Fall is a good time for weed control

With all of our recent rains, we are sure to get a new, end-of–season flush of growth on many of our most bothersome weeds.

So, from now until the leaves turn, or we get a hard frost, is an ideal time to kill biennial, perennial and some winter annual weeds.

• Deep rooted perennials such as Canada thistle, yellow toadflax, leafy spurge and others have large root systems for nutrient storage.  These plants are pulling nutrients down to their roots this time of year to feed their root system. To take advantage of this action for maximum herbicide effect, apply appropriate herbicides now.

• Seeds from biennial plants such as musk, bull and scotch thistles, common mullein and others are germinating from now until the first frost. Control these weeds by cutting the root below the crown or by using appropriate herbicides. These plants remain low to the ground in rosette stage until next summer when they bolt and flower to make seeds.

•  Seeds from winter annuals like downy brome (cheat grass) also germinate from now until frost. Since these plants normally do not have a strong root system, chopping, pulling or herbicides can control these plants. These are early bloomers so they mature to seed production from late spring to early and mid-summer.

When applying any herbicide, remember to read and follow label directions. This is the law. Pesticide labels are the legal document located on the pesticide container that provides information concerning the safe and effective use of the chemical. The most valuable time spent in pest control is the time you take to read the label.

For information on weed identification and herbicides for your situation, contact the Archuleta County Weed and Pest Control office at 264-6773.
