Eficienţa biologică a unor noi produse triazolice în combaterea rapănului mărului – Venturia inaequalis (cke wint.)

Abstract

The work presents the results of the biological efficiency test of the preparation Propistock 250 EC and Taspa 500 EC as a fungicide aganist apple’s scab – Venturia inaequalis (Cke Wint.). The obtained experimental data prove that the biological efficiency of the fungicide Propistock 250 EC in a dose of 0,4 l/ha and Taspa 500 EC in a dose of 0,15 l/ha against apple’s scab is on the level of the standard. Using Propistock 250 EC - 0,5 l/ha and Taspa 500 EC - 0,2 l/ha, against scab, showed that the biological efficiency is on the level of the standard. After testing the preparations Propistock 250 EC and Taspa 500 EC, they were implemented in the integrated protection system on apple plantations against scab.
