Plant growth regulating composition capable of preventing seed ear from sprouting

Abstract

The present invention provides a plant growth regulator coposition comprising natural abscisic acid, sulfur maturing agent and at least a kind of herbicide as its active components except inert processing assistant.

Description

technical field [0001] The invention relates to a plant growth regulating composition containing natural abscisic acid capable of inhibiting ear germination, and the international classification number belongs to A01N37 / 06. Background technique [0002] Natural abscisic acid, S-Abscisic acid (S-ABA), common name of pesticide: S-abscisin. Molecular formula: C 15 h 20 o 4 , the chemical name is: 5-(1'-hydroxy-2',6',6'-trimethyl-4'-oxo-2'-cyclohexen-1'-yl)-3-methyl- 2-cis-4-trans-pentadienoic acid, the chemical structure is as follows [0003] Chemical structure of S-ABA [0004] In 1963, abscisic acid was first extracted from young cotton fruit by Addicott et al. For more than 30 years, scientists from various countries have conducted extensive and in-depth research on the physiological activities of plants. Studies have shown that abscisic acid is the "stress-resistance inducing factor" and "balanced growth factor" of plants, and it can initiate t...

Problems solved by technology

At present, there are no effective prevention methods and control measures, which bring great losses to the seed industry every year.

In the milky or yellow ripening stage of cereal crops, although S-ABA (70-200ppm) alone can be used to prevent grain ear buds of gramineous plants, such as hybrid rice ear germination and wheat ear germination, the amount of S-ABA is too large. High cost of agricultural production
