Fall is a Good Time to Test Your Soil for SCN

Is your yield monitor indicating low yielding areas in your soybean field? Soybean Cyst Nematode (SCN) could be the problem. Get to the root of the problem by testing your soil for the soybean cyst nematode. SCN management starts with a soil test to determine the presence or absence of this nematode in the soil. Absence may indicate either the SCN has not established in the field or could be present in non-detectable levels.

Managing Wheat Curl Mite

Wheat curl mite is one of the more difficult pests to manage in wheat. This is in part due to the limited options available for preventing populations from infesting a field and rapidly reproducing.

Wheat Streak Mosaic Virus Management: Plan ahead before planting this fall

Have you had a history of moderate wheat streak mosaic disease in your field? Do you plan on planting wheat into wheat stubble or wheat fallow? Have your neighbors had wheat streak mosaic disease outbreaks in the recent past? If you answered yes to any of these questions, you need to incorporate wheat streak mosaic control principles into your management plan before planting winter wheat this fall.

Forecasted Cold Temperatures Can Be Used To Cool Down Stored Grain

If temperatures are forecasted as being well below freezing, it would probably be a good time to start thinking about cooling stored grain. Cooling grain reduces the activity of stored grain insect pests and suppresses any mold growth that may otherwise occur.

Scouting Wheat Fields

Scouting is the process of monitoring fields and crops during a growing season. It can provide producers with field specific information on pest pressure and crop injury.

Brown Wheat Mite Affecting South Dakota Wheat

Recently, there have been reports of brown wheat mites throughout central and western South Dakota. The brown wheat mite is generally more of an issue in the drier parts of the state, or in areas experiencing drought. The feeding injury caused by these mites leaves white or brown spots that are referred to as stippling.
