Abstract

The invention discloses a citrus young sprout contact insecticide which adopts fluoroglycofen-ethyl as an effective ingredient of the young sprout contact insecticide for plants, particularly methanol is used as a cosolvent and the fluoroglycofen-ethyl is dissolved in tetramethylbenzene, added with an emulsifier and a dispersing agent so as to form a stable emulsifiable solution with good dispersion. The invention has stable dosage form, excellent disintegration and dispersion and a simple preparation method and can form uniform solution after being dissolved in water with slightly mixing, thus providing great convenience for mechanized insecticide spraying. The contact insecticide of the invention can kill the new sprout of a fruit tree instead of manual sprout picking, thus saving labor cost for management of fruit trees and having no adverse effect on old leaves and young fruits.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a contact killer for citrus shoots. Background technique [0002] During the young fruit period of citrus, a large amount of germination of summer shoots will take away a large amount of nutrients from the tree body, which will lead to insufficient supply of nutrients for young fruits, resulting in a large number of fruit drop. Therefore, controlling the growth of new shoots in the young fruit stage of citrus is one of the key technologies of citrus management. [0003] There are two main ways to control the new shoots of citrus in production at present: one is to pick the shoots and circumcision manually, and the other is to control the shoots by spraying plant growth inhibitors. Manual picking and circumcision are inefficient and consume a lot of labor. It can be handled manually on small-area fruit trees, but if it is a large-area orchard, manual l...
