A near-perfect growing season has produced a high-quality crop of canning peaches in the Goulburn Valley this year.

But sadly for growers, the Australian dollar and cheaper imported products have forced the local cannery to cut its intake of fruit again.

That means thousands of tonnes of peaches are likely to rot on the ground.

Invergordon orchardist Doug Brown says it has been the growing season from heaven, but he is now going through the hellish task of knocking 50 tonnes of perfectly good fruit off his trees.

"I'll run through with a tractor and mulch and break it all up and rot it back into the ground," he said.

"I can't think of any market I can target, so the best thing I can do is get it off the tree for the tree's sake."

It is a similar story at Peter Hall's orchard at Mooroopna. He expects to have about 100 tonnes left over.

"It's very disappointing to see a crop that you have spent money on just go to waste," he said.

For several years now SPC Ardmona has been forced to cut the amount of fruit it takes from orchardists.

"It's a combination of a very high Australian dollar," Mr Hall said.

"I think our country has weak anti-dumping laws that aren't policed that well and there's been a rise in the amount of imported fruit that sits on the shelves."

The Shepparton cannery is certainly feeling the pinch.

Last week its parent company announced a $146 million writedown in value of SPC Ardmona.

Orchardists say politicians could help by showing more interest in Australia's food processing industries.

"They can support the industry just like they have manufacturing and the car industry and hopefully they will get the growers through the tougher times they are experiencing at the moment," Mr Hall said.
