I went out to walk my orange dog this morning and wound up with orange shoes. And no, the orange dust all over my shoes was not orange dog dandruff, but masses of rust spores.

Cleaning-up Severe Crabgrass Infestations
By Jim Murphy
Use crabgrass rake to remove
crabgrass infestations in small areas.
If you’ve experience the number of rains that we have in New Brunswick, you are probably seeing plenty of crabgrass. Weather conditions have been ideal for crabgrass in many areas of the state.
You may be asking what can be done to clean-up this weed problem and reduce the impact on renovation practices that you may want to implement at this time of the year. [Read more…]

Green Kyllinga Found in North Brunswick
By Jim Murphy
Uh-oh! We now have green kyllinga at Hort Farm No. 2 in North Brunswick. Joe Clark found it in a field that was sprayed with glyphosate. Most everything died but the kyllinga! Carrie Mansue has made some collections of kyllinga and will be doing some herbicide tests in the greenhouse this winter to determine which materials have the best activity on the this very difficult to control weed.
Keep a lookout for this weed, if left alone it will spread by rhizomes. Carrie has visited lawns that were essentially overrun by kyllinga. Once kyllinga achieves that level of dominance, control is nearly impossible without complete renovation. See previous post on the topic.
Live patch in foreground is kyllinga that survived a spray with glyphosate. Yellowed plants to left are yellow nutsedge.

Rust Never Sleeps
Happy Labor Day, which was yesterday of course, but I had the day off and hope you did too, and were out in your garden enjoying the diseased and insect riddled plants.

… summertime gonna come and go by and by. As the weather changes from the dog days of summer to a more “fall-like” pattern, I am feeling pretty good; but so is the fungus that causes dollar spot.

Oak Lace Bug Symptoms Have Bark, But They Have Little Bite
During the weeks of summer, the symptoms caused by Oak Lace Bugs (Corythucha arcuata) can be a concern to some landscapers & nurserymen. Often times, the infestations are most pronounced on white oaks. From a distance, the stippling of leaves from this piecing-sucking insect can produce symptoms that are similar to those from oak spider mites or classic leaf scorch. Closer inspection determines the identity of the pest.
