Embodiment 1

[0025] Embodiment 1 (indoor biological activity assay)

[0026] The insecticidal activity evaluation test was carried out according to the following methods:

[0027] Weigh a certain amount of preparation, add distilled water to dilute and prepare the medicinal solution with the required concentration. The screening concentration is from 500, 100, 20, 4, 0.8, 0.16, 0.032 mg / L, and the volume of drug treatment solution is 10 mL. The test targets are Oriental armyworm (Mythima separata), diamondback moth (Plutella xylostella), litura litura (Prodenia litura), beet armyworm (Spodoptera frugiperda), cotton bollworm (Helicoverpa armigera) and the like.

[0028] (1) Determination of oriental armyworm - soaking seedling feeding method

[0029] The corn leaves were fully soaked in the liquid medicine, dried naturally in the shade, put into a petri dish, received 3rd instar mid-stage larvae, covered and marked and placed in an observation room. The experiment was repeated 4 times. ...

Embodiment 2

[0048] Embodiment 2 (0.1% ZJ4042 emulsifiable concentrate)

[0049] 0.1% ZJ4042 EC formulation: ZJ4042 0.1%, calcium dodecylbenzenesulfonate 4%, castor oil polyoxyethylene ether 8%, N-methylpyrrolidone 8%, turpentine-based vegetable oil to make up to 100%. According to the formula requirements, add the solvent, the original drug and the emulsifier respectively, mix evenly, and if necessary, heat and dissolve in a water bath to obtain a transparent emulsifiable oil.

[0050] The embodiment is applied to the field efficacy test of preventing and controlling cabbage caterpillar. The experimental site is located in Cangqian Town, a suburb of Hangzhou City, Zhejiang Province. The crop is cabbage, and the variety is excellent. The test period was from June 6th to June 21st, 2011. The pesticide was applied on June 6th, and the pesticide was applied once in total. When the pesticide was applied, it was the early stage of the cabbage core, and the caterpillars were larvae, mainly youn...

Embodiment 3

[0054] Embodiment 3 (90% ZJ4042 wettable powder)

[0055] 90% ZJ4042 wettable powder formula: ZJ4042 90%, sodium lauryl sulfate 0.5%, naphthalene sulfonic acid formaldehyde condensate 1.5%, sodium lignosulfonate 1.5%, white carbon black 2.5%, light calcium carbonate supplemented to 100%. According to the formula requirements, the original drug, various additives and fillers are fully mixed, and after being pulverized by a jet mill, the processed product is obtained.

[0056] The embodiment is applied to the field efficacy test of controlling Plutella xylostella. The test site is located in Dacao Village, Meixu, Jiangdong District, Ningbo City, Zhejiang Province. The crop is cabbage and the variety is excellent. The test period was from May 8th to May 23rd, 2011. The pesticide was applied on May 8th, and the pesticide was applied once in total. When the pesticide was applied, it was the early stage of the cabbage core, and the Plutella xylostella larvae were larvae, mainly yo...

Abstract

The invention discloses an insecticide for agricultural pests. The insecticide contains 3-chloro-N<1>-(2-methyl-4-heptafluoroisopropyl phenyl)-N<2>-(1-methyl-1-cyanoethyl)phthalic diamide shown as a structural formula (I). The insecticide has ultrahigh insecticidal activity, high safety, reasonable toxicity, ecological toxicity and environmental compatibility, and belongs to a low-toxicity and environment-friendly pesticide.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to an insecticide containing phthalamides. Background technique [0002] The ecological and economic demands placed on insecticides are constantly increasing, especially with regard to application rate, composition of residues, selectivity, toxicity and production methods. Since insecticides are used for a period of time, pests will develop resistance to them, therefore, it is necessary to develop novel compounds with insecticidal activity. [0003] It is known that a variety of phthalamide compounds (ryanodine receptor inhibitors) have insecticidal activity (see EP0919542A2, WO2004 / 018410A1, WO2010 / 012442A2), among which the phthalamide jointly developed by Nippon Pesticide Company and Bayer Company Flubendiamide, a dicarboxamide compound, has good insecticidal activity against various agricultural and horticultural Lepidoptera pests (J. Pesticide Sci., 2005, 30(4): 354-360). At ...
