Embodiment 1

[0015] Mix imidacloprid with abamectin or dichlorvos or nicotine or quinthion or monosultap or acetamiprid respectively to form a dry injection preparation containing imidacloprid, wherein imidacloprid is 1-6% (mass ratio), and other 0.15-14% (mass ratio) of various pesticides, 1-10% (mass ratio) of surfactants known in the art, and the rest being solvents. The solvent is a mixture of tetrahydrofurfuryl alcohol and dimethyl sulfoxide or tetrahydrofurfuryl alcohol and dimethylformamide, and the mass percentage of each substance in the mixture is: 0.1% to 20% of dimethyl sulfoxide or dimethylformamide, and the rest For tetrahydrofurfuryl alcohol. Compared with the insecticides prepared with acetone and simple substances such as imidacloprid, abamectin, dichlorvos, nicotine, quinathion, monosultap, and acetamiprid, the results were obtained from the pollution-free pesticide research service center of Northwest Agriculture and Forestry University. The cotton aphid provided by the...

Abstract

The invention discloses a liquid formulation containing imidacloprid for trunk injection, which comprises (by weight ratio) the following raw materials, imidacloprid 1.0-8.0%, insecticidal agent 0.01-15.0%, surface active agent 1-10%, and balancing solvent. The agent is applied mainly through dry injection method and can be use for controlling various insects on trees.

Description

technical field [0001] The invention relates to a pesticide, in particular to an imidacloprid-containing dry injection agent for trees. The dry injection agent is mainly applied by a dry injection method and is used for the prevention and control of various pests on trees. Background technique [0002] The idea of ​​spraying pesticides by dry injection and relying on the conduction of pesticides in trees to prevent and control tree diseases and insect pests was gradually formed as early as 1200 AD. The characteristics of high efficiency, no pollution to the environment, and safety to people and animals have always been valued by people. In recent years, the occurrence of tree diseases and insect pests has become more and more serious, especially the rampant occurrence of borer pests such as longhorn beetles and chitins, which have destroyed the "Three North" shelterbelts at once, causing economic losses and ecological damage that cannot be estimated. ...
