Problems solved by technology

In addition, if seeds and seedlings are eaten by pests, or infected by pathogenic bacteria, diseased seedlings and dead seedlings will appear, which will reduce the effective number of crops per unit area, resulting in large-scale production reduction and quality decline of crops
[0009] Seed treatment agents containing a single active component are frequently used, the actual effect is poor, and the scope of action is narrow, which cannot achieve the purpose of eliminating germs
Although thiaminide and fludioxonil are highly effective as inducers and fungicides, their long-term single-dose use will easily cause the disease to develop drug resistance, resulting in problems such as increased dosage, reduced control effect, and shortened duration , is not conducive to the sustainable development of the environment

Embodiment 1

[0061] Example 1: 51% Methiamin · Fludioxonil Seed Treatment Suspension Concentrate (1:50)

[0062] Components: Methiamin 1%, Fludioxonil 50%, Alkylphenol Polyoxyethylene Phosphate 3%, Polyoxyethylene Polyoxypropylene Ether Block Copolymer 5%, Ethylene Glycol 4%, Yellow Raw gum 0.15%, silicone defoamer 0.15%, rhodamine 0.15%, kason 0.8%, water to make up to 100%.

[0063] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and then you can prepare 51% methiamine. Bactonitrile seed treatment suspension.

Embodiment 2

[0064] Example 2: 23% Methiamin · Fludioxonil seed treatment dry powder (1:45)

[0065] Components: Methiamin 0.5%, Fludioxonil 22.5%, Sodium Dodecylbenzene Sulfonate 2%, Sodium Lignosulfonate 3%, Hydroxyethyl Cellulose 0.6%, White Carbon Black 5%, Rose Refined 0.3%, talc topped up to 100%.

[0066] Preparation method: Mix all the components uniformly, firstly crush them mechanically, then airflow crush them, and mix them uniformly to prepare 23% Methiamin · Fludioxonil seed treatment dry powder.

Embodiment 3

[0067] Example 3: 42% Methiamin · Fludioxonil Seed Treatment Microcapsule Suspension (1:20)

[0068] Components: Methiamin 2%, Fludioxonil 40%, Dimethylolurea 2.5%, Gum Arabic 1%, Styrene Maleic Anhydride Copolymer Sodium Salt 1.5%, Citric Acid 0.6%, Lignosulfonic Acid Sodium 1.5%, Alkylphenol Ethoxylate Phosphate 2%, Ethylene Glycol 2.5%, Xanthan Gum 0.15%, Silicone Antifoam 0.1%, Cathone 0.5%, Rhodamine 0.2%, make up to 100% .

[0069] Preparation method: wet pulverize the original medicines of thiaminide and fludioxonil to make a suspension, add dimethylolurea and gum arabic, trigger a polyurea reaction under acidic conditions to form a coating on the active ingredients, and finally add Structural regulators such as ethylene glycol and xanthan gum can be used to obtain 42% thiaminamide·fludioxonil seed treatment microcapsule suspension.

Abstract

The invention discloses a seed treatment agent composition and application thereof, relating to the technical field of pesticide compounding. The seed treatment agent composition disclosed by the invention contains an effective component A and an effective component B in a weight ratio of (1-50) to (1-50), wherein A is methiadinil, and B is fludioxonil. The seed treatment agent composition can act on different target points so as to provide all-round protection to seeds. The seed treatment agent composition is good in environmental consistency, low in toxicity and safe to creatures such as human, livestock and natural enemies and belongs to broad-spectrum and efficient seed treatment agent compositions. The seed treatment agent composition has a relatively high synergistic interaction effect, the application cost is lowered, and the control effect is obviously superior to the control effect of single-component agent. The broad-spectrum and efficient seed treatment agent composition has obvious promotional values.

Description

technical field [0001] The invention relates to a seed treatment agent composition and its application, in particular to a seed treatment agent composition containing thiamin and fludioxonil as active ingredients and its application, and belongs to the technical field of pesticide compounding. Background technique [0002] Seed treatment agent is a kind of pesticide used for seed surface treatment. The active ingredients are mainly insecticides or fungicides. Compared with conventionally used pesticides for stem and leaf treatment, seed treatment agents have obvious advantages in reducing the amount and frequency of pesticide application, reducing environmental pollution, reducing field operations, saving labor, saving costs, and increasing efficiency. [0003] In recent years, my country has vigorously advocated and promoted the seed treatment technology, which is mainly to compound insecticides, fungicides, compound fertilizers, trace elements and plant growth regulators t...
