Co-Author: Cara McCreary, and Jocelyn Smith, University of Guelph Ridgetown Campus The Canadian Corn Refuge Hybrid Selector is a web-based tool that has been developed through collaboration of the Canadian Corn Pest Coalition, the Ontario Corn Committee, and the Canadian Seed Trade Association to provide all the information needed to follow up-to-date insect resistance management (IRM) […]
Co-Authored by: Albert Tenuta In the past several weeks increased attention has been given to the potential for ear moulds in the 2011 corn crop and the mycotoxins potentially associated with these moulds. These mycotoxins, particularly the vomitoxin (DON) can be disruptive when fed to livestock, especially hogs. To increase our understanding of the situation […]
There are many benefits to liquid manure applications made after forage harvest. Ideally you want an applicator that uniformly applies the liquid manure. The video below shows a liquid tank applicator with a unique toolbar having a series of coulters that go into the ground at a depth of about 1 inch or 2.5 cm. […]
With increased transportation costs and the slow US economy and their decling dollar, exporting hay to the US is becoming more challenging. There is a great deal of competition in this marketplace and pressure on prices. However, we have a great product! Exporters are looking closely at increasing market opportunities to improve profitability. By developing […]
We in the weed science business are pretty good at telling producer’s to manage perennial weeds in the fall because they are controlled much better. Although its nice to believe without question, quantitative proof is always better. I recently came across a University of Guelph research report from 1977 (I was still in diapers) that […]
Co-Authors: Dr. Peter Sikkema, Dr. Clarence Swanton & Dr. François Tardif (University of Guelph) Field studies at Elora and Woodstock have evaluated soybean herbicide treatments based on their weed control efficacy and the yield protection they provided. Important differences were found among those treatments (Table 1). Table 1. Average visual control of broadleaf and grassy […]
Challenging planting conditions could affect crop emergence and early development. Additionally, a significant portion of the corn and soybean acreage was planted with limited opportunity for pre-emergence herbicide application. These factors will increase the importance of early crop scouting and staging to assess stands establishment and determine proper timing of post-emergence herbicide application. Stand Establishment […]
The handling of manure is a cost associated with the livestock portion of the farm. Handling manure has many costs connected with it, including equipment purchase and maintenance, the opportunity cost of the time it takes to apply manure to fields, and the liability if something goes wrong and there is a spill. Additional costs […]
There is lots of talk about crop residue removal for bio-energy purposes. We have gone through the first wave of trying to make it very clear to those less familiar with agriculture that this crop residue has real value. Crop Residue Value Components Crop residue value hinges on a few components: Crop residues are critical […]
Some corn fields may be at risk of extended WBC feeding this fall, particularly those that were late planted or are situated where egg laying occurred over a wider window. This year in particular, we are seeing a wide range of larval sizes because of the extended egg laying period that took place across much […]
It’s time to get out and scout for WBC damage in dry beans. Based on trap counts we are now confident that some counties experienced peak flight the last week of July and others the first week of August. Though I will admit that some trap sites are still catching lots of moths, especially the […]
It has been a few years for some since they have had to worry about soybean aphids, let alone make a spray decision. So I want to cover off the key points you need to know through some of the repeat questions that have been coming in. Anyone with more questions after reading this, please […]
I am getting a lot of emails with photos from keen reps who think they have found Brown Marmorated Stink Bugs (BMSB). I think it is awesome that everyone is taking this pest seriously and keeping an eye out for it in the fields but they are quickly learning that there are many other stink […]
The 2011 season is clearly not like 2010. We are not seeing a province wide WBC peak flight like last year. Based on the trap counts that came in this week, it appears that some counties experienced peak moth flight last week (August 1st to 7th) while other counties are still going strong and may […]
Not surprisingly, smaller weeds are easier to control. The assumption when using a glyphosate based herbicide is that when weeds get bigger, no worries, just add more glyphosate. A recent research trial conducted by Dr. Peter Sikkema (Ridgetown Campus, University of Guelph) would suggest otherwise. Take a look at the photo below. Glyphosate tolerant corn […]
