Fungicidal agent combinations
View Patent ↗The invention relates to novel fungicidally active compound combinations of 2′-cyano-3,4-dichloroisothiazole-5-carboxanilide of the formula and active compounds listed in the disclosure.
1. A synergistic fungicidal composition comprising an active compound combination consisting of
(a) 2′-cyano-3,4-dichloroisothiazole-5-carboxanilide of formula (I)
and
(b) one or more of the compounds selected for active groups
(1) a neonicotinyl of formula (II-b)
and/or
(2) a phenylpyrazole of formula (IV)
in which
(i) for fipronil (formula IV-a), R 3 is —CF 3 ,
or
(ii) for ethiprole (formula (IV-b), R 3 is C 2 H 5 ,
and
(c) an extender or extenders and/or surfactants.
2. A composition according to claim 1 wherein in the active compound combinations the weight ratio of the active compound of formula (I) to
active compound of group (1) is between 1:0.1 and 1:100, and/or
active compound of group (2) is between 1:0.5 and 1:50.
3. A method for controlling fungi in viticulture and dicotyledonous crops comprising applying an effective amount of an active compound combination according to claim 1 to the fungi and/or their habitat.
4. A process for preparing a fungicidal composition according to claim 1 comprising mixing the active compound combination with an extender or extenders of the extenders and/or surfactants.
5. A composition according to claim 1 , wherein component (b) is fipronil.
6. A composition according to claim 1 , wherein the active compound combination consists of isotianil and thiacloprid.
7. A composition according to claim 1 , wherein the active compound combination consists of isotianil and ethiprole.
8. A composition according to claim 1 wherein in the active compound combinations the weight ratio of the active compound of formula (I) to
active compound of group (1) is between 1:0.1 and 1:50, and/or
active compound of group (2) is between 1:1 and 1:20.
