Weeds
Manage weeds in the orchard (part 2)
Weeds compete with trees for moisture and nutrients and can also create a favourable micro-climate for pests and disease. Chemical herbicides have been the mainstay of weed management in orchards since the mid 1940s.
Manage weeds in the orchard
Why manage weeds?: Rapid canopy establishment and early cropping are keys to profitability in any orchard, particularly modern capital-intensive systems.Weeds compete with trees for moisture and nutrients and can also create a favourable micro-climate for pests and disease.
Grochem launches Beloukha, a new organic herbicide
Leading supplier, Grochem Australia, has launched a new non-selective, organic herbicide in a major breakthrough for the horticulture sector. Beloukha herbicide gives growers and their advisers a naturally derived option for effectively managing broadleaf and grass weeds around orchards, vineyards, nurseries and a host of other situations.
Wetout® — a superior, new generation non-ionic surfactant
After extensive research, SST has developed a new generation non-ionic surfactant that may soon become the new standard across Australia and New Zealand Wetout® is a unique proprietary formulation of vegetable based surfactants that improves efficacy in every aspect while reducing unwanted negatives such as spray drift.
Return to residual herbicides to control weeds
Graeme Hardwick, AgNova Technologies’ area manager for South Australia, Sunraysia and Western Australia, is seeing tree crop growers switching back to residual herbicides to save time and money and avoid problems with resistance to glyphosate.

Long term weed control is back
It’s back to the future in orchard weed control this season as growers return to residual herbicides to control weeds.
Herbicide use, trunk cankers & tree damage
Glyphosate is one of the most highly used herbicides in the world because it is economical, easy to use, broad-spectrum, and kills quickly.
Residual herbicides save time
Many growers struggle to complete jobs in time. Weather conditions also delay many jobs. So what can help this situation?
Pre-emergent/residual herbicides
Pre-emergent herbicides are a useful tool for combating weeds. They are generally applied before the spring break—before the new weeds germinate.
Smarter herbicide programs
Repeat applications of glyphosate or paraquat in orchards have allowed tolerant species to escape and multiply. It is now the perfect time to re-introduce a residual herbicide into your integrated weed control program.
Handling glyphosate–resistance
Annual ryegrass resistance to glyphosate herbicide has been documented in four NSW orchards and one in SA.
