Compound type seed coating agent and preparation method thereof

Abstract

The invention relates to a compound type seed coating agent and a preparation method thereof, and relates to the technical field of agriculture. The compound type seed coating agent is prepared from the following components in percentage by weight through mixing: 1 to 5 g of a film forming agent, 2 to 8 g of phoxim, 5 to 10 g of an antifreezing agent, 100 to 200 g of bentonite, 5 to 10 g of a preservative, 2 to 5 g of thiram, 10 to 15 g of pigment, 3 to 7 g of an insecticide, 5 to 10 g of tebuconazole, 10 to 20 g of a bactericide, 2 to 5 g of rhodamine, 1 to 5 g of a growth additive, 5 to 10 g of a thickening agent and 100 to 200 g of water. The compound type seed coating agent disclosed by the invention is capable of effectively preventing and controlling pest and disease damage in a seedling stage, promoting and controlling the growth of young seedlings and enabling the seedlings to be tidy and strong and have more tillers, and the seedling survival rate is obviously increased.

Description

technical field [0001] The invention relates to a compound seed coating agent and a preparation method thereof, and relates to the field of agricultural technology. Background technique [0002] The growth and development of crops in nature can never be very smooth or easy to succeed. It will encounter the invasion and damage of various diseases and insect pests, etc., resulting in abnormal growth and development of crops. In severe cases, it can cause death, especially in the seedling stage. The crops have weak resistance to diseases and insect pests, so it is particularly important to effectively prevent and control pests and diseases at the seedling stage. The traditional method is to use chemical seed dressing, seed soaking and other seed disinfection methods and soil disinfection methods to prevent and control plant diseases and insect pests at the seedling stage of crops. Although these methods have certain effects, the effect is not very satisfactory. The seed soakin...

Problems solved by technology

[0004] In the compound seed coating agents currently on the market for seed coating, the active ingredients that play an insecticidal role are mostly highly toxic pesticides such as carbofuran and phorate, which bring many safety hazards to farmers. It has a serious impact on the environment and cannot meet the needs of modern agricultural development.

At the same time, in the compound seed coating agents currently on the market for preventing and treating corn head smut, most of the active ingredients that play a bactericidal role are single fungicides, and the bactericidal effect is not ideal.
