A completely new concept in the control of banana leaf diseases is now available to growers with the introduction of Routine 200 SC Fungicide from Bayer.
Routine is a new plant defence activator that is registered for the control of two key leaf diseases in bananas, yellow Sigatoka (or leaf spot) and common leaf speckle. Key to the concept behind Routine is that it acts by mimicking salicylic acid in the plant, so that the natural chemical pathways the plant uses to defend itself are activated.
As Nick Matthews, Bayer Market Development Agronomist in Far North Queensland, explains, this effect does not damage the plant; rather it establishes Systemic Acquired Resistance (SAR), which is not washed away by rainfall and is boosted with each Routine application.
