Abstract

The invention discloses plant ecological pesticide and a preparation method thereof and belongs to the technical field of pesticide. The plant ecological pesticide is prepared from the following raw materials in parts by weight: 5 to 15 parts of xanthium strumarium herb, 10 to 20 parts of tripterygium wilfordii, 5 to 15 parts of Chinese ephedra herb, 10 to 20 parts of fructus forsythiae, 10 to 20parts of herba taraxaci, 10 to 20 parts of rhizoma pinelliae and 5 to 15 parts of radix pulsatillae. The plant ecological pesticide disclosed by the invention has no harm and no side effect on human bodies and also has an efficient insecticidal effect; the plant ecological pesticide has no pollution to the environment and no residues and has good economic value and social value.

Description

Technical field [0001] The invention relates to a plant ecological pesticide and a preparation method thereof, and belongs to the technical field of pesticides. Background technique [0002] Pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used are DDT, BHC, etc., which can eliminate pests in large quantities. But they have good stability, can exist in the environment for a long time, and accumulate in animals, plants and human body, so they are eliminated. Later, organic phosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. In recent years, a batch of high-efficiency and low-toxic pesticides have appeared. Now people have found specific pesticides, namely hormone pesticides. The pesticide residues used by people nowadays are harmful to crops. The raw materials of the present invention h...
