Use of benzyluracils for controlling weeds in cereal crops

Abstract

This invention relates to a method for controlling the weeds Papever, Matricharia, Viola, and/or Polygonum in cereal crops comprising the step of applying to the locus where the weed control is desired a herbicidal formulation comprised of a benzyluracil having the formula ##STR1## where V is chlorine; W is chlorine or methoxy; X is hydrogen; Y is chlorine or methoxy; and R is methyl or amino. Preferred benzyluracils are those where R is methyl.

We claim: 
     
       1. A method for controlling one or more of the weeds Papaver, Matricharia, Viola and Polygonum in a cereal crop comprising the step of applying to a locus where the weed control is desired an herbicidally effective amount of a composition comprising a benzyluracil having the formula ##STR6## where V is chlorine; X is hydrogen; R is methyl or amino; W is chlorine when Y is methoxy and W is methoxy when Y is chlorine in an admixture with an agriculturally acceptable carrier. 
     
     
       2. The method of claim 1 where R is methyl. 
     
     
       3. The method of claim 1 wherein the cereal crop is one of wheat, barley, oats and rye. 
     
     
       4. The method of claim 3 wherein the cereal crop is wheat. 
     
     
       5. The method of claim 1, 2, 4, or 3 wherein the weed is Papaver. 
     
     
       6. The method of claim 1, 2, 4, or 3 wherein the weed is Viola. 
     
     
       7. The method of claim 1 wherein the benzyluracil has the formula ##STR7## 
     
     
       8. The method of claim 1 wherein the benzyluracil has the formula ##STR8##
