Kane" To: sanet-mg@amani.ces.ncsu.edu Subject: Ant Problems In Peru Relative to Lockertz's most recent and other discussions concerning organic versus sustainable agriculture, we have a problem in Peru that hits on the issue. Our project includes both cash-crop in terms of organic coffee and sustenance in terms of community gardens run by Mother's Clubs. In the coffee tree nurseries, carniverous ants are killing the earth worms in the humus beds. Because of our organic certification we can't apply any available insecticides. At the same time, ants are consuming the small plants in the Mother's Clubs gardens before they can produce anything. I'm at the point of understanding what is meant by comments to the effect that organic farming might not be sustainable. Our form of sustainability applies nature's little helpers. In other areas of IPM, we are applying fungus to counter Coffee Borer insect and leaf rust with some success. We have hints of problems relative to rust and its ability to expand a rate greater than the fungus (sustainability at what level of production?). Does anyone have any ideas on how to attack this problem organically? What is the least toxic way to handle the problem using chemicals? Thanks for your help.
