Effects of Fungicide Control of Downy Mildew (Pseudoperonospora cubensis) on Yield and Disease Management of Ridge Gourd (Luffa acutangula)

Seven fungicides were compared for the control of downy mildew on midge gourd. All treatments had significantly lower rates of disease progress curves and disease severity levels than that of the control. The highest yields were obtained from crops treated with metalaxyl + mancozeb, fosetyl-Al, and chlorothalonil. These treatments also proved to be the most economical considering the treatment costs.
