Midsouth soybean producers will be
able to better manage herbicide resistance while setting the
stage for high yield potential with the new Roundup Ready®/STS™
stacked-trait soybean varieties from
Delta and Pine Land
Company (D&PL).
“We’re excited to offer five soybean varieties that can
contribute toward better weed control in fields where
glyphosate-resistant weeds are a problem, while mitigating
against the development of resistant weeds in fields where
resistance isn’t currently a problem,” said Rick Rice, D&PL
marketing director. “And these varieties all come with top-end
yield potential so a farmer doesn’t have to sacrifice yield in
order to gain the weed control benefits associated with the
stacked-gene technology.”
With D&PL-brand Roundup Ready/STS™ soybean varieties, producers
can apply Roundup®-brand agricultural herbicides in conjunction
with DuPont™ Synchrony® XP herbicide in an over-the-top
application. While Synchrony® XP is labeled for over-the-top use
in non-STS™ soybeans at the rate of 0.375
ounces-formulated/acre, Synchrony® XP can be applied
over-the-top of D&PL-brand RR/STS™ beans at a rate of up to
1.125 ounces of formulated product/acre. The higher rate
improves post-emerge control of glyphosate-resistance weeds such
as marestail and pigweed, while also providing potential
residual activity.
“Synchrony’s second mode of action delivers enhanced post-emerge
activity and potential residual control while helping in the
long-term battle against herbicide resistance,” said Rice. “But,
it requires the stacking of the Roundup Ready and STS™ traits
together in the same plant to be able to use the high rate of
Synchrony® XP in an over-the-top tank mix with Roundup.”
D&PL has very good supplies of both DP 4919 RR/S and DP 5115
RR/S, two stacked-trait varieties with excellent histories of
high yield performance in the Mid-South, especially in the North
Delta regions of Missouri, Arkansas and Tennessee.
DP 4919 RR/S, a late-Group IV variety, is a progeny of DP 4748
S, which has been a high-yielding line throughout much of the
Mid-South. Across many locations in 2006, DP 4919 RR/S
demonstrated chart-topping yields in university and D&PL
testing. It showed particularly good performance potential on
light to sandy-loam fields with irrigation, said Dr. Kelly
Whiting, Soybean Agronomist at D&PL.
“DP 5115 RR/S is an early Group V variety that demonstrated
extremely high yields when planted on good-producing irrigated
fields,” said whiting. “Both of these varieties were bred for
the Midsouth region and both have demonstrated outstanding
performance potential.”
D&PL will also have a supply of seed for DP 4888 RR/S and DP
5335 RR/S, two new varieties with impressive testing results on
clay-type soils. An introductory supply of DP 4112 RR/S, an
early Group IV variety, will also be available.
“The five D&PL Roundup Ready/STS™ soybean varieties were bred
specifically for performance in the southern soybean-growing
regions,” said Whiting. “They have each demonstrated great
potential for top-end yield performance and with the
stacked-gene technology, you get an expanded range of weed
control with added residual protection from broadleaf weeds.
Anyone experiencing control challenges with the Roundup Ready
system alone should give D&PL Roundup Ready/ STS™ soybeans a try
in 2007.”
D&PL Roundup Ready/STS™ soybeans are available from all D&PL
soybean suppliers. To place seed orders, call Customer Service
