Diversity Effects

A field study at three highland sites near Quito, Ecuador, was conducted to determine whether host-diversity effects on potato late blight would be as important as recently found in studies conducted in temperate areas. We compared three potato mixtures and use of mixtures in combination with different planting densities and two fungicide regimes. Treatment comparisons were made by absolute and relative measures of host-diversity effects and incorporating a truncated area under the disease progress curve as a means of standardizing comparisons across sites. Potato-faba intercrops consisting of only 10% potato provided an estimate of the effects of dilution of susceptible host tissue. Host-diversity effects were very different across study sites, with a large host-diversity effect for reduced disease only at the site most distant from commercial potato production. Planting density had little influence on host-diversity effects or on late blight in single-genotype stands. Fungicide use in combination with potato mixtures enhanced a host-diversity effect for reduced late blight. Potato-faba intercrops produced only a small decrease in potato late blight. Effects of host diversity on yield were variable, with the greatest increase in yield for mixtures treated with fungicides at the site most distant from commercial potato production. The effects of host diversity on late blight severity may be less consistent in the tropical highlands than in the temperate zone, but can contribute to integrated disease management.

Methods Of Control

An inexpensive, simple, chemical control of wireworms in land to be used for vegetable production has long been sought in the Prairie Provinces. Existing methods of control (3, 4, 5, 6) are not wholly satisfactory for row crops. The cultural measures commonly advocated (6) will reduce wireworm infestations sufficiently that cereal crops can be grown without serious damage, but they are not usually sufficiently effective that potatoes or other row crops can be produced successfully. Crude naphthalene is the most satisfactory of the chemical methods recommended (3, 4, 5) but it is too costly for material, is difficult to handle and apply, and is effective only under certain conditions of soil, moisture and temperature. As a result, commercial potato production on the prairies has been restricted largely to districts and fields where wireworms are virtually absent.

Potatoes are an important crop in the United States, and Florida is ranked the 7th producer nationwide for potato production. In Florida, potatoes are mainly planted on sandy soils with low nutrient- and water-holding capacities. Nitrogen is the most limiting nutrient in these soils. Adopting efficient fertilization methods such as fertigation is imperative for minimizing leaching and improving use efficiency of nitrogen. This new 12-page article provides step-by-step guidelines for fertigation practices for commercial potato production.

Potato tuber necrotic ringspot disease (PTNRD), caused by potato Y potyvirus isolate NTN (PVYNTN) of the N virus strain group, was first described in Hungary in 1980. It has spread throughout Europe, with the most recent reports from Portugal and Italy in 1997 to 1998 (1). Superficial necrotic ringspot areas on tubers, typical of PTNRD, were first observed in commercial potato fields of the Nevrokopi region in northern Greece in 1994. Affected cultivars included Timate and, to a lesser extent Spunta, the original seed of which came from the Netherlands. PVY was identified from all tubers tested by indexing on Nicotiana tabacum and subsequent testing of the plants by double antibody sandwich-enzyme-linked immunosorbent assay (DAS-ELISA). The potato seed lots were rejected by the local authorities. PTNRD reappeared in the same area in 1998 in a more aggressive manner. Cultivar Hermes, imported from Scotland, was most affected, with very severe symptoms in 80% of the tubers. Symptoms appeared in early September, 40 days after defoliation of the plants. Other cultivars were affected at lower rates; cv. Spunta showed typical symptoms and cvs. Fabola, Santana, and Irvila exhibited atypical cracks and blisters. In all cases, PVY was isolated in N. tabacum and its presence confirmed by DAS-ELISA. Immunocapture-reverse transcription-polymerase chain reaction with specific PVYNTN primers (2) detected the characteristic 835-bp product in all cultivars tested. The incidence of PTNRD seems to be expanding in northern Greece, where it has become a threat to potato production. PTNRD symptoms were also observed in southern Greece (Ahaia) in experimental “crossing” fields of seed stocks. In this case, the disease seems to have spread especially in cv. Marfona.

AbstractPotato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infection by the tuber necrotic strain of Potato virus Y (PVYNTN). PTNRD negatively impacts tuber quality and marketability and poses a serious threat to seed and commercial potato production worldwide. PVYNTN symptoms differ in the cultivars Waneta and Pike: Waneta expresses severe PTNRD and foliar mosaic with vein and leaf necrosis, whereas Pike does not express PTNRD and mosaic is the only foliar symptom. To map loci that influence tuber and foliar symptoms, 236 F1 progeny of a cross between Waneta and Pike were inoculated with PVYNTN isolate NY090029 and genotyped using 12,808 Potato SNPs. Foliar symptom type and severity were monitored for 10 weeks, while tubers were evaluated for PTNRD expression at harvest and again after 60 days in storage. Pairwise correlation analyses indicate a strong association between PTNRD and vein necrosis (τ = 0.4195). QTL analyses revealed major-effect QTLs on chromosomes 4 and 5 for mosaic, 4 for PTNRD, and 5 for foliar-necrosis symptoms. Locating QTLs associated with PVY-related symptoms provides a foundation for breeders to develop markers that can be used to screen out potato clones with undesirable phenotypes, e.g., those likely to develop PTNRD or to be symptomless carriers of PVY.
