Problems solved by technology

[0005] However, crops not only face pests during the whole growth process, but also the infection of some pathogens will affect the growth of crops, especially in the seed germination stage, and chlorantraniliprole is only a kind of insecticide, which cannot prevent and control harmful bacteria , unable to fully protect crops from infestation

Embodiment 1

[0028] Embodiment 1: Control effect test of diseases and insect pests

[0029] The test was carried out in the farmland of a farmer in Anyang, Henan Province. The suspension seed coating agent is a compound seed coating agent with azoxystrobin and chlorantraniliprole as the active ingredients. The single doses are respectively azoxystrobin suspension seed coating agent and chlorantraniliprole Amide suspension seed coating agent, the test seeds and test environment of each suspension seed coating agent are the same, the test treatment and application rate are shown in Table 1, and the control effect is shown in Table 2.

[0030] Among them, the disease index and the calculation formula of prevention effect are as follows:

[0031] Leaf disease index = ∑ (number of diseased leaves at all levels × relative level value) / (total number of leaves under investigation × 9) × 100;

[0032] Prevention and treatment effect (%)=(blank control group disease index-test group disease index...

Embodiment 2

[0040] Embodiment 2: 5% azoxystrobin Chlorantraniliprole suspension seed coating (both mass fractions)

[0041]

[0042]

[0043] Sodium alkyl sulfonate and alkylphenol polyoxyethylene ether are completely dissolved in distilled water, then the active ingredients of azoxystrobin, chlorantraniliprole, and other additives that have been crushed by airflow are added in sequence, and then put into a sand mill to grind twice , until the particle size of the suspension reaches D 50 2-3μm, D 90 <8μm to get the product.

[0044] The suspension seed coating prepared in this embodiment is compared with the single dose made from a single active ingredient, and the amount of each active ingredient is calculated as a standard. The amount of each active ingredient in the suspension seed coating of the present invention is less than that of each single active ingredient. On the premise of the dosage of components, the control effect of the suspension seed coating agent in the present...

Embodiment 3

[0045] Embodiment 3: 20% azoxystrobin Chlorantraniliprole suspension seed coating (both mass fractions)

[0046]

[0047] Put azoxystrobin and chlorantraniliprole through airflow crushing, wetting and dispersing agent, film forming agent, colorant, thickener, antifreeze, preservative, defoamer and water are completely dissolved, and put into sand mill in proportion Grind twice until the particle size of the suspension reaches D 50 2-3μm, D 90 <8μm, the product is obtained.

[0048] The suspension seed coating prepared in this embodiment is compared with the single dose made from a single active ingredient, and the amount of each active ingredient is calculated as a standard. The amount of each active ingredient in the suspension seed coating of the present invention is less than that of each single active ingredient. On the premise of the dosage of components, the control effect of the suspension seed coating agent in the present invention is higher than that of a single ...

Abstract

The invention relates to the field of a pesticide preparation and discloses an insect-killing and disease-resistant composite and a suspension seed coating agent thereof. The insect-killing and disease-resistant composite is composed of azoxystrobin and chlorantraniliprole with the mass ratio being 1: (4-10). The suspension seed coating agent comprises 0.5-10.0% of azoxystrobin, 1.0-30.0% of chlorantraniliprole, 1.0-8.0% of wet dispersant, 0.5-10.0% of film-forming agent, 1.0-10.0% of coloring agent, 0.1-2.0% of tackifier, 0.1-1.0% of preservative, 0.1-1.0% of de-foaming agent and the balance being distilled water. The suspension seed coating agent complexes azoxystrobin and chlorantraniliprole and advantages of azoxystrobin and chlorantraniliprole are complementary; insect killing and disease prevention can be realized by using the suspension seed coating agent for one time; and meanwhile, the pesticide effect is improved, the use amount, use types and use times of pesticides are reduced, and the suspension seed coating agent can be widely applied to agricultural fields.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to an insecticidal and disease-resistant composition and a suspended seed coating agent thereof. Background technique [0002] In modern agricultural production, the use of seed coating agents to treat seeds is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. A seed coating is a pesticide formulation used for the treatment of crop or other plant seeds with film-forming properties that solidify on the surface of the seed to form a film called a seed coat. The seed coating agent absorbs water and swells in the soil without being dissolved, allowing the water and air required for normal germination of the seeds to pass through, and the contained pesticides and seed fertilizers are slowly released, which can kill underground pests and seedling pests, and has the function of preventing and control...
