Problems solved by technology

The dry injection systemic insecticides used in recent years, such as omethoate, dichlorvos, etc., are highly toxic and highly polluting insecticides. While killing target pests, other beneficial insects, natural enemies and birds are also affected by feeding. The population density is also seriously affected by the damage or loss of the host, and there is a huge ecological risk, which brings great environmental hidden dangers

preparation example Construction

[0039] The second aspect of the present invention provides a method for preparing a dry injection solution for red pine branch pests, comprising the following steps: first dissolving the imidacloprid original drug in a cosolvent, then adding a surfactant and a penetrating agent, and then adding a solvent , adjust the pH to 5-7, stir, and obtain a homogeneous transparent liquid after standing still, that is, a dry injection liquid preparation is obtained.

[0040] The invention also includes the application of the dry injecting liquid agent to the pests of the red pine branches.

[0041] The specific method of the application is:

[0042] (1) One drill hole with a ground diameter of less than 15cm, two drill holes with a ground diameter of 15-30cm, and three drill holes with a ground diameter of more than 30cm;

[0043] (2) The drilling height is 10-50cm from the ground, preferably 20-30cm;

[0044] (3) The drilling depth should be close to the trunk tunnel core.

[0045] (4...

Embodiment 1

[0050] Example 1: 25g of imidacloprid raw powder was dissolved by adding 100ml of 20% acetic acid, then 5ml of N-ethylpyrrolidone and 2g of fast T were added, and finally the volume was adjusted to 500ml with water.

Embodiment 2

[0051] Example 2: 25g of imidacloprid raw powder was dissolved by adding 100ml of 20% hydrochloric acid, then adding 5ml of dimethyl sulfoxide and 2g of fast T, and finally distilled to 500ml with water.

Abstract

The invention relates to a trunk injection liquid agent for Japanese red pine branch trunk pests as well as a preparation method and application of the trunk injection liquid agent. The trunk injection liquid agent is prepared from the following raw materials in percentage by weight: 0.1-20% of imidacloprid, 15-25% of acetic acid, 1-10% of a surfactant, and 1-5% of a penetrating agent, with the balance being a solvent. Compared with existing trunk injection liquids, the trunk injection liquid has the characteristics of low toxicity, high efficiency, low residue, safety to human, livestock, plants and natural enemies and the like. The preparation method is simple in process, low in cost and good in plant absorption; according to the application, more than 80% of organic solvents are reduced, and the risk of environmental pollution is greatly reduced. The application is not influenced by weather and the height of the tree body, and the prevention and treatment effect is better.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of forest pests, and in particular relates to a liquid agent for injecting dry pests of red pine branches and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
