|How is the best way to eradicate or get rid of poison ivy? After or during the growing season, or at both times?
|Other than grubbing it out by hand, two herbicides are effective against poison ivy: triclotyr and glyphosate. Triclotyr can be purchased under several trade names, including Crossbow. Use it on a day when the temperature is 70 degrees or cooler. Glyphosate is also sold under multiple trade names, including Roundup. It is most effective in late summer or fall. Both herbicides biodegrade in the presence of sunlight and air and neither travels far in the soil. So, if you're going to use an herbicide, Crossbow or Roundup are effective and not considered harmful to the environment. Best wishes with your eradication project!|
