Effingham AG News
I do not know what happened to January, but February has arrived and it will not be long before
the seed will be planted for the 2012 growing season. Hopefully, the 2012 harvest will be
prosperous for you.
Peanuts and Zinc
Peanuts are fairly sensitive to zinc toxicity. If your soil test indicated 10 lb/Acre zinc, then a zinc
toxicity statement would appear on the soil test report. If you are willing to increase the soil pH
up to 6.5 you should be able to handle about 70 lb/Acre soil test zinc. The table below shows the
minimum soil pH to avoid toxicity at various zinc levels.

Wheat
Aphids can be a real problem in wheat due to the fact that they transmit Barley Yellow Dwarf
disease besides the fact that they damage the plant through direct feeding. We need to be
scouting our fields to evaluate aphid levels. I have listed some information below from the UGA
Pest Control Handbook in regard to aphids.
Inspect fields at 25-35 days after planting, full tiller, and heading. Yield-reducing transmission
of Barley Yellow Dwarf virus can occur during first two periods; transmission at heading is too
late to reduce yield.
Aphid treatment thresholds are:
Seedlings (2 per row ft.)
6-10 inch plants (6 per row ft.)
Stem elongation (2 per stem)
Flag leaf (5 per flag)
Heading (10 per head to include flag) and Soft/Hard Dough stages (Do not treat)
Pasture and Hayfield Weed Control
Look at your forages to determine the severity of weed pressure. To control many of the winter
weeds, they need to be sprayed in February or early March. The weeds need to be sprayed
before they reach 3-4 inches in height to attain maximum weed control.
2011 Variety Performance Tests
Included you will find the Effingham County corn, cotton and soybean research results. Thanks
to the producers that allowed this information to be generated on their farms. This information
can be helpful and useful to you in making your 2012 variety selections. The UGA CAES
Statewide Variety Testing program provides annual performance testing results on several
commodities including small grains and forage, corn and silage, and field crops. The statewide
OVT trials are available at the following web site - http://www.swvt.uga.edu/
