Embodiment 1

[0039] Embodiment one: 5.1% oligochitosan emamectin emamectin saline emulsion

[0040] The active ingredient is, chitosan oligosaccharide: emamectin benzoate = 1:50 (weight percent)

[0041] The weight percentage of each component: chitosan oligosaccharide 0.1%, emamectin benzoate 5%, agricultural emulsion 600# 5%, xanthan gum 0.5%, silicone defoamer 0.1%, glycerin 3%, water to 100% . Add active ingredients, emulsifiers and other additives together to dissolve into a uniform oil phase; under high-speed stirring, add the oil phase to water and mix evenly to prepare 5.1% oligochitosan emamectin emamectin salt water emulsion.

[0042] The above-mentioned other components can be selected according to the dosage form of the insecticide composition, which is well known to those skilled in the art.

[0043] The pesticide composition of the present invention can be processed into emulsifiable concentrates, suspension concentrates, water-dispersible granules, microemulsions, soluble ...

Embodiment 2

[0051] Embodiment two: 26% chitosan oligosaccharide dichlorvos emulsifiable concentrate

[0052] The active ingredient is, chitosan oligosaccharide: dichlorvos = 1:25 (weight percentage)

[0053] The weight percentage of each component is: chitosan oligosaccharide 1%, dichlorvos 25%, agricultural emulsion 600#5%, agricultural emulsion 700#5%, and xylene supplemented to 100%. Add the active ingredient, emulsifier and solvent into the mixing kettle in sequence according to the ratio of the formula, and stir evenly to obtain 26% chitosan oligosaccharide dichlorvos EC.

Embodiment 3

[0054] Embodiment three: 13.5% chitosan oligosaccharide·beta-cypermethrin emulsifiable concentrate

[0055] The active components are, oligochitosan: beta-cypermethrin=1:12.5 (weight percentage) The weight percentage of each component is: oligochitosan 1%, beta-cypermethrin 12.5%, agricultural emulsion 600#2%, agricultural emulsion 1601#5% , cyclohexanone 15%, mineral oil to make up to 100%. Add the active ingredient, emulsifier and solvent into the mixing tank in sequence according to the ratio of the formula, and stir evenly to prepare 13.5% oligochitosan·beta-cypermethrin emulsifiable concentrate.

Abstract

The invention provides a pesticide composition containing chitosan oligosaccharide. The pesticide composition of the invention contains active components: chitosan oligosaccharide, and emamectin benzoate, dichlorvos, beta-cypermethrin, trichlorfon, abamectin, and phoxim , any one of Lesburn or a combination thereof. The pesticide composition of the present invention contains other components besides the active components. The other components are: one or more of dispersants, wetting agents, antifreeze agents, stabilizers, preservatives, thickeners, emulsifiers, defoamers, solvents and carriers. The invention also discloses a pesticide insecticide of the chitosan oligosaccharide-containing pesticide composition and its application. The chitosan oligosaccharide-containing pesticide composition of the present invention can be processed into emulsifiable concentrates, suspension concentrates, water-dispersible granules, microemulsions, soluble powders, and granules by adopting common methods in the art.

Description

technical field [0001] The invention relates to a pesticide composition containing chitosan oligosaccharide, a pesticide insecticide and an application thereof, belonging to the field of pesticides. Background technique [0002] Bactrocera dorsalis (Hendel), also known as oriental fruitfly, belongs to Diptera, Tephritidae, Bactrocera. The range of parasitism is very wide, and it can parasitize and harm more than 250 kinds of fruit and vegetable crops such as mango, citrus, grape, pear, jujube, pomegranate, banana, lychee, tomato, eggplant, cucumber, and pumpkin. Its larvae damage the fruit, live in the flesh of the fruit and feed on it, causing the fruit to rot and drop the fruit. Because of the strong fecundity, short development cycle, and overlapping generations of the insect, it is harmful all the year round. Especially in southern China, some fruits and vegetables have been almost wiped out, causing huge economic losses. It is a destructive pest. [0003] At present, ...
