WEED-IT Optical Spot Spraying technology is an extremely effective resistant weed management tool.

Herbicide resistance is an ever increasing challenge in cropping systems around the world. The number of resistant weed species in Australia is second only to the United States.

Over recent times, the management of herbicide resistance globally has been increasingly focused on reducing the weed seed bank and maintaining low
seed bank levels.

"The unifying framework … is mitigation of viable weed seeds into the soil seed bank and maintaining low weed seed banks to minimise population proliferation, evolution of resistance to additional herbicidal sites of action, and spread."

WEED-IT Optical Spot Spraying technology is an extremely effective resistant weed management tool and allows growers to:

» Implement a “go early” approach by cost effectively spraying weeds when they are young and fresh rather than waiting for an “expected” second germination. Usually by the time of the second germination, many weeds have become large, stressed and have often set seed
» Economically use extremely robust rates of chemicals that give increased weed control when compared to usual blanket applications
» Mix up their chemistry – WEED-IT allows growers to change to different — and often more expensive — products and still be economical. Mixing and rotating herbicides is key to combatting resistance

WEED-IT Agronomic Approach

Many consultants and growers are now aiming for a “go early and go hard” approach with their WEED-IT systems with several operators modifying their fallow spraying program to a more calendarbased system rather than focusing on weed numbers and germination events. Small, young weeds are easier to control and have not set seed – not only allowing for easier control but also driving the weed seed bank down over several passes.
