British Tomato Growers' Association executive officer Gerry Hayman and British Leafy Salads' Association technical coordinator David Norman said the loss was unlikely to lead to significant gaps in disease control. "If we lost it as a seed treatment then that would be a problem," said Norman.
He added that the revocations had not been publicised well enough by the Chemicals Regulation Directorate.
"The loss of thiram could be more significant than we think," said HDC crop protection technical manager Vivian Powell. "We'll look to see if changes to application rates or timings could help."
