WITH the regulatory decision not to re-authorise oxamyl, growers now to Nemathorin for the control of PCN need to be aware of how to get the best results from this season’s applications, Syngenta's Technical Manager Michael Tait has advised.
“The same equipment can be used for the overall application of granules, however it must be fitted with Nemathorin specific rotors or cartridges and calibrated to accurately deliver the 30 kg/ha application rate for PCN,” he advised. “Nemathorin cannot be applied in-furrow.”
Michael advocated incorporating Nemathorin granules evenly to a depth of 15cm in the soil profile during seedbed preparation, immediately prior to planting.
“Incorporation to a consistent depth across all soil types and conditions is important, as Nemathorin is relatively immobile in the soil profile - which helps to achieve the good levels of PCN control,” he saidd. “If field conditions change, check the incorporation depth and adjust accordingly.”
