Problems solved by technology

In addition, these silicas also have a large specific surface area, strong adhesion and adsorption capacity, and strong adsorption capacity for wax on the body wall of pests, making the wax layer and wax protection layer of the epidermis on the body wall of pests A certain degree of damage will directly cause the loss of water in the pest body to accelerate, causing the death of the pest
However, this silicon dioxide anti-caking agent is used as an insecticide, it is difficult to stay on the plant surface for a long time, and the time for spraying insects is shorter, and the cost of long-term application in garden insecticide is higher

Description

technical field [0001] The invention relates to the field of garden insecticides, in particular to an environmentally friendly and low-irritation garden insecticide and a preparation method thereof. Background technique [0002] With the development of the economy, people's living standards are improving day by day, and higher requirements are put forward for the greening of the living environment. Therefore, in recent years, when designing, a certain area of ​​gardens or lawns is often planned. However, gardens or lawns will inevitably attract various insects during the growth process, and various measures need to be taken to kill or repel insects. At present, there is no special insecticide designed for gardens in residential areas. People usually use agricultural insecticides directly to kill insects in residential gardens. However, agricultural insecticides are highly toxic and irritating, which will threaten the health of the majority of residents. healthy. [0003] C...
