“…Isolates belonging to the fourth clade have already been observed in Korea. The mode of pathogenic action of the isolates often collected in Korea is different from the mode of those belonging to the fourth clade (Han et al, 2003a; Koh et al, 2012; Vanneste et al, 2011a). The fourth clade showed significantly lower pathogenicity on Hayward than on the other cultivars, including Hort16A (Balestra et al, 2009).…”

“…actinidiae on kiwifruit ( Actinidia spp. ), is one of the major diseases that occasionally causes severe damage in orchards and extensive economic losses in Japan (Serizawa et al, 1989; Takikawa et al, 1989), Korea (Ko et al, 2002; Koh, 1995; Koh et al, 1994, 2012), Italy (Balestra et al, 2009; Scortichini, 1994), and many other countries (Balestra et al, 2010, 2011; Bastas and Karakaya, 2012; Everett et al, 2011; Vanneste et al, 2011b). In Korea, bacterial canker on kiwifruit was first observed at Jeju in 1988, and has rapidly spread since (Koh et al, 1994; Lee et al, 2005).…”

We developed a model, termed D-PSA-K, to estimate the accumulated potential damage on kiwifruit canes caused by bacterial canker during the growing and overwintering seasons. The model consisted of three parts including estimation of the amount of necrotic lesion in a non-frozen environment, the rate of necrosis increase in a freezing environment during the overwintering season, and the amount of necrotic lesion on kiwifruit canes caused by bacterial canker during the overwintering and growing seasons. We evaluated the model’s accuracy by comparing the observed maximum disease incidence on kiwifruit canes against the damage estimated using weather and disease data collected at Wando during 1994–1997 and at Seogwipo during 2014–2015. For the Hayward cultivar, D-PSA-K estimated the accumulated damage as approximately nine times the observed maximum disease incidence. For the Hort16A cultivar, the accumulated damage estimated by D-PSA-K was high when the observed disease incidence was high. D-PSA-K could assist kiwifruit growers in selecting optimal sites for kiwifruit cultivation and establishing improved production plans by predicting the loss in kiwifruit production due to bacterial canker, using past weather or future climate change data.

“…In fact, the first canker occurrence on the yellow-fleshed kiwifruit cultivar Hort16A by Psa2 was observed in 2006 at a kiwifruit orchard in Pyoseon-myeon, Seogwipo-si, Jeju Island (Koh et al, 2010). Psa3 was first detected in 2011 on the yellow-fleshed kiwifruit cultivar Yellow-king and red-fleshed kiwifruit cultivar Hongyang at an orchard in Dodeok-myeon, Goheung-gun, Jeonnam Province (Koh et al, 2012). Since then, frequent Psa3 incidences have occurred on many yellow- and red-fleshed kiwifruits in major kiwifruit growing areas in Korea.…”

A bacterial pathogen, Pseudomonas syringae pv. actinidiae (Psa), is a causal agent of kiwifruit bacterial canker worldwide. Psa biovar 3 (Psa3) was first detected in 2011 at an orchard in Dodeok-myeon, Goheunggun, Jeonnam Province in Korea. In this study, we present the results of an epidemiological study regarding Psa3 occurrence on kiwifruit orchards in Korea for the period of 2013 to 2015. Since the first detection of Psa3 in 2011, there was no further case reported by 2013. However, Psa3 was rapidly spreading to 33 orchards in 2014; except for three orchards in Sacheonsi, Gyeongnam Province, most cases were reported in Jeju Island. Entering 2015, bacterial canker by Psa3 became a pandemic in Korea, spreading to 72 orchards in Jeju Island, Jeonnam, and Gyeongnam Provinces. Our epidemiological study indicated that the first Psa3 incidence in 2011 might result from an introduction of Psa3 through imported seedlings from China in 2006. Apart from this, it was estimated that most Psa3 outbreaks from 2014 to 2015 were caused by pollens imported from New Zealand and China for artificial pollination. Most kiwifruit cultivars growing in Korea were infected with Psa3; yellow-fleshed cultivars (Yellow-king, Hort16A, Enza-gold, Zecy-gold, and Haegeum), red-fleshed cultivars (Hongyang and Enza-Red), green-fleshed cultivars (Hayward and Daeheung), and even a kiwiberry (Skinny-green). However, susceptibility to canker differed among cultivars; yellow- and red-fleshed cultivars showed much more severe symptoms compared to the green-fleshed cultivars of kiwifruit and a kiwiberry.

We estimated the averaged maximum incidences of bacterial canker at suitable sites for kiwifruit cultivation in 2020s and 2050s using D-PSA-K model with RCP4.5 and RCP8.5 climate change scenarios. Though there was a little difference between the estimation using RCP4.5 and that using RCP8.5, the estimated maximum disease incidences were more than 75% at all the suitable sites in Korea except for some southern coastal areas and Jeju island under the assumption that there are a plenty of infections to cause the symptoms. We also analyzed the intermediate and final outputs of D-PSA-K model to find out the trends on the change in disease incidence affected by climate change. Whereas increase of damage to kiwifruit canes in a non-frozen environment caused by bacterial canker was estimated at almost all the suitable sites in both the climate change scenarios, rate of necrosis increase caused by the bacterial canker pathogen in a frozen environment during the last overwintering season was predicted to be reduced at almost all the suitable sites in both the climate change scenarios. Directions of change in estimated maximum incidence varied with sites and scenarios. Whereas the maximum disease incidence at 3.14% of suitable sites for kiwifruit cultivation in 2020s under RCP4.5 scenario was estimated to increase by 10% or more in 2050s, the maximum disease incidence at 25.41% of the suitable sites under RCP8.5 scenario was estimated so.
