I have been out scouting some timothy fields the last few days and have been seeing quite a few timothy field with infestations of cereal rust mite. Many growers have been reporting cereal rust mites in their timothy. Remember that this pest can reduce both yields and quality of timothy hay. Remember to take a look at your timothy fields. As we have said before if your timothy field looks like it is experiencing drought stress symptoms you probably have cereal rust mite. With all the rains we have had timothy fields should not be under drought stress. There is a Rutgers NJAES Cooperative Extension fact sheet that provides more information on cereal rust mite in timothy hay.
