Blight spray application on target with 3D ninety
Blight application with the new Syngenta 3D ninety nozzle has shown to get more even spray distribution throughout the crop canopy. Used in conjunction with drift retardant, it proved to give the best and most reliable results in nozzle trials at Eurofins last season.
Reporting results to growers and agronomists at Potato Science Live, Syngenta Application Specialist, Harry Fordham, demonstrated the 55⁰ angled spray pattern was better able to get coverage on the top, middle and bottom leaves.
“With 90% drift reduction we are getting more spray into the crop. Improved penetration helps to protect plants from higher disease risk as a result of greater humidity within the canopy.
“The 3D ninety improves efficacy, increases work rate to take advantage of any spray opportunities and reduces drift – which is good for the environment and getting the best value of an application,” he advised.
Mr Fordham added with the Syngenta Potato Nozzle being withdrawn for manufacture, the 3D ninety will be then nozzle of choice for potato applications when it is launched later this year.
“The 3D ninety has also performed exceptionally well for pre-emergence herbicide applications, to achieve all round coverage of soil surfaces,” he advocated. “It is especially good for potato seedbeds, where the drift reduction minimises issues of shading where any cross wind reduces coverage on one side of the ridge.”
With the steep angled pattern of the 3D ninety that is so effective for potatoes, Mr Fordham advised nozzles should be fitted to alternate spray forwards and backwards along the boom. Apart from directly behind the sprayer where they may need to be pointed backwards to avoid spray hitting the machine.
Responding to growers’ questions, he added the recommended water volume remains at 200 l/ha for both pre-emergence applications and blight sprays in most situations.
