Embodiment 1

[0016] Example 1: 33% cyclocloprid·pyridine quinazoline suspension concentrate.

[0017]

[0018] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add cyclopyrid and pyridine quinazoline, grind in a ball mill for 2-3 hours, so that the particle diameter is 5mm As follows, a 33% cyclocloprid-pyridine-quinazoline suspension concentrate can be prepared.

Embodiment 2

[0019] Example 2: 24% Cyclocloprid·Pyridine-Quinazoline Suspension Concentrate.

[0020]

[0021] The specific operation steps are as follows: firstly, cyclopyridam, pyridine quinazoline, trimethylbenzene and sorbitan fatty acid ester are mixed together, and dissolved to form a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reaction kettle, slowly add water until the phase inversion point is reached, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain 24% epoxy worm Pyridine·pyridine quinazoline water emulsion.

Embodiment 3

[0022] Embodiment 3: 20% cyclocloprid · pyridine quinazoline microemulsion.

[0023]

[0024] The specific operation steps are as follows: first dissolve cyclopyrid and pyridine quinazoline completely with fatty acid methyl ester, then add other additives, mix well, finally add water, after fully stirring, 20% epoxypyrid can be obtained Pyridine·pyridine quinazoline microemulsion.

Abstract

The invention discloses an insecticidal composition containing cycloxaprid and pyridine quinazoline. The active ingredients of the insecticidal composition are cycloxaprid and pyridine quinazoline, the weight ratio of cycloxaprid to pyridine quinazoline is 1:10-10:1, and cycloxaprid and pyridine quinazoline account for 5%-93% of the weight of the insecticidal composition. The insecticidal composition is in any one of the dosage forms of suspension, water-dispersible granules, emulsion in water, microemulsion and wettable powder, and is applied to prevention and treatment of thrips, aphids, aleyrodid and other agricultural insects.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and the field of application thereof, in particular to a binary composition with cyclopyrid and pyridine quinazoline as active ingredients, which is used to prevent and control agricultural pests such as thrips, aphids and whiteflies. Background technique [0002] The problem of resistance to agricultural diseases is a global problem, and it has always been the focus of attention of agricultural science and technology workers. With the continuation of chemical control of pests and weeds year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of pests and weeds is becoming more and more serious, and the types of resistant pests and weeds are increasing. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers,...
