Drones have been taking to Wheatbelt skies in a bid to improve surveillance and control of a key agricultural pest plant, skeleton weed.
Summer weeds can rob subsequent crops of soil nitrogen and stored soil water. They can also reduce crop emergence by causing physical and/or chemical interfence at seeding time.
In an integrated weed management program, control of weeds should occur in the fallow, pre-sowing, early post-emergent and in pasture phases.
Some aquatic plants used in ponds and aquariums are highly invasive and have become serious weeds in natural waterways.
Introducing new plants to an area can have positive and negative effects on the environment, economy and community.

High priority invasive species are defined in the Invasive Species Plan for Western Australia as high risk species that can establish widely, and if so cause the most undesirable impact.
In-crop weed competition causes losses costing around $1 billion per annum for Western Australia.
Preventing weed seed set provides an opportunity to control weed seed set in the pasture, late fallow, late stubble and in-crop phases.
This management strategy provides an opportunity to control weed seed set in the pasture and during harvest.
