Problems solved by technology

[0007] Cotton blight and Verticillium wilt are one of the serious diseases of cotton that are very difficult to control, causing huge economic losses to cotton production every year, especially the transgenic insect-resistant cotton, which has a high incidence
Because Verticillium dahliae invades the vascular bundles of cotton plants, general pesticides cannot enter the vascular bundles to kill the pathogens, so there are no effective control methods and pesticides at home and abroad.

Abstract

The invention discloses a seed coating agent for resisting cotton pollenosis, whose essential components include natural abscisic acid and strong bacillus, the pesticide has prevention effect for cotton sprout damping-off disease, carbon anthrax and other mycosis.

Description

[0001] 1. Field [0002] The invention belongs to a kind of agricultural pesticide, in particular to a seed coating agent made of natural abscisic acid and Bacillus firmus. 2. Background technology [0003] Natural 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 [0004] [0005] 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 activity of plants. Studies have shown that abscisic acid is the "stress-resistance inducing factor" and "balanced growth factor" of plants, which can initiate the expression of plant stress-resistant genes, activate the plant's endogenou...
