Biathlon is a pre-emergent granular herbicide for control of weeds in field and container production ornamentals, conifers and Christmas trees, grounds maintenance, and other label specified non-crop areas. Biathlon contains the active ingredients oxyfluorfen and prodiamine formulated on the Verge™ granule. The engineered granule provides an unprecedented level of dust reduction resulting in improved worker safety and ease of application. Biathlon applicators are required to wear minimal Personal Protective Equipment (PPE) -- long sleeved shirt, pants and shoes plus socks. Biathlon has a CAUTION label.
Biathlon provides control of a wide range of problem grass and broadleaf weeds by creating a barrier in the soil and is active for several months. Biathlon works by inhibiting cell division and disrupting cell wall formation in shoots and roots of emerging seedling weeds. Users should irrigate before Biathlon application with ½" water to ensure firm soil or media around the root system. After application, Biathlon should be applied when rain is soon forecasted or watered-in with approximately ½" of water. Biathlon should be broadcast evenly over media for maximum performance. To prevent weed escapes, do not disturb the soil or media in Biathlon treated areas; this will disrupt the barrier necessary for successful weed control.
Container and field grown ornamentals, Christmas tree and conifer farms, grounds maintenance ornamentals, cut flower and foliage crops and non-crop land.
Biathlon has shown excellent plant tolerance on a wide variety of ornamentals. Please consult the label for a full list. Crops not listed as tolerant to Biathlon should be evaluated on a small scale for 30-60 days after application for herbicidal injury prior to widespread application.
50 lbs. bag.
Do not apply to wet foliage. Biathlon is a pre-emergent herbicide and will not control established weeds. Biathlon is not labeled for use on vegetable or edible fruit crops, turf, and bedding plants or flowering crops, except as listed in the grounds maintenance section of the label. Avoid application to plants that can channel herbicide to the leaf base (i.e. yucca, dracaena, daylily, hosta etc.). See label for additional restrictions and precautions.
