Problems solved by technology

However, what appear on the market in my country now are mainly pesticide large granules, effervescent tablets, large granules, effervescent tablets and water-surface floating water-dispersible granules. After the tablet is thrown into the water surface, it immediately sinks to the bottom of the water, disintegrates in situ, spreads, and the speed is slow, and the particles contact the soil layer, so disintegration is easily affected, and phytotoxicity is prone to occur

Embodiment 1

[0020] Example 1: A water-dispersible granule of pesticides floating on the surface of rice fields, including active ingredients of pesticides and water surface expanders, disintegrants, polymer dispersants, binders, wetting agents, adsorbents, and carriers with a specific gravity lower than water The core material, wherein the weight percentage of each component in the composition is: 10% of the active ingredients of the pesticide, 40% of the water surface expanding agent, 5% of the disintegrant, 20% of the adsorbent, 5% of the wetting agent, and 5% of the binder %, polymer dispersant 5%, carrier core material 30%.

Embodiment 2

[0021] Example 2: A water-dispersible granule of pesticides floating on the water surface in paddy fields, including active ingredients of pesticides and water surface expanders, disintegrants, polymer dispersants, binders, wetting agents, adsorbents, and carriers with a specific gravity lower than water The core material, wherein the weight percentage of each component in the composition is: 20% of the active ingredients of the pesticide, 30% of the water surface expanding agent, 5% of the disintegrating agent, 20% of the adsorbent, 5% of the wetting agent, and 5% of the binder %, polymer dispersant 5%, carrier core material 10%.

Embodiment 3

[0022] Example 3: A water-dispersible granule of pesticides floating on the water surface in paddy fields, including active ingredients of pesticides and water surface expanders, disintegrants, polymer dispersants, binders, wetting agents, adsorbents, and carriers with a specific gravity lower than water The core material, wherein the weight percentage of each component in the composition is: 15% of the active ingredients of the pesticide, 30% of the water surface expanding agent, 5% of the disintegrant, 25% of the adsorbent, 5% of the wetting agent, and 5% of the binder %, polymer dispersant 5%, carrier core material 10%.

Abstract

The invention discloses a pesticide water-surface floating water dispersible granule for paddy field, which comprises the following components in percentage by weight: 10-20% of pesticide active ingredients, 15-40% of a water surface spreading agent, 5-10% of a disintegrating agent, 10-30% of an adsorbent, 5-15% of a wetting agent, 5-15% of a binder, 5-15% of a polymeric dispersant and 10-30% of a carrier core material. When the water dispersible granules floating on the water surface of the pesticide are used, pesticide application personnel only need to directly throw the water-soluble bags filled with the pesticide granules to the water surface along ridges without going to the field, the water-soluble bags are dissolved for 2-3 minutes after being thrown, and the pesticide granules are dissociated immediately, disintegrated radially and rapidly, float and expand in various directions randomly and disintegrated continuously from large to small, so that the water dispersible granules float on the water surface of the pesticide. The active ingredients are quickly and uniformly dispersed on the whole water surface to form a layer of medicine film on the water surface, and then the whole water layer is changed into suspension liquid of the medicine, so that the medicine effect is fully exerted.

Description

Technical field: [0001] The invention relates to a pesticide, in particular to a paddy field pesticide water surface floating water-dispersible granule. Background technique: [0002] Water-floating water-dispersible granules are a new type of pesticide formulation that can quickly disintegrate and disperse in water and float on the water surface after being put into water. It is a comprehensive development of water-dispersible granules and water-surface floating agents. It is mainly used in paddy fields to prevent and control paddy field pests, weeding and sterilization. The components are mainly composed of active ingredients of pesticides, floating carrier fillers, binders, and disintegrating and dispersing agents. This dosage form has been industrialized and put on the market in Japan, but there is no research on floating water-dispersible granules in China, but the research on similar dosage forms—large granules and effervescent tablets appeared earlier in China.
