“Infinito (fluopicolide + propamocarb), Percos, Ranman (cyazofamid), Revus and Valbon are the products of choice here,” he advises.  “In France, Valbon demonstrated its consistent position amongst new chemistry, working extremely well, and continuing to be a key product that we’ll be using across the Agrii group this season.” Then, alternating protectant activity, we go from Ranman or Roxam, plus cymoxanil if pressure is high, to those with systemicity and curative action, explains Malcolm. “During the first half of stable canopy this will see us applying Valbon or Percos. “Then in the second half of stable canopy, alternating back to the protectant products and those with a degree of curative activity – Infinito, Revus or Percos.”   Malcolm reports that although Valbon offers good  curative activity and is suitable for the later stage of stable canopy, it fits more logically early on in the first half of stable canopy, to make the most of its good systemicity against foliar blight. “We will then tend to use Revus in the second half if Valbon is used earlier because they are from the same chemical group, so it’s important to alternate for resistance management purposes.” “Finally, into senescence, at the end of growth we will then switch back to Ranman, as the preferable treatment against tuber blight, or Shirlan,” adds Malcolm. Application advice Malcolm urges that throughout the entire blight spray programme this season it’s very important to sustain application rates and keep spray intervals tight. “There is no reason to go on with less than the maximum, full recommended rate or to stretch application intervals, he advises. “It is not enough to prevent today’s current blight population establishing in crops. And regardless of weather conditions he points out that irrigated crops will continue to provide ideal blight conducive conditions which demand a robust and sustained programme with a high level of application efficacy. The role of adjuvants alongside blight sprays this season offers significant benefits, believes both Malcolm Smith and Dr Tudor Dawkins, Certis’ technical manager. “We are now recommending that all blight sprays are applied with an adjuvant this season. Banka in particular has shown good trials data and improvement in control and yields achieved  with all blight fungicides,” notes Malcolm.  “Increasingly the role of adjuvants in blight spray programmes is recognised against today’s blight threat,” believes Dr Dawkins. “Particularly where complete spray coverage isn’t possible. It’s an eventuality that comes with dire consequence,” he believes.   “In recent trials Valbon has been performing consistently as a top player, even where set against new chemistry now entering the market, with no fall off in activity.  “The addition of adjuvant ZinZan to Valbon applications is a recommendation which has been explored by Certis ahead of this season to ensure the most robust treatment during severe blight pressure,” notes Dr Dawkins. The work follows initial observations of the tank mixture made at Eurofins trials in 2010, indicating enhanced protection to new foliage, controlling blight development. Plant pathologist and Associate Professor at the University of Nottingham, Dr Stephen Rossall was tasked with conducting independent trials work with the fungicide-adjuvant mix to explore the initial findings observed at Eurofins and substantiate any tank mix benefits.  The aim was to determine the full impact of ZinZan on redistributing Valbon to unprotected growth and to evaluate the systemicity of this blight fungicide treatment with other industry standards and an untreated control. He explains that three and five days after applying the various fungicide treatments, upper leaves immediately above the sprayed foliage were inoculated with a virulent culture of 13-A2 blight spores. “Then seven days after inoculation, measurements of the blight development in terms of the diameter of blight lesions, were used to determine if there had been any fungicide movement into the untreated growth. “Significantly less blight was recorded in the unsprayed upper canopy leaves for those plants that had been treated with Valbon plus ZinZan,” he noted.  The addition of ZinZan to the Valbon fungicide formulation appeared to have enhanced the systemic movement. “With ZinZan thus delivering a beneficial effect on improving systemic movement and uptake of Valbon, giving protection to newly emerging leaves.” “Findings corroborated field performance, with Valbon + ZinZan acting to improve the window of crop protection, with a degree of control on newly emerged foliage,” comments Dr Rossall “A preventative test, comparing sprayed leaves which were inoculated with blight spores also revealed Valbon plus ZinZan as achieving the lowest level of blight development alongside one other treatment. “The addition and subsequent effect of ZinZan is an important development,” notes Dr Dawkins, adding to Valbon’s complementary ‘kick-back’ activity against leaf and stem blight. “And helping to get the blight fungicide material in to the plant and up the stems.” ZinZan is approved for use alongside Valbon at all labelled growth stages of application, right up until seven days before harvest. This differs from other adjuvants that are only permitted until tuber initiation. “The findings have been impressive, further illustrating the product competence – particularly under high blight pressure conditions where spray intervals have been stretched or rainfall is imminent,” believes Dr Dawkins.]]> News - UK - Archive Sun, 29 Apr 2012 12:44:00 +0200 http://www.certiseurope.co.uk/detail/article/how-to-win-the-blight-battle.html The weather, an unpredictable entity, is the number-one factor in determining how significant...

The fruits are inedible causing significant yield loss, and in some instances, death of the entire crown,” he notes. “Prompt removal of dead and decaying plant material is an effective means of cultural control,” highlights Morley. “But given the levels of inoculum able to initiate infection this spring, it may be necessary to apply a prompt, preventative, fungicide in some cases. “This is particularly important given the limited options for the curative control of the disease.” He recommends employing IPM compatible products such as Frupica SC (mepanipyrim) as early as possible. “For best results two applications of Frupica should be made in a sequence to build up the level of active ingredient on the leaf and guard against infection. “Applications should be targeted around the petals of the plant before disease entry to prevent access of the disease and development of mould,” he stresses. Maintaining ventilation and air flow around the plant is also important to prevent a moist, still microclimate developing and favouring the spread of the disease. -ENDS-]]> News - UK - Archive Mon, 12 Mar 2012 13:01:00 +0100
