Bacterial bio-pesticides contain active ingredients such as protein crystals and living spores, which are sensitive to environmental conditions. When temperatures drop below 25°C, the effectiveness of these formulations can significantly decrease. At lower temperatures—such as between 10°C and 15°C—the pharmacodynamic effect is reduced by about 50% compared to when applied at 25°C to 30°C. This is because spores grow more slowly in pests, and the protein crystals take longer to activate and exert their insecticidal effects.
Humidity also plays a crucial role in the performance of bacterial bio-pesticides. Spores thrive in moist environments, so higher humidity in the field enhances their efficacy. When applying powdered bio-pesticides, it's best to do so during times of high moisture, such as early morning or late evening when dew is present. This helps the microbial agents stick better to plant surfaces, improving spore germination and overall effectiveness.
Sunlight exposure can be harmful to bacterial spores. Studies show that direct sunlight for just 30 minutes can kill up to 50% of the spores, while an hour of exposure can result in an 80% mortality rate. Additionally, ultraviolet radiation can break down the parasitic crystals, reducing their potency. To avoid this, it’s recommended to apply bacterial bio-pesticides in the evening or on cloudy days when UV exposure is minimal.
Rainfall after application can have both negative and positive effects. Heavy rain shortly after spraying may wash away the bacteria from plant surfaces, reducing their effectiveness. However, if rain occurs within five hours of application, it can actually help improve the control effect by aiding the spread and penetration of the bio-pesticide into the crop canopy. Therefore, timing of application relative to rainfall is an important factor in maximizing the benefits of bacterial bio-pesticides.
