Embodiment 1

[0010] The tree body injection includes the following components: 10% imidacloprid wettable powder 8.5g, 95.5% medical alcohol 11ML, the balance is water, configured into a 50mL solution, and divided into 10 parts, aiming at the diameter of Platanus 30cm, using an electric drill with a 5.2mm drill bit Vertically drill holes 10-20cm below the first-level branch point of the main trunk, the hole depth is 2.5-3.5cm, one hole every 10-15cm, circle around the tree, the dosage is 5ml / hole, and pulse injection with an injection machine. After experiments, Platanus The pest control rate of square-winged net bugs is 86%, and the damage to trees is 0.

Embodiment 2

[0012] The tree body injection includes the following components: 10% imidacloprid wettable powder 10g, 95.5% medical alcohol 10ML, the rest is water, configured into a 50mL solution, and divided into 10 parts, aiming at the diameter of Platanus 30cm, using an electric drill with a 5.2mm drill bit on the trunk Vertically drill holes 10-20cm below the first-level branch point, the hole depth is 2.5-3.5cm, one hole every 10-15cm, circle around the tree, the dosage is 5ml / hole, inject the drug with an injection machine pulse, after the experiment, the plantain square The rate of extermination of stinkbugs is 91%, and the damage to trees is 0.

Embodiment 3

[0014] The tree body injection includes the following components: 10% imidacloprid wettable powder 10.5g, 95.5% medical alcohol 9ML, the balance is water, configured into a 50mL solution, and divided into 10 parts, aiming at the 30cm diameter of the plane tree, using an electric drill with a 5.2mm drill bit Vertically drill holes 10-20cm below the first-level branch point of the main trunk, the hole depth is 2.5-3.5cm, one hole every 10-15cm, circle around the tree, the dosage is 5ml / hole, and pulse injection with an injection machine. After experiments, Platanus The pest control rate of square-winged net bugs is 93%, and the damage to trees is 3%.

Abstract

The invention relates to a pesticide, in particular to a tree pesticide injection which is prepared from, by weight, 3.75-5% of imidacloprid, 2-80% of volatile transmitter and the balance water. The tree pesticide injection has the advantages that the formula is fixed and simplified, the most proper matching concentration is found, the tree pesticide injection can be used by being prepared by workers on site, prevention cost is reduced by 50% or above, the problem that bark cracks is solved, and tree damage is reduced.

Description

technical field [0001] The invention relates to an insecticide, in particular to a tree insecticide injection. Background technique [0002] Under the new application method, the medicament has no pollution to the environment, and the insecticidal effect is long, which is the characteristic of the tree body injection. In the past 20 years, the research on direct injection of tree body injections to plant cadres has developed rapidly. Currently, the existing tree body injections on the market are one or two kinds of pesticides, solutions, emulsifiers (a small amount or no addition) and other auxiliaries. It is a single-item transparent liquid that is mixed and processed in a certain proportion. It can be used directly without dilution. It is suitable for the prevention and treatment of insect pests with piercing-sucking mouthparts on leaves and branches, but it is very easy to cause phytotoxicity, such as a large area of ​​trunk at the injection site. Cracking, used on eucal...
