Pesticides, fungicides or herbicides comprising 3-phenyl-pyrone derivatives, useful e.g. as insecticides, acaricides, nematocides or fungicides for plant protection or as veterinary ectoparasiticides

摘要

3-(2-Methyl-4-fluorophenyl)-4-hydroxy-5-methyl-6-(pyrid-2-yl)-pyrone or 3-(2-methyl-4-chlorophenyl)-4-hydroxy-5-methyl-6-(4-fluorophenyl)-pyrone is used as pesticide, fungicide or herbicide. Pesticidal, fungicidal and herbicidal compositions contain a 3-phenyl-pyrone of formula (I), together with extenders and/or surfactants. (i) X = pyrid-2-yl; and Y = F; or (ii) X = 4-fluorophenyl; and Y = Cl.
