Get a jump on weed management
Peanuts are most effected by direct competition from weeds in
the early season. The first 40 days is when the weed control battle
is won or lost. In the late-season, weeds can cause problems with
digging, and the result is harvest losses.
Use these Tips to improve your weed management program:
• work to obtain a quick emerging, uniform crop
• select herbicides based on weeds present
• control weeds when they are small, preferably when they
are less than 2 inches tall
• conduct maintenance check and calibrate sprayer
• make application under good conditions
• rotate crops to change weed control ability
• limit early-season cultivation, which leads to another
flush of weeds.
Controlling that first flush of weeds is most important and will
reduce the amount of weeds reemerging later in the season. Therefore,
the most critical time for herbicide applications is at-cracking
and very early post-emergence. Being timely with herbicide applications
is the key to successful control of weeds.
The charts on the following pages offer a guide to the effectiveness
of various herbicides on the many weed species that invade peanut
fields. The rankings will change from year to year, based on field
research, so careful study of a herbicides effectiveness against
your weed problem is suggested.
Timeliness, attention to various cultural practices and the proper
use of herbicides is critical for an effective weed management
