“…However, as global warming leads to climate change, significant changes in the relative importance of pathogens, including soilborne pathogens, are likely to occur across southern Australia (Chakraborty et al ., ; Barbetti et al ., ; Jones & Barbetti, ). Climate changes, such as an extension of effective summer rain further southwards, particularly in eastern Australia, will lead to increased rates of breakdown of infested soilborne residues, especially as average winter rainfall is falling across southern Australia (Barbetti et al ., ). Further investigations may help to explain some of the changes in severity of disease caused by P. clandestina or the relative distributions and incidence of individual soilborne pathogens in relation to climate change.…”

Studies were carried out in controlled environment rooms reflecting field situations. In the presence of the devastating soilborne pathogen Phytophthora clandestina, subterranean clover (Trifolium subterraneum) seedling emergence was significantly affected by moisture, soil type, temperature and cultivar. The level of rotting of tap and lateral roots was significantly affected by nutrition, soil type, temperature and cultivar. There were significant interactions involving temperature, moisture, soil type and cultivar; cultivar resistance, high moisture, high or medium temperature, high nutrition and sand soil all contributed towards less pre‐emergence damping‐off and tap and lateral root disease and to greater clover productivity. Host resistance of subterranean clover cultivars was critical for reducing disease severity and increasing productivity, even when favourable environmental conditions for severe disease occurred. In the presence of P. clandestina, the most resistant cultivar, Seaton Park, performed best under a high temperature, high nutrition and high moisture combination, but showed lower productivity under conditions of low nutrition or lower temperature, even when moisture level was high. In contrast, less resistant cultivars Riverina and Meteora had less disease and greater productivity under low moisture conditions. Findings reflect field observations that pre‐emergence damping‐off and root disease from P. clandestina in subterranean clover is particularly severe under colder conditions and in nutritionally impoverished sandy soils, and demonstrate how variations in soil type, nutrition, moisture, temperature and cultivar have profound effects on the expression and severity of phytophthora pre‐emergence damping‐off and root disease and the productivity of subterranean clover forages.

“…That genotypes showing the highest levels of resistance generally display a more consistent resistance response against SR (Garg et al, 2010a,c;Barbetti et al, 2011;Ge et al, 2012) is very encouraging, as high level resistance that is expressed independently of environmental conditions and/or pathogen pathotype is likely to be more robust across different regions and environments. This trait will likely be increasingly important for management of both fungal and viral (Jones and Barbetti, 2012) diseases under the more extreme and variable environmental conditions predicted for future climate scenarios, including regions where Brassica crops are currently, and should remain, economically important Barbetti et al, 2012).…”

Field resistances/susceptibilities against Albugo candida race 2V were determined for 29 Indian Brassica juncea varieties and compared with resistant varieties from China (6) and Australia (7). 'Basanti' (AUDPC incidence 46.7; AUDPC severity 29.2) represents the first high-level resistance to race 2V in Indian varieties. Several others showed lower but still useful levels of resistance, including Narendra Ageti Rai-4 (AUDPC incidence 150.6; AUDPC severity 66.8) and JM1 (AUDPC incidence 167.1; AUDPC severity 83.7). Highly susceptible Indian varieties had AUDPC incidence values >200 and severity >100. 'Basanti' had least stagheads/ plant (0.32), while Narendra Ageti Rai-4 had lowest % plants with stagheads (2.48). In contrast, almost half of Indian varieties had stagheads/ plant >1 and % plants with stagheads >4, and >26 for 'Kranti'. The resistance in 'Basanti' paves the way forward towards significantly improved white rust management in mustard in India. JM06011, JM06021, JR049 from Australia and CJB-003 from China had zero leaf incidence. There were significant (P < 0.001) relationships between disease incidence with severity (R 2 0.92), stagheads/plant (R 2 0.69) and also % plants with stagheads (R 2 0.60); between disease severity with stagheads/plant (R 2 0.68) and also % plants with stagheads (R 2 0.69); and between stagheads/plant with % plants with stagheads (R 2 0.59).
