Rose Chafer Beetle

Skeletonizing of the leaves of roses, raspberries, grapes, fruit trees, and many other cultivated trees and shrubs may be caused by the adult rose chafer, Macrodactylus subspinosus (Fabricius). Adult beetles are attracted to flower blossoms, particularly roses and peonies. Damage occurs in June and tends to be most severe in areas of light sandy soil, which is preferred by the larvae. Heavy of clay soils hamper rose chafer growth and development. Click “read more” to view the factsheet.

Fruit Crops – High Spring Temps and Frost

The record breaking temperatures this March have brought all of our fruit crops into full swing about one month earlier than normal. While there were a few management techniques to slow things down for a few days, there is nothing we can do to keep those buds from breaking with the sustained temperatures. All of our fruit crops have broken bud and as they continue to develop are increasingly susceptible to frost damage. In most years, we are not out of the danger of frost until Mid-May, (recall 2010’s mother day frost!) so when making management decisions consider the high possibility of having a reduced crop load this year.
