The control of Cladosporium fulvum on greenhouse tomatoes
1994
Dubitzky, E.
Leaf mold, caused by the fungus Fulvia fulva (Cladisporium fulvum), infects tomatoes in tropical climates and in greenhouses. With the rapid growth in area of greenhouse grown tomatoes, an increase in the disease incidence in Israel was observed. This paper presents results of attempts to reduce the damage by the leaf mold to tomatoes by use of environmentally friendly materials - detergents ("Zohar LQ 215", "Nat 35"), Virol oil, and a combination of "Zohar LQ 215" and Virol oil - compared to commercial fungicides. An experiment testing the effectiveness of the various materials was carried out on over two-meter high fruit bearing tomato plants of variety no. 144 in a greenhouse in moshav Netiv-Ha'asara in the fall of 1993. The fungal spots were noticed up to a height of 1.5 meters. The treatments were carried out through four weekly applications of 10 liters of spray by a knap-sack air-blast sprayer. The treatment efficacy was analyzed using four parameters: (1) rate of mold leaf coverage; (2) general appearance of the plants; (3) height above ground to which infection reached, and (4) extent of disease suppression. The results obtained indicated that detergents and oil, separately and in combination, were as effective as commercial fungicides. In an additional trial infestation level was low and eventually stopped, leading to inconclusive results.
