Embodiment 1

[0037] Example 1 3% Abamectin Bifenthrin Microcapsules

[0038] Utilize the processing method of the microcapsule suspension of the present invention to prepare earlier the microcapsule suspension (1.5%+1.5%) containing abamectin bifenthrin 3%, the active ingredient avermectin 1.5%, bifenthrin 1.5%, added to 12% solvent turpentine-based vegetable oil and stirred evenly, then added stabilizer triphenyl phosphite 1.5%, emulsifier polyoxyethylene castor oil 2%, initiator glyceryl lactate 2.5%, added encapsulation monomer 12% toluene diisocyanate is stirred evenly to obtain oil phase; dispersant acrylic acid-acrylate copolymer 2.5% and antifreeze agent propylene glycol 2%, antiseptic sodium benzoate 0.3%, thickener xanthan gum 1.8% are added in water (water make up to 100%) and stir evenly to obtain the water phase; preheat the oil and water to 45°C, then pour the oil phase into the water phase and turn on high-speed emulsification, wait for a stable emulsion, keep the temperature...

Embodiment 2

[0040] Example 2 3% Abamectin Bifenthrin Microcapsules

[0041] Utilize the processing method of the microcapsule suspension of the present invention to prepare respectively the abamectin microcapsule suspension and the bifenthrin microcapsule suspension, and mix the two kinds of capsule suspension products obtained according to the active ingredient weight ratio of 1:1 , to obtain 3% (ie 1.5%+1.5%) abamectin bifenthrin microcapsule suspension. Mix 3% abamectin bifenthrin microcapsule suspension with wetting agent alkyl succinate sulfonate 2.8%, ammonium sulfate 16%, polyvinyl alcohol 4%, disintegrant polyethylene glycol 3%, dispersant tristyrylphenol polyoxyethylene ether 2%, and the rest of the filler diatomaceous earth, etc. Stir and knead evenly, granulate by extrusion, the outer diameter of the extruded particles is 1mm to 2.5mm, and finally pass boiling After drying and sieving, the microencapsulated granules of abamectin bifenthrin with a yellowish brown appearance, co...

Abstract

The invention discloses a microcapsual granule for preventing and controlling diseases and pests of peanuts. Effective components of the microcapsual granule are composed of abamectin and bifenthrin which are in weight ratio of 1:1, and the effective components account for 3% of the total weight of the microcapsual granule. Pharmacodynamic tests prove that the microcapsual granule has the positivecharacteristics such as strong complementarity, obvious synergistic effect, enlarged prevention and control spectrum, application amount reduction, prolonged pesticide application period, high crop safety, environment pollution reduction and strong environmental compatibility.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and in particular relates to a microcapsule granule with remarkable effects in the prevention and control of peanut pests. Background technique [0002] In recent years, peanut pests and diseases have shown a trend of early onset, multiple onset, and reoccurrence. From seedlings to mature aphids, spider mites, young larvae of beet armyworm and cotton bollworm, senior larvae of beet armyworm and cotton bollworm, underground pests, and leaf diseases It is increasing year by year, posing a serious threat to peanut production. If reasonable and effective control is not carried out, the affected area of ​​peanuts in our country will be further expanded. [0003] Abamectin is a widely used agricultural or veterinary fungicide, insecticide and acaricide. Abamectin is a class of sixteen-membered macrolide compounds with bactericidal, insecticidal, acaricidal and nematicidal activities, and ...
