Now is the time to scout pasture and hay fields for Japanese stiltgrass and take note of its locations. This invasive grass is typically seen in wooded areas, but unfortunately has been creeping into fields. Once the seed heads start to form in another month or two, you’ll want to have the mower ready.

A fall armyworm outbreak is occurring throughout Virginia, Kentucky, and Ohio. This week, we received a report of armyworm damage to sod from Maryland’s Eastern Shore as well as residential lawns in Lewes, Delaware. This appears to be one of the most significant armyworm flights in many years. Scout turf, sod, pasture grasses, any late sweet corn that has not yet headed, and when the time comes, small grain and cover crops. Females lay egg masses containing between 50 and 200 eggs, meaning damage can be localized and intense and that it does not take many moths to infest a field. It is important to catch an infestation as early as possible. Larvae consume 80% of their total intake during the last three days of larval development. Often, it is during this period or just after larvae have finished that damage is noticed, occurring seemingly overnight as if an army had stripped the field. It takes about 14-19 days for larvae to mature.

Although fall armyworm (Spodoptera frugiperda) is a native pest to North America and a chronic pest in the southeastern US, reports of fall armyworm activity and outbreaks are unusually high this year. There are numerous reports of heavy fall armyworm activity coming out of Virginia, Kentucky, Indiana, Illinois, Ohio, and other states. In Maryland, there have been cases reported across much of the state so far, including Anne Arundel, Baltimore, Charles, Calvert, Frederick, Howard, Montgomery, Prince George’s, St. Mary’s, and Washington counties. Weather conditions have allowed fall armyworm to flourish this year, so producers are encouraged to be on the lookout for potential problems.

This summer has certainly been hot and dry for many of us, which has reduced productivity of many cool-season perennial grass pastures.

The Maryland Milk Moos (March 23, 2023, Vol. 4, Issue 1) is a quarterly newsletter published by the University of Maryland Extension that is focused on dairy topics related to Nutrition and Production, Herd Management, and Forage Production. In this issue, we focus on antibiotic regulation changes, dietary supplements for cows, and spring weed control for pastures and hayfields.

As things are greening up this spring, you may notice a few not-so-friendly plants popping up around your fields, especially given the milder weather this past winter. If you haven’t already done so, now is the time to scout your pastures and hayfields in search of winter annual and biennial weeds. When it comes to weed control, timing of herbicide application critical and it is important to spray when weeds are most susceptible to achieve maximum effectiveness.

Grass tetany is a condition that occurs when magnesium levels in the blood and spinal fluid become too low to support normal bodily functions. The occurrence of grass tetany is often isolated to the springtime when cattle are grazing primarily lush, rapidly growing perennial pasture. Author: Sarah Potts, Ph.D.; Title: Grass Tetany

Fertilizer prices have continued to climb, with prices increasing as much as 76 to 151% within the last year alone (Figure 1). Current predictions are that fertilizer prices are expected to remain elevated for at least the next six months, putting us well into the next growing season.
