“…LGR was found to be an important component of field resistance (Colon et al 1995). Such an association between components of infection also appears to exist in other tuber bearing Solanum species as the components of field resistance studied here concerned 16 accessions from S. andigena (12), S. stenotomum (3), S. juzepczukii (1) and three cultivars bred from interspecific crosses.…”

“…The components of field resistance to Phytophthora infestans vary in association with each other, whereby infection frequency shows the least association with the other components ( Van der Zaag 1959;Umaerus 1970;Umaerus and Lihnell 1976;Birhman and Singh 1995). Lesion growth rate was found to be a very important component of resistance (Colon et al 1995).…”

“…Colon et al (1995) tested 22 cultivars, released between 1900 and 1954 in The Netherlands and known to be free of R-genes, for their level of quantitative resistance in the field to a complex race of P. infestans. The quantitative resistance, measured through the AUDPC, correlated closely to the resistance ratings reported in the yearly Dutch Recommended Cultivar Lists from 1929 to 1954.…”

This experiment was carried out to investigate whether and how much field resistance to late blight, caused by Phytophthora infestans, is present in the local cultivated potato germplasm. In total 36 entries were compared in a field experiment in an area highly conducive to late blight development. Of the 36 cultivars 32 were local cultivars belonging to five Solanum species, S. tuberosum (1 accession), S. andigena (18), S. juzepczukii (2), S. stenotomum (9) and S. ajanhuiri (2). The other four cultivars were derived from breeding programmes, one being the Dutch cultivar Alpha used as a highly susceptible control. The 36 cultivars were planted according to a simple 6 · 6 lattice design with three replicates. Each replicate was divided in six incomplete blocks each with six cultivars. The disease severity was assessed weekly during 9 weeks starting 48 days after planting. The area under the disease progress curve (AUDPC) was used as a measure of the field resistance. Nine isolates from surrounding potato fields were tested for their virulence to the resistance genes R1-R11 using 22 differential cultivars. The components of the field resistance of 19 of these cultivars were compared in the greenhouse using a local isolate with virulence to all known R-genes, except to R9. The nine isolates represented seven races with a race complexity varying from 7 to 10 virulence factors. All isolates carried virulence against R1, R2, R3, R7, R10 and R11, while virulence against R9 was absent. The AUDPC among the 32 local cultivars ranged from very large, significantly larger than that of 'Alpha' to very small. The AUDPC from S. stenotomum accessions ranged from very large to intermediate, those from S. andigena accessions from large to very small. Especially among the S. andigena accessions interesting levels of field resistance were found. Four components of field resistance were assessed, latency period (LP), lesion size (LS), lesion growth rate (LGR) and relative sporulation area (RSA). All four showed a considerable variation among the cultivars. The LP ranged from 3½ to 6 days. The LS ranged from 225 mm 2 to 20 mm 2 . The LGR varied about six-fold, the RSA more than 10-fold. The components tended to vary in association with one another. LP and LGR were well associated with each other and had a significant correlation with the AUDPC.

“…Although, metalaxyl containing fungicides reveals good results against P. infestans (Gisi and Cohen, 1996) continuous applications of these fungicides has resulted in resistance development in P. infestans (Clayton and Shattock, 1995;Colon et al, 1995;Delen, 2016) and a considerable proportion of metalaxyl-insensitive genotypes of P. infestans has been documented from different regions worldwide. In 1980, phenylamide resistant isolates of P. infestans were detected on field-grown potatoes in Ireland, Netherlands and Switzerland and the detection of these resistant isolates were associated with a decline in the disease control (Jmour and Hamada, 2006).…”

Potato (Solanum tuberosum L.) has been remained an important agricultural crop in resolving global food issues through decades. The crop has experienced enormous growth in terms of production throughout the world in recent decades because of improvement in agricultural mechanization, fertilizers application and irrigation practices. Nevertheless, a significant proportion of this valuable crop is still vulnerable to losses due to prevalence of different viral, bacterial, fungal and nematodes infestations. Late blight, caused by Phytophthora infestans (Mont.) de Bary, is one of the most threatening pathogenic diseases which not only results in direct crop losses but also cause farmers to embrace huge monetary expenses for disease control and preventive measures. The disease is well known for notorious 'Irish Famine' which resulted in drop of Irish population by more than 20% as result of hunger and potato starvation. Globally, annual losses of crop and money spend on fungicides for late blight control exceeds one trillion US dollars. This paper reviews the significance of late blight of potato and controlling strategies adopted for minimizing yield losses incurred by this disease by the use of synthetic fungicides. Advantages and disadvantages of fungicides application are discussed.
