“…Effect of Foliar Applications of Fungicides on the Phylloplane Mycoflora 61 several specific systemic compounds and others which are effective against some groups of pathogens are likely to have almost no effect on saprophytes. In earlier studies benomyl has been reported to be non-persistent on leaf surfaces as compared with non-systemic fungicides (BENNETT 1971, WARREN 1974, CARTER and PRICE 1975, SWINBURNE et al 1975, and MEHAN and CHAUHAN 1981. Species of fungi such as Alternaria, Dreehslera (FOKKEMA et al 1975) and Phoma (WARREN 1974) are insensitive to benomyl derivative.…”

Colletotrichum gloeosporioides and Pestalotia psidii were found to be the dominant pathogens causing leaf spots and fruit diseases of guava. Effects of two fungicides in rainy (wet) and four fungicides in the winter (dry and cool) seasons separately, in concentrations of 500, 1500 and 3000 mg a.i. I−1 (ppm) have been investigated on the pathogens and on composite phylloplane fungi. Benomyl was found most effective against the population of pathogens and checked disease development. However, it was effective only at the schedule of three successive foliar applications. The application of captan did not check P. psidii as effectively as benomyl but it had a marked adverse effect on many of the phylloplane fungi. A signif, icant decrease in the number of fungal species colonizing mancozeb and dichlone‐treated leaves was observed. Lesion measurement and spore germination tests against both pathogens following chemical treatments in vivo and in vitro respectively have also been made.

“…That B. subtilis was found to be as effective as PMN in conjunction with dithianon suggests such biological control with carbendazim might replace PMN, presumably to the benefit of the environment. Carbendazim was, however, shown to reduce the number of bacteria in leaf scars (Swinburne, Flack & Brown, 1975) and consequently the compatibility with B. subtilis requires testing. Normally two applications of PMN are made in autumn: one at the commencement of leaf fall and the other at 50% leaf fall (Moore & Bennett, 1960).…”

S U M M A R YIn a factorialized field trial cells of B a d u s subtilis or phenylmercuric nitrate (PMN) were applied as sprays in autumn to manually defoliated apple trees, cv. Bramley's Seedling, artificially infected with Nectria galligena. Trees were additionally sprayed with dithianon at intervals in May and June or left unsprayed at this time. B. subtilis in conjunction with dithianon, and PMN with dithianon were equally effective in the control of canker over a 2-yr period. Dithianon alone gave some control, as did PMN but B. subtiZis was not effective without additional applications of dithianon.
