We know, kochia sucks!<\/span><\/strong><\/h2>\n

It\u2019s easily becoming one of the most troublesome weeds in Western Canada, and the available herbicide options to control it are decreasing. Kochia populations are becoming resistant to multiple herbicide groups (including Group 2-, 4-, and 9-). What\u2019s even scarier is that about 45 percent of the population has stacked resistance to all three herbicide groups.<\/p>\n\"\"\n

Kochia is one heck of a weed. There are a number of characteristics that make kochia quick to adapt and tough to manage for farmers.<\/p>\n

    \n
  • A single plant can produce up to 25,000 seeds \u2013 <\/strong>In addition to producing a ton of seed, kochia also cross-pollinates. So a plant can be pollinated by one with different genetics in it, and pass along herbicide resistance.<\/li>\n
  • Efficient seed spreader \u2013<\/strong> Kochia is a tumbleweed so its seeds are distributed as plants tumble through fields. According to Saskatchewan Pulse Growers the germination rate of kochia seeds can be up to 60 \u2013 70 percent when temperatures reach 25\u00b0C.<\/li>\n
  • Short seedbank longevity \u2013<\/strong> This makes it better for kochia populations to develop herbicide resistance because a plant sets all its seed in one year. If that plant had resistance all that seed will germinate next year and there will be minimal susceptible kochia left. This means kochia populations can shift from susceptible to resistant very quickly.<\/li>\n<\/ul>\n
