Bacterial pesticides have the advantages of high insecticidal efficiency, non-pollution of the environment, non-toxicity to humans and livestock, and non-induction of resistance to insect pests. However, they have been promoted to a large extent, and many farmers still have unsatisfactory results after use. According to the survey, the main reason was that farmers did not fight drugs according to the requirements of external conditions of bacterial pesticides. The insecticidal effect of bacterial pesticides is related to the number and activity of bacteria. When using them, 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.
The Platewarmer uses minimum of energy due to the grid design of the heating element and provides a practical way to heat 3-12 plates in less time than it takes to cook a meal, leaving room in your oven for the cooking. To use the Plate Warmer, simply place up to 4 plates in each fold and switch on.
Electric Plate Warmers are thermostatically controlled to keep the plates at the ideal temperature to serve hot food whilst leaving the outer edges safe to handle and are a safe and easy alternative to heating up plates in the oven. The Electric Plate Warmer can be personalised with your own bespoke logo and/or design colour.
