Problems solved by technology

In southern paddy fields, such as Wuhan, Spirogyra is common in paddy fields, covering the water surface and sinking to the bottom of the water. Its large-scale occurrence will lead to poor growth of rice seedlings, lower water temperature, resulting in reduced tillering, and finally affect yield.

preparation example Construction

[0041] A method for preparing compound granules containing triphenyltin acetate and siclozin, the method steps are as follows:

[0042] Step 1: Prepare functional master powder or mother liquor of phase A components;

[0043] Step 2: determining suitable carrier particles and their carrier physical indicators;

[0044] Step 3: making granules by dry method or making granules by wet method;

[0045] Step 4: Prepare the finished product.

[0046] Moreover, the method for preparing the A-phase functional mother powder includes: first mechanically pulverizing or airflow pulverizing the active ingredient original drug to obtain the original drug fine powder with a particle size of 300-350 mesh, and then taking the active ingredient original drug fine powder by weight ratio 5 %-90%, binder 0.5%-10%, water reducer 0.5%-10%, dispersant 0.1%-5%, wetting agent 0.1%-5%, placed in a gravity-free mixer for weight loss mixing, Obtain the functional mother powder for later use.

Abstract

The invention relates to a compound granule containing triphenyltin acetate and simetryn and a preparation method and application of the compound granule. The granule comprises functional mother powder of A-phase pesticide active ingredients, namely 0.1-40% of triphenyltin acetate, and 0.1-40% of simetryn; a phase B component: 60%-95% of a natural quartz sand carrier, an artificially roasted particle carrier and a plant-derived crushed particle carrier; and a phase C component: 0.2%-50% of functional bonding slurry, which comprises an inducer, a binder and a warning color. The granule is scientific and reasonable in design, the granule capable of being used for preventing and removing rice aquatic weeds is prepared from the natural quartz sand carrier, the artificially roasted particle carrier and the plant-derived crushed particle carrier through a coating film-forming method, the two raw medicines have high prevention and treatment effects on the aquatic weeds in the paddy field, andcompared with other dosage forms of the product in the market, the granule is low in pollution, more environment-friendly, more environment-friendly in production process, good in product stability,and more convenient and simpler in transportation and use.

Description

technical field [0001] The invention belongs to the field of chemical pesticide production and relates to compound granule technology, in particular to a compound granule containing triphenyltin acetate and siclozin and its preparation method and application. Background technique [0002] In the process of rice planting in my country, rice will face the threat of various diseases, insect pests and weeds during the whole growth period. Serious diseases, insect pests and weeds will directly or indirectly affect the growth and development of rice, which will cause unpredictable changes in the final rice yield. loss. The use of chemical pesticides will ensure the high yield of rice by controlling diseases, insect pests and weeds, but unreasonable pesticide formulations will seriously pollute the environment and cause a waste of resources. Therefore, safe, efficient, time-saving and labor-saving pesticide dosage forms have emerged, and dosage forms such as granular, water-based, ...
