Embodiment 1

[0020] Example 1: 33% chlorfenapyr · cyromazine suspension concentrate

[0021]

[0022] First mix other additives, shear and mix evenly in a shearing machine, then add chlorfenapyr and cyromazine, and grind in a ball mill for 2-3 hours, so that the particle diameter is less than 5mm, and then 33 % Chlorapyril·cyromazine suspension concentrate.

Embodiment 2

[0023] Example 2: 15% chlorfenapyr · cyromazine emulsion in water

[0024]

[0025]

[0026] First mix chlorfenapyr, cyromazine, trimethylbenzene, and sorbitan fatty acid ester to dissolve into a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reaction kettle, slowly add water until the phase inversion point is reached, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain 15% chlorfenapyr · Cyromazine aqueous emulsion.

Embodiment 3

[0027] Example 3: 12% chlorfenapyr·cyromazine microemulsion

[0028]

[0029] First dissolve chlorfenapyr and cyromazine completely with fatty acid methyl ester, then add other additives, mix evenly, and finally add water, after fully stirring, a 12% chlorfenapyr·cyromazine microemulsion can be prepared.

Abstract

The invention discloses insecticide composition containing chlorfenapyr and cyromazine. Effective ingredients of the insecticide composition include chlorfenapyr and cyromazine in the weight ratio being (1:10)-(10:1), and the sum of the weight of chlorfenapyr and the weight of cyromazine is 5%-98% of the weight of the composition. The insecticide composition can be prepared in one of forms of a suspending agent, a microcapsule suspending agent, an emulsion in water, a microemulsion, an ultra-low-volume liquid, wettable powder and water dispersible granules and is applied to control on Chinese chive maggots of Chinese chives, liriomyza sativae of brassicaceous vegetables and other pests. Through compounding of the two effective ingredients including chlorfenapyr and cyromazine, the use quantity of pesticides is reduced, and the use cost and pollution to the environment are reduced.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition containing chlorfenapyr and cyromazine, which is used for preventing and controlling pests such as chive leek maggot and cruciferous vegetable leafminer. Background technique [0002] Chlorfenapyr, English name: chlorfenapyr, has stomach toxicity and contact action, strong permeability on the leaf surface, and certain systemic action. Chlorfenapyr acts on the mitochondria of cells in insects, acts through multifunctional oxidases in insects, and mainly inhibits the conversion of ADP to ATP. [0003] Cyromazine, English name: cyromazine, has a strong systemic conduction effect, which induces morphological distortions in Diptera larvae and pupae, and adult eclosion is incomplete or inhibited. [0004] Chive maggots are common pests in leek cultivation. Growers must sprinkle phoxim or chlorpyrifos and other granules for p...
