Abstract

The invention relates to a preparation system and application of a controlled-release pesticide suspending agent for preventing and treating kaffir lily leaf spot. The controlled-release pesticide suspending agent is prepared from the following components in parts by weight: 20-40 parts of composite nano porous carbon particles, 5-8 parts of polyethylene glycol, 2-5 parts of sorbitol, 2-5 parts ofxanthan gum, 0.1-0.5 part of propyl p-hydroxybenzoate, 5-8 parts of soluble starch and 30-50 parts of deionized water. The controlled-release pesticide suspending agent prepared by the invention is suitable for preventing and treating kaffir lily leaf spot and scale insects, and has the advantages of double killing, thorough killing, long acting time and small environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a preparation system and application of a controlled-release pesticide suspension for preventing and treating Clivia leaf spot. Background technique [0002] Clivia, also known as sword-leaf Lycoris and large-leaf Lycoris, is a perennial herbaceous plant of the genus Clivia in the Amaryllidaceae family. It is an ornamental flower and is native to southern South Africa. The flowering period is as long as 30-50 days, mainly in winter and spring. It also blooms from New Year's Day to Spring Festival. It avoids strong light. It is a semi-negative plant. It likes coolness and avoids high temperature. Clivia has high ornamental value and is often potted in greenhouses in China. Ornamental. Its varieties include Clivia grandis, Smiling Clivia, Thin-leaf Clivia, Yellow Clivia, etc., which are cultivated in greenhouses in various places and have various colors. However, t...
