Experiments were conducted from 1975 to 1977 to determine the efficacy of herbicides for control of bur gherkin (Cucumis anguria L.) in peanuts (Arachis hypogaea L.). Most bur gherkins seed planted in the field germinated in the upper 2.5 cm of soil, although some seed germinated from 7 cm. In greenhouse and field experiments, preplant-incorporated applications of vernolate (S-propyl dipropylthiocarbamate) substantially reduced the green weight of bur gherkin plants and also improved the efficacy of several cracking and postemergence herbicidal treatments. Postemergence treatment sequences were much more effective when they were begun while bur gherkins were in the cotyledonary stage of development rather than the 3- to 5-leaf stage. Preplanting application and incorporation of vernolate benefin (N-butyl-N-ethyl-,,-trifluoro-2,6-dinitro-p-toluidine), followed by a cracking application of alachlor 2-chloro-2',6'-diethyl-N-(methoxymethyl)acetanilide naptalam (N-1-naphthylphthalamic acid) dinoseb (2-sec-butyl-4,6-dinitrophenol), followed by dinoseb controlled bur gherkins. Some of the most intensive herbicide programs reduced the yield of peanuts in some experiments. Bur gherkin plants that survived the herbicide treatments produced substantial quantities of fruit and seed.
