Description

Technical Field

[0001] This invention relates to the field of agricultural chemicals technology, specifically to a pesticide repellent additive for preventing pesticide poisoning in pollinating bees and its preparation method. Background Technology

[0002] Honeybees are the primary pollinating insects of angiosperms. Globally, over 70% of crops and wild plants, including most fruits and agricultural products, rely on honeybees for pollination. Honeybee pollination directly impacts the yield and quality of most agricultural products and is crucial for maintaining ecosystem stability and diversity. Beyond providing vital pollination, honeybees also produce many valuable products such as honey, beeswax, pollen, and propolis. These products have wide applications in daily life, serving not only as food and nutritional supplements but also in medicine, cosmetics, and candles, making a significant contribution to the global economy. Protecting honeybees and promoting their reproduction is essential for maintaining ecosystem health and sustainable human development. However, with the development of modern agriculture, people have become heavily reliant on pesticides to control agricultural and forestry pests. Although efforts have been made to use pesticides that are friendly to humans and the environment, while these pesticides play a crucial role in controlling pests, they also cause serious harm to the environment and beneficial insects. Many pesticides are highly toxic to non-target insects such as honeybees, leading to a sharp decline in their numbers. This not only affects crop pollination but also disrupts the ecological balance. To effectively address the thorny issue of balancing agricultural and forestry production with bee protection, the development and use of repellents or pesticides containing repellents are imperative. This would allow for effective repellent of bees during pesticide application. When bees are out collecting nectar, they will automatically avoid flowers containing pesticides upon smelling the repulsive odor, thus reducing direct contact between bees and pesticides. This approach not only avoids impacting the control of pests and diseases in agricultural and forestry crops but also protects the health of bee populations in fields and forests to a certain extent.

[0003] Honeybees are vital pollinating insects and crucial to agricultural production. However, the widespread use of pesticides has led to frequent cases of bee poisoning, especially with neonicotinoid insecticides (such as thiamethoxam and imidacloprid), where bee mortality rates have significantly increased. Although existing technologies propose adding repellents to pesticides, their repellent effects are limited. Therefore, there is an urgent need for a highly efficient and environmentally friendly repellent additive that can effectively protect bees while being compatible with pesticides.
