Needle Scale Eggs Have Hatched

Advertisement

Pinyon needle scale eggs have already hatched in Payson (see map).

The immature "crawlers" have emerged from the egg state and have attached themselves to the needles on the ends of the branches.

This is the stage of the insect that initiates the damage to pinyons every year. The crawlers appear as tiny dots on the needles at the ends of the branches.

At this point, it is too late to remove the egg masses, which were laid by the female scales in March.

The crawlers can be chemically treated using an EPA-approved insecticide. The insecticide label should state that the chemical is for treatment of "scale crawlers."

Insecticides used improperly can be injurious to humans, animals, and plants. Follow directions and heed all precautions on the labels. Contact a qualified and licensed professional for the proper treatment of your tree(s).

Consider slow, deep and infrequent watering of the infested pinyons around your home, starting now, with a properly installed and maintained drip system, or with a soaker hose placed around the dripline of the tree.

However, check with the Town of Payson Public Works Department first, for current water restrictions. Continue watering until the "monsoon" rains are well established.
