What is pendimethalin?
Pendimethalin is the active ingredient found in the popular weed preventer Pendulum 2G. It is an orange-yellow crystalline solid with a slight nutty or fruit-like smell. Pendimethalin is globally registered for use on a wide range of food crops.
What is a selective herbicide?
Selective herbicides are just what you would think. Rather than killing all plants indiscriminately, pendimethalin kills only certain kinds of weeds that are detrimental to the desired crop. Target plants include annual grasses and broadleaf weeds.
What is the best timing for pendamethalin products?
Products containing the active ingredient pendimethalin can be used both preemergence (before target weeds emerge) or early postemergence (just after weeds have sprouted).
Mode of Action
Pendamethalin is an inhibitor of plant cell division and cell elongation. It is absorbed into the target plant at the roots and shoots and the plant is no longer able to grow.
Animal & Environmental Toxicity
Pendimethalin is highly toxic to fish, but non-toxic to birds. It will not leach through the soil to contaminate ground water. Garden products that contain pendimethalin must carry the word "Caution" or "Warning".
When handling products that contain pendamethalin it is imperative to wear the proper clothing, which should be outlined for you on the product label. This chemical is considered "slightly toxic" if ingested, inhaled, or absorbed through the skin. Applicators of this product are at risk for these kinds of exposures during mixing, loading, and spraying if the proper clothing is not worn.
