Herbi-cidesafeners should be applied at the same time with herbicides to ensure herbi- cides will not injure crops while controlling weeds. The research and application of safeners is of great significance to resolving or alleviating the negative effects of herbicides on crop growth. The overview, mechanism, applied research progress and existing problems of amide herbicides and their safenars are summarized.展开更多

Their structures were confirmed by 1H NMR, 13C NMR and HRMS. All title compounds were evaluated for their herbicidal and antifungal activities. Preliminary bioassay results indicated that the title compounds showed good to moderate herbicidal activity at 1000 mg/L. Compound 6q presented the best activity against Digitaria sanguinalis （L） Scop., Amaranthus retroflexus L. and Arabidopsis thaliana with an inhibition degree of five. Compound 6d also showed an inhibition degree of five against D. sanguinalis. In addition, at 50 mg/L, most compounds exhibited good in vitro antifungal activity against Sclerotinia sclerotiorum, with compound 6c showing over 90% antifungal activity against S. sclerotiorum and Pellicularia sasakii.展开更多
