RODENT PROBLEMS & SOLUTIONSMolesGophersThere are two kinds of molesin Minnesota: the easternand starnose mole. Moles arecharacterized as small rodentswith pointed noses, large clawed,paddle shaped front feet andbulky hairless tails. Moles feedprimarily on beetles, grubs, andother insect larvae. Damagecaused by moles is noticeable bythe elevated tunnels they create.Their damage to turf can besevere with large mounds andtunnels through large acreage.They can grow to 8 inches, canstand upright and are obviousfor their plump cheeks whichcan carry both food and nestingmaterials. Because most of theirnetwork is underground, theycan disrupt irrigation systemsand cause soil erosion.Shrews (Shrewmouse)SquirrelsShrews are rodents that range insize from 1-5 inches. Six species ofshrews exist in Minnesota and areidentified as a drab gray or browncolored animal, with longer pointynoses. Shrews don’t cause a lot ofdamage to lawns or interiors.We all know that they can easilywreak havoc on planters as wellas any garden crop or bulbsunder the surface. But becauseof their burrowing tendencies,they can play a role in lawndestruction as well.VolesSimilar to the mice found in yourhome. They are known as a fieldmouse with fur in brown/ greytones, small round bodies andbeady eyes with a long tail. Thedamage they inflict is generallyabove ground by gnawing atedibles and ornamentals. Trailmarks as the snow melts are suresigns of them.Rodent SolutionsThe most important thing to remember when controlling them, is to catch the infestationas soon as possible. Like rabbits, all rodents can populate quickly and once established,they are difficult to exterminate.A first step is to apply a Grub Control product to eliminate their food source. Secondly, wehave repellent productsMoleGo, orMoleMax that can deter them in anon-poisonous way. They use castor-oil based formulas that coat the insects which aretheir food source and steers them away. We also stock other repellents that are scentbased such as Repellex which are seasonal and is absorbed into plants themselves todiscourage gnawing that can occur. Other alternatives are garlic-based scent spikes orelectronic spikes which emit pitch that forces them elsewhere.If none of this works, you will need to implement poison methods or below groundtrapping. Poison control is generally in pellet form and goes right into tunnels for molesand gophers. There are also edible poison worms which are poked into the turf and theneaten as a baited food source. Smoke bombs can be utilized in tunnels which asphyxiatesthem. A last alternative are harpoon traps with spikes that impale them in tunnels and areusually motion sensitive to pathways underground. These are certainly safer for householdpets that might stumble onto the poisons.9651.450.1501 gertens.com

It has a distinguishable triangular stemand is brighter green in color. Yellow nutsedge typically grows in July and August and iscapable of outgrowing fescues and bluegrass. Its roots carry small nut seedlings, whichperpetuate its overtaking of natural grasses.Solution:Yellow nutsedge and other sedges can be controlled, withControl, andSpreader Sticker.NutsedgeProblem: Creeping BentgrassAggressively produces horizontal stems, called stolons, that run along the soil’s surface.These allow creeping bentgrass to form dense stands under good growing conditionsand out compete other grasses, thus becoming a troublesome weed in a lawn.Solution:Creeping Bentgrass can be controlled, with Meso 4SC Select (Tenacity) by Select Source.JRK Weed & FeedFertilome Weed Free Zone,Weed-Out & Nutsedge ControlHi-Yield Killzall Meso 4SC Select& Spreader Sticker(Tenacity)Gertens Turf Handbook10

SOLUTIONS TO SOME OF THE MOSTCOMMON WEED PROBLEMSProblem: ThistlesThistle can be a problematic perennial or biennial weed in Minnesota.Depending on the variety of thistle, it can produce seed once a year or onceevery two years.Solution:Thistles can be quickly controlled with selective broadleaf herbicides, likeWeed & Feed,Weed Free Zone,Weed-Out, Monterey ThistleDown, orWeed Beater Ultra.Problem: PurslanePurslane is an annual weed that reproduces prolifically by seed. Purslane isfound more in areas where the ground has been disturbed, such as flowerand vegetable gardens. The leaves and stems are fleshy and succulent and areoften tinged slightly red.Solution:Purslane can be quickly controlled with selective broadleaf herbicides, likeWeed & Feed,Weed Free Zone,Weed-Out orWeedBeater Ultra.Problem: DandelionsDandelions are perennial weeds that have unmistakable yellow aster-likeflowers. Dandelions will flower in the spring and fall and should be controlledduring these time frames.Solution:Dandelions can be quickly controlled with selective broadleaf herbicides, likeWeed & Feed,Weed Free Zone,Weed-Out orWeedBeater Ultra.Problem: BuckthornBuckthorn is considered a noxious weed because of its invasive capability. Buckthorntwigs are tipped with a short sharp thorn and are easy to identify in the landscape.The leaves are dark green with curved main veins. The berries are black, usuallypersist into winter and contain several seeds.Solution:Because its root systems are so quickly invasive, Buckthorn should be dealt withsooner rather than later. Gertens is a preferred vendor for the ExtractigatorTM whichis a manual lever tool designed specifically for Buckthorn. Otherwise, because it is awoody stem, it has to be destroyed with a root killer such asBrush & StumpKiller. To work effectively it needs to be brushed onto an open fresh cut and absorbeddown into the stem. This works well in Fall while the roots are actively growing priorto winter hibernating. It can then be easily yanked out come Spring.JRK Weed & Feed11Fertilome Weed Free Zone, Weed-Out& Brush & Stump Killer651.450.1501 gertens.comBonide Weed Beater Ultra

soil and add soil amendments. Rototill soil to a minimum of 6 inches. Loosening the soil breaks up compaction, allowing the grass seedlings to root and the grass to take up nutrients and air, while giving better seed/soil contac. Sandy t or heavy clay soils need o t be amended. Grass needs good drainage and soil o t gorw and thrive.
