Abstract

The invention discloses a seed-dressing agent for reducing a herbicide residue injury and a preparation method of the seed-dressing agent, relates to a seed-dressing agent and a preparation method thereof, and aims at solving the problems that an existing product for a herbicide detoxicant is unstable in performance, unstable in pesticide effect, and not obvious in detoxifying and residue-reducing effects, and is affected by an external environment. The seed-dressing agent disclosed by the invention comprises the following raw materials by weight percent: 0.05-1.05% of 1,8-naphthalene acid, 1.5-10.8% of a biological activator, 0.05-2.15% of DA-6, 5-11.5% of a dispersant, 2-12% of a film-forming gent, 1-4% of dye, 1-3% of a defoamer and the balance being additive. The method comprises the following steps: 1 weighing raw materials; and 2 crushing and processing. The seed-dressing agent product disclosed by the invention is stable in performance, stable in pesticide effect, and obvious in detoxifying and residue-reducing effects, and is not affected by the external environment. The preparation method is applied to preparation of the seed-dressing agent.

Description

technical field [0001] The invention relates to a seed dressing agent and a preparation method thereof. Background technique [0002] The types of antidotes used to solve the problem of herbicide injury in production are relatively messy. The products are mainly used to mediate the growth and development of crops. They cannot reduce the amount of herbicide residues in the soil, and can only relieve the symptoms of phytotoxicity after the occurrence of phytotoxicity. The effect is not obvious when the phytotoxicity is serious; the herbicide protective agent can prevent the residual phytotoxicity of the herbicide on the crops and play a protective role on the crops, but most of the researchers use a single protective agent for seed soaking or seed dressing Due to the lack of dosage form research, the application of the protective agent is limited; microbial degradation bacteria agent is a better herbicide degradation agent, but microbial colonization is greatly affected by env...
