Plant growth regulator preparation technology

Abstract

The invention relates to a plant growth regulator preparation technology, in particular to a paclobutrazol suspending agent and a preparation technology thereof, is suitable for the pesticide preparation preparing technology and belongs to the technical field of chemicals. In China, paclobutrazol is oriented to the market mainly in the form of 15% wettable powder. Due to the fact that the wettable powder is prone to dust pollution in the processing and using processes and the suspending rate of the wettable powder is lower than that of a suspending agent, products are prone to phytotoxicity. A paclobutrazol technical material, a wetting agent, a dispersing agent, a thickening agent, an antifoaming agent, an antifreezing agent, a preservative and other substances are adopted and prepared into the paclobutrazol suspending agent according to a certain weight percentage through a specific preparation method. The paclobutrazol suspending agent has the advantages of being capable of being uniformly mixed with water in any proportion and dispersed, good in fluidity, free of influences of water quality and water temperature, convenient to use, not prone to environmental pollution and capable of being sprayed directly or after dilution.

Description

technical field [0001] The invention relates to a production technology of a plant growth regulator, in particular to a paclobutrazol suspending agent and the production technology thereof, belonging to the technical field of chemical industry. Background technique [0002] Pesticide suspension is a pesticide dosage form prepared by wet ultrafine grinding of water-insoluble solid pesticides, pesticide adjuvants (wetting agents, dispersants, thickeners, defoamers, antifreeze agents, preservatives, etc.) and water. The advantage of this dosage form is that it can be uniformly mixed and dispersed with water in any proportion, not affected by water quality and water temperature, easy to use, not easy to pollute the environment, and an ideal dosage form that can be sprayed directly or after dilution. Suspending concentrate is a new "environmentally friendly" dosage form recognized by the pesticide industry at home and abroad. The development of this dosage form has created a bro...
