2014 SUMMARY OF FIELD CROP WEED MANAGEMENT RESEARCH

INTRODUCTION

The experiments summarized in this report are designed to develop data to support extension weed management recommendations for canola, field corn, peanuts, grain sorghum, and soybeans. Additionally, these experiments demonstrate new and/or proven management practices to growers, county extension agents, agribusiness personnel, and other extension specialists.

Replicated experiments are established for specific needs and are located on university stations or private farms. The experiments are a joint effort of the University of Georgia extension faculty, county extension agents, cooperating research personnel, and cooperating growers. Commodity organizations, seed and chemical companies provide financial support of these experiments.

This publication contains results of use patterns of herbicides, some of which may not be registered for the particular use. Such results are included for informational purposes only and should not be taken as recommendations for use. Additionally, the University of Georgia does not guarantee nor warrant the standards of the products, nor do they imply approval of the products to the exclusion of others which may be similarly effective.

The data in this report were analyzed using the Agricultural Research Manager - 9.2014.2 (ARM) computer program.

PESTICIDE PRECAUTIONS

ATTENTION ! Pesticide Precautions
  1. Observe all directions, restrictions, and precautions on pesticide labels. It is dangerous, wasteful, and illegal to do otherwise
  2. Store all pesticides in original containers with labels intact and behind locked doors. “KEEP PESTICIDES OUT OF REACH OF CHILDREN.”
  3. Use pesticides at correct label dosages and intervals to avoid illegal residues or injury to plants and animals.
  4. Apply pesticides carefully to avoid drift or contamination of non-target areas.
  5. Surplus pesticides and containers should be disposed of in accordance with label instructions so that contamination of water and other hazards will not result.
  6. Follow directions of the pesticide label regarding restrictions as required by State an Federal Laws and Regulations
  7. Avoid any actions that may threaten an Endangered Species of its habitat. Your county extension agent can inform you of Endangered Species in your area, help you identify them and through the Fish and Wildlife Office, identify actions that may threaten Endangered Species of their habitat.
