Embodiment 1

[0029] Example 1: 11% dinotefuran Tebuconazole suspension seed coating

[0030]

[0031] According to the formula requirements, using water as the medium, add the original drug, dispersant, suspending agent and antifreeze to the ingredients and mix evenly, after being pulverized by a ball mill, grind it finely in a sand mill to make a suspension seed coating agent. After passing the inspection, it is measured and packaged to be the finished product.

[0032] Using 80g-100g of the mixture mixed with 80g-100g of water to mix 1kg of wheat seeds, the control effect of wheat blight is 88.12%-92.31% and the control effect of aphid is 90.76%-97.11% 20 days after sowing.

Embodiment 2

[0033] Embodiment 2: 21% dinotefuran Tebuconazole suspension seed coating

[0034]

[0035]

[0036]

[0037] According to the formula requirements, using water as the medium, add the original drug, dispersant, suspending agent and antifreeze to the ingredients and mix evenly, after being pulverized by a ball mill, grind it finely in a sand mill to make a suspension seed coating agent. After passing the inspection, it is measured and packaged to be the finished product.

[0038] Using 8g-10g of the mixture mixed with 80g-100g of water to mix 1kg of wheat seeds, the control effect of wheat blight is 89.81%-93.01% and the control effect of aphid is 93.86%-97.54% 20 days after sowing.

Embodiment 3

[0039] Embodiment 3: 51% dinotefuran Tebuconazole suspension seed coating

[0040]

[0041] According to the formula requirements, using water as the medium, add the original drug, dispersant, wetting agent, film-forming agent and antifreeze to the ingredients and mix evenly. After being pulverized by a ball mill, grind it in a sand mill to make a suspension After the coating agent passes the inspection, it is measured and packaged to be a finished product.

[0042] Using 4g-5g of the mixture mixed with 80g-100g of water to mix 1kg of wheat seeds, the control effect of wheat blight is 90.36%-95.66% and the control effect of aphid is 93.57%-97.40% 20 days after sowing.

Abstract

The invention relates to compound pesticide and fungicide. The pesticide and fungicide comprises dinotefuran and tebuconazole which are utilized as active components. The compound pesticide and fungicide is efficient and low in toxicity, has excellent insecticide and sterilization activities to wheat aphid, damping off and banded sclerotial blight, generation of drug resistance is delayed while dosage of the pesticide and fungicide is reduced, the duration is prolonged, the pollution to the environment is reduced, and the plant safety is not hazarded.

Description

technical field [0001] The invention belongs to the field of pesticide seed coating agents, in particular a compound insecticide and fungicide with dinotefuran and tebuconazole as active ingredients. technical background [0002] Dinotefuran is a new neonicotinoid insecticide developed by Mitsui East Asia Chemical Co., Ltd. and launched in 2002. It is the only base insecticide that does not contain chlorine atoms and aromatic rings. Known as the third-generation neonicotinoid insecticide, it has the advantages of super high efficiency, broad spectrum, less dosage, low toxicity (micro-toxic preparation), long-lasting efficacy, no harm to crops, and safe use. The agent has the characteristics of contact killing, stomach poisoning, strong systemic absorption by roots, high quick-acting effect, long-lasting effect, and wide insecticidal spectrum. High insecticidal activity. It is mainly used to control aphids, leafhoppers, planthoppers, aphids, whiteflies and their resistant ...
