As we approach spring 2021 it\u2019s important that we understand our weed challenges and how they are impacted by both spring and fall weather. While much of Ontario is under snow at the moment, warmer weather is on the horizon. Now is great time think about your herbicide plan for tackling weed challenges in 2021.<\/p>\n
Canada fleabane is a weed to watch out for in the spring. Joe Thomas, Nufarm territory manager in southwest Ontario, has some simple, straightforward advice on how and when to control fleabane in fields where you\u2019ll be planting soybeans.<\/p>\n
\u201cAn early spring means fleabane can grow past the staging window to be effectively controlled so be sure to time your burndown application right,\u201d says Joe. \u201cFor best results, products like Bifecta<\/a>\u00ae <\/sup>and BlackHawk<\/a>\u00ae<\/sup> should be applied before fleabane grows to be 10 cm across. The combination of Bifecta and BlackHawk has also shown strong control of glyphosate-resistant fleabane 28 days after application.\u201d<\/p>\n To learn more about application timing, watch Joe\u2019s short in-field demo from 2020 that includes recommendations for pre-seed and pre-emergent weed control with BlackHawk and Bifecta for fleabane and other broadleaf weeds.<\/p>\n
