摘要

Squash seed were planted on 5 Sep in black plastic mulch covered beds at the Horticulture Farm, a unit of the Coastal Plain Experiment Station in Tifton, GA. Mulched beds had a 36-in. top, were laid on 6-ft centers, and were painted withwhite paint prior to planting. Seed were planted in one row per bed and were spaced 2 ft apart within the row, resulting in 8 plants per plot. Plots were 15 ft long, were separated on each end by 5 ft of bare plastic, and were arranged in a randomized complete block design with five replications. Fertility, insects and weeds were managed according to standard University of Georgia Extension Service recommendations. Fungicide treatments were applied with Lee Spider Spray Trac calibrated to deliver 40 gal/A at 75-80 psi through TX-18 hollow cone nozzles. Rainfall for Sep and Oct combined was 3.2 in. which is 2.8 in. below the 91 yr average.
