Problems solved by technology

[0011] For the prevention and control of pest mites that develop resistance in agriculture, one way is to introduce new ingredients that have no cross-resistance with existing varieties. However, the development cost of new ingredients is high and the development cycle is long, and they will never catch up with the development of pest mites. speed of sex
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Embodiment 1

[0039] Example 1: 30% spirodiclofen·ivermectin wettable powder

[0040] 29g spirodiclofen, 1g ivermectin, 3g sodium lauryl sulfate, 5g alkylnaphthalene sulfonate formaldehyde condensate, 8g white carbon black, and kaolin to make up to 100g, mix the above-mentioned ingredients, and place in a stirring tank Stir evenly, pass through a jet mill, and mix evenly to become 30% spirodiclofen·ivermectin wettable powder.

[0041] In this embodiment, the weight ratio of spirodiclofen and ivermectin can be changed between 1:0.01~10 (example 50:10, 45:15, 1:1, 99:1), and the optimal weight ratio is 1 : 0.03~0.5, but both total weight components are 30%, form new embodiment.

Embodiment 2

[0042] Embodiment 2: 35% spirodiclofen·ivermectin water dispersible granules

[0043] 32g spirodiclofen, 3g ivermectin, 4g sodium dodecylbenzene sulfonate, 4g sodium lignin sulfate, 2g alkylnaphthalene sulfonate formaldehyde condensate, diatomaceous earth to 100g, mix the ingredients evenly , crushed with an ultra-fine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, it became 35% spirodiclofen·ivermectin water-dispersible granules .

[0044] In this embodiment, the weight ratio of spirodiclofen and ivermectin can be changed between 1:0.01~10 (example 50:10, 45:15, 1:1, 99:1), and the optimal weight ratio is 1 : 0.03~0.5, but both total weight components are 35%, form new embodiment.

Embodiment 3

[0045] Embodiment 3: 31.5% spirodiclofen·ivermectin suspension concentrate

[0046] 30g spirodiclofen, 2g ivermectin, 2g agricultural milk 1600 # , 4g polycarboxylate, 4g ethylene glycol, 1g polyethylene glycol, 0.4g silicone oil, and water to make up 100g, the remaining components except the active ingredients in the above formula are mixed evenly through high-speed shearing, and added The active ingredients are ball-milled in a ball mill for 2-3 hours, so that the particle diameters are all below 5 μm, and a 31.5% spirodiclofen-ivermectin suspension concentrate is prepared.

[0047] In this embodiment, the weight ratio of spirodiclofen and ivermectin can be changed between 1:0.01~10 (example 50:10, 45:15, 1:1, 99:1), and the optimal weight ratio is 1 : 0.03~0.5, but both total weight components are 31.5%, form new embodiment.

Abstract

The invention belongs to the technical field of pesticides, and in particular relates to an acaricide composition containing spirodiclofen, which comprises a first active component spirodiclofen and a second active component ivermectin, wherein the weight percentage of the spirodiclofen to the ivermectin is between 1 to 0.01 and 1 to 10. The prior auxiliary agents and exipients are added to the acaricide composition to be prepared into wettable powder, water dispersible granules, suspending agents, emulsifiable solution, and micro emulsion for controlling pest mites on fruit trees. The acaricide composition is good to the safety of crops and has obvious synergism.

Description

technical field [0001] The invention relates to a compound composition with acaricidal activity, in particular to a compound composition with synergistic effect of spirodiclofen and ivermectin, belonging to the technical field of pesticides. Background technique [0002] The English name of spirodiclofen: (spirodiclofen), the chemical name is: 3-(2,4 dichlorophenyl)-2-oxo-1-oxo spiro[4.5]dec-3-en-4-yl-2 , 2-dimethylbutyrate, the molecular formula is: C 21 h 24 C 12 o 4 . The structural formula is: [0003] [0004] Spirodiclofen is a miticide with a new mechanism of action developed by Bayer Crop Science Company for more than ten years. The mechanism of action is to inhibit the synthesis of fat in the body of harmful mites, destroy the energy metabolism activities of the mites, and finally kill the harmful mites. Its acaricide mechanism is completely different from the existing acaricides, so there is no cross-resistance problem with other existing acaricides, and i...
