Pirina control [Elektronische Daten] [P. Tshmir, D. Kolesova] Un indicateur révélant les infections précoces de tavelure du pommier - outil indispensable pour améliorer les stratégies de lutte contre Venturia inaequalis et V pirina Adequate control of apple scab mainly depends upon a good coincidence between infection development and treatment measures. The use of a chemical indicator is described, which allows for any scab spots to be revealed early, i.e. 3-4 days before the lesions become optically visible on the leaves or on the young fruits. It is suggested that this new technique is likely to be very helpful with a view to adjust the timing of the spraying schedule, and hence may contribute to reduce the number of applications needed every year.
