The behavior of the cucumber varieties P.R. 39, Wisconsin SMR 15, Ohio MR 17, and West Indian Gherkin, after treatment with two concentrations of D.D. (dichloropropene, dichloropropane) was studied in the Isabela area. The following major results were obtained: 1. The variety P.R. 39 produced much more fruit than any of the other varieties studied. 2. Many more fruits were produced in all plots treated with D.D. than in those not treated. 3. Visual observations in the field demonstrated that, as reported by Rico Ballester et al. (6), the P.R. 39 was more resistant to the downy mildew disease than any of the other varieties studied.
