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...

Minimise risk of virus by retaining stubble, planting on time and at optimal rate, controlling weeds and ensuring adequate plant nutrition.. These results and a recent report of a closely related polerovirus from Tasmania suggest that it has a very wide geographical range... Soil tests in one 2012 salt affected crop of PBA HatTrick south of Walgett showed chloride levels of 1,770 mg/kg (1:5 H2O) and EC se of 9.8 dS/m at 15-60cm...

Controlling Phytophthora root rot (PRR) in chickpea crops is a two-step process, says Dr Kevin Moore, a plant pathologist from the New South Wales Department of Primary Industries (DPI) in Tamworth... In a paper presented at the March GRDC Research Update in Goondiwindi, Queensland, Dr Moore emphasised that although there are no in-crop control measures for PRR, there are two steps that reduce the risk of damage... Dr Moore leads the chickpea component of a GRDC-funded research project that includes investigating the effects of PRR on commercial chickpea varieties, advanced breeding lines and hybrids with wild relatives of chickpea...

A damaging line-up of five crop pathogens can slash northern region chickpea yields when seasonal conditions are right but new prevention guidelines mean growers are better prepared... We advocate paddock selection to minimise phytophthora root rot as the first priority; then implementation of an appropriate ascochyta blight strategy based on rain forecasts and the level of varietal resistance," Dr Rainbow says. ".. Growers can use paddock selection to reduce inoculum by considering crop sequence, previous occurrence of diseases, proximity to crop residues, and herbicide history, he says...

Dr Moore says growers should be aware of the disease resistance traits of each variety they are growing and have seed tested for germination, vigour and pathogens... "The first thing growers of any crop should do is make sure they've got good quality planting seed because getting crops off to a good start is dependent on the quality of the seed," Dr Moore said... Dr Moore says the resurgence indicates growers are confident about the place the crop has in the farming system and they are equally confident about growing chickpeas...

At Dubbo, from June to November, 318 mm of rain fell on 52 days with 34 days >1.0mm, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... Monitor the crops 2-3weeks after each rain event from emergence onwards and spray if Ascochyta is detected in the crop or is found in the district on any variety... (GMs also take into account other production costs estimated at $300/ha; chickpea price $450/t)..
