SOME ASPECTS IN THE CONTROL OF SHARKA (PLUM POX) VIRUS DISEASE
This disease has been detected in many European countries, but for some countries such as Yugoslavia, Bulgaria and Czechoslovakia is of special significance (Kassanis and Sutic, 1965; Sutic and Pine, 1968).
To date this disease has not been detected in U.S.A. Nevertheless, due to the great danger of this disease, and certain similarities in the symptoms to some other virus diseases, which appear on various other Prunus sp. in the U.S.A., there is a great interest for this disease (Pine and Sutic, 1968).
Nowadays numerous investigators work on the study of sarka disease. To date significant results have been achieved in the study of its etiology, herbaceous and ligneous host plants of the virus, vectors of the virus etc. However, only a small number of authors dealt in experimental work in the control of virus, hence because of its importance, it would be desirable to enlarge and intensify this work.
In our desire to stress the importance of this kind of investigations we have chosen the subject of control measures against the sarka disease for our present report. By giving the date on some control measures and certain ideas for further studies, we hope that the participators in this conference will kindly give their own suggestions for further investigations in this field of work.
