Weed Management

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.

Using Herbicides
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 program.
