Effect of botryticides and intensity attack of B. cinerea Pers. ex. Fr. on Grasevina and Traminac cv. in eastern Croatia
During 2001/2002 experiments made in the vineyards of Kutjevo, the examinations were made on the intensity of infection with Botrytis cinerea Pers., the efficiency of the applied botryticides, the achieved grape production and the impact of meteorological factors on the development and intensity of the disease. Among the examined culivars of Grasevina and Traminac, the intensity of infection with Botrytis in both years and on all localities was the highest on the check fields, which therefore indicates a justified and appropriate use of fungicides. The examined efficiency of fungicides applied throughout all four phenophases of the vine development indicates the differences in their efficiency according to sorts and localities as well as the length of examination. With the cv. Traminac the best efficiency was achieved with the Switch 62, 5 WG (fludioxonil+ciprodinil), somewhat weaker efficiency with the Mythos SC (pirimetanil), and on the last place is the Kidan SC (iprodion). With the cv. Grasevina the best efficiency was achieved with the Teldor SC (fenhexamid), insignificantly weaker efficiency with the Switch 62, 5 WG, and on the last place is the combination of Folicur EW 50 (diclofluanid+tebuconazol) + Euparen 50 WP (diclofluanid). The production of grape achieved in the years of examination on certain localities did not show the expected results, since the unfavourable climatic conditions (too much humidity) in both years caused the extraordinary attack of the grey mould of grapes. The weakest production was achieved on the check fields with Traminac as well as with Grasevina, whereas a better production was achieved with the sorts treated with fungicides, according to their efficiency. There is a significant impact of climatic factors (precipitation and temperatures) on the intensity of infection, the efficiency of fungicides and the achieved production of grape. Both years of examination in the months of grape ripening abounded in great quantities of rain. In 2001 the six-month average (May-October) of the total quantity of rain was 504.4 mm, and in 2002 531.5 mm. Such a considerable amount of humidity in vineyards and the proportional variety of temperatures represent the perfect conditions for the development of Botrytis. The stated results indicate that the use of fungicides in the prevention of grey mould of grapes represents an indispensable protection measure with the scope to achieve high production of quality and healthy grapes.
