Advance planning required with soybeans in crop rotation

MISSISSAUGA, ON, OCTOBER 31, 2012 – Analysts predict 1M acres of soybeans will be planted in Manitoba next year. With seed purchase timing well underway, growers with soybeans in their rotation should first consider their system history to avoid volunteer weeds, advises BASF Canada Inc. (BASF).

“Choosing seed from the same system year over year can increase the risk of volunteer weed populations, particularly when rotating canola to soybeans,” says Harley House, Brand Manager, Clearfield® Crops.

While the majority of canola volunteers will appear the year after a rotation, canola can volunteer for up to four years. Using a system such as the Clearfield Production System for canola before introducing or adding more acres of soybeans into the rotation is an effective way to manage the risk.

“With the Clearfield Production System for canola, you’ll get control of Roundup Ready® and Liberty Link® volunteers with herbicides like Ares®,” he says. “Ares provides new modes of action and is effective for flushing control of volunteer canola up to several weeks after application. It can help manage volunteers in a rotation with soybeans.”

In a recent survey, 97 per cent of Clearfield canola growers indicated they were satisfied or very satisfied with the overall performance of Ares on multiple weeds, including volunteer types. Additionally, 97 per cent said they would recommend Ares to other canola growers.

“It’s not just about seed anymore,” says House. “It’s equally important to consider which systems will be used over the course of your crop rotations and some extra planning ahead to help get your next crop off to the best possible start.”
