Howler EVO is a biological fungicide containing the active ingredient Pseudomonas chlororaphis strain AFS009. It is classified under FRAC Group BM02 and is used to control various fungal diseases in plants. This product is versatile and can be applied to crops through several methods, including foliar sprays, soil drenches, shanked-in and injected applications, transplant water applications, tray drenches, and chemigation. It is also suitable for use in hydroponic growth systems. For professional use, it can be applied via aerial methods or through irrigation systems (chemigation) provided specific requirements are met. When using chemigation, ensure the system is properly calibrated and includes necessary safety devices like backflow preventers. For aerial applications, maintain specific heights and monitor wind speeds to manage drift. Users should be aware of environmental hazards and follow strict directions for use to prevent unintended drift. Always maintain agitation when mixing and applying to ensure a uniform solution.
