Problems solved by technology

The pear psyllid does direct damage by sucking buds, leaves, and twig juice from adults and nymphs, and secretes mucus, causing miscellaneous bacteria, causing indirect damage to leaves, brown spots appearing, causing early leaf fall, and polluting fruits at the same time, seriously affecting the yield of pears and quality
[0005] The medicaments currently registered in the Ministry of Agriculture for the prevention and treatment of pear psyllids are mainly abamectin, beta-cypermethrin, imidacloprid and their mixed preparations, which have been used for many years, and the resistance develops rapidly, resulting in poor actual control effect. It is urgent to invent a A safe and pollution-free pesticide that can effectively control pear psyllids

Embodiment 1

[0030] Weigh 11% epoxycloprid, 11% spirotetramat, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.3% xanthan gum, 5% Propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29, produced by Nanjing Sixin Applied Chemicals Company), and deionized water were added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 22% epoxycloprid spirotetramat suspending agent.

Embodiment 2

[0032]Weigh 5% epoxycloprid, 15% spirotetramat, 4% TERSPERSE 4894 (produced by Huntsman, USA), 1.5% TERSPERSE 2500 (produced by Huntsman, USA), 1% TERSPERSE 2020 (produced by Huntsman, USA) Mai company), 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), deionized water plus to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 20% epoxycloprid spirotetramat suspending agent.

Embodiment 3

[0034] Weigh 5% epoxycloprid, 50% spirotetramat, 4% GY-D06, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1% sodium lauryl sulfate, 3% White carbon black, 3% sodium polyphosphate and kaolin are added to 100% by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 55% epoxycloprid spirotetramat wettable powder.

Abstract

The invention discloses a cycloxaprid and spirotetramat-containing insecticidal composition and applications thereof. Effective active ingredients include first active ingredient cycloxaprid and second active ingredient spirotetramat, and the weight rate of the first active ingredient to the second active ingredient is 1:10-10:1, preferably 1:7-7:1. The composition can be prepared into agriculturally allowable drug forms such as suspending agents, water dispersible granules or suspension emulsions. The insecticidal composition disclosed by the invention is reasonable in ingredients and good in insecticidal effect; the activity and the insecticidal effect of the insecticidal composition are not the simple superposition of the activities of the ingredient, compared with the existing single preparations, besides a significant insecticidal effect, the insecticidal composition also has a significant synergistic effect, is good in crop safety, and satisfies the requirements on the safety of pesticide preparations; the insecticidal composition disclosed by the invention has a significant prevention and control effect on pear psylla.

Description

technical field [0001] The invention relates to an insecticidal composition, which is composed of a first active ingredient epoxycloprid and a second active ingredient spirotetramat, and belongs to the technical field of compound pesticides. Background technique [0002] Epoxycloprid is a neonicotinoid insecticide, created by Wuhan Engineering University, chemical name: 1-(2,3-epoxypropyl)-N-nitroimidazolidin-2-ylamine, chemical formula C 6 h 10 N 4 o 3 . It has systemic, stomach poisoning and contact killing effects on pests. As a neonicotinoid insecticide, epoxycloprid has resistance risk during use, and rational mixing with different types of insecticides is of great importance for the full and effective promotion of epoxycloprid and prolonging its service life effect. [0003] Spirotetramat, English common name: spirotetramat, chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4 ,5]-dec-3-en-2-one. Spirotetramat is a new type of tetronic aci...
