Description

Technical Field

[0001] This invention belongs to the field of pesticide insecticide technology and discloses an insecticidal composition containing chlorantraniliprole and its application. Background Technology

[0002] Fluchlordiniliprole (CAS No.: 2129147-03-9) is a diamide insecticide belonging to the ryanodine receptor modulator class. It works by acting on the ryanodine receptors of insects, disrupting the calcium ion balance in the body, causing muscle paralysis, cessation of feeding, and eventual death in pests, primarily through stomach poisoning. It is highly effective in controlling most lepidopteran pests on crops such as cabbage, rice, corn, cotton, and fruit trees, including diamondback moth, beet armyworm, rice stem borer, rice leaf roller, corn borer, cotton bollworm, and fall armyworm. It also has high efficacy against thrips and other thrips, as well as some piercing-sucking pests. Its core advantages include low dosage, long-lasting effect, no cross-resistance with conventional insecticides, low toxicity to mammals, and environmental friendliness.

[0003] Benzpyrimoxan (CAS: 1449021-97-9) is a novel arylalkoxypyrimidine insecticide, belonging to the molting hormone titer interfering agent. Its novel mechanism of action is to interfere with the molting process of insects, inhibit the normal molting of nymphs, and cause their death. It has high selectivity and is specifically effective against rice planthopper nymphs such as brown planthopper and white-backed planthopper, as well as leafhoppers.

[0004] Dicloromezotiaz (CAS: 1263629-39-5) is a novel metronidazole insecticide belonging to IRAC Group 9. It acts on insect nicotinic acetylcholine receptors (nAChR) and acts as a competitive antagonist to interfere with nerve conduction, causing paralysis and death of pests. It has a very broad insecticidal spectrum and is highly effective in controlling a variety of pests, including Lepidoptera (diamond moth, cotton bollworm, fall armyworm, rice stem borer, etc.) and Hemiptera (aphids, planthoppers, whiteflies, leafhoppers, etc.). It has stomach poison and contact activity, is fast-acting and has a long-lasting effect, requires low dosage, and is safe for mammals and the environment.

[0005] Flupyrimin (CAS: 1689566-03-7) is a novel pyridinyl subunit insecticide belonging to IRAC 4F group. It is an insecticidal nicotinic acetylcholine receptor (nAChR) antagonist, which paralyzes and kills pests by blocking nerve transmission. It has contact, stomach poison, root systemic, and translaminar activity, and has a broad insecticidal spectrum. It is highly effective in controlling Hemiptera (planthoppers, aphids, whiteflies, leafhoppers), Lepidoptera (diamond moth, beet armyworm), Thysanoptera (thrips), Coleoptera (rice water weevil), and Diptera sanitary pests.

[0006] Flometoquin (CAS: 875775-74-9) is a novel quinoline insecticide and acaricide belonging to IRAC Group 34. It kills pests by inhibiting the Qᵢ site of mitochondrial complex III, blocking electron transport and energy metabolism, and has no cross-resistance. It has contact and stomach poison effects, is highly effective against thrips (Thysanoptera), and also has excellent control effects against a variety of resistant pests and virus-transmitting pests such as Hemiptera, Acari, and Lepidoptera.

[0007] Lepidoptera and Hemiptera pests are the two most damaging groups in agricultural production. Lepidoptera larvae mainly feed on leaves, bore into stems, and bore into fruits, causing notches, dead hearts, and rotten fruits, which seriously affect yield and quality. Hemiptera pests mostly have piercing-sucking mouthparts, sucking plant sap, causing yellowing of leaves and wilting of plants. They also spread various plant viral diseases, causing sooty mold. The two often occur together and are prone to developing pesticide resistance, which puts great pressure on prevention and control.

[0008] Binary compound insecticides can significantly broaden the insecticidal spectrum and improve control efficiency through the synergistic effect of agents with different mechanisms of action; they can also delay the development of insecticide resistance in pests, reduce the dosage of single agents, reduce pesticide residues, take into account both rapid and sustained effects, and improve the stability of control efficacy. They are an important technical means for integrated pest management and resistance control. Summary of the Invention

The previous crop in the experimental field was summer maize. The soil fertility of the experimental site was moderate, and the irrigation and drainage were convenient. Fertilization and management were consistent with the local standards.

[0128] Experimental target: wheat aphid.

[0129] Experimental Design: The experiment consisted of 8 treatments, each repeated 4 times, with each plot measuring 50m². 2 The cells were randomly arranged, and the fertilizer and water management and cultivation conditions were basically the same across cells.

[0130] Experimental Methods: The experiment was conducted during the early grain-filling stage of wheat (April 18, 2025), when aphid infestation reached the control threshold. The spraying equipment used was a Huifeng brand 3WBD-20 backpack electric sprayer manufactured by Taizhou Huaisheng Electromechanical Co., Ltd., with a working pressure of 0.2~0.5 MPa, a single nozzle, and a water consumption of 675 kg / hm². 2 The stems and leaves were sprayed evenly, and the pesticide was applied once. There was no rainfall within 14 days after the application.

[0131] Experimental survey: Aphid population survey was conducted once before pesticide application, and then again at 3, 7, and 14 days after pesticide application to survey the number of aphid-infested plants and live aphids, for a total of 4 surveys. Five fixed survey points were set up in each plot, with 20 plants surveyed at each point, for a total of 100 plants surveyed in each plot. The population reduction rate and control effect were calculated.

One application was made during the peak emergence period of early-stage rice planthopper nymphs, with even spraying, focusing on the lower part of the rice plants. Care was taken to prevent pesticide droplets from drifting to adjacent treatment plots. A two-stage dilution method was used to prepare the pesticide solution. After thorough mixing, the solution was sprayed evenly onto the rice plants, while maintaining a 3-5 cm water layer in the field for 7 days.

[0140] Safety investigation: Throughout the field trial, the effects of the tested pesticide on rice plants were observed periodically to determine whether there was any phytotoxicity or growth-promoting or growth-inhibiting effect.

[0141] Methods for investigating the efficacy of the pesticide: Parallel skip sampling was used, with 15 sampling points in each plot, and 2 plantlets at each point. The initial insect population was investigated before pesticide application, and the control effect was investigated 1 day, 3 days, and 7 days after application. Specifically, a white porcelain dish was placed at an angle on the lower part of the rice plantlet, and the plantlet clump was quickly tapped 1-2 times, then quickly lifted up to count the number of rice planthoppers.

[0142] Methods for calculating drug efficacy:

[0143] The results of the field efficacy trials are shown in the table below:
