Plenum

Plenum 50 WG is a systemic insecticide containing pymetrozine (500 g/kg) formulated as water-dispersible granules for control of pollen beetle in winter and spring oilseed rape. It belongs to a novel chemical class with a distinct mode of action, remaining effective against pyrethroid- and neonicotinoid-resistant populations. Applied by spraying once during vegetation from the green-bud to yellow-bud stage at 0.15 to 0.25 kg/ha, it performs reliably across a wide temperature range from plus ten to plus twenty-five degrees.
