The title compound, C21H11ClF6N2O3 (systematic name: 1-{4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-fluorophenyl}-3-(2,6-di-fluoro-benzo-yl)urea), is a benzoyl-urea pesticide. The dihedral angles between the central fluoro-benzene ring and the terminal di-fluoro-phenyl ring and chloro-phenyl ring system are 62.15 (5) and 88.03 (5)°, respectively. In the crystal, N-H⋯O hydrogen bonds link adjacent...

the entomopathogenic fungus, beauveria bassiana (bals.) vuill., is one of the facultative insect pathogens with a significant host range and host specificity. conidial survival may be affected by either environmental factors or by bio-pesticides and chemical products used to protect crop plants. in this research, compatibility of the above mentioned fungus was studied with some traditional inse...

Spinach is a frequently consumed vegetable worldwide. Chemical pesticides are widely used to produce spinach with high yield and quality. However, the unregulated use of negatively impacts human environmental health. A simple efficient method using dispersive solid-phase extraction (d-SPE) combined field experiments was conducted study residue dissipation methoxyfenozide, chlorantraniliprole, i...

We evaluated the effects of 23 insecticides and 9 fungicides on mite Neoseiulus barkeri（Hughes）collected from melon gerbera greenhouses. The nitenpyram, acetamiprid, flufenoxuron, chlorantraniliprole, pyridalyl, acequinocyl, cyenopyrafen, cyflumetofen, pyflubumide, fungicide flutianil＋mepanipyrim had no effect survival fecundity adult females. In contrast, spinosad, spinetoram, abamectin, emame...
