Problems solved by technology

[0004] Among the currently commonly used horticultural flower insecticides, the insecticides with better insecticidal effects are generally chemical insecticides, but these insecticides have a certain degree of toxicity and side effects on horticultural flowers, and will cause soil pollution and pollution to varying degrees. The air environment for planting, while gardening flowers are used for viewing, the spraying of pesticides will affect the viewing of flowers, and the improper use of chemical pesticides will inhibit the photosynthesis of flowers, resulting in abnormal growth of flowers and affecting plant growth.
At present, biological insecticides have also been developed, but such insecticides have complicated preparation methods and high costs; or the insecticidal effect is not very satisfactory, and the drug effect is not good, etc.
