We have all seen the footage of ducks invading rice paddies in Asia where they are used to control pests.
Most of us have used chooks to clear a piece of land, fertilise it and then plant the next crop.
Another example of using poultry is ducks in the orchard.
Jane Major, a grazier from the Yass region of NSW has been using ducks for pest control in her orchard.
"We have had pure bred Khaki Campbell ducks for 20 years, just as pets and for eggs," Jane said.
"They free range in our enclosed, fox proof orchard.
"They have been terrific in totally eliminating coddling moth from our Johnathon Apple tree.
"Before the ducks, the tree was riddled with coddling moth and about 80 per cent of the apples were affected.
"When we introduced ducks to the orchard, it took about two seasons to get rid of the codling moth.
"I assume the ducks ate the larvae when they were in the ground around the tree."
Ducks in orchards are also excellent for eating any slugs or snails and they will graze and forage around the trees.
They don't dig like chooks or scatter mulch but they will eat smaller vegetable seedlings and can be clumsy and squash smaller plants.
Another benefit is that ducks lay large eggs and they can also be used for the pot, just like any poultry.
I would love to have other readers let us know their experiences, as would Jane.
"I would like to know if other readers have had similar success with getting rid of, or at least controlling, other pests like elm beetle that have larvae in the soil as part of their life cycle," Jane said.
