Embodiment 1

[0018] Embodiment one: Indoor toxicity embodiment

[0019] The test refers to the "Guidelines for Indoor Bioassays of Pesticides", and the indoor toxicity test is used to illustrate whether the combination of dipropacyclopyrid and cyclopyrid has a synergistic effect on aphids and whitefly.

[0020] (1) Combined toxicity test to aphids

[0021] Indoor virulence assay was carried out by soaking insects. Dipropacyclopyrene and cyclopyrid primary drugs were configured into 5 serial concentrations of liquid medicines for future use.

[0022] Select the nymphs of green peach aphid (Myzuspersicae) cultivated in the room and of the same age. After immersing the target insects in the liquid medicine for 10 seconds, absorb the excess liquid medicine with filter paper, transfer the test insects to rearing under normal conditions, and repeat each treatment 4 times. 10 insects, treated with clean water as a control. After 24 hours, check the number of dead and alive insects, and the tes...

Embodiment 2

[0044] Embodiment two: preparation formula embodiment

[0045] (1) 15% Dipropterpirate · Cyclopyrid Water Dispersible Granules

[0046]3% dipropetal, 12% cyclopyrid, 3% GY-D06, 4% sodium lignosulfonate, 3% pull open powder BX (sodium dibutylnaphthalene sulfonate), 4% K-12 (Sodium Lauryl Sulfate), Light Calcium is added to 100% parts by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, that is, the steps of mixing ultrafine airflow pulverization, mixing, and granulating to prepare 15% dipropacyclopyrene-epoxyclomid water-dispersible granules.

[0047] (2) 35% dipropteraprene · cyclopyrid wettable powder

[0048] Weigh 10% dipropetal, 25% cyclopyrid, 5% calcium alkylphenol polyoxyethylene ether sulfonate, 8% alkylinhibition sulfonate formaldehyde condensate, 3% alkyl tea sulfonic acid Sodium and talcum powder are added up to 100% by weight. The above-mentioned raw materials are mixed, pulverized b...

Embodiment 3

[0057] Embodiment three: field use effect embodiment

[0058] Field efficacy tests of dipropyrene and cyclopyrid against bemisia tabaci and cabbage aphids.

[0059] Spraying is applied during the peak period of target pest damage. 20% dipropacyclopyrene suspension concentrate and 10% cyclopyrid water-dispersible granule were used as control agents. There were 9 drug treatments and 1 blank control area in the test, and each treatment was repeated 3 times. Before spraying, the insect population base was investigated at five points on the diagonal of each treatment area, and 10 crops were investigated at each point. 3 days, 7 days, and 14 days after spraying, investigate the control effect, record the number of live insects, and calculate the control effect.

Abstract

The invention discloses an insecticidal composition containing afidopyropen and cycloxaprid. Effective components of the composition comprise the afidopyropen and the cycloxaprid, the weight ratio ofthe afidopyropen to the cycloxaprid in the composition is 1:80 to 70:1, and the total weight of the afidopyropen and the cycloxaprid is 1%-80% of that of the composition. The insecticidal compositionprovided by the invention can be made into one of emulsifiable concentrate, water dispersible granules, wettable powder, a suspending agent, a microemulsion, an aqueous emulsion and a dispersible oilsuspension agent. The insecticidal composition provided by the invention is reasonable in components, and is applicable to the prevention of pests with piercing-sucking mouthparts and rasping-suckingmouthparts, especially aleyrodidae, aphides and thrips.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and in particular relates to an insecticidal composition containing dipropacyclopyrid and cyclopyrid, which is used for preventing and controlling pests with piercing-sucking mouthparts and file-sucking mouthparts. Background technique [0002] Aphids, Bemisia tabaci and thrips are all pests that feed on plant sap, and they are a group that is more harmful in crop production. They are small, and the symptoms of damage are often not obvious in the early stage of occurrence, and they are easy to be ignored. They live in groups on twigs, leaves, buds, flower buds, and fruits, absorbing plant juices and plundering nutrients, causing branches, leaves and flowers to curl, and even whole plants to wither or die, resulting in heavy losses of crops in our country every year. Therefore, insecticides are commonly used in most farmlands to control piercing-sucking pests. However, high-intensit...
