Abstract

The invention provides a tree trunk injection liquid containing emamectin benzoate and thiacloprid, and a preparation method thereof. The tree trunk injection liquid comprises, by mass, 2-10% of emamectin benzoate, 2-10% of thiacloprid, 3-15% of a surfactant, 2-6% of glacial acetic acid and 59-90% of an alcoholic solvent. The trunk injection liquid has the characteristics of small dosage, low cost, high control effect, only taking effect on target pests of trees, no damage to natural enemy insects, environmental protection, wide application range, simple and convenient operation, and high work efficiency, is unlimited by geographical conditions and climate change, can be applied in an anhydrous non-contact manner, is safe to human and environment, and can pertinently control pests in forests, urban landscapes, scenic area greening trees, street trees, shelter belts and fruit trees.

Description

technical field [0001] The invention relates to the technical field of tree pest control, in particular to a dry injecting liquid for trees containing emamectin benzoate and thiacloprid and a preparation method thereof. Background technique [0002] Carry out pesticide application with injection dry method, rely on the independent conduction of medicament in several trees to prevent and treat tree diseases and insect pests method as far back as 1926, the United States has carried out practical application and developed tree injection machine. As a method of using pesticides, it has always been valued by people because of its characteristics of less pesticide application, high control efficiency, environmental friendliness, and safety for humans and animals. Tree pests and diseases, especially borer pests and branch diseases, have very little control effect with conventional spraying methods, and the occurrence and spread of such pests cannot be controlled.
