Chemical Mowing Rates

I have had a few calls about rates for chemical mowing applications. Even though the new growth of Fraser fir is out and seems to be hardening up, I would caution going back up to a full 8 oz. per acre rate of RoundUp at this time. You may want to stick to the 4 oz. per acre rate for another couple of weeks if you have fields that need spraying right now.

Summer Pest

Now is a good time to be scouting for a couple of pest. We are seeing some spruce spider mite activity with this hot, dry weather. Be on the lookout for spruce spider mites, especially in fields with little groundcover or along dusty roadways. Also, last week I looked at some trees with Elongated Hemlock Scale and they are producing the white covering right now and are easy to spot. Look on the underside of branches and make plans to treat in late July or early August if you find them.
