Protection of potatoes against diseases when using tank mixtures with a reduced fungicidal rate
Abstract
Optimum tank mixtures of fungicides (Thanos, v.h., Ordan, r., Shirlan 500 SC, KS) with biologically-active compounds — growth regulators (Biolan, r., Stimpo, r., Regoplant, r.), microfertilizer (Oracle, p.), which allowed to reduce the rate of application of fungicides by 50% and to ensure the improvement of quality indicators and increase of potato yield. Investigated biological, economic and economic efficiency, methods, frequency and timing of the optimal use of tank mixtures of fungicides and the reaction of potato varieties to use them.
