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% clothianidin diafenthiuron wettable powder)

[0072]Components and content: clothianidin, 10%; diafenthiuron, 50%; dispersant, methyl naphthalene sulfonate formaldehyde condensate sulfate (NNO), 3%; wetting agent, dodecylbenzenesulfonate Sodium acid, 3%; the carrier is kaolin, the balance.

[0073] The preparation method of Example 1 is as follows: according to the components and their weight percentages provided in the example, uniformly mix clothianidin, diafenthiuron, dispersant, wetting agent and carrier, and then mix them after pulverizing with a jet mill wettable powder. The main equipment is a mixer and a jet mill.

Embodiment 2

[0074] Example 2: (70% clothianidin diafenthiuron water dispersible granule)

[0075] Components and content: clothianidin, 10%; diafenthiuron, 60%; polycarboxylate, 7% as dispersant; sodium lauryl sulfate, 3% as wetting agent; corn starch as disintegrant , 15%; the carrier uses attapulgite, and the balance.

[0076] The preparation method of the above example 2 is: according to the components and their weight percentages provided in the example, uniformly mix clothianidin, diafenthiuron, wetting agent, dispersant, disintegrating agent and carrier, and pulverize through 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 insecticides, and particularly relates to a Clothianidin / Diafenthiuron compound insecticidal composition. The effective ingredients are Clothianidin and Diafenthiuron in a weight ratio of 1:(4-7), preferably 1:(5-6). The Clothianidin / Diafenthiuron compound insecticidal composition is composed of the effective ingredients with different action mechanisms, so that the action sites are increased, thereby being beneficial to overcoming and postponing the generation of insecticide resistance of insects, and widening the insecticidal spectrum; and the invention greatly enhances the insecticidal effect, has the advantages of long preventive effect time and lower consumption of effective ingredients in the field, lowers the production and use cost, and reduces the insecticide residue and environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of agricultural insecticides, in particular to a compound insecticidal composition of clothianidin and diafenthiuron. 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 pest...
