Apple scab, caused by Venturia inaequalis, is one of the most serious diseases of apple throughout the Europe. In our experiments the ascosporous mortality were compared using different plant extracts. These were: Artemisinin 3% and 6% (Artemisia annua), Chelidonine 3% and 6% (Chelidonium maius), Menthol 3% and 6% (Mentha piperita), Populin 3% and 6% (Populus nigra), Linalool + Linalyl acetate + Linalyl acetate 3% and 6% (Salvia sclarea), Thymol 3% and 6% (Thymus vulgaris) and distillate water as control. All extracts used has high mortality effects and very low ascosporous germinated after treatments. All extracts used were also tested in field experiment in vegetable crops. The results were similar, and the mortality of ascosporous also high. These results suggest that the chemical component of the extract has high fungicide effects, and they could be used as biopesticides in integrated and biological control of the apple scab.
