Featured Weed of Concern
Convolvulus arvensis

Field Bindweed is one of the most notoriously difficult-to-control weeds in New Mexico. This spreading perennial will start growing back from overwintering rhizomes in early spring.

Depending on temperatures, they may start to break dormancy as early as March or April. This is the ideal timing to try and control invasive perennial weeds, along with fall management as the plant is preparing for winter dormancy. Any period of active growth will result in more injury to the weed and more effective weed management.

For more information, see our Field Bindweed publication.

Featured Weed of Concern
Astragalus spp.

New Mexico contains several species of locoweed. Many locoweed species are toxic to livestock. The incidence of livestock poisoning can increase following a wet winter-spring. Poisonous plants can be some of the few green plants growing early in the year and thereby attract livestock while the warm-season grasses are still mostly dormant.

For Locoweed management recommendations, see Guide B-823: Locoweed Control: Aerial Application or Ground Broadcast.
