Western Australian grain growers are being urged to be mindful that early sowing under wet, warm conditions can impact the length of efficacy of pre-emergent herbicides.
Water quality is often overlooked as a possible contributor to herbicide failure and can lead to confusion over the herbicide resistance status of weeds on a property.
Some of Australia’s most well-known farm chemical lines will be brought under the one banner when the sales teams from Nufarm Australia and Crop Care merge from August 1, 2017.
Nufarm Limited has reported underlying earnings before interest, tax, depreciation and amortisation of $128.7 million, underlying earnings before interest and tax of $85.0 million and net profit after tax of $20.0 million for the six months to January 31, 2017.
The European Chemical Agency’s (ECHA) Committee for Risk Assessment (RAC) has concluded that available scientific evidence has shown that glyphosate – the widely-used herbicide in Australian agriculture – should not be classified as a carcinogen, as a mutagen or as toxic for reproduction.
An increasing number of no-till farmers are reverting to an occasional, strategic tillage as the most cost-effective way of controlling hard-to-kill weeds in an era when herbicide resistance is on the rise.
Nozzle type is an important consideration when growers are weighing up spray drift risks, but there are other critical factors, according to an internationally renowned expert in the field.
Western Australian growers need to target herbicide and other control tactics to the correct weed species in both cropped and remnant areas this summer to benefit 2017 crops.
Spray drift incidents have flared in the summer cropping zone of eastern Australia as a late storm season triggers weed growth, prompting farmers to ramp up herbicide applications.
Ultra-narrow row configurations are showing promise as a technique for outcompeting with weeds.
