AMHERST, Mass. - Eleven Massachusetts strawberry farmers have been recognized by a state program that promotes environmentally friendly farming practices. The program, known as Partners with Nature, is a certification program for growers who practice integrated pest management (IPM), a system of farming which reduces pesticide use by making crops less inviting to pests, by encouraging natural predators and parasites, and by carefully monitoring pest populations so that crops are sprayed only when pests are present in damaging numbers. "IPM has allowed strawberry growers to reduce their use of pesticides by about 30 percent," says William Coli, UMass Extension IPM coordinator.
