The invention also discloses a preparation method of the special insecticide for gardening flowers. The inventionrelates to the technical field of insecticides. The invention particularly provides the special insecticide for the gardening flowers and the preparation method thereof. Through pre-extracted nicotineand bio-oil and insecticide premixed liquid, the insecticidal efficacy of the insecticide is improved, insecticide preparation raw materials are low in collection cost and are environment-friendly and pollution-free raw materials, and through cooperation of various components, the raw materials are high in pesticide effect strength, colorless, odorless, non-toxic to human bodies and suitable forindustrial popularization.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a special insecticide for horticultural flowers and a preparation method thereof. Background technique [0002] In recent years, horticultural flowers have been widely planted in our country. These flowers not only bring ornamental value, but also bring good economic benefits. While the scale of flower planting is constantly expanding, the threat of flowers by diseases and insect pests is also increasing, which has a serious impact on the ornamental value and economic benefits of flowers. The primary threat encountered in the growth of horticultural flowers is the erosion of flowers by pests and diseases. Once the flowers are infected with pests and diseases, it will bring a huge threat to the growth and survival of flowers. Therefore, the prevention and control of pests and diseases is very critical in the cultivation of horticultural flowers. part. [0003] Among the cur...

Problems solved by technology

[0003] 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.
