Abstract
Field trials have shown that the length of V. inaequalis ascospore latent periods is superior to that indicated in Mills’ table.
Two models are presented to forecast the end of incubation periods, based upon daily temperature and cultivar sensitivity.
In scab control, the maintenance of fungicide coverage on plants at the end of ascospore latent periods (calculated with these models), gave better results in 1994 than in 1995, especially with surface fungicides and cultivars such as Golden.
The results were obtained by including this technique in a calendar schedule without increasing the number of treatments.
