Amvac Chemical Corporation has announced that the new label and source for Dacthal, a key herbicide for use in specialty crops, have been approved for use in the United States and that the product is now available to growers nationwide through Amvac's distribution.

Dacthal has been used by vegetable growers throughout the world for more than 30 years. When Dacthal is used in a pre-emergent weed control program, it prevents most weeds from competing with the crop. Often no further operations are needed. Weeds that do emerge are weakened and are easier to remove with followup herbicides or mechanical cultivation.

Dacthal is unique, because it can be applied safely in a preplant or pre-emergent program.

The registered uses and use patterns for Dacthal remain unchanged from the previous label.

The product is registered for use on a large number of specialty crops, including onions (all types), broccoli, brussel sprouts, cabbage, cauliflower, Chinese broccoli, Chinese cabbage, rapini, bok choy, gai choy, collards, kale, kohlrabi, mustard greens, rape greens, turnip greens and all other leafy vegetables in the Brassica crop group, field beans, snap beans, mungbeans, southern peas, seeded melons, cucumbers, squash, garlic, horseradish, potatoes, radish, sweet potatoes, yams, tomatoes, eggplant, peppers, strawberries, cotton, turf and 120 ornamental plant species.

Dacthal was previously marketed by ISK Biosciences, which discontinued production four years ago. Amvac, whose corporate strategy is to acquire mature product lines from the large companies, saw an opportunity to add a valuable herbicide to its growing portfolio of specialty products.

Over the past two years, Amvac made an extensive effort to acquire the business and develop a new source of production, which recently was evaluated and approved by EPA.
