“…Fungicide treatments are generally the most effective control measures, but are not economically feasible in all areas of the world and may not be effective under weather conditions favorable for epidemics (Herriot et al 1986). Resistant cultivars are potentially the most economical control measure because they can extend the intervals between fungicide sprays while maintaining control of the disease (Madden et al 1978;Shtienberg et al 1995;Keinath et al 1996).…”

Alternaria solani causes diseases on foliage (early blight), basal stems of seedlings (collar rot), stems of adult plants (stem lesions), and fruits (fruit rot) of tomato. Early blight is the most destructive of these diseases and hence receives considerable attention in breeding. For over 60 years, breeding for early blight resistance has been practiced, but the development of cultivars with high levels of resistance has been hampered by the lack of sources of strong resistance in the cultivated tomato and by the quantitative expression and polygenic inheritance of the resistance. In some accessions of wild species, high levels of early blight resistance have been found, but breeding lines still have unfavorable horticultural traits from the donor parent. Recently, the first linkage maps with loci controlling early blight resistance have been developed based on interspecific crosses. These maps may facilitate markerassisted selection. This overview presents the current knowledge about the A. solani-tomato complex with respect to its biology, genetics, and breeding.

“…However, resistant accessions have been identified within related wild species of tomato, in particular the green fruited species L. hirsutum and the red fruited species L. pimpinellifoloum. A number of control measures were suggested by different researchers for minimizing the disease losses but the use of resistant cultivars remained the most reliable and economical one [5]. Nonjudicial use of fungicides adds human and environmental hazards.…”

One laboratory study was carried out at the Department of Plant Science and Biotechnology, University of Nigeria, Nsukka to test the efficacy of these three fungicides; Antracol, Benlate and Captan in the control of Alternaria solani with a view of recommending the potent ones to farmers for use in the control of disease caused by Alternaria species. Cultures of A. solani isolated from diseased tomato plants were used for the study. Effects of the fungicides on radial growth and sporulation were investigated. The cultured plates were set up in a completely randomized design in four replicates. Radial growth measurements were determined by taking the diameter of the colony in each cultured plate along two equatorial axes of the plate and their average recorded for all four replicates of a given concentration to the nearest millimeter. Antracol, Benlate and Captan inhibited radial growth, sporulation and germination of A. solani. Captain was the most effective of the fungicides in inhibiting radial growth causing 46.80, 63.29, 68.94 and 73.75 percent inhibition at 10, 100, 200 and 500 ppm respectively. These inhibitions were significantly greater (p= 0.05) than those of Benlate and Antracol at the same levels followed by Benlate while Antracol was the least. Therefore, the percent intibition in vitro clearly showed that among three fungicides tested, Captan was the most effective and has the best potential of being employed in the control of A. solani in the field or in the green house.
