Managing mites in walnuts

May 11, 2016

PACIFIC SOUTHWEST: Small but mighty, mites can have a damaging effect on walnut crops. Feeding causes stippling and browning of the leaves, which can lead to leaf drop and ultimately reduce nut yield and quality.

According to the University of California Cooperative Extension, managing mites in walnuts takes a sharp eye, monitoring, and predator awareness in the orchard. It’s also important to keep best orchard management practices to reduce populations such as:

  • Minimize dust by oiling orchard roads and maintaining ground cover
  • Keep orchards well irrigated – vigorous trees have reduced mite problems
  • When possible, avoid using pyrethroids, organophosphates, and carbamates until later in the season
  • Utilize a miticide, when necessary

Agri-Mek® SC miticide/insecticide provides uncompromising performance against mite and insect pests. Rapidly absorbed into plant tissue to provide a reservoir of protection, Agri-Mek SC provides proven performance for walnut growers.
