Weeds Controlled
Cropping/Staging

Preharvest is the best time to treat perennial weeds. In early fall, perennial weeds are moving nutrients down into their roots and rhizomes in preparation for winter. This is the moment when they are most vulnerable and the best control is possible. As always, Roundup brand herbicides give you the best performance along with the most choices at preharvest.

Control
For the outstanding performance that you have come to know and trust, Roundup Ultra™ gives you better perennial weed control than any ordinary glyphosate product.

Power
Roundup WeatherMAX™ gives you power, with the best Canada thistle control, plus quackgrass, dandelion and toadflax - for a year or more after application, plus season long control of perennial sow thistle. You'll thoroughly and evenly dry down both the crop and the weeds, for a faster, easier harvest.

Why Pre Harvest?
From harvest management to quality preservation, a preharvest treatment can benefit this year's crop in so many ways:

  • Earlier combining.
  • Eliminates swathing in some crops.
  • Faster, easier harvesting.
  • More uniformly ripened crop.
  • Thorough weed drydown.
  • Higher crop grades.

Preharvest is also your earliest opportunity to control the weeds that will compete with next year's crop seedlings. With preharvest treatment, you're eliminating these weeds before they have a chance to steal moisture, nutrients and yield.

A preharvest treatment can provide unique benefits to next year's crop:

  • The most effective, economical control of Canada Thistle.
  • Outstanding control of other tough perennial weeds.
  • Complete cropping flexibility.
  • Faster, cleaner crop next spring.
  • Bigger yields next fall.

What's Your Return on Investment?
How much can Roundup WeatherMAX contribute to the productivity of your farming operation? Farmers who use them know they are getting a lot of value - both this year and next year too. You can use the chart below to estimate the value of a preharvest treatment on your farm.

Roundup Pre Harvest: Add Up the Value
Preharvest treatments with Roundup Transorb or Roundup FastForward can give you value many ways this year and next year. You may not get every benefit on every crop every year, but there's no question that it pays for itself over and over.

Value In the Year Of Application

  • No swathing
  • Faster combining due to crop and weed drydown
  • Longer combining days
  • Harvest begins sooner
  • Less equipment wear
  • Reduced shattering
  • Crop is in the bin faster
  • No green seeds
  • Better grades

Value In the Following Year

  • Quackgrass control
  • Canada Thistle control
  • Perennial Sow Thistle control
  • Dandelion control
  • Winter Annual control
  • Other Perennial control
  • Yield advantage from eliminating early season weed control
  • Cropping flexibility due to no herbicide residual
  • Flexibility to choose annual weed control
  • Better timing of seeding operations for optimum yield

Key Assumptions Used to Add up the Value

  • Your results will vary depending on crop treated, weather conditions, degree of weed infestation, etc.
  • Average wheat yield of 35 bu/acre at $4.00/bu
  • Average canola yield of 25 bu/acre at $6.00/bu
  • Weed control value based on 20% yield loss due to moderate infestations of weeds like Canada thistle or Quackgrass. Source: Monsanto research data.
  • Preserving crop quality value based on additional $10/Tonne for better grade.

Improving Harvest Management and Preserving Crop Quality
No matter which Roundup brand you chose - Roundup WeatherMAX or Roundup Ultra - a preharvest application can improve harvest management and preserve crop quality in many ways.

A more uniformly ripened crop

  • Fewer green seeds in canola.
  • Better grades.
  • Earlier harvesting.
  • Elimination of swathing in some crops.
  • Easier timing of swathing or straight combining.
  • Less shattering for higher yields.

Faster crop ripening and maturing

  • Start harvesting sooner in the fall.
  • Better chance of missing bad harvest weather.
  • Finish harvest sooner.
  • Possibility of saving the crop from weather damage.
  • Peace of mind.

Drydown of green second growth and green weeds

  • Faster combine speed.
  • Elimination of swathing in some crops.
  • Less wear and tear on equipment.
  • Longer harvesting days.
