Edible bean growers could get more weed control options

Ridgetown College research shows that older chemistries can help control glyphosate-resistant weeds in strip till

By
When the Weed Society of America challenged its members to evaluate weed pressure on field crops, Peter Sikkema found that in Ontario edible beans were most challenged by weed pressure. “The crop I work on that is most affected by weed interference is dry beans,” the professor at University of Guelph’s Ridgetown campus said at […] Read more
Over 30 years, the active ingredient volume of herbicide applied on crops has declined in Ontario, mostly because glyphosate 
is applied at lower rates than the herbicides it replaces.

Glyphosate drives long-term herbicide changes

Ontario keeps track of detailed herbicide use every five years, which shows how the use of active ingredient has declined

By
A study of glyphosate use in Ontario shows the herbicide has created significant change in crop management. It shows that while corn and soybean acreage and yield have increased in the province since 1983, the impact of herbicide use per acre has declined, in large part because glyphosate has displaced other herbicide chemistries. Why it […] Read more

Cover crops can be tricky to kill

Cover crops can be important tools to improve soils, but there’s no single control solution

By
Cover crops can do a lot for the soil, but keeping them from becoming covering weeds requires the right herbicides applied at the right rate — to kill them at the right time. What cover crop is used, too, should be appropriate for the job the farmer wants to accomplish. Why it matters: Cover crops […] Read more

Taking the dicamba cleanse

Experts remind growers to take an active approach to sprayer cleaning, and of the importance of ammonia in removing dicamba residues

By
The sensitivity of soybeans and other plants to dicamba — a volatile auxin-based herbicide employed in various forms since the 1960s — is extreme. Even trace amounts can cause significant damage to susceptible crops, meaning proper equipment cleaning is critical to avoiding unintended problems. Why it matters: Use of the herbicide will increase with the […] Read more

FMC deal for DuPont assets wins clearances

By
The chemical company set to take up a significant chunk of DuPont’s crop protection work in Canada has picked up the last of the regulatory clearances it needs to close the deal. Philadelphia-based FMC Corp. announced Thursday it received the final approval needed, from the Competition Commission of India, to close the deal the company […] Read more

Herbicide supplier Albaugh said to be exploring sale

By
Reuters — Albaugh LLC is exploring a sale that could value the privately held U.S. producer of agricultural crop protection chemicals at more than US$1.5 billion, including debt, according to people familiar with the matter. Albaugh, controlled by its 67-year-old founder Dennis Albaugh, is working with investment bank JPMorgan Chase and Co. to discuss a […] Read more

Syngenta, DuPont patent new herbicide chemistry class

By
The crop chemical arms of DuPont and Syngenta are working together on a new class of herbicide chemistry they’ve jointly patented and taken to the “pre-development” stage. DuPont Crop Protection and Syngenta announced Monday they’ve published a joint patent, titled “Substituted cyclic amides and their use as herbicides,” and expect to launch herbicides based on […] Read more
