Sowthistle is the newest problem weed to show signs of glyphosate resistance in the north... "Individual plants within the suspect populations survived the glyphosate much better than they should have and within two or three weeks some plants were starting to regenerate again," Mr Cook said... "More work is being done to determine whether it is resistance, and if so what level, but it is a timely reminder to maintain diversity when undertaking weed control and to closely monitor weeds after sprays to detect and control survivors," Mr Cook said...

"Feathertop Rhodes grass can be a very aggressive weed once established but the longevity of seed viability is actually quite brief," he said "Feathertop Rhodes grass may again be a problem following the wet end to harvest in the north this year, as research shows us it is often one of the first weeds to establish on bare ground following rainfall events in spring and summer... Control of established populations of large feathertop Rhodes is difficult, extremely costly and generally incompatible with zero till farming, so the focus must be to to keep it out of farming paddocks wherever possible but be ready to respond to new incursions very rapidly, Mr Daniel said... "Knockdown herbicides can be an effective tool for control results are very dependent on favorable application conditions together with weed stage and size," he said...

H. marinum is widely referred to as sea barley grass around the world, and H. hystrixis known as Mediterranean barley grass... Conditions that favour germination and establishment The seed of common sowthistle can germinate at temperatures in the range 5 C to 35 C. Germination is ultimately determined by moisture availability, as a moist environment is preferred... There is a high proportion of seedling emergence from shallow seed sources, whereas more deeply buried seeds remain dormant and long-lived with a half life estimated at 10 years...

The machine was developed to eliminate weeds that germinate from weed seeds and residue placed onto tramlines using chaff deck systems.. While most weed seeds rot and become compacted by wheel traffic over time, the weed seeds that germinate have the capacity to develop resistance to multiple herbicides and herbicide groups.. Mr Knight says although the concept of burning weeds is not new, the use of shrouded burners to destroy weeds growing on tramlines in CTF systems is novel and early trial results suggest the technology has promise...
