The root-knot nematode (RKN) Meloidogyne luci is included in the Alert List of European Plant Protection Organization, because it has potential negative impacts on economically important crops. Identification plant species/cultivars resistant to M. for its management. Susceptibility 35 commercial species/cultivars, from nine families a isolate Portugal was evaluated pot assays, assessing root g...

Yams (Dioscorea spp.) are food crops of growing significance in sub Saharan Africa. Unfortunately, nematodes are major pests to their production. A study was undertaken in major yam growing areas of Uganda to investigate the association of plant parasitic nematodes with damage symptoms. Nematodes were assessed from tubers, roots and surrounding soil for seven cultivars belonging to Dioscorea al...

Alternaria brown spot is a serious disease of fruit and foliage of citrus. This disease caused by Alternaria alternata and causes serious economical losses on susceptible cultivars in Iran. In this research, susceptibility of seven citrus cultivars including Fortune, Orlando tangelo, Mineola tangelo, Page, Clementine, Sour orange and Sweet orange (Thomson) fruits to A. alternata was investigate...

Olive leaf spot (OLS) or peacock spot, caused by the fungal pathogen Spilocaea oleagina, can cause reduced growth and yield in olive trees (Olea eurapaea). Investigations were carried out during December 1999 and January 2000 to measure the prevalence and severity of olive leaf spot in the Auckland, Waiheke Island, Wairarapa, Marlborough and Canterbury growing regions of New Zealand. The suscep...

the susceptibility to terbacil of six randomly selected strawberry cultivars (‘aromas’, ‘chambly’, ‘harmonie’, ‘kent’, ‘la clé des champs’ and ‘seascape’) was analysed using chlorophyll florescence (cf) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. terbacil was applied at one of five rates...

One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...
