I saw potato leafhoppers today for the first time this year. Potato leafhoppers tend to feed on the undersides of terminal leaves, causing the leaves to cup and turn yellow. In mature trees this is not a problem. The potato leafhopper feeding also slows down the shoot growth and this can be a problem on newly planted trees. Check your young trees for leafhoppers. Leafhopppers can be controlled with Sevin, Thionex or Provado.
