Pendimethalin 30% + Imazethapyr 2% EC is a selective, pre-emergent herbicide used for controlling annual grasses, sedges, and broad-leaved weeds, primarily in soybean crops.
It's an emulsifiable concentrate (EC) combining two active ingredients: Pendimethalin, a microtubule assembly inhibitor that arrests cell division, and Imazethapyr, an ALS inhibitor that stops branched-chain amino acid synthesis.
This dual mode of action provides effective, comprehensive weed control at or before germination.
Pendimethalin 30% + Imazethapyr 2% EC
Absorption: Absorbed by both roots and foliage, then translocated throughout the plant.
How it works: Pre-emergence control: Targets weeds as they germinate from seeds.
Selective: It is formulated to control susceptible weeds while minimizing harm to the soybean crop.
Target crop and weeds: Primary crop: Soybean. Target weeds: Susceptible annual grasses, sedges, and broad-leaved weeds.
Pendimethalin (30%): Family: Dinitroaniline.
Mechanism: Inhibits microtubule assembly, stopping cell division and plant growth, particularly after germination.
Absorption: Absorbed by plant roots and leaves.
Imazethapyr (2%): Family: Imidazolinone.
Mechanism: Inhibits the acetolactate synthase (ALS) enzyme, blocking the synthesis of essential branched-chain amino acids needed for protein and cell production.
