It’s that time of year when the yew (pronounced like the letter “U”) is likely in need of a trim to look best as a landscaping plant. Yews have been used as a common landscaping shrub or small tree for decades. They have closely spaced, glossy, rather tough, dark green, linear pointed-end leaves that are 1.5 – 2 inches long. Hard-to-see male and female flowers are found on separate plants and form fleshy red to yellow fruits that contain a single seed.
Many plants have poisonous compounds that can cause all kinds of concerns, and even death, if consumed. The interactions that I have had with veterinarians, suggest that the yew is right at or near the top of plants that cause livestock death. A disheartening scenario is when yew trimmings are thrown over the fence by the livestock owner or neighbor thinking that the trimmings would make a great snack for the livestock. Fresh or dry trimmings, it doesn’t matter. The result will be the same – death.
Yews are hardy perennial landscaping plants, but don’t toss the trimmings to your equine, heard, or flock or they won’t see the light of the next day.
In memory of livestock that met “Their Maker” because they ate yew.
Recently, there have been reports of sick or dying birds found around Ohio and in nearby states. These birds often have swollen eyes, discharge from their eyes that may appear crusted, or a lack of clarity to the eyes. Affected birds may also exhibit neurological signs, for example their head may hang to one side then flop to the other side. In the above photo, taken last week by Kristi Anderson and posted to the Preservation Parks of Delaware County Facebook page, an American robin is displaying symptoms of the illness.
In late May of this year, wildlife biologists in Washington D.C., Virginia, Maryland, and West Virginia began received reports of sick and dying birds. Since then, reports have surfaced in additional states, including Ohio. Ohio counties experiencing the bulk of the outbreak so far include Brown, Butler, Clark, Clermont, Delaware, Franklin, Greene, Hamilton, Montgomery, and Warren counties.

Hay and haylage crops are grown on just over 1 million acres in Ohio (NASS, 2019) and are grown on more Ohio farms (44% of all farms) than any other crop (Becot et al., 2020). In addition, there are over 1.3 million acres of pastureland on nearly 39,000 farms (50% of all farms) in the state of Ohio (NASS, 2017). Fertilizer costs represent 40% – 60% of the variable input costs of forage hay production (Ward et al., 2016, 2018), and so managing these costs is key to an Ohio forage producers’ ability to stay competitive. Furthermore, water quality issues in the state underscore the need for Ohio farmers to manage on-farm nutrients as efficiently as possible. A farmer’s ability to find this optimal balance between meeting crop nutrient requirements without over-application is highly reliant on the best available information. Continue reading
Recent conditions in some areas (soaked soil, fog- and dew-filled mornings, high daytime humidity) can give a different impression about the season so far than weather data at https://www.oardc.ohio-state.edu/weather1/ and various forecasts. Temperature, rainfall, and other data are collected around the clock at OSU vegetable (and other) research sites in Fremont, Celeryville, Wooster, and Piketon and have been for decades. So far in 2021, these four locations have accumulated less precipitation and more growing degree days (GDD) than their historical averages. Also, climate and weather authorities reported on June 11 that the Upper Midwest, including Ohio, is set to experience hot, droughty conditions. Most agree that a dry year is less problematic than a wet one — provided irrigation is possible. However, it can be difficult for vegetable growers to escape the unwanted effects of excessively high temperatures. A way to separate potentially minor, moderate, and severe heat stress, example effects of moderate-severe heat stress, and main strategies for mitigating heat stress during production are summarized below.

During drought and other poor environmental conditions that reduce forage growth, there are concerns for poisonous weeds in pastures and hay. Livestock may be forced to graze on weeds that normally they would not, or they may eat weeds out of curiosity. Scout your pastures and remove these weeds before they cause livestock health problems. Keep in mind there are numerous poisonous plants that could invade an area or pasture. Many plants contain potentially poisonous substances that may be toxic to livestock if consumed. In addition, certain plants may be problematic because of mechanical irritation when eaten, photosensitization, and disagreeable tastes or odors in meat, milk or milk products. If you suspect livestock poisoning, call your local extension educator or veterinarian immediately. If death occurs, the stomach contents should be examined for consumed herbage. Identify the suspected plants and remove livestock from the grazing area until all poisonous plants have been removed or destroyed.
