Insecticide composition containing clothianidin and diazinon

Abstract

The invention discloses an insecticide composition containing clothianidin and diazinon. The insecticide composition takes clothianidin and diazinon as effective components and the weight part ratio of clothianidin to diazinon ranges from 1:40 to 40:1; in actual application, the insecticide composition can be prepared into application preparations of a suspended seed coating, a suspending agent, emulsion in water, micro-emulsion, water dispersible granules, wettable powder and granules; and the total sum of clothianidin and diazinon accounts for 0.1-%-85% of the weight percent of the composition. The insecticide composition has the synergistic effect and has relatively good prevention and treatment effects on homoptera pests and lepidoptera pests on crops and soil insects; and particularly, the effects of preventing and treating aphids, leafhoppers, rice planthoppers, chilo suppressalis, tryporyza incertulas, mole crickets, grubs and the like are remarkably better than the effect of singly using a single dosage. Meanwhile, the utilization amount of pesticides is reduced, the residual amount of the pesticides on the crops is reduced, the pollution to the environment is alleviated and the production of drug resistance of the pests is delayed.

Description

technical field

[0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition with clothianidin and diazinon as active ingredients, which is applied to the control of pests on crops. Background technique

[0002] Clothianidin belongs to the second generation of neonicotinoid insecticides, and its mechanism of action acts on the nicotinic acetylcholine receptors of insect post-nerve synapses, and has contact killing, stomach poisoning and systemic activities. It is suitable for foliar spray and soil treatment, and can be used to control pests such as aphids, thrips, planthoppers, stem borers, cutworms, flea beetles, grubs, and leafhoppers.

[0003] Diazinon is an organophosphorus insecticide, and its mechanism of action is to inhibit acetylcholinesterase. It has good control effects on various pests such as Lepidoptera and Homoptera, and it can also be used for seed dressing to prevent underground ...

Examples

Embodiment 1

[0019] Example 1: 20% clothianidin·diazinon suspension concentrate.

[0020] Clothianidin 5%, Diazinon 15%, Sodium Naphthalene Sulfonate Formaldehyde Condensate 8%, Sodium Dodecyl Sulfonate 5%, Polyethylene Glycol 3%, Xanthan Gum 1%, Silicone Oil 0.1%, to Ionized water makes up 100%. The above-mentioned active ingredients, dispersant, wetting agent, antifreeze agent, thickener and defoamer are dispersed by high-speed shearing and sanded in a sand mill to form a highly dispersed and stable suspension system in an aqueous medium. A 20% clothianidin·diazinon suspension concentrate was prepared.

Embodiment 2

[0021] Example 2: 30% clothianidin·diazinon aqueous emulsion.

[0022] Clothianidin 10%, Diazinon 20%, Xylene 10%, Cyclohexanone 5%, Nonylphenol Polyoxyethylene Ether 15%, Sodium Lignosulfonate 2%, Xylitol 1%, Glycerol 1%, deionized water makes up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase, dissolve the antifreeze in water to form a water phase, slowly add the oil phase to the water phase under the action of a shearing machine, and continue to shear for about After 30 minutes, a 30% clothianidin·diazinon aqueous emulsion was prepared.

Embodiment 3

[0023] Example 3: 40% clothianidin·diazinon microemulsion.

[0024] Clothianidin 10%, Diazinon 30%, Cyclohexanone 20%, Nonylphenol Polyoxyethylene Ether 10%, Tributyl Phosphate 2%, Silicone 1%, Doppler 2%, Deionized water to make up 100% %. Dissolve the active ingredients completely in a solvent, then add emulsifier, stabilizer, penetrant, and synergist to mix evenly, and finally add deionized water, and stir thoroughly to obtain 40% clothianidin·diazinon Microemulsion.
