Root-knot nematodes cause losses to Australian agriculture that are estimated at more than $100m per annum. Vegetables are some of the most susceptible crops and soil fumigants and nematicides such as methyl bromide and fenamiphos are widely used, particularly on crops such as tomatoes, potatoes, carrots, and cucurbits. Since these chemical control strategies are coming under close scrutiny from health authorities and environmental control agencies, there is an urgent need to develop alternative nematode control practices. The project aimed to test new biological control products for nematodes that had been jointly developed by Queensland Department of Primary Industries and Crop Care Australasia Ltd. This research has produced encouraging results, as activity against root-knot nematodes was achieved at application rates far lower than has been achieved elsewhere with other biological products.
