This week's W**d of the Week is not as scary as it sounds...but it's almost Halloween...
Let us introduce you to Hemlock! First off, this w**d is poisonous to humans and animals - so Beware and take care!
This poisonous w**d can be found in Carson City, Douglas, Elko, Lander, Lincoln, Lyon, Nye, Storey, Washoe and White counties. It often infests fields, waterways, roadsides and waste areas. Its a biennial plant which reproduces by seed and is HIGHLY TOXIC to humans and animals if consumed!
This w**d can grow up to 10 feet tall, is green with purple spots, is stout and hollow, except at the nodes. Its leaves are triangular and fern-like. The foliage has a musty odor and grow to 12 inches in length.
Its flower is small and white and is arranged in umbrella-like clusters at the end of the stalk.
It has a deep and thick taproot which can only be controlled through repeated mowing or tillage prior to seed production. Hand-removal by cutting the taproot below the crown can be effective, but make sure to avoid any contact with the skin!
Other ways to control this poisonous w**d is through insect biological controls, as well as 2, 4-D, chlorsulfuron, glyphosate, metsulfuron or triclopyr to actively growing plants or aminopyralid, imazapic or imazapyr preemergence on young plants.
