Problems solved by technology

[0003] Emamectin benzoate, full name emamectin benzoate, the original drug is white or light yellow crystalline powder, is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized based on abamectin B1, with super high efficiency, Low toxicity, low residue and other characteristics, so it can be used as an effective drug for preventing pine wood nematodes, but its solubility in water is poor, and when it is prepared with water as a solvent for environmental protection, it will have poor stability. Difficult to preserve for a long time

Abstract

The invention discloses an emamectin benzoate pesticide for preventing Bursaphelenchus xylophilus. The preparation raw material comprises: 1.5-2.5 wt% of emamectin benzoate, 5-20wt% of compound containing oxyethylene group, 5-57wt% of monohydric alcohol with 1-6 carbon atoms, 0.1-0.5 wt% of thickener, 2-20wt% of alcohol ether compound and the balance of water. The emamectin benzoate pesticide agent has excellent stability through reasonable composition, and the extremely fine particle size ensures that the agent can be stored for a long time. The efficacy test proves that the agent has remarkable effect on preventing Bursaphelenchus xylophilus and has broad development prospects.

Description

technical field [0001] The invention relates to the field of agrochemicals, in particular to an emamectin benzoate pesticide medicament for preventing pine wood nematodes. Background technique [0002] Pine wilt, also known as pine blight, is a devastating pest. It is mainly transmitted in the pine tree through vector insects such as the pine tree nematode, thereby causing pine tree diseases. After being infected by the pine wood nematode, the needles of the pine tree are yellowish brown or reddish brown, wilting and drooping, the resin secretion stops, and the trunk can be observed. Invasion holes or traces of spawning, the whole plant of the diseased tree withers and dies, and eventually rots. Most species in the genus Pinus are tall and straight trees with good materials, and are widely used in industries, constructions, households and other fields. They also have ornamental value, so they are extremely important for the prevention of pine xylophilus. [0003] Emamectin...
