Serious infestations caused by whiteflies, Bemisia tabaci, two-spotted leafhoppers, tobacco budworms, cabbage worms, Spodoptera exigua, Epilachna beetles and many other pests are difficult to control and have become a major headache for growers. A water-dispersible granule formulated with 10% Chlorantraniliprole + 50% Pymetrozine can control more than 50 kinds of pests, featuring fast action and long residual efficacy.

Pymetrozine is a pyridine insecticide. Once piercing-sucking pests such as aphids, whiteflies, and planthoppers come into contact with it, they almost immediately develop stylet-blocking effects and stop feeding at once. Within 3 hours, aphid feeding activity can be reduced by about 90%, and within 48 hours, mortality can approach 100%.

Chlorantraniliprole belongs to the diamide class of insecticides and can efficiently activate insect ryanodine (muscle) receptors. It causes excessive release of calcium ions from intracellular calcium stores, leading to paralysis and death of the insects. Its insecticidal activity is up to 100 times higher than many other insecticides, making it one of the broadest-spectrum and most effective insecticides currently available.
