Problems solved by technology

[0011] In agricultural production, the production and consumption of plant growth regulators are increasing year by year. Although the regulation effect of a single plant growth regulator on some crop fields is very good, due to the narrow application of a single plant growth regulator, crops Strong selectivity, severe drug residues and only regulates crop growth, cannot achieve the effect of both disease resistance and growth regulation

Embodiment 1

[0094] Example 1: 30% Methiamin Brassinolide Suspension Concentrate (2:1)

[0095] Components: Methiamin 20%, Brassinolide 10%, Sodium Lignosulfonate 8%, Nongru 600# 3%, Fatty Alcohol Polyoxyethylene Ether 3%, Water supplement.

[0096] Preparation method: Weigh the formula components according to the proportion, stir and mix them thoroughly, then grind them to a fineness of 1-4 microns, and then mix them again to prepare 30% formosan brassinolide suspending agent .

Embodiment 2

[0097] Embodiment 2: 55% thiaminamide brassinolide water dispersible granules (10:1)

[0098] Components: Methiamin 50%, Brassinolide 5%, Cyclohexanone 13%, Lignosulfonate 3.5%, Nongru 400# 3%, Glycol Ether 2%, Silica Gel 3%, Bentonite supplement.

[0099] Preparation method: first dissolve the original drug completely with a solvent, then add wetting agent, disintegrating agent and other additives and grind in water to obtain particles with a particle size of 150-200 μm, and then dry and sieve to obtain 55% methylthiophene Luminamine Brassinolide water dispersible granules.

Embodiment 3

[0100] Embodiment 3: 51% thiaminamide · brassinolide emulsion in water (50:1)

[0101] Components: Methiamin 50%, Brassinolide 1%, Calcium Lauryl Sulfate 2.5%, Nongru 1601# 3.3%, Nongru BY125 4%, Cyclohexanone 10%, Glycerol 3 %, nonpolyphenol polyoxyethylene ether 3%, water supplement.

[0102] Preparation method: Dissolve the original drug completely with a solvent, add wetting dispersant and water into a shearing machine for shearing and mixing, and obtain 51% methyltimidobrassinolide aqueous emulsion.

Abstract

The invention provides a pesticide composition and application thereof, belonging to the technical field of mixed pesticides. The pesticide composition comprises an active component A and an active component B, wherein the active component A is methiadinil, the active component B is a plant growth regulator, and a weight ratio of the active component A to the active component B is in a range of 2: 1 to 2500: 1, preferably 10: 1 to 1000: 1. The plant growth regulator B may be uniconazole, brassinolide, indolebutyric acid, compound sodium, nitrophenolate, butralin, or the like. Compounding of the active component A and the active component B exerts obvious synergistic effect, and the respective application amounts of the active component A and the active component are reduced. Any dosage form of the composition can be prepared by adding auxiliary components acceptable in other pesticides. The pesticide composition provided by the invention is mainly applicable to crops like paddy rice, corn and rape, and can induce the crops to generate systematic disease resistance, effectively control pathogenic fungi of plants, prevent and treat a plurality of diseases like tomato virus diseases, wheat powdery mildew, sclerotinia rot of colza, cabbage clubroot, rice blast, wheat sharp eyespot and grape downy mildew, and regulate plant growth to realize yield increase of the crops.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a pesticide composition, in particular to a pesticide composition containing thiamin and a plant growth regulator and its application. Background technique [0002] In agricultural production, pesticides have played a huge role in increasing production and income, but unscientific and single use of pesticides, as well as frequent use of pesticides also increase the economic burden, and lead to a series of serious ecological problems and environmental pollution and agricultural product safety. social problem. Therefore, how to use scientifically, reduce the amount of chemical pesticides, and improve the efficacy has become an urgent issue in the field of plant protection. [0003] Thiadiazole (SZG) is a thiadiazole plant disease prevention activator and inducer jointly developed by Lier Chemical Co., Ltd. and Nankai University. The common chemical name is N-(5-methyl-1 ...
