Embodiment 1、22

[0030] Embodiment 1, 22% prothioconazole · econazole · ZJ4042 suspension concentrate

[0031] According to prothioconazole 1%, econazole 1.5%, ZJ404219.5%, phosphate dispersant (FS3000) 4%, sulfonate wetting agent (SXC) 1%, magnesium aluminum silicate 1%, xanthan 0.1% glue, 0.3% silicone defoamer, 5% ethylene glycol, and the balance is deionized water. The components are pre-crushed, then added to a sand mill for grinding, and blended after high-shear mixing. Prepare 22% prothioconazole · econazole · ZJ4042 suspension concentrate.

[0032] The prepared 22% prothioconazole · econazole · ZJ4042 suspension concentrate was applied to control the small cutworm and blight of corn seedling stage. 22% prothioconazole · econazole · ZJ4042 suspension concentrate is sprayed evenly with water at the peak stage of the hatching larvae of the cutworm eggs and the early stage of the occurrence of blight according to the active ingredient 10 g / mu. The control effects of tiger and blight were...

Embodiment 2、20

[0033] Example 2, 20% prothioconazole · econazole · ZJ4042 suspension seed coating

[0034] According to prothioconazole 1.5%, econazole 1.0%, ZJ404217.5%, film forming agent PVA1.0%, NP-101.0%, polyoxyethylene ether phosphate 3.0%, ethylene glycol 5.0%, BIT0.01 %, 0.3% silicone defoamer, 0.1% xanthan gum, 1.5% warning color alkaline rhodamine, and the rest is water. The components are pre-crushed, then added to a sand mill for grinding, and subjected to high-shear After cutting and mixing, add a film-forming agent and a warning tone to prepare a 20% prothioconazole-epiconazole-ZJ4042 suspension seed coating.

[0035] The prepared 20% prothioconazole·epiconazole·ZJ4042 suspension seed coating agent was used to prevent and control small cutworm and root rot in corn seedling stage. 20% prothioconazole · econazole · ZJ4042 suspending agent carries out corn seed seed dressing treatment according to active ingredient 5 grams / 100 kilograms of seeds, normal seedling raising, and the...

Embodiment 3、50

[0036] Example 3, 50% prothioconazole · econazole · ZJ4042 water dispersible granules

[0037] According to prothioconazole 3.0, econazole 5.0%, ZJ404242%, dispersant (NNO+wood sodium) 5%, pull-off powder BX3%, K-12 (sodium lauryl sulfate) 4%, binder carboxylate Methyl (ethyl) cellulose 5%, disintegrant (glucose) 5%, white carbon black 20%, diatomaceous earth 3%, kaolin supplemented to 100% of the formula, the components are mixed evenly and air-jet pulverized into Wettable powder, adding appropriate amount of water for granulation, drying, and granulation to obtain 50% prothioconazole·epiconazole·ZJ4042 water-dispersible granules.

[0038] The prepared 50% prothioconazole·epiconazole·ZJ4042 water dispersible granule was used to prevent and control small cutworms and blight of corn seedlings. 50% prothioconazole · econazole · ZJ4042 water dispersible granules are treated with corn seed dressing according to 5 g of active ingredients per 100 kg of seeds, normal seedling cultiv...

Abstract

The invention discloses an insecticidal sterilization composition containing three active components of prothioconazole, epoxiconazole and 3-chlorine-N1-(2-methyl-4-heptafluoroisopropylanilina)-N2-(1-methyl-1-cyano ethyl) phthalic diamide with mass ratio of 0.5-5.0: 0.5-5.0: 10.0-50.0. The insecticidal sterilization composition is suitable for preventing and treating insects and diseases at the corn seedling stage.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal and fungicidal composition that can be used in the seedling stage of corn. Background technique [0002] In corn cultivation, corn seedling raising and seedling stage are very important. In the early spring season in our country, the temperature is very unstable. When the corn seedlings encounter low temperature weather, flooding, etc., the corn seedlings often rot. After investigation, the main cause of rotten seedlings is blight, bacterial wilt and so on. In addition, root rot often occurs in the seedling stage of corn, which seriously affects the normal growth of corn. At the same time, the seedling and seedling stage of corn coincides with the egg-laying and hatching stage of overwintering cutworm adults, and the larvae begin to infect and harm. At present, my country is in the stage of rapid development of cooperative organizations such as large grain...
