Abstract

The invention discloses a pesticide prepared from Chinese herbal medicines, which relates to a pesticide for a greenbelt in a city and belongs to the field of pesticides. The pesticide is characterized by comprising the following raw materials, by weight, 0.5 to 10% of emamectin benzoate, 3 to 25% of algae, 1 to 12% of a surfactant, 1 to 8% of an easily degradable polymer, 2 to 15% of a stabilizing agent, 2 to 15% of a plant-growth regulator, 5 to 45% of Kaempferitrin, 8 to 25% of cedrol and 6.5 to 20% of sapogenin. The invention has the following beneficial effects: the raw materials for the biological pesticide are algae and extracts of wild Chinese herbal medicines, so the biological pesticide does not contain chemical components harmful to human bodies, which enables landscape trees applied with the pesticide not to contain residual substances harmful to human bodies; a preparation method for the biological pesticide is simple, has low cost and is convenient for popularization and application; the raw materials are easily available, processing technology is simple, cost is low, and the pesticide is suitable for industrial large-scale production and has a wide application scope.

Description

technical field [0001] The invention relates to an insecticide for urban green belts, which belongs to the field of insecticides, in particular to an insecticide made of Chinese herbal medicine. Background technique [0002] Today, when advocating green and protecting the environment, many highly toxic and high residue chemicals have been limited or discontinued. Organophosphorus, organic amines, pyrethroids, benzoyl ureas, and biochemical pesticides have been compounded and combined to reduce the original toxicity to a certain extent. The reagent dilution of agricultural insecticides has far exceeded its limited range, and the chemical residues of agricultural products are far from meeting the requirements of pollution-free. The increasing demand for pesticides has caused the aggravation of rural environmental pollution, and its residues are harmful to the human body. It cannot be ignored. [0003] The main insect pests of greening trees include longicorns, psyllids, leaf...
