Abstract:
A fungicidal composition comprising from about 0.1 to 99.9 percent by weight of synergistically effective amounts of(a) at least one benzophenone of formula I â€ƒwherein R1 represents a halogen atom, an optionally substituted alkyl, alkanoyloxy or alkoxy group; or a hydroxy group, R2 represents a halogen atom or an optionally substituted alkyl group, R3 independently represents a halogen atom, an optionally substituted alkyl or alkoxy group or a nitro group; m is 0 or an integer of 1 to 3; R4 represents a halogen atom, a cyano, carboxy, hydroxy or nitro group or an optionally substituted alkyl, alkoxy, alkenyl, alkylthio, alkylsulphinyl, alkylsulphonyl or amino group; R5 represents an optionally substituted alkyl group; R6 represents a halogen atom or a nitro group, an optionally substituted alkyl, alkoxy, alkenyloxy, alkynyloxy, alkylthio, cycloalkyl, cycloalkyloxy, aryloxy group; R7 independently represents a halogen atom, an optionally substituted alkyl, alkenyl, alkynyl, alkoxy, alkenyloxy, alkynyloxy, cycloalkyl, cycloalkoxy group; and n is 0 or 1; and (b) at least one fungicidally active compound selected from a strobilurine derivative having a formula â€ƒwherein W represents N or CH; B represents a â€”Oâ€”, â€”OCH2â€”, a â€”CH2Oâ€”, a pyrimid-4,6-dioxydiyl group or a group of formula R12 represents a C1-4 alkyl group; R13 represents a C1-6 alkoxy or a C1-6 alkylamino group; R14 represents a hydrogen or halogen atom or a cyano, a C1-4 alkyl or a C1-4 haloalkyl group; and s is 0, 1 or 2; wherein the ratio by weight of an (a) to (b) compound is from about 100:1 to 1:100; together with from about 99.9 to 0.1 percent by weight of a fungicidally acceptable carrier and/or surface active agent therefor.
