A plant perfume that attracts female moths—a world-first attractant invented by the Cotton Catchment Communities CRC and its partner Ag Biotech Australia—is already reducing pesticide use by Queensland and NSW cotton growers.

Peter Gregg and his colleagues have developed a ‘moth magnet’ that attracts Helicoverpa, the cotton boll worm moth which causes billions of dollars of damage to agriculture world-wide.

Feeding weeds fertiliser sounds like exactly the wrong thing, if you want to get rid of them, but Jennifer Firn of CSIRO Sustainable Ecosystems has been doing just that—to control African lovegrass, an invasive species of rangelands in every Australian state.

Her method works by making the weed tastier to grazing animals. It illustrates that we need to be smarter in dealing with weeds, not just reaching for the Round Up, Jennifer says. Her work was published in the Journal of Applied Ecology earlier this year and is being presented for the first time in public through Fresh Science, a communication boot camp for early career scientists held at the Melbourne Museum last week. She was one of 16 winners from across Australia.

Waste is a waste: Pigs reduce the burden on the oceans

A biotechnologist from the South Australian Research and Development Institute has taken using “everything but the pig’s squeal” to new lengths. Through clever recycling of pig waste, Andrew Ward has been able to produce feed for aquaculture, water for irrigation, and methane for energy. His ‘waste food chain’ can be applied to breweries, wineries and any system producing organic waste. Read the full article →
