Problems solved by technology

The traditional control of pine xylophilus is to spray pesticides on the outside of the tree, it is difficult to kill the pine xylophilus in the xylem of the trunk
[0006] The pine wood nematode is transmitted by the adult pine wood monochamus, and the larvae of the pine wood monochamus are borer pests. They feed on the pine woody tissue and

Abstract

The invention discloses a preparation method for a trunk injecting microcapsule pesticide for controlling Bursaphelenchus xylophilus and aims to prepare a pesticide capable of controlling occurrence of the Bursaphelenchus xylophilus. A microcapsule technology is adopted to compound a chitinase inhibitor pesticide with an abamectin biopesticide, and the preparation method comprises the specific flow as follows: (1) the chitinase inhibitor pesticide is ground with diesel oil as an assistant, and ointment is prepared; (2) the biopesticide is dissolved with a solvent and mixed with the ointment, and the mixture is stirred uniformly; a synergist, a surfactant and water are added, the materials are heated and stirred to be emulsified and dispersed, and an emulsion is prepared; (3) a wall material aqueous solution is added to the emulsion and stirred at the constant temperature of 55-65 DEG C, a microcapsule forming reaction is performed, a product is cooled after the reaction, and the trunk injecting microcapsule pesticide is prepared. The pesticide prepared with the method can kill the Bursaphelenchus xylophilus and larvae of monochamus alternatus. The period of validity of the pesticide in a trunk can be 2 years or longer, and the Bursaphelenchus xylophilus killing rate can be 100%.

Description

technical field [0001] The invention belongs to the field of pesticide manufacturing in the chemical industry, and in particular relates to a method for manufacturing a microcapsule injection-dried pesticide for preventing and treating pine wood nematode disease. Background technique [0002] Pine wood nematode disease in my country was introduced from Japan. It was first discovered in Nanjing in the 1980s. Later, it spread rapidly along the Yangtze River Basin. In recent years, epidemic areas have been found in all provinces south of the Yellow River in my country. Dead within ten days, pine xylophilus is spread by coleopteran pests such as monochamus alternatus, which is a devastating major forestry natural disaster. [0003] The peak period of adult eclosion of Monochamus alternatus is from May to August. Before the monochamus alternatus pupates and emerges, there are a large number of pine wood nematodes parasitizing in the respiratory tract. During the spawning process ...
