Composition for controlling crop pests, preparation method and application thereof

Abstract

The invention relates to the technical field of crop pests controlling technology, and particularly relates to a composition for controlling invertebrate crop pests such as snails or the like, and a preparation method and an application thereof. The composition for controlling crop pests comprises carboxymethylcellulose sodium and blue vitriol and is used for controlling snail type pests. Compared with the prior art, the composition has a synergistic effect of the carboxymethylcellulose sodium and the blue vitriol on the contacted snail type pests, so that the snail type pests are prevented from continued creeping and harming related crops by means of stimulation on their sense organs, and other parts of the crops is [are] prevented from being polluted by insecticides. Furthermore, the composition can be effectively prevented from being washed by rainwater, and thereby a stable and lasting controlling effect can be maintained. A green and environment-friendly type pest-preventing operation is achieved without any safety hidden trouble.

Description

Technical field [0001] The invention relates to the technical field of crop pest control, in particular to a composition for preventing and controlling invertebrate crop pests such as snails, a preparation method and application thereof. Background technique [0002] There are many kinds of snails, including about 25,000 kinds of snails and slugs of the same type. Snails are hermaphroditic and allogeneic, and both sexes lay eggs. Snails have a high reproductive rate. Each snail can lay eggs 6 to 7 times a year, with an average of 200 eggs each time. Snails live in grasses, bushes, tree trunks, farmland, and dark and humid areas near houses. They mainly feed on plant stems, leaves, flowers, fruits, and roots. They harm crops and are one of agricultural pests. They are also intermediate hosts of certain parasites in livestock and poultry. . The following is a brief introduction with slugs and snails of the same type as examples. [0003] Slug (Slug), commonly known as slug, is al...

Problems solved by technology

[0006] Among the chemical control methods of the above-mentioned various snails, it is generally to directly spray the place where the snails are located, to kill and remove the snails as the direct purpose, and the duration of the relevant crops is short, especially for crops such as fruit trees. It is difficult to achieve the effect of comprehensive removal of snails during control, and it will cause pollution to flowers, fruits, etc.
