Co-written by Joanna Follings, Cereal Specialist Should you use 2,4-D to emerged wheat in the fall to control weeds? The short answer is no. First, the label clearly states under the “Application Timing” section: “Do not apply to seedling winter cereals in the fall.” Second, there are other labelled and less injurious herbicide options that provide […]
Authors: Meghan Moran and Mike Cowbrough Harvest aid treatments in dry edible beans will provide a more even dry down of the crop and any escaped weeds, making harvest more efficient. Controlling escaped weeds can also reduce seed stain, improving bean quality. There are six products registered for pre-harvest use in edible beans in Ontario, […]
Conditions: Warm, sunny and dry conditions over the last 2 weeks were ideal for field work. Timely rains May 10-12 brought 20 mm (5 to 50 mm) of welcome precipitation across eastern Ontario. With most of the cereals, new forage seedings, corn and part of the soybean acreage seeded/planted between April 27th and May 10th, […]
A beautiful stand of red clover can provide as much as 75 kg of nitrogen per hectare (when at 40 cm tall) for next years corn crop. However, if the clover crop is not “killed off” in the fall, then preparing a suitable seedbed to plant next years crop in is often significantly delayed resulting […]
Below are examples of corn and soybean injury demonstrated at the FarmSmart field expo, July 12, Elora Research Station (University of Guelph) Scenario 1: Just this past spring, I had contact with a producer who had accidentally applied Guardian Plus (glyphosate + chlorimuron + flumioxazin) post emergent to his glyphosate tolerant soybeans. This mistake is […]
Below is an overview of herbicide injury scenarios presented at the SouthWest Crop Diagnostic Days . Scenario 1: A field of corn has been replanted due to a poor stand. After planting the producer has decided to remove the existing stand as it is effectively a weed to the new crop. Unfortunately weather delayed the graminicide […]
The majority of growers, crop consultants and researchers will tell you that it is always better to manage dandelions in the fall then in the spring. Fall management simply is more effective. The photo below clearly illustrates this point. The outside rounds of this field were managed last fall and there is an obvious difference […]
Here is a summary of herbicide injury scenarios in soybeans (glyphosate tolerant), white beans, kidney beans and adzuki beans showcased at the South West Crop Diagnostic Days in Ridgetown on July 6th and 7th, 2011. Scenario 1: Sandea (halosulfuron) is currently not registered in Ontario. Above is a post-emergent application of the 70 g ai/ha […]
Above average precipitation in the spring of 2011 has illustrated for many, areas within their fields that are slower to drain and even prone to have standing water (see below). Certain herbicides are at greater risk of causing crop injury in areas where there is standing water. The reasons are two fold. First, the plants […]
