A range of options is needed for effective summer weed control.. All these summer weeds have populations that are either resistant to glyphosate or naturally tolerant of glyphosate (such as feathertop Rhodes grass).. The weeds in question - awnless barnyard grass, feathertop Rhodes grass (FTR), windmill grass, liverseed grass, sowthistle and the notorious fleabane - are all a problem in summer fallows: "And all have populations either resistant to glyphosate or naturally tolerant to glyphosate (such as FTR)...

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...

Time is right to fight flaxleaf fleabane.. "When treated young, at one month or less, susceptible flaxleaf fleabane plants in fallow can be controlled with glyphosate quite often a glyphosate mixture or double knock is required for optimal control," Dr Widderick said... For rosette control in fallows Dr Widderick said the most consistently effective treatments were double-knocks (sequential application), particularly with glyphosate and Tordon 75-D followed seven days later with Spray...

Dr Michael Widderick, principal research scientist at the Queensland Department of Agriculture, Fisheries and Forestry (DAFF), says research is being conducted to equip growers with options before they find themselves in a situation where glyphosate is no longer useful... "Northern growers have relied on no-till systems for the past few decades, but taking tillage out of the system means that growers are heavily reliant on herbicides for weed control," he says... Dr Widderick says the industry is now having to think outside the square and consider approaches to the herbicide-resistance issue that are new to the northern region - such as harvest weed-seed control options including the Harrington Seed Destructor, chaff carts and windrow burning...
