Interested in $10 corn and $30 soybeans for certified organic, but not sure how to transition?
Organic grain production is promoted for greater potential profits with premium grain prices, improved soil health with organic inputs and fewer environmental hazards in the absence of synthetic chemical use. However, the three-year period required for organic certification is a challenging phase when transitioning farmers are learning to do without synthetic chemical manage soil fertility, weeds, diseases and pests, while not yet receiving those attractive premium prices (Delate and Cambardella, 2004). Organic grain production, if done regeneratively, may reduce environmental impacts and increase ecosystem services from agriculture. Among the latter, minimization of nutrient loss to water is especially important in Maryland, since a good deal of the nitrogen and phosphorus pollution to the Chesapeake Bay comes from agriculture (2025 Watershed Implementation Plans (WIPs)). However, the change in environmental impacts due to the transition from “conventional” to organic farming could be either positive or negative (Bavec and Bavec, 2015), depending on the system of practices (inputs, soil disturbance, soil cover, etc.) utilized in the conventional and organic systems (Röös et al., 2018).

2021 Forage Performance of Cereal Cover Crops in Maryland
Dairy farmers are constantly looking for sources of forage to meet their feed needs. One source that many of our region’s dairy farmers utilize is the fall planting of cereal grains that are green-chop harvested the following spring. Among the cereal species used for this purpose are rye, triticale, barley, and wheat. Per the Maryland Cover Crop Program guidelines, cereal grains planted as a cover crop prior to November 5 and suppressed via green-chop in the spring are eligible for the grant payment for participation in the Cover Crop Program. In addition, per the Nutrient Management Regulations, a fall application of dairy manure is allowed to a field planted to a cereal cover crop.

Herbicide Spray Tank Check Charts for Corn and Soybean
As planting gets underway, it is important to stay on top of our most troublesome weeds. In particular, marestail/horseweed, common ragweed, and Palmer amaranth. Below are two new charts to help determine the type of products to be included in the tank mix to best manage these weeds in corn and soybean.

Corn Earworm Trap Captures Up, and New Web Page for Updates
A few hot spots where corn earworm (also known as tomato fruitworm, soybean podworm, and sorghum headworm) activity is starting to rise have been identified in central Maryland. The relatively mild 2020-2021 winter allowed adult moths to overwinter in Maryland, and some parts of the state experienced a higher than normal first flight in early June.

Summary of the Comparative Efficacy of Common Active Ingredients in Organic Insecticides Against Difficult to Control Insect Pests
There exists a lack of control efficacy information to enable decision-making about which organic insecticide product works best for a given insect pest. Here we summarize results of 153 field trials on the control efficacy of common active ingredients in organic insecticides against groups of the most difficult to control insect pests. The performance of organic products Entrust (spinosad), Azera (pyrethrin and azadirachtin), PyGanic (pyrethrin) and Neemix (azadirachtin) varied widely among pest groups, as well as among pest species within a group, providing an overall reduction in pest infestations by 73.9%, 61.7%, 48.6% and 46.1%, respectively.

Be On Lookout for Tar Spot: A New Disease of Corn
Before anyone panics, this disease has not been confirmed in Maryland; however, it is close by and could potentially spread to our state. As you’re scouting fields this summer, keep this one in the back of your mind. Tar spot is a fungal disease of corn caused by Phyllachora maydis. It was first discovered in the United States in 2015. In Latin America where tar spot is more common, another fungal species, Monographella maydis, is known to occur in complex with P. maydis; however, only P. maydis has been found in the United States.
