Remember in that high school English class when you had to write a haiku? Three lines, 17 syllables, in a 5-7-5 pattern? In solidarity with all students finshing up their school semester, the Range & Pasture experts of Corteva Agriscience offer up their own haikus for this time of year:
Kill troublesome brush
by penetrating the bark
any time of year!
Cool days encourage
improvements shunned in heat.
Basal spray brush now!
OK, here’s the real point: On most pesky brush species, basal bark spraying (stem spraying) with Remedy® or Remedy Ultra herbicide works year-round, including in the dormant season.
That means you can target brush this fall or winter when it’s cooler to work.
Brush control can’t be much simpler than basal application with Remedy or Remedy Ultra.
The herbicide solution — herbicide and an oil-based carrier — is applied to the bark, not the leaves. You’re not dependent on foliage. The solution penetrates the bark, and most woody plants will move it to the roots. Result: dead brush. (If you do spray green leaves with the oil-based basal solution, the leaves burn and drop too quickly to move the herbicide. Save your money and basal-spray the bark only.)
Use low-volume basal spraying on woody plants with smooth bark (that’s important — easier to penetrate) and trunks less than 6 inches in diameter at the base of the tree. Here’s the mix: 25% Remedy OR Remedy Ultra plus 75% oil-based carrier (diesel fuel or basal oil) — no water. Adding a dye can help you tell where you sprayed.
Apply enough solution to wet the lower 12 to 15 inches of the trunk, but not to the point of runoff. Pretend you’re spray-painting. But make sure the solution wraps completely around the trunk.
That mix and method provide excellent control of elms, locust, multiflora rose, oaks, Osage orange (hedge, bois d’arc), privet, sweetgum and many other species.
If the trunk is more than 6 inches in diameter and rough-barked, control may be erratic. To control woody plants of that size, the better option is cut-stump treatment.
Cut-stump treatment means cutting the brush and spraying the sides of the stump and the outer portion of the cut surface to prevent regrowth. Use the same solution: 25% Remedy OR Remedy Ultra in an oil-based carrier.
