About this page |
| There are currently 2 different types (known as 'biotypes') of herbicide resistant weeds in New Mexico. The first herbicide resistant weed reported from New Mexico is Kochia (Kochia scoparia) with resistance to sulfometuron-methyl, reported in 1988. Local weed scientists estimate that there are sites and more than acres infested with herbicide resistant weeds in New Mexico and they infest orchards, railways, and roadsides. The most widespread resistant weed of New Mexico is Palmer Amaranth (Amaranthus palmeri), which infests an estimated 51-100 acres and is found primarily in orchards. Palmer Amaranth (Amaranthus palmeri), with resistance to glyphosate is the most recently discovered (2007) new type of resistant weed in New Mexico. |

FACT SHEETS AND OTHER LITERATURE | Format | | | | Weed Management in Chile.
Richard D. Lee and Jill Schroeder (1998)
New Mexico State University - Circular 548
Taking time to learn weeds commonly found in the
fields will aid growers in making correct management
decisions. Whether it translates to the use of a particu-lar
herbicide or to growing a different crop, weed identification
is the first step to managing weeds in chile
effectively.
When developing a management plan, be sure to
consider all the available management options. Using
all the tools in an integrated fashion will greatly
improve the chances for effective weed management.. | PDF | | | | Weed Management in Pecans.
Richard D. Lee (1999)
New Mexico State University - Guide H-632
Weed competition can reduce growth in a new
orchard 50% or more, and kill pecan trees where spot
infestations are out-competing young struggling tree
seedlings for the available sunlight, moisture, and
nutrients. It has been reported that the maximum
affect of competition is most threatening to an orchard
during the year of transplanting. The second year, this
threat is reduced, and by the third and fourth year,
harm from competition may be minimal.. | PDF |
