Abstract

The experiment was established at the Kimberly Research and Extension Center on 3 Jun. The field had been in winter
wheat (Triticum aestivum) in 2003 and was furrow irrigated. Soil type was Portneuf silt loam (20 -74-6% sand-silt-clay and
pH 7.9). Seed treatments were applied as a slurry (12 fl oz/100 lb seed) on 14 May at the rates indicated in the table below.
Experimental units consisted of 4 rows spaced 22 in. apart x 25 ft long, and were arranged in a randomized complete block
design with 4 replicates. At planting the minimum and maximum soil temperatures at 2 in. depth were 59 and 84°F,
respectively. Fertility, weed and insect control, and irrigation management were consistent with common commercial
practices. Stand counts were recorded on 11 Jun and 16 Jun at late -emergence and primary leaf stages, respectively. Roots
from 10 plants were collected from border rows in each plot on 16 Jul when all plants had at least one open flower. The
plants were evaluated for root rot on a scale of 0-4 (0 = none; 4 = severe root rot). Beans were cut on 24 Aug and dried on
the soil surface until they were threshed on 1 Sep with a belt thresher. Beans were screened through a 9/64 in. slotted
screen to eliminate debris and culls and weighed to determine yield. Data were analyzed using the general linear model
procedure (Proc GLM) in SAS. Fisher's Protected LSD was used for mean comparisons.
Yields in the field were below average and not significantly different. Dynasty delayed emergence in the first stand
count since treatments with this product had fewer plants than the untreated check. In the second stand count 5 days later
there were no differences in stand between treatments. All treatments with mefanoxam and fludioxonil (Apron XL plus
Maxim or ApronMAXX) had reduced root disease severity.
