Fungicidal agents processes for their preparation and their use for combating fungi

Abstract

A synergistic fungicidal composition comprising (1) at least one carboxidide of the formula ##STR1## in which Y represents a bifunctional group linking the two carbonyl groups with formation of an optionally substituted 5-membered heterocyclic ring with a total of 1 or 2 hetero-atoms (O and N), and (2) ##STR2##

What we claim is: 
     
       1. A fungicidal composition comprising a fungicidally effective amount of (1) .[.at least one carboximide of the formula ##STR10## in which Y represents a bifunctional group linking the two carbonyl groups with formation of an optionally substituted 5-membered heterocyclic ring with a total of 1 or 2 hetero-atoms (O and N),.]. ##STR11## and (2), ##STR12## the weight ratio of component (1) to component (2) ranging from about 1:1 to 1:4. 
     
     
       2. A composition according to claim .[.1.]. .Iadd.10 .Iaddend.wherein component (1) comprises ##STR13## .[. 
     
     
       3.  A composition according to claim 2 wherein component (2) comprises ##STR14## and the weight ratio of component (1) to component (2) is from about 1:1 to 1:4..]. 
     
     
       4. A composition according to claim .[.3.]. .Iadd.2 .Iaddend.wherein component (1) comprises ##STR15## 
     
     
       5. A composition according to claim 1, wherein component (2) comprises ##STR16## .[. 
     
     
       6.  A composition according to claim 5, wherein component (1) comprises ##STR17## 
     
     
       7. A method of combating fungi which comprises applying to the fungi, or to a habitat thereof, a composition according to claim 1. 
     
     
       8. A method according to claim 7, in which the total active compounds are applied to soil in an amount of about 0.00001 to 0.1% by weight. 
     
     
       9. A method according to claim 7, in which the total active compounds are applied to seed in an amount of about 0.001 to 50 g per kg of seed. .Iadd. 10. A fungicidal composition comprising a fungicidally effective amount of (1) ##STR18##.Iaddend. and (2), ##STR19## the weight ratio of component (1) to component (2) ranging from about 1:1 
     
     
        to 1:4. .Iadd. 11.  A method of combating fungi which comprises applying to the fungi, or to a habitat thereof, a composition according to claim 10. .Iaddend..Iadd. 12. A method according to claim 11, in which the total active compounds are applied to soil in an amount of about 0.00001 to 0.1% by weight. .Iaddend..Iadd. 13. A method according to claim 11 in which the total active compounds are applied to seed in an amount of about 0.001 to 50 g per kg of seed. .Iaddend.
