Embodiment 1

[0020] Benzoate 6%, Abamectin 4%, Emamectin Benzoate 2%, Sucrose 20%, Sodium Lauryl Sulfate 6%, Sodium N-Methyl N-Oleoyl Taurate 8%, polysiloxane 5%, alkylphenol ethoxylate 0.6%, acetophenone 0.5%, kaolin 13%, fatty alcohol ethoxylate 0.4% in a 60 liter portable blender dry blending activity Components benzoate and other raw materials, followed by about 15% by weight of water; the wet mass was then transferred to a basket extruder fitted with a 1.0 mm screen; each batch was divided into two smaller batches, The extrudate was dried on a fluidized bed dryer for 13-15 minutes with an inlet temperature of 60°C and an air flow of 1 m / min. And dry in a single drying cycle, no additional stirring is required in the drying cycle; under vacuum conditions, the particles are transferred to the screening device, where the particles outside the specified range of 4-50 mesh are separated; the final particle size requirements are met The product is bulk packed in 10 kg bags.

Embodiment 2

[0022] Take benzoate 6%, abamectin 3%, emamectin benzoate 1%, sucrose 15%, sodium lauryl sulfate 5%, N-methyl N-oleoyl taurine Sodium 7%, Polysiloxane 3%, Alkylphenol Ethoxylates 0.5%, Acetophenone 0.4%, Silica 0.3% Dry blend active ingredient benzoate in 60 liter portable blender and other raw materials, then add about 15% (weight) of water; then transfer the wet material to a basket extruder equipped with a 1.0 mm sieve; each batch is divided into two small batches, and the inlet temperature is controlled at 60°C The extrudates were dried on a fluidized bed dryer for 13-15 minutes under the condition of an air flow of 1 m / min. And dry in a single drying cycle, no additional stirring is required in the drying cycle; under vacuum conditions, the particles are transferred to the screening device, where the particles outside the specified range of 4-50 mesh are separated; the final particle size requirements are met The product is bulk packed in 10 kg bags.

Embodiment 3

[0024] Take benzoate 6%, abamectin 5%, emamectin benzoate 2%, sucrose 25%, sodium lauryl sulfate 7%, N-methyl N-oleoyl taurine Sodium 8%, polysiloxane 6%, alkylphenol ethoxylate 0.8%, acetophenone 0.7%, bentonite 15%, gum arabic 0.2, penetrant OT 0.3% dry blended in a 60 liter portable blender and active ingredient benzoate and other raw materials, followed by the addition of about 15% (by weight) of water; the wet mass was then transferred to a basket extruder fitted with a 1.0 mm screen; each batch was divided into two small For batches, the extrudates were dried on a fluidized bed drier for 13-15 min at an inlet temperature of 60°C and an air flow of 1 m / min. And dry in a single drying cycle, no additional stirring is required in the drying cycle; under vacuum conditions, the particles are transferred to the screening device, where the particles outside the specified range of 4-50 mesh are separated; the final particle size requirements are met The product is bulk packed i...

Abstract

The invention discloses a pesticide with low irritation and high efficiency and a preparation method thereof. The pesticide is characterized by comprising the following components by weight percent: 3-6% of benzoate, 3-5% of abamectin, 1-2% of emamectin benzoate, 15-25% of sucrose, 5-7% of sodium lauryl sulfate, 7-8% of sodium N-methyl-N-cocoyl taurate, 3-6% of polysiloxane, 0.5-0.8% of alkylphenol polyoxyethylene ether, 0.4-0.7% of acetophenone, 12-15% of filler and 0.3-0.5% of additive. The pesticide disclosed by the invention has the advantages that by adoption of the bio-derived filler, the potential influence for the environment is reduced, the safety of a user is improved, and the irritation of the pesticide to the eyes is specifically reduced. The pesticide and the preparation method have the advantages that the production process is simple, the cost is low, the pesticide resistance is good, the use is convenient and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide with low irritation and high efficiency and a preparation method thereof. Background technique [0002] Pesticide refers to a chemically synthesized substance or a substance derived from organisms or other natural substances used to prevent, eliminate or control diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, and to regulate the growth of plants and insects purposefully. mixtures of substances and their preparations. Refers to a class of drugs used to kill insects, bacteria, and harmful animals (or weeds) to ensure and promote the growth of plants and crops in agricultural production. Specifically refers to pesticides used in agriculture to control diseases and insect pests, regulate plant growth, and kill weeds. [0003] According to the source of raw materials, it can be divided into organic pesticides,...
