“…persicae induce a condition in nectarine which is almost indistinguishable from that described in reports of "peach tree short life" (PTSL) in the United States caused by P.s. syringae (Ritchie & Clayton 1981). PTSL syndrome involves an interaction between infection with P.s.…”

New plant disease record in New Zealand:Pseudomonas syringaepv.persicaefrom nectarine, peach, and Japanese plum

A pathovar of Pseudomonas syringae van Hall 1902 has been isolated from Prunus spp. (nectarine, peach, and Japanese plum) in New Zealand. This pathogen causes a decline syndrome, resulting in tip die-back and in necrosis of fruiting arms, main branches, trunk, and roots of trees. It also attacks leaves and fruit. The pathogen can be distinguished in laboratory tests from other stone fruit pathovars of P. syringae by several cultural characters. In symptoms and host range, the pathogen is similar to Pseudomonas syringae pv. persicae (Prunier et al. 1970) Young et al. 1978 and can be considered as a localised counterpart of that pathovar. This organism was proved pathogenic to nectarine and peach, is a weak pathogen of Japanese and European plum and is not pathogenic to apricot and cherry. More severe disease development occurred in plants inoculated in autumn than in winter. Conditions which appear to be associated with serious orchard losses have been examined.

“…PTSL syndrome involves an interaction between infection with P.s. syringae and cold injury, particularly with the early breaking of dormancy in spring followed by frost (Ritchie & Clayton 1981). The onset, intensity, and duration of tree dormancy vary from season to season, and place to place.…”

“…Bacterial canker has been used commonly for the disease caused by P. syringae syringae in cherry (Cameron 1962) and peach (Dowler & Peterson 1966;English et al 1980), but is also given to the disease caused by P. syringae morsprunorum (Wormald 1931) Young et al 1978, a pathogen similar to P. syringae syringae that occurs in other countries on European plum (L.) (Wormald 1931) and cherry (Crosse 1957). The symptoms of canker described (Wormald 1931) for P. syringae morsprunorum in European plum are identical to those of apoplexy in apricot (Klement et al 1974) and PTSL in peach (Ritchie & Clayton 1981).…”

“…Overseas, two widespread disorders, 'apoplexy' of apricot as described by Klement et al (1974), and peach tree short life (PTSL) (Yadava & Doud 1980;Ritchie & Clayton 1981) have caused serious widespread losses. Both conditions are characterised by wilting of limbs or entire trees after the necrotic girdling of limbs or trunk.…”

“…Both conditions are characterised by wilting of limbs or entire trees after the necrotic girdling of limbs or trunk. Although other factors may be connected with these two complex disease syndromes, one of the principal agents is P. syringae syringae (Klement et al 1974;Ritchie & Clayton 1981). The disease in apricot occurring in New Zealand resembles apoplexy, and although P. syringae persicae is associated with damage to peach and nectarine in New Zealand, the syndrome in these species corresponds to PTSL.…”

Orchard management and bacterial diseases of stone fruit

The major bacterial pathogens of stone fruit in New Zealand are Xanthomonas campestris pv. pruni (Smith 1903) Dye 1978, causing bacterial spot of stone fruit, Pseudomonas syringae pv. syringae van Hall 1902, causing bacterial blast of apricot and cherry, and P. syringae pv. persicae (Prunier et al. 1970) Young et al. 1978, causing bacterial decline of nectarine and peach. Management practices can have an important influence on the incidence of these diseases in stone fruit. This review examines treatment in the nursery, susceptibility of cultivars, effect of root health on susceptibility, rootstocks and grafting, pruning, irrigation management, frost control, and spray measures. Where appropriate, recommendations to reduce disease incidence are made.
