Two Main Goals of weed management. --CORRECT ANSWER--Minimize
weed competition, and yield loss. Other main goal is to limit a weeds
reproductions to reduce weed population in future years.
Describe ways weeds can pose problems in crop production --CORRECT
ANSWER--Compete with crops, Reduce crop quality, interfere with
production, produce chemical inhibitors, Irritate or poison, support insects and
diseases,
What is a grass --CORRECT ANSWER--monocots ( corn)
what is a broadleaf --CORRECT ANSWER--Dicots ( soybeans)
Ways to distinguish a grass. --CORRECT ANSWER--one cotyledon (seed leaf)
