2014 Herbicide Resistant Testing Results – University of Guelph

Apr 15, 2014

According to the University of Guelph’s testing lab for herbicide resistant weeds, 86% of all submissions sent from the 2013 season were resistant to a particular herbicide that had historically been effective. A total of 29 samples were tested with one unprecedented sample having five species (pigweed, common ragweed, lamb’s-quarters, green foxtail and giant foxtail) that were resistant to one class of herbicide (group 2, i.e. Pursuit), with one of the five species (lamb’s-quarters) being resistant to two different classes of herbicides (group 2, i.e. Pursuit and group 5, i.e. Aatrex).

Three Canada fleabane samples were submitted, unfortunately only one was able to produce seedling plants but was resistant to glyphosate, according to Dr. François Tardif who provides the testing service to Ontario farmers.

Dr. Peter Sikkema’s research group has been surveying the incidence of glyphosate resistant Canada fleabane, common and giant ragweed and an overview of those maps can be found here.

The table below provides a summary of the weed species tested, the number of confirmed herbicide resistant samples and to what herbicide group the sample was resistant to.

Video: Brent Avalanche 98-Series Dual Auger Grain Carts

The Brent® Avalanche® dual-auger grain carts have set powerful standards for unloading speed, convenience, capacity and durability. The all-new 98-Series of Avalanche grain carts carry on this tradition and give the operator more auger side reach and height along with choice of right- or left-hand unloading to meet individual preferences. The dual-auger design provides a narrow transport width and low profile for greater stability and ease of transport and features the fastest unloading speeds, no matter the moisture of grain. In addition to the industry’s first pivoting vertical unloading auger, the 98-Series is standard with a 4-way directional downspout that is operated on the tractor’s SCV remotes. The all-welded construction, rubber cushioned tongue suspension and heavy-duty dual-belt drive system ensure years of dependable service. Capacities range from 3,150 to 1,100 bushels and with unloading speeds up to 1,000 bushels per minute depending on model, operators can get back to the combine quicker to keep harvest moving smoothly. Bigger, faster, better. The Avalanche 98-Series dual-auger grain carts feature dynamic performance that now pivots to new heights.
