Soybeans are incredibly adaptive and can yield well when planted late. Although early May planting is ideal weather in August and September often has more influence on final yield than early planting. When planting is delayed, fewer days are required to reach maturity because of the plants ability to adjust to the season. A one month delay in planting results…
Tracey Baute April 28, 2017 4060 Comments Off on Conditions are Ideal for Wireworm and Grub AssessmentsSoil temperatures are at 10 degrees C which means that wireworms and grubs are active near the soil surface. So it is also a great time to set up wireworm baits or dig for grubs. For the 2017 planting season, growers wanting to purchase and plant neonic treated corn and soybean seed require a pest assessment report (PAR) through an…
Horst Bohner March 28, 2017 8139 Comments Off on Phosphorus and Potassium Management for Corn, Soybeans, and WheatCrop yields have increased significantly since fertility recommendations were developed in Ontario. Crop nutrient uptake and grain nutrient removal have increased proportionately. A study was initiated in 2011 with funding from the Grain Farmers of Ontario to evaluate a corn-soybean-wheat rotation on four sites with relatively low soil test P and K levels. Areas within each test site were built…

OMAFRA Field Crop Team September 14, 2016 2845 Comments Off on Integrated Pest Management Course for Corn and Soybeans – free until April 30, 2017Integrated Pest Management (IPM) training is free until Apr 30, 2017 Ontario is helping corn and soybean farmers comply with recent rules protecting insect pollinators by continuing to provide mandatory training for free until April 30, 2017. Farmers need the training if they wish to purchase and use neonicotinoid-treated corn and/or soybean seeds. The half-day course is available in English or…
Meghan Moran August 5, 2016 7735 Comments Off on Two-Spotted Spider Mites in Edible Beans and SoybeansThe dry season is leaving the edible bean and soybean crops susceptible to two-spotted spider mites, especially now that wheat harvest is wrapping up. In some years, spider mites will also feed on corn leaves. Spider mite damage and management are very similar for soybeans and edible beans. Because of the dry conditions and likely earlier harvest of edible beans…
OMAFRA Field Crop Team April 26, 2016 1646 Comments Off on Integrated Pest Management (IPM) Course for Corn and SoybeansOnline and In-Class course offered for FREE until August 31, 2016. Starting on August 31, 2016, successful completion of the Integrated Pest Management (IPM) Course for Corn and Soybeans will be required in order to purchase or plant neonicotinoid-treated corn and soybean seed. Following successful completion of the course, farmers will receive a certificate number. Farmers will need to…
The number of acres of soybean planted in Ontario has been as high as 3 million in recent years, because of strong prices and development of high yielding varieties suited for Ontario’s different growing regions. In comparison, we have relatively few acres of dry edible beans (around 130,000 ac total) even though dry beans have a high profit potential. So why don’t…
Cashcropper allows you to compare the net profitability and fertility requirements for different crop rotations within a given field. This app is powered by over 30 years of data on crop yield responses to different rotations from trials conducted by the University of Guelph. The app uses default yield values provided by crop insurance records in Ontario and uses the…
Much of the province received welcome showers over the weekend. A few areas were hit with heavy rains that caused flooding in low lying areas. In most cases water drained away quickly but standing water could still be found in some fields two days after the rain. See picture #1. Flooded soybeans on June 1st, 2015 at Ridgetown, ON. How…
Horst Bohner February 20, 2015 4992 Comments Off on Evaluating Soybean Fungicide Timing and TankmixesOver the last 10 years there has been increased interest in applying foliar fungicides to soybeans in Ontario. Liquid in-furrow fungicide application is also now being used in more US states on soybeans. Many trials have been conducted in Ontario to assess the yield and seed quality benefits of foliar fungicides. Very little work has been conducted to evaluate in-furrow…
Various areas in the province received frost in September and there continues to be concern the impact subsequent frost will have on the soybean crop. The extent of injury will depend on the stage of development as well as the length of exposure to frost. MECHANISM Low temperatures injure plants primarily by inducing ice formation between or within cells. The…
Compiled by Chris Brown, edited by Horst Bohner 2012 Soybeans were originally introduced to Ontario as a forage crop for cattle. Today, the vast majority go for crush and the IP market. Letting the crop mature and harvesting the seed is far more profitable than using it as a forage crop but in some cases forage soybeans may be an…
In Ontario there are many root/stem diseases which cause wilting symptoms in soybeans. With the hot, dry conditions this year over much of the province some of these diseases such as stem canker, Fusarium wilt, charcoal rot have taken advantaged of the additional stress. Fusarium wilt or blight of soybeans can affect soybeans at any stage of development and is…
