Navel orange growers have until the end of the month to decide whether to support a new commodity levy.
The levy, which the citrus growers organisation introduced in 2006, lapses next year and requires a growers vote for it to continue.
Orange and Tangelo Growers chairman David Ingoe says the levy which in the past year brought in almost $77,000 is vital to pay for research, such as into new fungicides, insecticides, rootstock and varieties.
In the past it has funded research on integrated pest management and the new Australian whitefly problem, he says.
Voting closes on 29 April.
