The Low Down on Bladex

Bladex was a commercially used weed control herbicide. DuPont, in cooperation with the FDA (Food and Drug Administration) phased out the use of Bladex on cropland in gradual stages, completed in 2002. Bladex was most effective for weed control on peas, vetch, lentils, onions, potatoes, sweet corn, chickpeas, and field beans.

Post-emergent

Bladex was designed as a post-emergent herbicide to kill weeds after they appear. Farmers spread it across fallow fields that developed weeds during a long layover in the winter, or on growing fields developing a weed problem. It was extremely effective for broadleaf weeds and grasses, even those that were difficult to destroy such as black nightshade and nettles.

Application Problems

One of the biggest drawbacks to Bladex as a herbicide is that it required almost perfect soil conditions. It was ineffective in either sandy or clay soil. In sandy or clay soil some crop damage, although temporary, could occur.

User Safety

Although Bladex is not toxic when used in the recommended fashion, use care when applying the chemical. Always wear long-sleeved shirts and long pants to protect the skin from irritation and possible rashes. Bladex is poisonous when absorbed through the skin. Wash skin immediately upon contact. Wear goggles and dust mask when using this or any chemical herbicide. Bladex was not a known carcinogen. As with any chemical, notify the poison control center if anyone swallows the product. Rinse immediately upon contact from eyes.

Application

Bladex had little to no interaction with crops and immediate planting after application caused no problems. Do not apply where run-off into streams, rivers, or other ground water sources exist. While Bladex is not dangerous to crops, double applications do kill crop plants. Do not overlap applications.

Storage

Store in a cool, dry place. Keep Bladex in its original container and keep away from children, pets, or livestock. Transportation vehicles must have a hazardous chemical warning sign posted. Seal all containers tight. Do not store with other chemicals, or seeds, and keep out of direct sunlight. Avoid storing where frost occurs.

Spills and Disposal

Do not flush spills into drains. Soak up with lime. Dispose of chemical in an airtight drum buried in accordance with the FDA.
