Abstract
The effects of the fungicide maneb and the insecticide carbaryl on the microflora of lettuce leaves were studied in field plots in 1983 and 1984. In 1983, populations of filamentous fungi were significantly, but temporarily, reduced by a single application of maneb. This treatment did not reduce populations in 1984; however, two additional applications of maneb did result in a significant decline in fungal populations when compared with unsprayed plants. Maneb had no effect on bacterial populations in either year. Carbaryl altered neither bacterial nor fungal populations. Pesticide applications did not change the composition of the microflora. Phoma and Fusarium spp. were the fungi most frequently isolated from lettuce leaves.
