CONNECTICUT CLIPPINGS Volume 33 No. 3 1929 - 1999 70 th A n n iv e rsa ry S e e in g g ra y s p o ts by Pat Verm eulen — Turf Topics uperintendents in cool-season turfgrass zones once looked to late August as the peak o f their season. With the worst heat dissipat­ ing, they looked to lower temperatures to allow weary grasses, and workers, to recuperate. Last year, that could not have been further from the truth. During much o f August and September, the perennial ryegrasses on courses from the Atlantic coast to Nebraska withered as if S they had been sprayed with herbicide by a vandal. The cause was not a prankster but Pyricularia grisea, a new invader called gray leaf spot. Until recently only a research footnote, it has progressed into an epidemic. Just eight years ago a pair o f Penn State researchers, Dr. Peter Landschoot and Bryce Hoyland, found gray leaf spot on two courses in their state. The disease received scant attention over the next three years because it only June, 1999 caused foliar, or leaf, damage and left mature plants unaffected. Then in 1995, the disease caused devastating losses o f up to 90 percent on fairways and rough. By last sum­ mer, gray leaf spot had spread into nearly 20 states, and now it is consid­ ered a threat for wider infestation. Prior to breeding efforts in the 1960s, perennial ryegrass was a diffi­ cult turf to mow — the end of the leaf would tear instead of cut cleanly — and was not used on many courses. After its improvement through selec­ tive breeding, many courses used it as a permanent monostand.

A number o f courses experi­ enced winter injury due to prolonged ice cover and repeated freeze/thaw cycles. We have had some warm weather this spring, but w e ’ve also had enough cold weather and frost to prevent the turf from really popping. Recovery from winter damage is going slowly at courses that are not using covers, and the b en tgrasses at many courses are still showing the purpling effects of cold temperatures. Root growth observed at courses from Rochester to central New Jersey is w hite and healthy, but the cooler temperatures seem to be postponing the normal flush of root growth. One has to wonder if the weather will turn hot over­ night? The forsythias are early this year, probably due to last sea so n ’s drought. Nonetheless, preemergent herbicides should be going out soon if they aren’t already. We have seen hyperodes w eevil adults out and about, so be sure to scout for them.

It’s a case of an exotic pest pretty much having its way on an important native species. This adelgid first arrived in Connecticut around 1985 from states to the south. I had expected it to move in somewhat slowly, like other invading species have, but the following spring, infestations were cropping up all over the southern coast It was quite the invasion. I started looking into what had been done scientifically with this insect and there was no literature whatsoever, so we started a pretty vigorous research program." Page 4 Continued from paae4 ladybugs in hemlock forests in Bloom­ field, Cheshire, Hamden, New Fairfield, New Hartford, Pomfret, Wash­ ington and W indsor, CT, and in Charlottesville and M ontebello, VA. Our studies are evaluating the poten­ tial o f the ladybug to b ecom e established and to control hemlock w oolly adelgid in the northern and southern ends o f the infestation. This past spring we also provided the New Jersey Department o f Agriculture with a back-up colony o f P. tsugae. P. tsugae is not the same ladybug that appears in large numbers on the sides o f light colored houses in the fall. The ladybug with the annoying aggregating behavior is another Asian species, Harmonia axyridis, which is a much larger beetle, about the size o f a June, 1999 Connecticut Clippings small pea, and mainly orange in color with black spots. P. tsugae is only about the size of a poppy seed and is jet black; fortunately, it does not dis­ play the annoying aggregating behavior o f H. axyridis . Despite its being somewhat o f a nuisance at tim es, H. axyridis is undoubtedly eating huge numbers of aphids and, therefore, is a great benefit to farmers and gardeners. In fact, H. axyridis even attacks hemlock woolly adelgid during the spring, although the adelgid is not a preferred prey. Any natural enemy needs to possess a number o f important attributes if biological control is to be successful. V Its life cycle must be compatible with that of the host V It must be able to disperse in the forest V It must be able to overwinter and survive weather conditions throughout the year and become established V It must find mates and reproduce V It must reduce numbers o f the pest. Our studies thus far have revealed that the Japanese ladybug, P. tsugae, possesses many o f the important quali­ ties o f a successful biological control agent. Indeed, we have found that P. tsugae feeds on all life stages o f its prey and that its life cycle is well synchronized with that o f the adelgid. For example, both insects have two generations each year in the field. Spring egg laying by ladybugs -4 PROFESSIONAL. EXPERIENCED.

A lso, when adelgids are inactive for about 14 weeks during the summer, adult ladybugs are able to survive by feeding on dormant young adelgids. Three or more generations o f P. tsugae can be reared each year in the laboratory under controlled temperature conditions. To determine the dispersal ability o f P. tsugae we hung yellow sticky traps that are attractive to both male and female adult ladybugs in a hemlock forest at various distances from our release trees. In addition, we sampled hem lock branches for beetles by inspecting them or by tapping them with a stick while holding a white sheet beneath to catch the falling ladybugs. W e found that adult ladybugs actively explore branches for adelgids and move off release trees to nearby ones if need be. We have been able to find some on hemlocks more than 100 meters away from release trees during the same season as release, which is no easy task considering that these ladybugs are tiny. To investigate the cold hardiness of P. tsugae in Connecticut and in Virginia, we returned to release sites in April and May in hopes of finding live ladybugs. We were delighted when yel­ low sticky trap catches and sampling o f hemlock branches in spring revealed that adult ladybugs survived the winter in 1995-1996 (an extremely cold, snowy winter) and 1996-1997 and 1997-1998 (both were mild, relatively snowless winters). Several adult ladybugs that had win­ tered over were observed on infested branches that had been broken by snow and had fallen from trees which sug­ gests that ladybugs probably spend the winter in the litter on the forest floor. The ability o f P. tsugae to survive a variety o f winter conditions in both states confirmed establishment and was exciting news because doing so is a major hurdle that any introduced natural enemy must overcome. By examining branches for several hours monthly on release and adjacent trees at each release site, we have been able to document that the ladybug is in fact successfully developing, reproduc- (continued on page 10) GOLF COURSES RELYON BUILT TO LAST, Con Vault’s patented system protects your fuel within a steel primary tank wrapped in a 30 mil poly liner, reinforced within a six-inch concrete vault.

The 18 th hole is the signature hole and was rated the toughest par 4 in Connecticut by the Connecticut Golfer on line Yearbook in 1999. Over the years, the course has received recognition from the Connecticut Magazine being rated the 9th best private club in CT and the 3rd toughest private club in CT in 1997 and 1998. Three golf holes were included in the Bests 18 holes in CT with the 13th (par 5), 17th (par 3) and 18th (par 4). The fairways are wide with 89 sand bunkers throughout the course. Some o f the greens are sloped dramatically and below the hole is the favored loca­ tion from which to putt. The club is working with architect Stephen Kay on a master plan.

Furthermore, in a laboratory, adult fem ales have displayed an uncanny ability to economize their egg laying. They apparently seek out hem­ lock branches with adelgids and then lay a number o f eggs that can be sup­ ported by the number o f adelgids on that branch. Our studies thus far indicate that P. tsugae is significantly reducing adelgid numbers, not only on release trees, but also on adjacent trees. In the first experiment, we released adult ladybugs in June, 1995, onto five infested hemlocks in a Windsor forest. At that time, we placed some infested branches inside nylon sleeve cages to protect adelgids from the ladybugs. We left other infested branches without cages and, therefore, exposed to ladybugs. In May, 1996, we compared the number of adelgids, alive and dead, on branches that were caged and not caged. Much to our delight, we found that adelgids were 88% less numerous on branches that had been exposed to ladybugs than on caged branches which su g g e sts that P. t sugae had significantly reduced adelgid numbers. Unfortunately, the experiment could not rule out the possibility that the cages them selves, had som ehow enhanced adelgid survival, for example, by excluding incidental native preda­ tors or by moderating the microclimate o f the branch. Therefore, we conducted a second experiment at the Windsor site in 1996 and 1997 to determine the impact o f ladybugs on adelgids without the use o f exclusion cages. A new group o f infested trees was selected in a different section of the hemlock forest. Adelgid egg masses present on branches prior to the release of 1,100 adult ladybugs in 1996 and a year later in 1997 were counted and compared. This was done for branches on which ladybugs were actually released and on nearby branches without ladybugs. W e found that 11 months after releasing ladybugs, adelgid numbers had been reduced by 87% on release branches and by 27% on nearby branches on which ladybugs had not been released. The slightly reduced numbers o f adelgids from 1996 to 1997 on this latter group o f branches suggests that some ladybugs may have dispersed from release branches onto -> ........................................... : The Legacy Advantage..

Our studies during 1997 in Bloom ­ field, Hamden and New Hartford, CT, and in Montebello, VA, were equally exciting. Comparison between areas in these hemlock forests where P. tsugae was released and control areas at least 500m away, revealed that adelgid densities had been reduced 47-88% in only five months by a starting population o f only 2,400 to 3,600 adult ladybugs. These same levels o f adelgid reduc­ tion were observed when branches on which ladybugs were released were compared with branches enclosed in cages to protect adelgids from ladybugs. These data confirmed the effec­ tiveness o f P. tsugae as a predator o f hemlock woolly adelgid and dispelled previous concerns that cages them­ selves affect adelgid survival. Successfully establishing P. tsugae in our forests may also have the added benefit o f controlling other adelgids. Our preliminary studies have revealed that this ladybug also attacks and develops from egg to adult on other adelgid pests including balsam woolly adelgid, C ooley spruce gall adelgid, and pine bark adelgid. These and other alternate adelgid hosts help enhance the establishm ent and survival o f P . tsugae in the conifer forests o f eastern North America. entire adelgid-infested area on our own.

The relative unimpor­ tance o f the disease early on meant scientists spent little time studying its management and control. As a result, there are far more questions today than answers. An outbreak becom es apparent with reddish-brown spots on leaf blades, in turf patches about 6 to 8 inches in di­ ameter. Although the symptoms o f gray leaf spot can be confused with other diseases, immediate confirmation o f potential infections by a turfgrass pathologist is important, since entire fairways can become infected within days. Early symptoms are even less obvi­ ous on seedling perennial ryegrass since leaf blades are slender and lesions are invisible to the naked eye. A disti­ nct twisting o f the leaf tip, which causes blades to look like small fish­ hooks, is the easiest way to identify outbreaks. P The good news is that fungicide combinations have proved successful in controlling the disease. The bad news is that anywhere from three to IS applications are required since disease activity cannot be predicted. In addi­ tion, the disease can remain virulent until recurring hard frosts. For courses with tight budgets that have not had to treat perennial ryegrass, fungicide costs o f $20,000 to $50,000 (depending on acreage and conditions) have increased the price of keeping turf alive. This new invader has shown to be a formidable opponent and has, in many respects, humbled the turfgrass indus­ try. The USGA Green Section will keep in touch with researchers and act as a clearinghouse o f information for courses that may be struck by the dis­ ease. Golfers should be aware that gray leaf spot presents new challenges to the turfgrass industry and that taking bold management steps will be neces­ sary to prevent future outbreaks.
