Abstract
Seven herbicides, alone or in combinations, were tested for weed control on watermelon, Citrullus lanatus (Thunb.) Matsum. & Nakai cv. Charleston Gray, and cucumber, Cucumis sativus L. cv. Chipper, during 1967 to 1972. Preemergence applications of nitralin (4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline) controlled most weed species without seriously injuring either crop. The combination of bensulide (O,O-diisopropyl phosphorodithioate S-ester with N-(2-mercaptoethyl) benzenesulfonamide) with either chloramben, methyl ester (methyl 3-amino-2,5-dichlorobenzoate) or naptalam (N-1-naphthylphthalamic acid) controlled a broader spectrum of weeds than any of the compounds applied singly.
