Abstract:
The work presents the results of biological efficiency test of the preparation Penconazol EC, Tuoreg 500 WP and Raeoc EC as a fungicide aganist apple’s powdery mildew – Podosphaera leucotricha (Ell. et EV. Salm.) and apple’s scab – Venturia inaequalis (Cke Wint.). The obtained experimental dates proves that the biological efficiency of the fungicide Penconazol EC in a dose of 0,4 l/ha and Tuoreg 500 WP in a dose of 0,2 kg/ha against powdery mildew is on the level of the standard. Using Tuoreg 500WP in a dose of 0,2 kg/ha, against scab, showed that biological efficiency, at leaves, is on the level of the standard and on fruits the biological efficiency is higher than the standard. The preparation Raoec EC as a fungicide, against the scab, in a dose of 0,15 l/ha as at leaves so at fruits showed that the biological efficiency is on the level of the standard and in a dose of 0,2 l/ha the biological efficiency is at a higher level than the standard.
