation of vegetables. Since the weather conditions directly affect the bacterial activity in the bacterial pesticides, which affects the effect, special attention must be paid to the weather conditions during use.

First, the temperature

The active constituents of bacterial biopesticide are protein crystals and living spores. Under low temperature conditions, spores are slow to propagate in pests, and protein crystals are not easy to function. According to the test, the efficacy of applying bacterial bio-pesticides at a temperature of 25 to 30 ° C is increased by 1 to 2 times at 10 to 15 ° C.

Second, humidity

The spores of bacteria in bacterial bio- pesticides are in a humid environment. Therefore, the greater the humidity in the field, the higher the efficacy, especially the spraying of powdered biological pesticides should pay attention to the field humidity. Generally, the bacteria powder is sprayed in the morning and evening when there is dew, so that the microbial agent can adhere to the stems and leaves of the crop well, and promote the spore propagation and improve the drug effect.

Third, the sun

Ultraviolet rays in the sun have a killing effect on spores. According to the test, direct sunlight for 0.5 hours, the spore mortality rate is about 50%; direct radiation for 1 hour, the spore mortality rate is 80%. In addition, ultraviolet radiation can degrade the parasitic crystals. Therefore, spraying biological pesticides should be carried out in the evening or on cloudy days.

Fourth, rain

Shortly after spraying the biological pesticides, in case of heavy rain, the bacteria sprayed on the stems and leaves of the crops will be washed away to reduce the efficacy; but if it rains after 5 hours of application, it will not reduce the prevention. Efficiency, but has synergy.

Using methods

1. Glue gun using voltage is 110-220V AC,50/60Hz;

2. Tip gun forward on stand and place a piece of cardboard under the nozzle

3. Use 7-8mm (mini trigger glue gun), 11-12(big trigger glue gun), insert glue sticks through
tunnel at back of gun

4. After power, wait for 5-10 minutes to allow glue to soften

After glue softens, squeeze trigger to feed glue through glue barrel. Excessive force will damage glue gun. Put down nozzle after work, disconnect the power plug
