Problems solved by technology

[0004] 1. Acute poisoning
[0005] 2. Chronic hazards
[0006] 3. Carcinogenic, teratogenic, mutagenic
[0007] 4. The harm of herbicides to other organisms
[0010] Bioaccumulation of traditional chemical herbicides is the most serious form of pesticide indirect harm to organisms. Herbicides in plants can pass through the food chain and accumulate continuously, posing potential threats to humans and animals and affecting ecosystems.

Abstract

The invention discloses a biogenic herbicide which is characterized by being prepared from, by mass, 15-25 parts of artemisia scoparia, 10-15 parts of fragrant eupatorium herb, 10-20 parts of coptis chinensis, 10-20 parts of melia azedarach bark, 15-25 parts of celastrus angulatus, 10-20 parts of dicranopteris pedata, 20-30 parts of lemons, 10-20 parts of green plums and 1-3 parts of a penetrating agent.The materials are smashed, extracted, mixed and purified to prepare the biogenic herbicide.The biogenic herbicide is good in drug type.Through medicine effect comparison, the biogenic herbicide has a better prevention effect than a traditional herbicide and is free of toxin and harm, little in environment pollution and capable of effectively guaranteeing safety of crops, and accordingly it is guaranteed that people and animals cannot be harmed by absorbing chemical matter from the crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, relates to the technical field of herbicides, in particular to a biological herbicide and a preparation method thereof. Background technique [0002] Herbicides, also known as herbicides, refer to agents that can completely or selectively kill weeds. Sodium chlorate, borax, arsenic acid, trichloroacetic acid have a deadly effect on any kind of vegetation, but because of their residual effects, they should not be used in the field. Selective herbicides, especially derivatives of nitrophenols, chlorophenols, and carbamic acids, are mostly effective. [0003] There are many kinds of herbicides, such as paraquat, glyphosate, and acetochlor. The ingredients of each are slightly different, but the main ingredients are uranium chlorate, shed sand, limestone, and trichloroacetic acid. But here These ingredients have a deadly effect on any kind of plant, but because these have residual effects, they ...
