However, the seed or extract would have to be available and applied at the appropriate time. Neem extracts are apparently not being considered for investigation for plague locust control in Australia. Advanced trials are to begin shortly. The author has observed, in Cairns, North Queensland, that the Micracerotemes turneri species of termite died if a few mLs of concentrated ethanolic neem extract was placed into its nests . Australian primary producers may have the opportunity of using neem cake, instead of neem extract, for controlling such nematode species on lighter soils.
Neem cake is processed from the material remaining after the crushing of the neem seed.
Fertilisers mixed with neem cake have been applied to soil, prior to the planting of rice in India and other Asian countries for effective nematode control. The future of public-funded neem research in Australia is unclear. The Queensland Department of Primary Industries has carried out trial plantings and investigations on the neem tree and related research but the future of Australian research in neem is not clear. However, the costs of registering pesticides can often prevent small businesses from gaining registration for neem products in Australia. Both products have been registered, since 1993, throughout the US for 'all food and feed products'.
