• Efficacy test shows Flavocide™ controls key insect pest in cereal crops world-wide
• Control of Russian wheat aphid demonstrated in laboratory study
• Highlights potential of Flavocide™ to control another pest in major global food crops
• Cereal crop insecticide market estimated at A$980m per annum

Bio-Gene Technology Limited (ASX: BGT, “Bio-Gene” or “the Company”) is pleased to announce the positive results of a successful Flavocide™ laboratory trial against major cereal crop pest the Russian wheat aphid (RWA; Diuraphis noxia). An estimated A$980m is spent on cereal crop insecticides globally* with aphids a primary target.

The laboratory bioassay using Flavocide™, a liquid formulation containing flavesone (one of the Company’s lead compounds) was performed by cesar, an Australian based contract research organisation. It was designed as a pilot to examine the efficacy of the molecule against RWA, and to suggest future direction of research.

• RWA is native to southern Russia and South West Asia, but is now found in Europe, North America, Africa and Australia.
• This major cereal pest was found in South Australia in 2016 and infestations have since spread into Victoria, NSW and Tasmania.
• The RWA are a major pest in wheat, barley and some grasses, and can cause significant yield lossesin cereal crops, at times up to 75%.
• The RWA is distinct from other cereal aphids as it injects salivary toxins in addition to removing nutrients during feeding. "
