Experimental Use of Silvex and Other Aquatic Herbicides in Georgia Farm Ponds

The results of two years experimental weed control in Georgia Farm Ponds using silvex,2 propylene glycol butyl ether ester, dalapon, sodium salt of 2,2dichloropropionic acid; 2, 4-D granules of iso-octyl ester of 2,4-dichlorophenoxy acetic acid. Residual control and overall effectiveness is evaluated over a twoyear period on acquatic weeds in approximately 100 ponds. Preliminary screening of Inverton, an invert emulsion of 2, 4, 5-trichlorophenoxy acetic acid; Carlon, a solution of dalapon and silvex; and simazine, 2-chloro-4, 6 bis( ethylamino) -S-trizaine are presented.
