Pests & Diseases

Some of the more panicked calls I receive during summer months are from silage corn growers who have suddenly discovered they have a spider mite infestation in their fields. In many cases, it seems the mites that weren’t there yesterday have multiplied an hundredfold overnight.

The arid climate and open spaces of our Western states create the perfect combination for providing low disease pressure, which allows us the ability to produce high-quality forages.

Newer irrigation systems like drip and subsurface drip irrigation (SDI) have been used by cutting-edge alfalfa growers for quite some time.

The Shenandoah Valley of Virginia sits squarely in the fescue belt. As an extension agent, I hear a lot about fescue toxicosis from the academic side, but rarely does it make its way into the real-world conversations I hear in the field.

The clover root curculio (Sitona hispidulus) is a pest of alfalfa and clover that occurs throughout the U.S. Adults may cause injury by feeding on the foliage of fall-planted alfalfa, but the primary concern is damage caused by larvae feeding on the roots, which can reduce yield, quality and stand persistence in forage alfalfa.

Living in Pennsylvania around this time of year, I hear a lot of talk about Punxsutawney Phil and his shadow.
