Fungicidal compositions

Abstract

A composition for control of phytopathogenic diseases on useful plants or on propagation material thereof, that, in addition to customary inert formulation adjuvants, comprises as active ingredient a mixture of component (A) and a synergistically effective amount of component (B), wherein component (A) is Cyprodinil; and component (B) a compound selected from compounds known for their fungicidal activity, is particularly effective in controlling or preventing fungal diseases of useful plants.

What is claimed is: 
     
         1 . A composition for control of phytopathogenic diseases on useful plants or on propagation material thereof, that comprises as active ingredient a mixture of component (A) and a synergistically effective amount of component (B), wherein component (A) is Cyprodinil; and component (B) is a compound of formula A-2 
       
         
           
           
               
               
           
         
       
     
     
         2 . A composition according to  claim 1 ; wherein a weight ratio of component (A) to component (B) is from 2000:1 to 1:1000. 
     
     
         3 . A method of controlling phytopathogenic diseases on useful plants or on propagation material thereof, which comprises applying to the useful plants, the locus thereof or propagation material thereof a composition according to  claim 1 . 
     
     
         4 . A method of controlling phytopathogenic diseases on useful plants, which comprises applying to the useful plants or the locus thereof a composition according to  claim 1 . 
     
     
         5 . A method according to  claim 4 , wherein the useful plants are cereal plants. 
     
     
         6 . A method according to  claim 4 , wherein the useful plants are fruit plants or vegetable plants. 
     
     
         7 . A method according to  claim 4 , wherein the useful plants are grape plants. 
     
     
         8 . A method of protecting natural substances of plant origin, which have been taken from the natural life cycle, which comprises applying to said natural substances of plant origin or their processed forms a composition according to  claim 1 . 
     
     
         9 . A composition according to  claim 1 , wherein Cyprodinil is present as (i) a salt of Cyprodinil or (ii) a metal complex of Cyprodinil. 
     
     
         10 . A composition according to  claim 2 , wherein the weight ratio of component (A) to component (B) is from 100:1 and 1:100. 
     
     
         11 . A composition according to  claim 10 , wherein the weight ratio of component (A) to component (B) is from 20:1 and 1:50. 
     
     
         12 . A method according to  claim 4 , wherein the useful plants are wheat plants. 
     
     
         13 . A method according to  claim 4 , wherein the step of applying comprises applying Cyprodinil at a rate of 5 to 2000 g a.i./ha and the compound of formula A-2 at a rate of 1 to 5000 g a.i./ha. 
     
     
         14 . A method according to  claim 4 , wherein the step of applying comprises applying from 20 to 4000 g of the composition per hectare.
