Weed control in the 21st century: a primer on precision agriculture’s role in improving yield, quality, and

resource conservation

What is a Weed?

Some Rethinking

Decrease resources available -- Water, Nutrients, SunlightDecreases yield / quality

Harvest Issues

Aesthetics

What Weeds Do

Resource Conservation

Resistance

Increased Demand on Production

Issues in the 21st Century

Weeds Decrease Available Resources

Water, Nutrients, Sunlight

Can adversely affect crop -- Up to 60% Loss of Grain Production (Appleby et al. 1976)

Resource Conservation

Precision through Knowledge

Resistance Issues

Crop Rotation

Chemical Rotation

Using labeled rates – NO CUT RATES!

And Knowledge

Rotation is Necessary

New Technologies

WeedSeeker

Precision Application

Application in the 21st Century

WeedSeeker

GIS in Weed Control

Application Issues

Low Drift Systems

Precision methods to determine proper application procedures

Spray Lasers

Labels specify rates

Labels specify timing

Labels are key to applying correctly

Just Read the Label!

Knowledge of a Given Problem

Rotate, Rotate, Rotate!

Implementing new technologies and techniques

Following directions can be key to success
