Pesticide for preventing and controlling fruit tree disease and pest damage and preparation method thereof

Abstract

The invention provides a pesticide for preventing and controlling fruit tree disease and pest damage, and belongs to the technical field of pesticides. The pesticide for preventing and controlling the fruit tree disease and pest damage is prepared from, by weight, 10-30 parts of radix angelicae pubescentis, 10-30 parts of fructus cnidii, 10-30 parts of herb of sophora alopecuroide, 10-30 parts of herb of parochetus communis, 5-20 parts of herba asaricum radice, 5-20 parts of lesser bougainvillea flowers, 5-20 parts of calculus bovis, 5-15 parts of Chinese magnoliavine fruit, 3-12 parts of cacumen biotae, 3-12 parts of folium apocyni veneti, 3-12 parts of herb of solidago virgaurea and 1-10 parts of herba saururi chinensis. According to the pesticide, a synergistic effect is achieved through scientific compounding of the Chinese herbs, the antibacterial and pesticidal capabilities of the obtained pesticide are significantly enhanced, the antibacterial and pesticidal spectrum is wider, and the pesticide resistance of pests is not prone be generated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide for preventing and controlling fruit tree diseases and insect pests and a preparation method thereof. Background technique [0002] China's agricultural modernization has achieved the effect of increasing production on the basis of breeding, chemical fertilizers, chemical pesticides, facilities and other technologies, and has made a decisive contribution to solving the problem of eating enough for the Chinese people.

Problems solved by technology

However, the development and utilization of botanical pesticides is still very slow, and there are many limiting factors, including the low activity of some botanical pesticides, large dosage, weak knockdown power, and slow efficacy, which is not conducive to the development of sudden epidemic diseases and insect pests. Prevention and control; the type and content of active ingredients are affected by their own genetic factors and external environmental conditions such as soil, temperature, light, and soil value, and will have regional and seasonal changes; and the content of active ingredients in different parts of the plant is also different , especially some active ingredients are unstable to light and heat etc.
