摘要

The experiment, arranged as a randomized complete block with 4 replications, was conducted in a field (Aura sandy loam) naturally and artificially-infested with Phytophthora capsici and Colletotrichum sp., respectively, at the RutgersAgricultural Research and Extension Center (RAREC), Bridgeton, New Jersey. On 9 Jun, bell pepper seedlings obtained from a local producer were transplanted by hand with a waterwheel transplanter into staggered double rows (18” apart in row) on high, raised beds. All beds were spaced 5 ft apart covered with black plastic mulch with drip irrigation. All treatment plots were 15 ft long with guard rows of Phytophthora-susceptible bell pepper cv. ‘Camelot’ planted between plots. Fertility schedule and management of insect and weeds were done according to local recommendation guidelines. Fungicide applications were initiated on 15 Jul and repeated every 5 to 8 days during the production season for 11 total applications per treatment. All fungicide treatments were applied with a CO2 tractor-mounted sprayer with 3 hollow-cone D4-25, disc core drop nozzles, (1 over the top, 1 one on each side of row at a 45 degree angle) at 41 gal/A and 58 psi. On 14 Aug, bell pepperfruit with anthracnose lesions collected from a commercial field were uniformly distributed across the experiment to act as an inoculum source. All mature pepper fruit from 15 ft of each treatment row were harvested on 15 Aug, 6 Sep and 27 Sep. Allfruit were graded, separated and weighed for statistical analysis. Monthly rainfall for Jun through Sep was 7.39, 5.70, 2.46, and 3.88 in., respectively.
