Simple, ingenious, reusable, non-toxic method of cutworm control. The CutwormShield™ is a 2" long plastic plant stem cover shaped like a big hair curler with a "wing". Squeeze the wings to open the opposite side and slide it onto the plant stem. When wings are released the shield closes to completely cover the stem. This barrier prevents cutworms and other insects from getting to the stem at the soil level. 3/4" dia.
