CRT SA : Winning Autumn Deals 2012
There’s always better value at CRT. Seed treatments set up the crop In this new age of farming where the adage is ‘if it’s not on the seed it’s in the seed’, a number of companies are involved in developing seed treatment products to increase the yield and profit of Australian crops. The key diseases traditionally targeted by seed treatments are smuts and bunts which have the capacity to cause millions of dollars of damage. The development of products such as Raxil® Pro, which includes 250g/L of prothioconzole (the same active used in Prosaro® fungicide) will control the range of smuts and bunts across wheat, barley and oats. Recent developments in seed treatments have seen other diseases targeted by products such as Dividend® M (difenoconazole 92g/L + metalaxyl-m 23g/L) which has the ability to control both smuts and bunts as well as pythium (damping off). It can also suppress diseases such as rhizoctonia (bare patch) in wheat and barley. Dividend M has proven itself to be of real benefit to farmers where the move to minimum and zero till has seen disease levels increase. Control of smuts and bunts and the management of pythium with Dividend M is 130mL/100kg of seed but the rate needs to be increased to 260mL/100kg of seed to suppress rhizoctonia. One of the mixing partners that can be used with Dividend M is the insecticide EmergeTM which has the ability to reduce the effects of Barley Yellow Dwarf Virus through the control of aphids early in a crop’s development. For the first time in Australian agriculture there are five different pre-emergent herbicides from different resistance groups for grain growers to use. This allows an unprecedented level of flexibility in product and crop selection to assist with the management of herbicide resistant annual ryegrass. Even though there is an increasing level of resistance to Group D herbicides such as trifluralin and pendimethalin, the new products hitting the paddocks are able to overcome these issues. At present there are no recorded incidents of cross-resistance to the new products which include Sakura® (Bayer CropSciences), Boxer Gold® (Syngenta) and the yet to be released and registered Outlook (Crop Care Australia). Even better for Australian farmers is that each of these products, together with trifluralin products such as Triflur X® and tri-allates including Avadex Xtra®, all have differences in where they fit into the cropping program. To combat the development of Group D resistance, products such as Triflur X (which is a Group D product) have been mixed with tri-allate or Avadex Xtra at high rates. This combination has provided significant synergistic improvements to the control of annual ryegrass. The initial stand-alone rates of trilfuralin were, by today’s standard, very low with trifluralin products used at rates of 800mL/ha and mixed with a range of Group B herbicides. Practices developed in areas where there has been developing Group D herbicide resistance have been to increase the rate of trifluralin from Crop Protection Pre-emergent herbicides rise from the ashes Boxer Gold® Syngenta released Boxer Gold which is a mix of 800g/L prosulfocarb plus 120g/L s-metolachlor. This combination of two different herbicide groups (J and K) provides real benefits in areas where there is Group D resistant annual ryegrass. Boxer Gold is also registered for the control of toad rush and can be used in wheat (including durum varieties) and barley. One of the major concerns about using pre-emergent herbicides, especially in years that look dry, is the time to incorporation. Boxer Gold is leading the field with a registered time to incorporation of seven days which can be essential in ensuring maximum results. The use rate for Boxer is 2.5L/ha in at least 50L/ha of water, however, better results can be gained through increasing the water rate to 70L/ha. Possible tank mixes with Boxer Gold are extensive and include adding trifluralin at a range of rates to improve efficacy on a number of different weeds. Results from the use of Boxer Gold around Australia have been excellent especially where used in problem areas. For more information on how to get the best results from Boxer Gold contact your local CRT agronomist for local recommendations. Sakura® Sakura (850g/kg pyroxasulfone), as with the other pre-emergent herbicides, is a soil applied, residual herbicide. Sakura’s first registration will be for the management of annual ryegrass, barley grass, annual phalaris, silver grass and toad rush in wheat (not durum) and triticale. Sakura is absorbed by the roots and, to a lesser extent, the shoots of germinating weeds. It works by inhibiting growth in the meristematic area. As with all pre-emergent herbicides, efficacy is improved by applying to moist soil prior to incorporation by sowing and before rainfall to ensure weeds germinate.
