The 2013 field season was another one that presented its challenges for the Plant Sciences Weed Control Research field crew with a late start due to cold temperatures and snow in early May followed by 125 mm of rainfall from June 9 to 23.  Some trials were damaged and unable to proceed due to excess water but we were able to collect data for most of the trials.  78 trials were initiated that included a total of 1042 treatments.  We are pleased to present this report on the trials that we conducted this summer.  We are especially grateful to our field crew for the excellent work that they did in gathering the data in a very wet and trying year.  We are also very thankful for the financial support provided by the organizations listed below.  Without that support, we would not be able to maintain our program.

The 2011 field season was a very busy one for the Plant Sciences Weed Control Research field crew with one of our largest programs we have had.  We had excellent moisture in the soil at the start of the year, a little too much at a couple of our sites, and good rainfall throughout the growing season and a timely harvest.  Some trials were damaged by excess water at the Choiceland site but we were still able to obtain useful data.  87 trials were initiated that included a total of 949 treatments.  Our trials came through relatively unscathed and so we are pleased to present this report on the trials that we conducted this summer.  We are especially grateful to our field crew for the excellent work that they did.  We are also very thankful for the financial support provided by the organizations listed below.  Without that support, we would not be able to maintain our program.  With the retirement of Rick Holm in January of 2011 we are pleased to have Chris Willenborg on our team as the new faculty in the Department of Plant Sciences responsible for the weed control research program.

One of us (Rick) will retire at the end of January, 2011 having spent 27 years at the U of S and a total of 35 years working in Saskatchewan. From a personal perspective, it has been a great 35 years and I feel very privileged to have been involved in the “war on weeds” for all of that time.  Through these years I have been very fortunate to have had the opportunity to collaborate with a large number of wonderful people and for that I am most grateful.  I especially want to thank those that have worked directly with me in the program and who deserve much of the credit for any successes we’ve had – Ellis Clayton, Gerry Stuber, Clark Brenzil, Aaron Miller, Teri Ife and Ken Sapsford.  Simply put, the program couldn’t have operated without their excellent work.  I also want to sincerely thank the many organizations that have and continue to provide the financial support that keeps the wheels turning.  Without that support, there would be no field research program.  I’m very pleased that the College of Agriculture & Bioresources has decided to re-fill my position with a weed scientist and that there should be someone in place to take over the program before the next field season.  I trust that he/she will receive the same excellent support that has been provided to the program up to this point.

All the best for continued progress in the “war on weeds”.

Rick Holm, P.Ag.

The 2010 field season was a very challenging one for the Plant Sciences Weed Control Research field crew as it was for other researchers and most of the producers in the province.  The season was marked by record rainfall and lower than normal temperatures.  Frequent rains and waterlogged soils often prevented timely seeding, herbicide application, treatment assessments and harvesting.  Some trials were badly damaged by standing water / saturated soil and produced no or very limited data.  In spite of these obstacles, 88 trials were initiated that included a total of 921 treatments.  Approximately 15% of these trials were abandoned or severely compromised by the un-cooperative weather.  Amongst those plots abandoned due to water damage and restricted access due to wet soil were the demonstration plots established for the annual Crop Diagnostic Schools which, unfortunately, had to be canceled. In spite of the inclement weather, many of our trials came through relatively unscathed and so we are pleased to present this report on the trials that we conducted this summer.  We are especially grateful to our field crew for the excellent work that they did under very difficult circumstances.  We are also very thankful for the financial support provided by the organizations listed below.  Without that support, we would not be able to maintain our program.

The 2009 field season was very busy and productive for the Plant Sciences Weed Control Research field crew.  The first half of the growing season was cool and very dry with the first significant rainfall not arriving until June 21.  This resulted in slow, uneven germination of broadleaved weeds and also the small seeded crops.  Wild oat numbers were adequate despite the dry conditions.  Once the rains arrived in late June, moisture conditions were good for the rest of the growing season but the late rains triggered a second flush of weeds that made later weed control assessments more difficult.  Temperatures remained below normal throughout July and August (mean temperature in August was 6.3 degrees below the long-term normal)so crop maturity was delayed.  Warmer conditions in September brought most crops (except chickpeas) to maturity and significant harvest progress was made.  October was cool and damp and so harvest was essentially stalled for the month and was not completed until November 5.  The delayed harvest and wet weather also prevented the application of any fall herbicide treatments.

The 2008 field season was very busy and productive for the Plant Sciences Weed Control Research field crew.  The first half of the growing season was cool and very dry with the first significant rainfall not arriving until near the end of June.  This resulted in slow, uneven germination of broadleaved weeds and also the small seeded crops.  Wild oat numbers were very high despite the dry conditions.  Once the rains arrived in late June, moisture conditions were good for the rest of the growing season (141% of normal in July) and temperatures were favourable so crop yields were quite good.  However, late flushing weeds and a second stage of crop emergence made the task of evaluating weed control and crop tolerance more challenging than normal.  Harvest weather was favourable (57% of normal precipitation in September) and harvest was completed on September 30. All the planned fall treatments to begin our 2009 season were applied.

The 2007 field season was very busy and productive for the Plant Sciences Weed Control Research field crew.  Growing conditions were quite variable throughout the year.  June and August were cooler and much wetter than normal while July was much hotter and drier than normal.  One hundred and fourteen mm of rain fell in June, most of that coming in the last half of the month.  Due to the good growing conditions early in the season, germination and establishment of both the crops and weeds were good.  This allowed us to collect quality data on all of our trials.  We were able to harvest all of the trials and apply the planned fall treatments to begin our 2008 season.

The 2006 field season was once again a busy one for the Department of Plant Sciences Weed Control Research Program.  We had a very wet and rainy May and June with some flooding of a few trials in late June.  July and August were predominantly dry with a couple of timely thunder showers.  This helped to create an early harvest on many of the trials.  Due to the cool May and June the C4 weeds did not establish in the large numbers we have been used to.  However there were enough weeds, as always, that we were able to get good data from the trials.  We have had excessive amounts of rain through September and October but we were able to establish some trials with fall treatments.  We are looking forward to another exciting year with excellent conditions going into this coming spring.

The 2005 field season was very busy for the Crop Development Centre Weed Control Research Program.  May was drier than normal but growing conditions were generally good throughout the year with above average rainfall (166% above normal over the growing season).  Seventy-five mm of rain fell on June 29th and caused some temporary flooding of some experiments but there were very few adverse effects on the trials that were flooded.  Due to the good growing conditions, germination and establishment of both crop and weeds was good.  This allowed us to collect good quality data on all of our trials.  Temperature was slightly below normal once again this year so harvest of many trials was delayed and was not completed until the end of October.  However we were able to harvest all of the trials and apply some fall treatments to begin our 2006 season.
