Nitrogen source and anthracnose control

Several anthracnose specimens arrived in the lab these past few weeks, so we thought it was a good time to remind you of the importance of nitrogen source in dealing with this disease.

Previous research has shown that application of low rates of nitrogen can significantly reduce anthracnose damage on poa greens. But are some forms of nitrogen better than others for this purpose?

The answer is definitely yes, as Rutgers researchers Chas Schmid, Bruce Clarke and James Murphy found…
