WHILE high fungal disease pressure on winter pulse crops is anticipated again in 2017, a range of new minor use permits obtained by Pulses Australia, including two for fungicides in the ADAMA Australia range, will ensure the industry is equipped to prevent significant impact, according to ADAMA’s newly appointed fungicide and insecticide portfolio manager, Dror Dagan.
“ADAMA welcomed industry applying for permits to use its products, especially where the company was confident of a strong fit and for uses for which the company was pursuing full registrations,” Mr Dagan said.
“Last year’s use under permit of new fungicide Veritas® in chickpeas and lentils was a prime example where a product able to be used under permit performed strongly and was well received.
“Veritas® remains permitted for use in chickpeas and lentils until 30 September, and because it brings a new fungicide mode-of-action into the equation with a unique formulation, it remains an outstanding option to control pulse fungal diseases with additional crop health benefits.
“Given reduced sensitivity and resistance to fungicides in other crops has already been observed, new fungicide modes-of-action are welcome additions to our fungicide options.
“The development of fungicide resistance could be closer than we think in these crops and we should be proactive in our management approach,” he said.
A global shortage of chlorothalonil, a traditional fungicide with a multisite mode-of-action used to manage disease in pulse crops, has also contributed to motivate the industry to seek additional registrations and permits for newer technology fungicides for use in pulse crops this year, according to Mr Dagan.
“It is pleasing that Pulse Australia have recognized the effectiveness and potential contribution of Veritas® this season and sought a permit,” Mr Dagan said.
“Likewise, it is pleasing Pulse Australia could obtain a permit to use Solaris® this season, which is another new mode-of-action fungicide for pulses from the ADAMA range.
“The ability to use Veritas® in Faba Beans as well as Solaris® in Chickpeas this season is an excellent outcome for growers and we know, based on many grower enquiries received by us, satisfies one of their key wants for this season.
“We know these products perform well, and we are in the process of applying for full registration of Veritas® for use in Faba Beans and have conducted several years of efficacy trials.
“Veritas® offers excellent control of Chocolate Spot and Ascochyta Blight in Faba Beans comparable with its excellent performance on Aschochyta Blight and Botrytis Grey Mould in commercial Chickpea and Lentil crops last year,” he said.
The permit to use Solaris® in chickpeas introduces a welcome new mode-of-action for the control of Aschochyta Blight, Mr Dagan said.
“Solaris® has traditionally been deployed for high level disease control in grapes and pome fruit, but having it as a an option for use in chickpeas is very handy, especially if disease pressure hits hard over the coming months,” he said.
“Our screening work demonstrated cyprodinil, which is the active ingredient in Solaris®, provided robust control of Aschochyta in chickpeas and could be an excellent alternative to other mainstream options.”
According to industry experts, the high incidence of Ascochyta Blight fungal disease in 2016 chickpea crops across Queensland and Northern NSW has led to substantial stores of inoculum ready to infect 2017 chickpea crops, and reports of significant disease already in early planted crops in the north appear to evidence that concern.
The photos on the right show the excellent level of control that Veritas gave in a trial run by FAR at Westmere in Victoria last year where disease levels where extremely high and untreated sections of the trial were a complete right off. A two spray program of Veritas maintained the crop in relatively disease free state through to harvest.
