Embodiment 1

[0020] The production method of the water-dispersible granules containing acetamiprid and flonicamid in this embodiment is as follows: adding flonicamid and acetamiprid to the carrier, and adding a surfactant to it, mixing, and passing through a jet mill After pulverization, add water with a weight ratio of 15%, knead with a kneader, granulate with an extrusion granulator, dry in an oven, and sieve with a sieving machine to obtain a water-dispersible granule product.

[0021] The water-dispersible granules containing acetamiprid and flonicamid of the present embodiment consist of the following components by weight percentage:

[0022] Acetamiprid 10%

[0023] Flunicamid 10%

[0024] Surfactant 6.5%

[0025] Carrier balance

[0026] In this example, the weight ratio of the active ingredients acetamiprid to flonicamid is 1:1. Dispersants and wetting agents are used as surfactants. The dispersant is sodium polyacrylate with a content of 2%; the wetting agent is sodium lauryl...

Embodiment 2

[0028] The difference between this embodiment and Example 1 is that the water-dispersible granules containing acetamiprid and flonicamid in this embodiment are composed of the following components in weight percentage:

[0029] Acetamiprid 10%

[0030] Flunicamid 20%

[0031] Surfactant 6%

[0032] Carrier balance

[0033] In this example, the weight ratio of the active ingredients acetamiprid to flonicamid is 1:2. Dispersants and wetting agents are used as surfactants. The dispersant is methyl naphthalene sulfonate formaldehyde condensate sulfate (NNO), with a weight content of 4%; the wetting agent is alkylphenol polyoxyethylene ether sodium sulfate, with a weight content of 2%. The carrier is white carbon black and ammonium sulfate, and the weight content of white carbon black is 5%.

Embodiment 3

[0035] The water-dispersible granules containing acetamiprid and flonicamid of the present embodiment consist of the following components by weight percentage:

[0036] Acetamiprid 15%

[0037] Flunicamid 25%

[0038] Surfactant 6.5%

[0039] Carrier balance

[0040] In this embodiment, the weight ratio of the active ingredients acetamiprid to flonicamid is 3:5. Dispersants and wetting agents are used as surfactants. The dispersant is sodium polyacrylate with a content of 2%; the wetting agent is sodium lauryl sulfate with a content of 4.5%; the carrier is white sugar and soluble starch, and the weight content of white sugar is 20%.

Abstract

The invention belongs to the field of agricultural pesticides, and particularly relates to a method for producing an acetamiprid-and-flonicamid-contained water dispersible granule. The water dispersible granule comprises the effective components of acetamiprid and flonicamid, wherein the weight content of acetamiprid is 1%-30%; a weight ratio of acetamiprid and flonicamid ranges from 10:1 to 1:40; and the balance includes a carrier and a surface active agent. The compound is mainly used for preventing and treating lepidoptera pests, aphid, whiteflies and the like on fruit trees, vegetables and food crops. The compound has the characteristics of synergizing, expanding insecticidal range, delaying the pest resistance to insecticides and safety to the crops and the like.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides, in particular to a production method of water-dispersible granules containing acetamiprid and flonicamid. Background technique [0002] Flonicamid (flonicamid) is a new type of low-toxicity pyridinamide insect growth regulator insecticide developed by Ishihara Sangyo Co., Ltd. (ISK) in Japan. In 2007, it obtained the temporary registration certificate of pesticide products in my country. The preparation is 10% Water-dispersible granules. In addition to its contact and stomach poisoning effects, flonicamid also has a good nerve agent and rapid antifeedant effect. Aphids and other piercing-sucking mouthparts will be quickly prevented from sucking the juice after inhaling the plant juice with flonicamid. There will be no excrement at all within 1 hour, and eventually they will die of starvation. [0003] Acetamiprid is a new generation of nicotine ultra-high-efficiency new insec...
