For example, at Dubbo 407 mm of rain fell on 68 days (39 days >1.0mm) between 01 June and 30 November, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... The pattern encouraged rapid vegetative growth of crops and was ideal for the build-up and spread of the major chickpea pathogens... Ascochyta blight (AB, caused by Ascochyta rabiei ), Botrytis grey mould (BGM, caused by Botrytis cinerea ), Phytophthora root rot (PRR, caused by Phytophthora medicaginis ) and Sclerotinia rot (caused by Sclerotinia sclerotiorum and Sclerotinia minor ) were widespread and severe in many crops...

Ascochyta confirmed in CQ chickpea crop.. Dr Moore urged growers to vigilantly monitor crops for early signs of Ascochyta blight infection, particularly given above average winter rain in many areas and the Bureau of Meteorology's forecast of neutral to La Ni a climate conditions by spring for northern Australia... "BGM could present more of a threat to crops this season than Ascochyta with the mild, wet conditions in winter producing high biomass crops and this, coupled with a wet spring will favour BGM."..

New South Wales Department of Primary Industries (NSW DPI) senior plant pathologist Dr Kevin Moore says current forecasts for above average winter rain and neutral to La Ni a conditions in spring, plus evidence that the ascochyta blight fungus is changing and concerns about varietal purity, justify a conservative approach to ascochyta management this season... Chickpea growers in Queensland and New South Wales are being urged to take a proactive approach to disease management strategies this season in response to an updated climate outlook for winter and spring 2016... Recent forecasts issued by the Bureau of Meteorology suggest an increased likelihood of above average winter rain and the onset of neutral to La Ni a climate conditions by spring for northern Australia...

Central Queensland chickpea growers are urged to be on the lookout for ascochyta blight and be ready to apply a fungicide in order to prevent yield loss or seed damage for next year's planting... Julie Ferguson, Department of Employment, Economic Development and Innovation (DEEDI) industry development officer (pulse and grain legumes) says CQ chickpeas are more at risk from ascochyta infection this season than ever before and growers should keep a close eye on their crops right up until harvest... While ascochyta has not been found north of Emerald, it has made its way into chickpea crops scattered throughout CQ's southern growing areas, and Ms Ferguson says a wet end to the growing season could see ascochyta appear in crops as late as at harvest, rendering seed unusable for planting the following year...
