CRT SA : Spring Big Brands 2012
There’s always better value at CRT. With rain through the sowing window providing a good start to many areas of Australia, if not 4 weeks late in some areas, being able to manage and profit from opportunities by reducing in-crop risk will be essential. Over the last few years many of the new wheat cultivars have had increased levels of resistance to a range of diseases including the rusts, but this does not mean that paddocks can have the gate closed until harvest. Close inspection at critical times of crop development still needs to be practiced to look for any potential disease issues such as stripe, leaf and stem rust or other late infections. Late infections of diseases including stem rust and fusarium head blight in wheat can be devastating on yield, especially if seasonal conditions have caused lower than expected grain production. Late infections of stem rust can still cause decreases in yield and management of the disease using lower cost products such as Folicur or Tilt at the top end of label rates early rather than later can save yield and maximise profit, even in dry seasons for susceptible cultivars. However, with the cost of fungicides falling significantly over the last few years there is the opportunity to use appropriate rates of high quality products such as Prosaro from Bayer CropScience and Amistar Xtra or Tilt Xtra from Syngenta. These products have significant benefits over the use of the older products at low rates including tebuconazole and propiconazole. The newer and more efficacious products such as Prosaro and Amistar Xtra should be used where longer protection is required or control of a specific disease is needed, especially in high production areas or crops that have high yield potentials. Wheat crops that have been supplied with rust protection, either as a seed or fertiliser treatment, should be closely monitored from about 8–10 weeks after sowing to look for the development of rusts. Depending on the different types of resistance in the wheat cultivar the use of in-crop fungicides should be planned as these treatments start to wear off. Crop Protection Close monitoring – the key to a successful crop Maintain the value of your chickpeas With increased areas of chickpeas being planted this year there have been a range of cultivars used with varying management programmes recommended by Pulse Australia as follows: PBA Boundary and PBA HatTrick do not require prophylactic fungicide sprays under normal conditions. However, both Jimbour and Kyabra need to have the two fungicide prophylactic spray program. Timing of the first two sprays is critical because control is difficult or impossible after the disease has taken hold. The first spray must be applied before the first post emergent rain event, or three weeks after emergence or at the three leaf stage, whichever occurs first. The second spray should be applied three weeks after the first spray. However, apply the second spray if two weeks have elapsed since the first spray and rain is forecast. For all crops, if ascochyta is present in the crop, apply a registered fungicide at early podding prior to rain to ensure pods are protected, and high quality, disease free seed is produced. The registered fungicides for use in the management of ascochyta are chlorothalonil (Unite and Barrack), Polyram (metiram) and a range of products containing mancozeb. Apart from ascochyta, botrytis (grey mould) late in the season has the ability to affect seed quality and affect the value of chickpeas at harvest. Seed affected by botrytis can cause seedling death either pre or post the seedling emerging. Products containing mancozeb, metiram and carbendazim are registered for management of botrytis. Most chickpea cultivars are susceptible (S) to botrytis with the exception of Howzat and Moti which are MR. When it comes to ascochyta even cultivars which are rated as MR can suffer significant losses in years like 2010. The key to management of both of these diseases is to monitor crops closely and contact your CRT agronomist as soon as disease is present. More importantly, you should develop a plan to manage both these diseases before they establish in the paddock.
