15. A method of controlling undesirable vegetation in an aquatic environment comprising
(A) spraying foliage with the composition of claim 1 or dilution thereof or
(B) pouring or adding the composition of claim 1 to the aquatic environment.
16. The method of claim 15 , wherein the aquatic environment is a flooded rice paddy or field.
17. The method of claim 15 , wherein (A) or (B) is performed before emergence of the undesirable vegetation.
18. The method of claim 15 , wherein (A) or (B) is performed after the emergence of the undesirable vegetation.
