Guidelines to be followed when administering bacterial insecticides
Bacterial insecticides are among the earliest microbial pesticides, with the largest production volume and the broadest application range in domestic research and development. These biological pesticides utilize microorganisms or their metabolites to control harmful pests in agriculture. When applying bacterial insecticides, it is essential to follow some important guidelines to ensure optimal performance:
First, always use high-quality products from reputable pesticide manufacturers and authorized retailers. Avoid counterfeit or low-quality products, as they may not be effective. Check the manufacturing date and shelf life of the product, and store it properly to prevent degradation or loss of potency due to expiration.
Second, avoid using bacterial insecticides in cold conditions. The active ingredients—protein crystals and living spores—are less effective at low temperatures. Spore germination and protein crystal activity are significantly reduced, which can lower the overall effectiveness of the treatment.
Third, ensure that the environment is sufficiently humid when applying bacterial insecticides. Bacterial spores thrive in moist conditions, so higher humidity in the field improves efficacy. When applying powder-based biological pesticides, it's best to do so during early morning or late evening when dew is present. This helps the microbial agent adhere better to plant surfaces, promoting spore propagation and enhancing the insecticidal effect. For vegetables, spraying half an hour before sunrise or during foggy mornings is particularly effective.
Fourth, avoid mixing bacterial insecticides with fungicides such as carbendazim or thiophanate-methyl. These chemicals can kill or inhibit the growth of beneficial bacteria, reducing the effectiveness of the insecticide. Even if a sprayer was previously used for a biocide, it should be thoroughly rinsed before applying bacterial insecticides to prevent contamination.
Fifth, minimize exposure to strong sunlight. Ultraviolet (UV) rays can damage spores and reduce their viability. Studies show that direct sunlight for 30 minutes can kill about 50% of spores, while one hour of exposure can lead to an 80% mortality rate. UV radiation can also degrade the parasitic crystals. Therefore, it's best to apply bacterial insecticides on cloudy days or during periods of low light, such as early morning or late afternoon.
Lastly, avoid heavy rain immediately after application. Rain can wash away the applied bacteria from plant surfaces, reducing their effectiveness. However, light rain within five hours of application may actually enhance the performance of bacterial insecticides, as it helps spores spread more effectively both inside and outside the pest’s body.
