Sažetak
THE STATUS OF INTEGRATED CONTROL OF POME FRUIT DISEASES IN YUGOSLAVIA-In intensive fruit plantations apple orchards occupie the greatest growing aerea in Yugoslavia, so a lot of attention is given to its protection. Since 1980 a working group has been studying possibilities to introduce an integrated control system in apple plantations. This working group has at least one representative from each Republic and Autonoumous Province. In this way a view over protection of major plantations in Yugoslavia is obtained. The coordinator of this project is the Institute of Plant Protection Zagreb. Although the group has officiaiy been working since 1980 the organization for controlling the apple scab started as soon as each plantation was set up. The first de Wit wetness recorder was used in 1965 on our largest plantation in Borinci. As Yugoslavia differs considerably in its geographical aspects, so the plantations are situated in different climatical conditions. Some apple orchards were planted at 700 rn above sea level, others in typical low land, or on sandy soil. All this greatly influences the appearance and development of diseases and the program of their control. In the past not in all orchards was available the same technical equipment. Regarding this the Ministry of Agriculture suggested to continue supen/ised control with rational use of fungicides, were it had been started, and to start it in other places. Today the largest plantations in Yugoslavia are included into this program (Borinci 750 m ; Agrokombinat Maribor 62 ha ; Bosanska Gradiska 87 ha ; Gradinar-Ohrid 93 ha ; PKB-Ocagd'and Vobis 185 ha and others) ; in total an orchard aerea of 1520 ha. All above mentioned plantations are equiped with one or more instruments for monitoring leaf wetness, ex. de Wit. Bio-. mat, Lufft, Forecast-Zagreb and there are also negotiations for obtaining KMS-P (Graz). In view of the choice of fungicides we are using protective and curative fungicides as in other European countries. In the control of apple scab we are trying to rationalize protection by curative programs i. e. by treating with fungicides after infective rains. On the basis of the results in small plots (which we shall present), we can conclude that the program of supervised scab control has given the same or better results than the standard protective program. In addition it ought to be emphasized that the supervised program of apple scab control required 2 - 3 sprayings less every year than the standard protective program. But applying the eurative program in large operations was hazardous in some cases because of the difficulty to spray every orchard in time.
