With organic food growers reporting double-digit growth in U.S. sales each year, producers are challenging a proposed California pest-management program they say enshrines a pesticide-heavy approach for decades to come, including compulsory spraying of organic crops at the state's discretion. The California Department of Food and Agriculture's pest-management plan says compulsory state pesticide spraying of organic crops would do no economic harm to organic producers, on the grounds that the growers could sell sprayed crops as non-organic instead. I would rather stop farming than have to be a conventional farmer. I think I am not alone in that," said Zea Sonnabend, a Watsonville organic apple-grower with California Certified Organic Farmers. The fate of the pest-management plan outlined by the state isn't a theoretical concern. It's an immediate issue ... due, in part, to a disease-carrying pest. The disease spread by the Asian citrus psyllid kills citrus trees. California's $2.4 billion citrus industry has found incursions by the bug. The standard treatment for the citrus pest is conventional pesticides, including neocotinoids linked to the decline of crop-pollinating bees. Organic farmers are asking the state to give more consideration to non-toxic controls, including long-term methods to strengthen crops and habitats in advance against marauding tropical species, said Kelly Damewood, policy director for California Certified Organic Farmers.
