HPM Pymetro Plus Pymetrozine 50% WG Insecticide
HPM Pymetro Plus is a systemic insecticide containing Pymetrozine 50% WG. Its approved Indian label use is for the management of brown planthopper (BPH) in paddy.
Pymetrozine belongs to IRAC Group 9B, the pyridine azomethine derivatives. It acts on chordotonal organ TRPV channels and disrupts the pest's feeding behaviour. Feeding stops after exposure, helping protect the crop from continued hopper damage. Use Pymetro Plus as one part of an integrated pest-management programme and rotate with insecticides from a different IRAC group when another treatment is required.
