The peak vegetable growers group, Ausveg, wants the Federal Government to help find alternatives to the growing list of banned chemicals.
Ausveg has drawn up a list of eight pesticides that are banned or facing suspension, including the fruit fly control fenthion.
The Authority is currently reviewing fenthion, and could suspend its use by the end of this month.
Simon Coburn, of Ausveg, says Australian growers need help from the government.
"We are a very small player in the world game," he said.
"What we're trying to do is make it appealing for companies with the global resources behind them to invest in that.
"What we need to do is work with government to find ways that will attract those international, multinational companies to invest in the industry."
A northern NSW stonefruit grower says he'll leave the industry if the nation's chemical regulator withdraws fenthion, which is used on crops including stonefruit, citrus and tomatoes.
Bangalow peach and nectarine grower Ray Hick says it's looking likely that he'll have to bulldoze his orchard.
"There's no way that I'll go through a season sending fruit away that I'm sure is whole. The last thing I want is to be frightened every night when the phone rings for fear someone's on the phone saying I've got a maggot in the fruit," he said.
"There's nothing that we know of that, if I sell all of my fruit, that not one or several pieces will contain live maggots in it."
Mr Hick says growers need more time to find an alternative.
"The industry is spending in excess of half a million dollars endeavouring to look for alternatives and looking at lower dosage rates and longer withholding periods and what we have asked the APVMA, and we've asked the politicians, to try to understand that we need a little bit more time," he said.
"We've employed outside scientists to do this research and we really need time for them to be able to give us the results of their tests.
"Growers are not chemical companies, we're not chemists, we can't develop a chemical product.
"And if we're going to look at releasing sterile flies and baiting, it will take probably five years to do a small area, and at this stage I can't see the Federal or State Government giving us hundreds of millions of dollars to rid the fruit fly.
"So their request is very very difficult."
The APVMA's pesticides program manager, Dr Raj Bhula, says that as regulator, it has the responsibility to ensure that agricultural chemicals can continue to be used safely and that the findings of the report are a trigger to take action to ensure that consumers remain protected.
The Authority published a report that found that a two to six-year-old child eating certain fruits and vegetables treated with the chemical may be exposed to residues higher than the public health standard.
