Herbicides that work well on buckthorn: Do NOT use more chemical than you need! If a little is good,a lot is not better. 1.0ypjlosate is the active ingredient in Roundup(now off patent),Ortho Basic Solutions Weed&Grass Killer Concentrate,and others.This herbicide is a good choice since it does not leach through the soil.Use it for cut-stump and frill treatments. Many different concentrations are available. Check the fine print in the lower label corner. • 10 to 25% active ingredient is needed for cut-stump and frill treatments+. • Apply to a fresh cut when temperatures are above freezing. • Only 2%active ingredient is necessary for foliar spray(best for seedlings in the late fall). 2.Tryclopyramine is the active ingredient in Garton 3A and Ortho Brush 13-Gon. • Mix with water for cut stump,frill,and foliar applications • Use goggles when spraying,since exposure to this chemical can cause a burning sensation in eyes • For the cut-stump and frill method,apply immediately after cutting 3.Tryclopyr ester is the active ingredient in Garlon 4,Crossbow&Pathfinder. (Pathfinder is ready-to-use.) • Mix with diluent or Kerosene for cut-stump,frill and basal bark treatments • Can be used when the temperature is below freezing No Garton 3a needs to be applied immediately after the cut.Garton 4 can be used long after the cut because it is solvent-based and will penetrate the stump and bark. Tordon RTU is NOT RECOMMENDED because it leaches through the soil,is persistent in the soil,and can affect roots of other plants. Wet Sites: For areas directly adjoining wetlands,ponds,creeks,and lakes,you must use an herbicide labeled for aquatic use, like Rodeo.* This is necessary when working within ten feet of the shoreline. Use the same rates as Roundup, above. *Rodeo is now beyond its legal patent. The glyphosate product may be offered for sale under other brand names such as Aque.Neat. Tim for sprayini in a dense buckthorn thicket 1. In densely infested areas,use a hand-held tank sprayer;backpack sprayers can be difficult to negotiate through the woods. 2. An ultra low volume spray wand(available through"http://www.arborchem.com")can cut chemical use by 75%. 3. Be sure to wear appropriate protective clothing when using chemicals,especially when mixing concentrate. Use neoprene or chemical resistant gloves,not latex,cloth,or leather. Wear goggles or safety glasses when mixing chemicals. Be certain to read and follow label instructions. VVhere to buy the herbicides • Glyphosate herbicides are readily available at hardware stores,Menards,Home Depot,etc. Be certain to look for active ingredient concentration between 10&25%for cut stump and frill treatment uses. • Garton herbicides can be purchased through local agriculture,turf,and horticulture co-op suppliers or wholesalers. BRUSH DISPOSAL OPTIONS 1. utilize:salvage buckthorn for firewood&/or wood-working(trellises,arbors,fences,walking sticks,etc.) 2. Chip:chip brush and spread on trails 6"deep or in the woods 1-2"deep. Not recommendedfor branches with fruit. 3. Cut-slash is to cut up and leave the wood on the ground;wood/soil contact can reduce erosion and create habitat for amp:Libians,small mammals,and insects;aesthetics is a consideration. 4. Cut&haul:check with your garbage hauler or tree service;Minnetonka's resident brush drop at Public Works is open April through mid November. 4. Burn:recommended for branches with fruit containing viable seed;burn permit is required;contact your local fire ma-shal. 5. Brush piles provide wildlife habitat&cover for songbirds,amphibians,and small mammals. Note:Minnetonka Public Nuisance ordinance does not allow brush piles(neatly stacked wood is okay). 6. Energy conversion: District Energy in St.Paul bums wood waste to generate heat&electricity.Some cities have their brush ground and transported there. 6
