Potato crops have paid a heavy penalty as a result of this summer’s record-breaking temperatures and drought, though biostimulant-treated plants appear to have fared better, according to Syngenta trials. First digs from this year’s Quantis heat-stress biostimulant field trials suggest yields may be over 30% lower in untreated crops. Across a series of trials from the south-east to the mid-west, marketable yields are on average 24% higher in the Quantis treated areas. The total tuber numbers in marketable size grades have been on average 34% greater in the treated areas, reported Syngenta technical manager, Andy Cunningham. ‘Hugely beneficial’ “What appears apparent is that a Quantis application at early tuber initiation has been hugely beneficial in helping plants to set more tubers. “Importantly, further applications during periods of heat stress through the growing season has enabled crops to keep growing and produce more marketable yield.” All the trials yielded so far had received an application at tuber initiation, with two additional treatments during the tuber filling growth stages – at timings when the Quantis Heat Stress Alert tool forecast periods of challenging conditions. “Quantis research has shown best results can be achieved with applications two to three days prior to onset…
