DUPONT HAS responded to Scottish concerns about spraing control by increasing the maximum rate of Vydate for free-living nematode control in potatoes.

“Last year there was only a 140g/100m row recommendation, which is enough to protect yield against anti-feeding damage,” says the firm’s Neil Beadle.

But Scottish growers’ requirements for a higher rate suitable for greater pest pressure and suppressing spraing has led to a second additional rate of 210g/100m row. “That rate has given equivalent results to the higher Temik rate for preventing nematodes transmitting TRV and suppressing spraying.”
