“…Kibris, Poncirus trifoliata cvs Yerli, Jacobson, SEAB, Luisi, Rubidoux, Benecke, Rich, Ferme Blanche, citrange cv. Troyer and C. ampullaceae (Tuzcu et al, 1984). Goksedef (1980) found a direct relationship between the quantity of pectic substances in bark tissues and resistance of rootstocks to P. citrophthora, and concluded that the rootstock containing the highest amount of pectic substances was the most resistant.…”

In the last 20 years, seven different Phytophthora species (P. cambivora, P. hibernalis, P. citrophthora, P. capsici, P. cactorum, P. drechsleri and P. infestans) have been determined in Turkey on chestnut, citrus, pepper, strawberry, melon, and potato respectively. Two of them, P. citrophthora and P. capsici, which attack citrus and pepper, are very destructive and have the greatest economic importance. P. citrophthora has caused approximately 15% fruit losses every year and 8–30% infection on a susceptible lemon cultivar in Cukurova region. P. capsici is very dangerous for pepper‐spice and pepper‐paste production because it causes up to 100% drying and killing of pepper plants under conditions of poor drainage and incorrect irrigation practices. P. cambiuora, which causes the ink disease of chestnut, has spread from the Black Sea coast to the Mediterranean; about 20 000 chestnut trees have been killed by this organism from 1952 to 1970. Recently, P. infestans on potato is achieving importance, as the potato area increases. The other species of Phytophthora do not have any economic importance and only first records have been noted.

Gummosis, caused by several Phytophthora species, is one of the most serious constraints to citrus production in Corsica. The current Phytophthora population on citrus trees is mainly composed of P. citrophthora divided into two major groups, namely G1 and G2, with two additional minor groups. Following changes in cultural practices, favourable climatic conditions, and introduction of new hosts, repeated gummosis outbreaks have been observed. The pathogenicity of several Phytophthora isolates of each group collected in citrus groves was assessed for gummosis disease on 20 citrus scion and rootstock cultivars. All isolates tested proved virulent on citrus but extensive pathogenicity differences were observed among and within Phytophthora groups. The data indicate that G1 isolates of P. citrophthora are pathogenic to resistant rootstocks such as Poncirus trifoliata or Carrizo citrange, and moderately aggressive towards scions. In contrast, isolates of the group G2 tend to display a greater aggressiveness to a number of scion cultivars, but are not virulent to P. trifoliata and its hybrids. Implications of these data on disease management are discussed.U. S.
