Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of pest resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Embodiment 1

[0071] Example 1: (60% thiamethoxam·clothianidin wettable powder)

[0072] Components and content: thiamethoxam, 15%; clothianidin, 45%; dispersant, methyl naphthalene sulfonic acid formaldehyde condensate sulfate (NNO), 3%; wetting agent, pull open powder, 2%; Carrier selects kaolin, balance.

Embodiment 2

[0073] Example 2: (30% thiamethoxam clothianidin wettable powder)

[0074] Components and content: thiamethoxam, 20%; Clothianidin, 10%; dispersant, methyl naphthalene sulfonic acid formaldehyde condensate sulfate (NNO), 2%; wetting agent, pull open powder, 4%; The carrier is selected from attapulgite and the balance.

[0075] The preparation method of Example 1-2 is as follows: according to the components and weight percentages provided in the examples, uniformly mix clothianidin, thiamethoxam, dispersant, wetting agent and carrier, and then mix them after pulverizing with a jet mill A wettable powder is prepared. The main equipment is a mixer and a jet mill.

Embodiment 3

[0076] Embodiment 3: (60% thiamethoxam·clothianidin water dispersible granule)

[0077] Components and content: Thiamethoxam, 30%; Clothianidin, 30%; Polycarboxylate, 7% as dispersant; Sodium lauryl sulfate, 3% as wetting agent; Corn starch as disintegrant , 15%; the carrier uses attapulgite and the balance.

[0078] The preparation method of the above-mentioned example 3 is: according to the components and weight percentages provided in the examples, clothianidin, thiamethoxam, wetting agent, dispersant, disintegrating agent and carrier are mixed evenly, and pulverized by a jet mill Finally, water-dispersible granules are obtained by adding water, mixing, extruding, granulating, and drying. The main equipments are mixer, jet mill and granulator.

Abstract

The invention belongs to the technical field of agricultural insecticide and particularly relates to a thiamethoxam and clothianidin compounded insecticidal composition. Thiamethoxam and clothianidin serve as effective ingredients of the insecticidal composition and are in the weight ratio of 1: (0.5 to 4), preferably 1: (1 to 3). The insecticidal composition consists of the effective ingredients of different action mechanisms, so that the action sites are increased, the overcome and delay to the generation of insect pest pesticide resistance are favored, and the insecticidal spectrum is broadened; and the pesticide effect is greatly improved, the control effect time is long, the field dosage of the effective ingredients is reduced, the production and use costs are reduced, and the insecticide residue and environmental pollution are reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural insecticides, in particular to a compound insecticidal composition of thiamethoxam and clothianidin. Background technique [0002] Clothianidin is a neonicotinoid insecticide. It is a new type of insecticide with high efficiency, safety and high selectivity. Its action is similar to that of nicotinic acetylcholine receptors, and it has contact killing, stomach poisoning and systemic activity. It is mainly used as an insecticide for preventing and controlling aphids, leafhoppers, thrips, planthoppers and other pests of Hemiptera, Coleoptera, Diptera and some Lepidoptera on rice, vegetables, fruit trees and other crops. It has the advantages of broad spectrum, less dosage, low toxicity, long duration of drug effect, no harm to crops, safe use, no cross-resistance with conventional pesticides, etc. It has excellent systemic and osmotic effects, and is an alternative to highly toxic organic pesti...
