To combat invasive annual and perennial broadleaf weeds, it's usually best to attack them before they emerge with a pre-emergent herbicide.

What is Pendimethalin?

Pendimethalin (chemical name: N-[1-ethylpropyl]-3,4-dimethyl-2,6-dinitrobenzenamine) is a non-selective herbicide specially designed for the control of a broad range of weeds including annual and perennial grasses broadleaf species and woody species. Imazapyr is from the herbicide family imidazolinone.

Pendimethalin was initially registered in 1972 and approved by the EPA for pre-emergent and post-emergent control of a variety broadleaf and grassy weeds on many agricultural crops, such as: cotton, corn, sorghum, peanuts, rice, beans, peas, wheat, potatoes, soybeans, sun- flowers, tobacco, ornamentals, non-bearing fruit and nut crops and vineyards. 

Pendimethalin is a systemic dinitroaniline herbicide which behaves much like the active ingredients oryzalin and trifluralin, the chemical inhibits germination and seedling development. It comes usually as either a granular or an emulsifiable concentrate. In its original form, pendimethalin is a crystal-like solid that appears orange yellowish in color and has a fruity odor. 

How Does Pendimethalin Work?

Pendimethalin’s mode of action is that it 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.

Pendimethalin is a selective herbicides which means that rather than killing all plants the chemical comes into contact with pendimethalin kills only certain kinds of weeds that are detrimental to the desired crop. Target plants include annual grasses and broadleaf weeds.

Is Pendimethalin Safe To Use?

Pendimethalin is considered of low acute toxicity. However, it has caused thyroid problems in male and female rats. Exposure to pendimethalin through diet is extremely low. So is the risk of cancer through this route. In addition, it has been classified as a possible cancer causing substance.

 

Although animal studies show that pendimethalin has a low toxicity, it is slightly toxic if you are exposed to it by eating or drinking contaminated food or water. It is also toxic if it gets in the eyes. Exposure is “practically” non-toxic if you breathe pendimethalin or if it is absorbed through the skin.

 

When using products containing pendimethalin it is imperative to wear the proper clothing, which you can find out by checking the product label. Pendimethalin  is considered "slightly toxic" if ingested, inhaled, or absorbed through the skin.  Handlers of the product are at risk for these kinds of exposures during mixing, loading, and spraying if the proper PPE (personal protective equipment) is not worn.
