Embodiment 1-21

[0015] A thiadiuron oil suspension comprises thiadiuron, vegetable oil, dispersant, thickener, emulsifier and stabilizer.

[0016] The weight percentage content of above-mentioned each material is as follows:

[0017]

[0018]

[0019] The preparation method of the above-mentioned thiadizuron oil suspension is as follows: add the vegetable oil into the reaction kettle and start stirring, then put in thiadizuron, dispersant, emulsifier, thickener in turn, stir evenly, add stabilizer to the sand mill for grinding , until the particle size is within 5 microns.

[0020] The above-mentioned ratio of thiadidiuron oil-suspending agent was tested in the experimental field of the 121 regiment agricultural technology station. The cotton variety was Xinluzao No. 30, and 20 g of thiadidiuron oil-suspending agent was used per mu, dissolved in 40 kilograms of water. Spraying time is September 16.

[0021] The number of leaves, bolls and flocculation of cotton were investigated befor...

Abstract

The invention discloses a thidiazuron suspension agent which is applied for disleaving and accelerating maturation for cotton in the later period. The thidiazuron suspension agent comprises the following components in percentage by weight: 1-60% of thidiazuron, 30-80% of vegetable oil, 3-10% of dispersant, 0.5-8% of thickening agent, 4.5-15% of emulsifier and 2-10% of stabilizer. The thidiazuron suspension agent is processed by taking the thidiazuron as an active ingredient and the vegetable oil as a synergism ingredient, thus the use effect of the thidiazuron and the osmosis of thidiazuron on lamina are greatly improved, the retention time of effective ingredients on the lamina is prolonged, the pesticide use amount is lowered, the dust pollution is reduced, and the thidiazuron suspension agent provided by the invention is convenient to transport and apply.

Description

technical field [0001] The invention relates to a pesticide, in particular to a thiadizuron oil suspension for regulating plant growth. Background technique [0002] Thidiazuron is a new type of high-efficiency cytokinin. It is sprayed and used in the later stage of cotton growth. After being absorbed by the leaves, it is transmitted to the petiole, which can promote the formation of the separation tissue between the petiole and the stem and make the leaves fall off. It is a good defoliation of cotton. Ripening agent. At present, the thiadizuron preparations developed in China are all wettable powders, which will cause dust pollution during processing and are not easy to weigh when used. In recent years, the state requires the development of environmentally friendly new pesticide dosage forms, and develops in the direction of water-based, ultra-micronized, dust-free and controlled-release. Contents of the invention [0003] The technical problem to be solved in the prese...
