Nichino Gem Mancozeb 64% + Metalaxyl 8% WP Systemic & Contact Fungicide
Gem combines systemic racemic Metalaxyl with multi-site contact Mancozeb. It is registered for selected oomycete and blight diseases, but the current manufacturer and regulatory dose records conflict mathematically.
Use note: Do not use a blanket 2 g/L dose or this listing as a dose table. The current physical Gem leaflet must resolve crop-specific rates, water and PHI before application.
