Problems solved by technology

In some areas, fumigants are often used to achieve total kill, but fumigants are time-consuming and costly to use
[0004] At present, there are also some botanical pesticides on the market. Due to many reasons such as single ingredients, poor control effect, short duration of effect, and long safety interval, they have not been widely promoted in practical applications.
What's more, in order to achieve a better insecticidal effect and increase production, some areas illegally use highly toxic insecticides banned by the state, causing poisonous vegetables, melons and fruits to occur from time to time, causing great harm to consumers

Abstract

The invention discloses a plant-based agricultural insecticide. The plant-based agricultural insecticide is characterized in that raw materials are prepared from multiple plant-based medicines. Compared with the prior art, the plant-based agricultural insecticide has the high killing rate, the long lasting period and the short safety interval, and can ensure the high agricultural product yield, and agricultural products can be safe and non-toxic.

Description

technical field [0001] The invention relates to the field of biological insecticide, in particular to a plant-source agricultural insecticide for the control of agricultural pests, especially underground pests, with low toxicity, safety, high efficiency, long duration and short safety interval, and a preparation method thereof. Background technique [0002] The control of agricultural pests is an important part of high yield and income increase in agricultural production, especially the pollution-free control of underground pests has always been the focus of attention of the agricultural plant protection industry. longing. [0003] The types of underground pests mainly include: nematodes, grubs, cutworms, needleworms and some flies and mosquito larvae, namely various ground maggots. The insecticides allowed to be used in the control of these pests are chemically synthesized pesticides avermectin, phoxim, chlorpyrifos, thiazophos, and a small amount of products such as matri...
