Pymetrozine
Other Name: (E)-4,5-dihydro-6-methyl-4-[(3-pyridinylmethylene)amino]-1,2,4-triazin-3(2H)-one
CAS Number: [123312-89-0]
Molecular Formula: C10H11N5O
Pymetrozine is a systemic insecticide active against motile forms of Hemiptera, including those with MACE and esterase resistance. It has no knockdown activity but crops are protected immediately because feeding ceases soon after ingestion; this is attributed to the product disabling the pests stylet. The insects die of starvation within a few days. The product is plant-systemic. It is readily taken up by leaves and roots and translocated around the plant; it exhibits excellent translaminar activity. Novartis (now Syngenta) has also demonstrated a reduction of TYLCV transmission by B tabacii (ie reduced vectoring capability) following foliar applications of pymetrozine to tomatoes. Further studies demonstrated that pymetrozine persists in crops for up to 14 days and should offer protection against the transmission of PLRV (potato leaf roll virus).
Pymetrozine is an insecticidal compound which belongs to a new chemical class known as pyridine azomethines. It exhibits a unique mode of action which can be characterized as neural inhibition of feeding behavior. Pymetrozine is a low use rate product which controls aphids at lower rates than most commonly used insecticide standards.

APPLICATIONS
Biochemistry Novel, unidentified biochemistry.
Mode of action
Insecticide selective against Homoptera, causing them to stop feeding.
Uses
Control of aphids and whitefly in vegetables, potatoes, ornamentals, cotton, deciduous and citrus fruit, tobacco, hops; both juvenile and adult stages are susceptible. Also control of planthoppers in rice. Application rates vary from 150 g/ha on potatoes to 200-300 g/ha on ornamentals, tobacco and cotton; 10-30 g/hl on vegetables, fruit and hops.
