Pigs Join Apple Orchardists In Fight Against One Of Fruit's Most Destructive Pests - NYT

[hatrack]

CLAYTON TOWNSHIP, Mich. (AP) -- Jim Koan has gone hog-wild in his battle against a beetle that threatens his 120-acre organic apple orchard. As part of a research experiment believed to be among the first of its kind, Koan is using pigs to help protect his fruit from the plum curculio, a tiny insect that is among the most destructive apple pests.

More than two dozen porkers patrol his orchard, gobbling down fallen, immature apples containing the beetle's larvae. After a successful trial run late last spring, he and some researchers at Michigan State University are preparing for year two of the experiment at AlMar Orchards and Cidery in eastern Michigan.

They hope their work will someday help fruit growers throughout the world reduce the use of pesticides while diversifying their agricultural operations, as he is doing. He plans to periodically sell off the offspring of his four original hogs, keeping only those he needs. ''I'm not ready to say that everybody should run out and do this but I'll tell you, after the first year, I'm a whole lot more optimistic and excited by the possibilities,'' said Dave Epstein, a tree fruit pest-management specialist at the university and the project's lead researcher.

The quarter-inch-long plum curculio is particularly difficult for growers like Koan to control because no good organic controls have been developed for them. The beetle can be controlled conventionally, often with the pesticide azinphos-methyl. But the U.S. Environmental Protection Agency is phasing out the powerful pesticide, marketed under the trade name Guthion, because of the risks it poses to farm workers and to the environment. Adult female curculios cut crescent-shaped flaps in the skin of newly formed apples and lay their eggs inside, where they hatch. The beetle larvae burrow into the center of the young fruit, making it drop prematurely in late June or early July. After spending about two weeks inside, the larvae migrate from the fallen fruit into the soil, where they pupate for 10 to 12 days before emerging as adults to attack the remaining fruit and start the cycle all over again.

1. I thought EVERYBODY already knew that letting livestock

such as sheep or pigs clean up your fruit "drops" was good for orchard health. They act like this is news.

I think Gene Logsdon discussed this in some of his early books, like Homesteading. It's an example of why diversified small-scale organic farming is more desirable in the grand scheme of things than factory-style agribusiness production.

2. plus the bonus of free fertilizer :-) nt

5. and keeping the ground aerated, pigs do a good job of plowing
