Weed control thresholds: a useful concept in natural ecosystems? Weed management in natural ecosystems is often a very labour-intensive undertaking and the costs of weed control per unit area can escalate rapidly with increases in weed density Control efforts are arguably most cost-effective during the earliest stages of weed invasion; management effort should be focused here, given that particular weeds are considered sufficiently serious to warrant
Weed management strategy - NSW Environment and Heritage It outlines basic activities, such as monitoring, adaptive management and research, that support effective weed control The Strategy covers a 10-year period and is reviewed as required
Weed control - TreeProject Weeds can reduce a plants early growth rates by up to 70% compared to weed free sites and can decrease survival from an expected 90% of trees planted to as little as 10% survival rate
No. 7 – Weed Contr Weed Control Strategy Completely removing difficult to control or highly competitive weeds prior to tree planting, provide:
Biological control of weeds - CSIRO Weed biocontrol utilises a weed’s specialist natural enemies, like insects and fungi, to reduce the weed’s impact Termed biocontrol agents, these natural enemies reduce weed biomass, reproduction and or population density
Threshold Concepts: The Key to Effective Weed Control In conclusion, threshold concepts are a crucial component of effective weed control By understanding damage and action thresholds, farmers and land managers can develop proactive and targeted weed management strategies that minimize environmental impact while maintaining crop yields and quality
