Overview
ETHIRIMOL is a heterocyclic fungicide absorbed via leaves and roots, significantly inhibiting the growth of cucumber powdery mildew mycelium.
Mechanism of Action
It has strong killing effects on mycelium, conidia, and fertilized hyphae, can strongly inhibit spore formation, block sources of re-infection, and provides comprehensive and thorough fungicidal effects. For crops already infected, ETHIRIMOL works well as a treatment, removing pathogens that have entered the plant and significantly suppressing further spread.
