[0158] Preparation of the seed treatment composition of the present invention

[0159] The following general procedure was used to prepare samples of the polymer-coated active ingredients fluvaxam and neonicotinoids, wherein the ingredients and amounts are listed in Table 1. Air mill the industrial products of flufenoxam and neonicotinoids to an average particle size of 2.0-3.0um (d50), and then disperse the active ingredients into an aqueous solution with the help of surfactants; coat the polymer Added to the aforementioned aqueous solution; these were mixed with a mixer with a dispersing blade at 2000 rpm. After everything had been well dispersed, the mixture was transferred to a homogenizer and homogenized at 6000 rpm for 20 minutes. The homogenized mixture is then spray-dried in a spray dryer to obtain a polymer-coated dry solid containing pyraclostrobin and a neonicotinoid compound. Kaolin is then added to the dry solid to obtain the seed treatment composition of the pr...

Abstract

The invention provides a seed treatment combination which comprises an active ingredient-sedaxane and a new nicotine compound and further comprises coating polymer coating the active ingredient. The coating polymer is selected from one or multiple of maltodextrin, methylcellulose, ethylcellulose, hydroxyl propyl cellulose, carboxyl propyl / methyl cellulose, and the new nicotine compound is selectedfrom one of imidacloprid, thizmethoxam, thiacloprid and clothianidin. The invention further provides a method for increasing germination rate of seeds treated by a seed treatment agent, improving plant health and protecting the seeds from being invaded by plant pathogenic fungi and harmful organisms.

Description

technical field [0001] The present invention relates to a seed treatment composition. The present invention also relates to methods of increasing the germination rate of seeds treated with a seed treatment composition, improving plant health and protecting seeds from attack by phytopathogenic fungi and harmful organisms. Background technique [0002] Seeds and seedlings are vulnerable to damage and infection by various underground and above-ground pests and pathogenic bacteria, and are the most vulnerable link in the growth process of crops; seeds and seedlings are eaten by pests, or infected by pathogenic bacteria, and diseased seedlings and dead seedlings appear. It will reduce the effective number of crops per unit area, resulting in a large-scale reduction in yield and quality of crops. [0003] The protection of seeds and germinating plants against attack by phytopathogenic fungi and pests by treating seeds with seed treatment compositions has been known for a long tim...
