No lesions were observed on terminals. Leaves on the ground were a more important overwintering site than buds at all three locations. Mean number of conidia detected per leaf averaged over all three locations and 2 years was 66.7, whereas an average of only 2.8 conidia per bud were detected. Conidia from buds also had lower germination (6.5%) than conidia from leaves (38.8%). Number of conidia per leaf and conidial germination did not differ consistently among locations. Number of overwintering conidia detected per leaf did not decrease from November 1991 to May 1992, but was less in May 1993 than in November 1992. Treatment of leaves with urea in the fall had minimal effects on amount of leaf area remaining in May. Overwintering on grass or bare ground or treatment with urea did not affect the number of conidia detected per leaf or their ability to germinate.}, number={7}, journal={PLANT DISEASE}, author={FILAJDIC, N and SUTTON, TB}, year={1995}, month={Jul}, pages={695–698} }

Delicious). The effect of mite feeding on disease and yield was most apparent in 1991, when disease severity and levels of mite infestations were higher than in 1992 and 1993. Disease severity was increased with increased mite densities in more instances than it was with defoliation and fruit drop. Fruit quality characteristics such as diameter, weight, firmness, commercial color, and soluble solids content were not affected to a great extent by increased mite densities although soluble solids content was reduced in about one-half of the tests with a high intensity of Alternaria blotch.}, number={7}, journal={Plant Disease}, author={Filajdic, N. and Sutton, T.

At the high disease level, disease severity was greater in treatments in which a high aphid density was present. Defoliation was increased at one location in 1 year. Fruit quality characteristics such as soluble solids content, diameter, and weight were often decreased at the high aphid density; firmness was increased and commercial color decreased in some cases. Yield was not affected by aphids.}, number={7}, journal={Plant Disease}, author={Filajdic, N. and Sutton, T. B. and Walgenbach, J. F. and Unrath, C. R.}, year={1995}, pages={691} }

On the basis of estimates of variance and cost, the mean optimum number of leaves per terminal was 16.88 for evaluating disease severity and 19.37 for determining disease incidence. The optimum numbers of terminals per tree for assessing severity, incidence, and defoliation were 1.2, 1.18, and 2.04, respectively. The variation in disease among leaves and among terminals contributed equally to overall estimates of variance [...]}, number={7}, journal={PLANT DISEASE}, author={FILAJDIC, N and SUTTON, TB}, year={1994}, month={Jul}, pages={719–724} }
