The invention relates to a 4-phenyl para-aldoxime ether-containing oxazoline compound as shown in the general formula (I), preparation of the compound and an application of the compound in pesticides. The compound represents a novel concise, wide-spectral and high-efficiency insecticidal anti-mite bactericidal herbicide structure type. When used as a novel insecticidal anti-mite bactericidal herbicide, the 4-phenyl para-aldoxime ether-containing oxazoline compound can greatly control oriental armyworm, cotton bollworm, corn borer, plutella xylostella, beet armyworm and mosquito larvae, can greatly control Tetrangychus cinnabarinus, can greatly inhibit ten pathogenic bacteria including cucumber fusarium wilt, Cercospora arachidicola, Physalospora piricola Nose, Alternaria solani, Fusarium graminearumt, late blight of potato, sclerotinia sclerotioru, Botrytis cinerea, rice sheath blight and phytophthora capsici, and can control and eliminate weeds including rape, amaranth, barnyard grass and crab grass, wherein the meaning of R is as shown in the specification.

Two series of novel 2,4-diphenyl-1,3-oxazolines containing an oxime ether moiety were designed and synthesized via the key intermediate N-(2-chloro-1-(p-tolyl)ethyl)-2,6-difluorobenzamide. The bioassay results showed that the target compounds with an oxime ether substituent at the para position of 4-phenyl exhibited excellent acaricidal activity against Tetranychus cinnabarinus in the laboratory. Moreover, all of the target compounds had much higher activities than etoxazole, as the ovicidal and larvicidal activities of the target compounds I-a-I-l and II-a-II-n against T. cinnabarinus were all over 90% at 0.001 mg L-1, but etoxazole gave only 30% and 40% respectively at the same concentration. The activity order of compounds with regard to acaricidal activity in vivo was almost consistent with their affinity activity with sulfonylurea receptor (SUR) of Blattella germanica in vitro, hence, it was supposed that the acaricidal mechanism of action of the target compounds was that they can bind with the site of SUR and therefore inhibit chitin synthesis. Moreover, the eminent effect of the compound II-l, [2-(trifluoromethyl)benzaldehyde O-(4-(2-(2,6-difluorophenyl)-4,5-dihydrooxazol- 4-yl)benzyl) oxime], against Panonychus citri and T. cinnabarinus in the field indicated that II-l exhibited a promising application prospect as a new candicate for controlling spider mites in the field.
