How Much Are Resistant Weeds Costing You?

For farmers in the northern hemisphere, it’s about time for planters to start rolling. And while I’m sure your seed decision was made a long time ago, herbicide decisions generally are a wait-and-see prospect depending on what type of spring Mother Nature graces us with.

Today, I wanted to offer a reminder of the economics of weed resistance.

In the US, herbicide costs in the PRE-weed resistance days were about $10-20/acre. But now soybean growers in the Midwest are paying $30-40 per acre where herbicides arn’t working as well. However, if you move down into the southern states, they are spending anywhere from $70-120 per acre to get sufficient weed control.

A portion of that high cost to southern growers is due to the use hand-hoeing crews who come in to cut down weeds during the growing season so the millions and millions of seeds for next year’s “weed crop” don’t scatter during the autumn.

Resistant weeds are definitely on the move. In the US, they are fanning north, east and west. The dreaded resistant Palmer Amaranth is even leaping north to areas in Michigan and Wisconsin because it’s in feed that’s being transported north to dairy farms.

Rotating your crops isn’t enough. The best solution today is to rotate your chemistry and use multiple modes of action.

Here are a few tips from the Respect the Rotation campaign:

  1. Know Your Weeds. Know Your Fields - Identifying weed species will help pinpoint which herbicide program will work best on every acre. Also understand the weed pressure and history within each field.
  2. Start Clean - Effective tillage or the use of a burndown herbicide program can control emerged weeds prior to planting.
  3. Stay Clean - Use Overlapping Residuals - In any weed management program, the goal should be to control at least 80 percent of the weed population with residual herbicides.
  4. Apply Herbicides Correctly - Apply to actively growing weeds. Apply when weeds are no more than 3 to 4 inches. ALWAYS Follow label instructions.
  5. Do Not Allow Weed Escapes - Treat every weed escape as if it is a resistant weed. Consider spot herbicide applications, row wicking, cultivation, hand removal of weeds and other techniques to stop seed production.
  6. Zero Tolerance to Reduce the Seed Bank - Do not allow surviving weeds to set seed in order to decrease weed population shifts from year to year and prevent major weed shifts. OnePalmer amaranth plant can produce up to 1 million seeds per plant in optimal conditions.
  7. Clean Equipment - Avoid moving equipment that has not been thoroughly cleaned.

Bottomline: weed resistance is not going away. And US farmers – don’t think you are alone. This is a global issue, and it’s on the move.

Although the 2012 drought in the Midwest may have dimmed the memories for some of the 2011 Ohio and Mississippi River flood, engineers, landowners, conservationists, crop scientists and soil scientists haven't forgotten.

Weather, Climate Predictions Worth Their Weight in Gold
The economic costs of damaging weather events have an immense and increasing impact on the US economy, and these costs could be anticipated and mitigated by improved weather and climate predictions, say a range of experts in the public and private sectors.

CO2, Ozone Affect Wheat’s Nutritional Quality
Predicting the effects of changing levels of atmospheric gases on agricultural crops is vital to ensuring food security under global environmental change. As well as yield, impacts on the nutritional value of crops must be considered.
