Grub Control Treatment in your Lawn should happen NOW

This has been one of the most prolific seasons for Japanese beetles (Popillia japonica) in Ohio for many years.  High localized populations were observed throughout the state.  Adult populations of both the Northern Masked Chafer (Cyclocephala borealis) and the Southern Masked Chafer (C. lurida), two of our other common “white grub producing” beetles, were also very high this season.

Of course, high adult populations of these beetles do not necessarily translate into damaging white grub numbers.  Both the chafers and Japanese beetles lay dehydrated eggs that must absorb water from the soil in order to develop, so wet soil conditions support a greater egg hatch which means more white grubs.  Unfortunately, we experienced those conditions in many parts of the state.

Spotted Wing Drosophila Remains a Concern for Fruit Growers

SWD larva feeding on a raspberry

Spotted wing drosophila (SWD) is a fruit fly that over the past five years has become a significant pest of fruit crops such as strawberry, raspberry, blackberry, blueberry, grape, peach and plum. This insect causes damage when its larva – tiny white worms – feed on and within ripening fruit.

Beginning in early June throughout Ohio a number of county OSU Extension offices regularly monitor for the presence of SWD on several fruit farms. By the third week of June this year SWD had been detected in Clinton, Franklin, Greene, and Wayne Counties. Similarly, small fruit growers who have fruit that is ripe or near ripening should also be Continue reading

Tomato Diseases in the Garden
