Presentation Transcript

  1. Knockdown Herbicide Resistance

  2. Increase in glyphosate resistance in 7 years Heap, 2018

  3. # stopped counting; * Multiple Resistance BCDMZ

  4. Glyphosate resistance mechanisms Wild radish – multiple resistance to B, I, F, M

  5. Paraquat resistance

  6. Glufosinate – Group N

  7. Amitrole - Group Q

  8. Preventing resistance to knockdown herbicides • Use tank mixes of two different modes of action at robust rates that are effective on the target species – remember synergy is rare – keep both rates high! • Prevent any survivors of spraying from setting seed. • Use a double knock – 2 effective herbicide applications or non-herbicide tactics in close succession – 1 to 14 days apart • monitor spray effectiveness • Rotate modes of action See WEEDsmart “Big 6” for cropping
