Problems solved by technology

At the end of the 1980s, my country began to introduce abamectin strains. Abamectin B1, the homologue of abamectin B2, has been commercialized, but it has been used for a long time and has high resistance. B2 is more virulent to some arthropods and non-digestive nematodes than B1, especially to cucumber root-knot nematodes and Tenebrio molitor, its toxicity is 4-5 times that of B1
[0004] In addition, in the process of pesticide application, common medicinal liquids such as emulsifiable oil, water emulsion, microcapsule suspension, and granule will not be evenly dispersed around the plant root system, but will Form a lot of runoff directly through the root system, resulting in the loss and waste of liquid medicine

Embodiment 1

[0057] This embodiment is the preparation method of the microcapsule suspension formulation of the abamectin B2 fluthiazol sulfone composition with a mass component of 20%

[0058] 1) Weigh 5% abamectin B2 and 15% fluthiazol sulfone and dissolve them in 200# solvent oil, add 3% trimeric isophorone diisocyanate, stir and mix evenly to form an oil phase;

[0059] 2) Add 1% triethylenetetramine, 0.5% sodium lauryl sulfate and 0.1% xanthan gum into an appropriate amount of water and stir evenly to form a water phase;

[0060] 3) Add the oil phase to the water phase, disperse evenly under the shear of 3000r / min in a high-shear emulsifier to form a uniform emulsion, add 10% alkyl glycoside, 3% polycarboxylate salt dispersant and 4% ethylene glycol, stirred for 15 minutes, adjusted to pH 6, and added an appropriate amount of deionized water to obtain 20% avermectin B2 fluthiazol microcapsule suspension.

[0061] The same process flow can be used to obtain the microcapsule suspension...

Embodiment 2

[0064] This embodiment is the preparation method of the water emulsion type of the abamectin B2 fluthiazol sulfone composition with a mass component of 20%

[0065] 1) Weigh 10% Abamectin B2, 10% Fluthiazol, 15% Cyclohexanone, 6% Nongru 601P, 2% BBM-3, 10% alkyl glycoside and stir the solvent to form an oil phase;

[0066] 2) Weigh 4% ethylene glycol, 0.1% gum arabic, 0.5% benzoic acid, and the balance is deionized water and stir evenly to form a water phase;

[0067] 3) Under the action of a shearing machine, slowly add the water phase into the oil phase to form a uniform emulsion in water, and continue shearing for 1 hour to obtain an emulsion in water with 20% avermectin B2·fluthiazol as the active ingredient.

[0068] The same process flow can be used to obtain the water emulsion of abamectin B2 and fluthiazol single agent in various proportions, and the two single agents do not contain soil penetrating agent.

[0069] Use the above-mentioned 20% abamectin B2·fluthiazol s...

Embodiment 3

[0071] This embodiment is the preparation method of the granule dosage form of the abamectin B2 fluthiazol sulfone composition with a mass component of 10%

[0072] 1) Mix and stir 2% abamectin B2, 8% fluthiazol, 5% 600# emulsifier, 10% N-methylpyrrolidone, 10% alkyl glycoside and 1% benzoic acid;

[0073] 2) under stirring, the above-mentioned liquid mixture is added in the acid-treated porous attapulgite carrier and stirred uniformly, and then 2% film-forming agent PVA is added, and 10% Abamectin B2 is obtained after fluidized bed drying. Fluthiazol sulfone granules.

[0074] Abamectin B2 and fluthiazol single-dose granules of various proportions can be obtained with the same process flow, and the single-dose of the two does not contain soil penetrating agent.

[0075] Use the above-mentioned 10% abamectin B2 fluthiazide sulfone granules to control cucumber root-knot nematodes, the dosage is 230 g / ha, the dosage of 2% abamectin B2 granules is 210 g / ha, and 8% fluthiazide T...

Abstract

The invention discloses a pesticide composition containing abamectin B2 and application of the pesticide composition and belongs to the technical field of pesticide composition preparation. The pesticide composition is prepared from abamectin B2, an active ingredient, a soil penetrant and the balance of a pesticide excipient, wherein a mass percent content of the abamectin B2 and the active ingredient in the pesticide composition is 0.6 to 30%. A method comprises the steps: 1) dissolving the abamectin B2 and the active ingredient into an organic solvent, adding an isophorone diisocyanate trimer and stirring to form an oil phase; 2) adding triethylene tetramine, sodium dodecyl sulfate and xanthan gum into water and stirring to form a water phase; 3) adding the oil phase into the water phase, shearing to form an emulsion and adding the soil penetrant, a polycarboxylate dispersing agent and ethylene glycol to obtain a microcapsule suspending agent of the abamectin B2 composition. Compared with abamectin B2 mono agent, the abamectin B2 pesticide composition disclosed by the invention has a higher nematode preventing and treating effect, delays drug resistance generation and further has low toxin and low residue.

Description

technical field [0001] The invention relates to a pesticide composition containing abamectin B2 and a processing technology thereof, belonging to the technical field of pesticide composition preparation. Background technique [0002] Avermectin B2 (Avermectin B2) is a macrolide antibiotic, which has contact and stomach poisoning effects on pests, and has strong penetrating power. At the end of the 1980s, my country began to introduce abamectin strains. Abamectin B1, the homologue of abamectin B2, has been commercialized, but it has been used for a long time and has high resistance. The toxicity of B2 to some arthropods and non-digestive nematodes is higher than that of B1, especially for cucumber root-knot nematodes and Tenebrio molitor, and its toxicity is 4-5 times that of B1. [0003] However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. The compounding of ingredients from different variet...
