The following chart is a summary of data across three
locations, Carrington, Langdon and Garrison, ND.
Cultivars tested were
Munich at Carrington, Plaza at Langdon, and Monroe durum at Garrison.
Researchers
were Kent McKay, North Central Research Extension Center,
Minot; John Lukach, Langdon Research
Extension Center, Langdon, and
Blaine Schatz, Carrington Research Extension Center,
Carrington.
Results indicate that FHB (scab) field severities were
signifcantly reduced by all fungicide treatments.
DON levels
(vomitoxin), were reduced by fungicide treatment, but not significantly
so. Leaf diseases were
predominately tan spot and Septoria species and
they were reduced significantly by the AMS treatment.
Yields were
significantly improved by all fungicide treatments as were test weights.
The greatest yield increase
was achieved with the AMS experimental
product.
Folicur fungicide will have a Section 18 for use on wheat
and barley in 2002. AMS 21619 is an experimental
product from Bayer and
will NOT be registered in 2002. BAS 505 is an experimental product from
BASF and
it will NOT be registered in 2002.

forward backward nozzles, in 15-20 gpa
