WEE WAA – Australian cotton farmers are dropping balls filled with tiny wasp eggs from planes to control pests to reduce the use of chemical insecticides.
New South Wales company Crop Capsules says the practice can reduce the need to spray for silverleaf whitefly by more than 90%.
“There is no silver bullet for controlling silverleaf whitefly. But by using biological control and understanding the science surrounding beneficial insect behaviour, silverleaf whitefly can be controlled when the Crop Capsules are deployed early enough,” said team manager Adam Perkins.
