Citrus growers in eastern Australia can now export to Japan with greater market flexibility thanks to the development of cold storage regimes effective against fruit fly. The new method kills Queensland Fruit Fly in citrus stored for 14-16 days at temperatures of 2° or 3°C, reducing damage and improving fruit quality.
Researchers have identified 20 major European carp breeding hot spots in Australia's Murray Darling Basin, which could be targeted for control measures to reduce carp numbers in regional waterways. The study found that heavy rain and floods enable the carp to disperse their larvae, supporting the larval drift theory.
Research by NSW DPI has identified the Whitefringed weevil larvae as the culprit behind small holes in leaky irrigation pipes. The larvae can chew through plastic piping using their dark brown pincers, leading to significant yield loss and water waste for lucerne growers.
A new molecular tool, eco-tilling, helps detect early signs of herbicide resistance in weeds, reducing the need for chemical use. This technique uses reverse genetics to identify mutations at a fraction of the cost of alternative methods.
A study found that mature forest produces almost 10 times as much sugar per hectare than recently logged forest, but overall honey yields are still high due to extensive flowering. Nectar production in young trees regrowing after logging is not significantly affected, contradicting beekeepers' concerns.
Australian White Dorper breeders are utilizing a newly developed DNA test to identify and manage the genetic disorder dermatosparaxis, which causes extreme skin fragility. The disease has been reported in other breeds and can result in death or euthanasia if left unchecked.
Research by Dr James Chin and colleagues reveals that antibiotics not only kill bad bacteria but also maintain a pool of resistant genes within microbial communities. This means that subsequent therapy with another antibiotic may be ineffective due to increased resistance.
Researchers have developed a 3D computer model to analyze the cranial mechanics and bite force of the Great White Shark. The study used high-resolution simulations to estimate the maximum forces that Great Whites can exert, with implications for protecting submarine cables and communication systems.
Researchers found high levels of phosphorus and low organic carbon in vegetable growing soils, leading to reduced crop yields. Compost made from recycled garden offcuts can help improve soil quality and reduce the need for synthetic fertilizers.
Researchers have developed protocols to maximize post-release survival of commonly caught species, including luderick and Murray cod. Key recommendations include cutting lines on fish that swallow hooks, resulting in improved mortality rates for some species.
Trials at NSW DPI's Wollongbar Agricultural Institute found agrichar, a black carbon byproduct of pyrolysis, triples wheat yields and doubles soybean production when applied at 10 tonnes per hectare. The technology also reduces greenhouse gas emissions by up to 99% compared to traditional farming methods.
