Japanese adult beetles are emerging and feeding on susceptible plant material. Extremely sensitive plant material includes American mountain ash, evening primrose, Japanese maple, hollyhock, crabapple, and American linden. The feeding of Japanese beetles generally does not overly stress the plants (unless severe defoliation occurs). However, defoliation caused by this insect reduces the aesthetic appearance of the plant material and the landscape. For more information on this insect and possible means of control see:

During this time of the year, difficult to control lawn weeds are more apparent. Clover and violets are often the most difficult weeds to control at this time. Generally, herbicides are needed to eradicate these weeds. The best time for control is autumn but in many situations homeowners demand control now.
