New Herbicide Targets Broadleafs

The flowers are attractive, but wild violets are a nuisance in southeastern lawns.

Wild violets can take over lawns in the humid southeastern portion of the country. According to Greg Constantino, Richmond, Va. branch manager for IKEX Inc., (a distributor of horticultural products), a relatively new herbicide can be used on turf to control wild violets and many other hard-to-control broadleaf weeds. It’s called carfentrazone. This material is rain-fast in three hours, and you can reseed the treated area two weeks after application. For violet control, it needs to be used in early to mid-April, when the violets are just starting to grow. Sold as SpeedZone, it has been used in the professional lawn-care industry with exceptional results. It's available at many lawn-and-garden centers.

"While low levels of chemical residue may occur in surface and groundwater, the risk to non-target plants or animals is low," the EPA fact sheet on the substance states. "Carfentrazone is considered to be practically non-toxic to birds. The chemical is moderately toxic to aquatic animals."

Turf Management Series Available from CANGC

SACRAMENTO, Calif—The California Association of Nurseries and Garden Centers' California Certified Nursery Professional Program developed a Turf Management Series available to all industry members to serve as a training resource.

"The [turf series] materials and the quizzes will help green industry professionals in all segments of the industry test their horticultural knowledge," said Elaine Thompson, CANGC president. "We also recommend it for businesses looking to augment employee training."

Businesses and individuals to benefit from the Turf Management Series include landscape contractors, landscape maintenance, parks and recreation departments, golf courses and retail garden centers.

Included in the Turf Management Series are four "specialized" volumes of "Pest Notes from the University of California, which will serve as study materials, as well as a quiz for each volume. The volumes cover the following topics: Grassy Weeds, Broadleaf Weeds, Lawn Pests and Turf Management. The technical information, presented in an easy-to-read fashion, is the basis for the true/false, multiple choice and fill-in-the-blank questions that make up each quiz.

Companies may order copies of the Turf Management Series (all four volumes) for staff training purposes. Company packages include two sets of study materials and five quizzes for each volume. The company training package is $50 for CANGC members and $75 for non-members. For companies with larger staffs, the association also offers custom packages.

Individuals may purchase their own series, or single volumes. Each Turf Management volume costs $7.50; the complete series of four volumes can be purchased for $25.00.

For nursery personnel with CCN Pro(TM) status, the series provides the opportunity to earn continuing education units (CEUs). CCN Pros must pass a brief quiz by a score of 80 percent to earn two CEUs. If all four volumes are purchased as a package and returned to CANGC together, the CCN Pro can earn two bonus CEUS. If all four quizzes are passed at this time, a total of 10 CEUs will be earned; this is the minimum number required every two years to maintain active status.

Thompson suggests that individuals already holding CCN Pro status can use the series as a refresher course in their professional careers.

The Turf Management Series can be purchased online; visit the Certification area of the California Association of Nurseries and Garden Centers website at

February Maintenance Calendar

Early spring is the best time to get invasive bermudagrass under control in warm-weather states. Apply a pre-emergent herbicide to lawns during the first half of February to control weed germination.

February is a growing month for gardens in southern states, with turf maintenance and other tasks competing for attention. Garden columnist Peggy Dessaint offered the following advice to readers of the (Sarasota) Sun Herald.

Fertilize palms, shrubs, perennials, citrus and lawns later this month and into March. Broadcast fertilizer under plant canopies. Use fertilizers that contain extra magnesium, minor elements and a portion of the nitrogen in a "slow release" form.

Fill bare spots in lawns with plugs or pieces of sod now through the fall months. Prepare for large-scale lawn renovations. This takes two to three applications of an herbicide (e.g. Roundup) to kill weeds (especially common Bermuda grass), spaced two to four weeks apart, followed by a final scraping away of old grass and weeds before new sod is laid. Apply a pre-emergent herbicide to lawns during the first half of February to control weed germination. This can be repeated depending on the product, label instructions and budget constraints. Some fertilizers contain pre-emergent herbicides ("weed and feed products"). Replant more herbs. Plant warm season vegetables. Examples are beans, cantaloupes, sweet corn, cucumbers, eggplants, okra, peppers, sweet potatoes, pumpkin, summer and winter squash, tomatoes and watermelon. Prune backyard citrus trees (if needed), roses and crape myrtles. Resist the urge to remove cold-damaged branches and stems until the end of this month for western Manatee County and mid-March for the coolest parts of eastern Manatee.

Bayer Recalls Allectus Granular

Bayer Environmental Science is voluntarily recalling Allectus G and Allectus GC granular products due to visible defects in the packaging. The company said the recall pertains strictly to a packaging issue and is not a product issue in terms of efficacy or performance. There is no known health or safety risk associated with the packaging problem, and is conducting a thorough investigation of the problem involving the proper government authorities in the process. A solvent, benzyl alcohol, in the formulation is permeating and delaminating the packaging causing ink on the printed label to smudge and become illegible. There have been no reported cases of ruptured bags or other packaging issues. In addition, Bayer is placing an immediate stop-sale of the products until the problem has been rectified. It is also communicating to its customers the steps for the proper collection and return of the product. Approximately 3,000 bags of Allectus granular products are estimated to be affected by the voluntary recall.
