Evaluation of selected fungicides for control of powdery mildew in cantaloupe in Georgia, 2009.

摘要

The trial was conducted at the University of Georgia, Tifton Vegetable Park, in Tifton, Georgia. Cantaloupes were transplanted into fumigated black-plastic-mulched beds with 32-in. bed tops on 13 May. Beds were on 6-ft centers with a 2-ft plant spacing within rows. Plots were 25-ft long with 12 plants per plot and 10-ft unplanted borders between plot ends. The test design was randomized complete block with four replications. The crop was grown according to University of Georgia Extension guidelines except for fungicide applications. Fungicide treatments were applied using a Lee Spider Spray Trac~R with TX-18 hollow cone nozzles calibrated to deliver 40 gal/A at 75-80 psi. Rainfall during June and July was dry with the cumulative rainfall being 1.3 in. below the 91 year average.
