Abstract

The invention discloses a 28-homobrassinolide microcapsule suspending agent, which is prepared from the following ingredients in percentage by mass: 0.0001 to 60 percent of 28-homobrassinolide, 0.1 to 5 percent of wetting agents, 0.1 to 8 percent of dispersing agents, 1 to 6 percent of anti-freezing agents, 0.1 to 3 percent of thickening agents, 0.1 to 3 percent of antifoaming agents, 3 to 5 percent of capsule wall materials, 0.1 to 10 percent of pH conditioning agents and the balance of water. The microcapsule suspending agent is helpful for stabilizing the 28-homobrassinolide in a preparation and exerting the drug effect of the 28-homobrassinolide.

Description

technical field [0001] The invention relates to the technical field of pesticide compositions, and more specifically relates to a 28-homobrasinolide microcapsule suspension and its application. Background technique [0002] At present, my country's apple planting area is increasing, and the traditional use of 24-epi-brassinolide single-agent pesticide varieties has no obvious increase in apple yield, and the number of times of use; while 28-homobrasinolide can promote cell division and elongation, and improve Enzyme activity, improve seed vigor, promote early development, can be well used for crop nutrition, regulate crop growth, and be used to alleviate damage in freezing injury, drought, and phytotoxicity. 28-Homobrassinolide is one of the steroidal compounds with higher biological activity, and they are widely present in plants. In each stage of plant growth and development, it can not only promote vegetative growth, but also facilitate fertilization. The artificially sy...
