A good thick mulch helped to control weeds and reduce herbicide costs at Cedar Meadow Farm. The consistent use of a cover crop was also necessary. Total pesticide use on tomatoes decreased from $200/A to $75/A. This was attributed to a reduction in the use of fungicides for control of early blight and insecticides for control of Colorado Potato Beetles. Consistent with the work of Dr. Aref Abdul-Baki (USDA), Dr. Ron Morse (VA Tech) and others, the onset of early blight was delayed by the use of no-till tomatoes. The Penn State weather station (FAST system), situated near Cedar Meadow Farm, allowed forecasting of conditions favorable for early blight susceptibility. A delay of 3-7 weeks to spray a protective fungicide was possible in the past, although this year's constant moisture didn't make much difference. The farm has experienced years of varied weather conditions -wet, dry, and near normal. Every year, early blight has been delayed and healthier plants have been observed up to the end of the growing season. A cumulative total of over 200 acres of no-till tomatoes have been planted over an 11 year period without spraying to control Colorado Potato Beetles! No Admire insecticide was used at transplanting. Herbicide use for corn and beans has also dropped from $25/A to$18/A. Total pesticide usage on the whole farm has decreased 30%. Beneficial insects have increased
