| Abstract/Contents: | "Broadleaf weed control is an important component of turfgrass management. Limited information exists on the residul activity of isoxaben for weed control in turf. A study was established in 1994 at Blacksburg as a randomized complete design with four replications in 'Plush' Kentucky bluegrass (Poa pratensis L.). Prior to preemergence treatments, the plots were detached and fertilized with nitrogen at 0.54 kg/100m2. A postmergence application of 2,4-D amine plus triclopyr amine was applied over the whole study area to control existing broadleaf weeds. Turf was mowed at a height of 3 cm and irrigated when needed. A 75% dry flowable formulation of isoxaben applied at 0.56, 0.83, and 1.12 kg ai/ha was compared to a granular formulation of oxadiazon applied at 3.36 kg ai/ha. Application timings consisted of spring treatment, fall treatment, and spring followed by fall treatment. Spring preemergence treatments were applied on May 18, 1994. Fall treatments were applied on October 6, 1994. All treated check plots were seeded in rows with white sweet clover, dandelion, and buckhorn plantain. Data collection included weed counts of seeded as well as naturally existing broadleaf weeds. Percent cover of a mixture of large crabgrass (Digitaria sanguinalis L.) smooth crabgrass (Digitaria ischaemum Schreb. ex Schweig.) was also monitored during early summer. Following spring treatments in 1994, complete control of dandelion (Taraxiam officinale L.) and white sweet clover (Melilotus alba Medic.) was seen at approximately 6 weeks after treatment (WAT) with all three rates of isoxaben. Isoxaben provided >90% control of buckhorn plantain (Plantago lancelota L.) and 85% control of dandelion at 15 WAT. Oxaidazion provided no control of buckhorn plantain, but controlled dandelion 61% at 15 WAT. Weed counts taken 8 months after fall (1994) treatment indicated that isoxaben provided at least 95% control of buckhorn plantain. Dandelion control at this time ranged from 50% to 70% in plots that received isoxaben. Oxadiazon did not exhibit any residual activity for broadleaf weed control during the following season. No control of prostrate spurge was recorded for isoxaben or oxadiazon when evaluated 8 months after fall application. Isoxaben applied in spring 1994 did not control any broadleaf weeds when the plots were evaluated a year later. When evaluated in the spring of 1995, plots that received isoxaben in the spring of 1994 followed by fall did not provide greater weed control than the same treatments applied only in the fall. Multiple applications of oxadiazon in 1994 reduced crabgrass cover in 1995 compared to control plots. Isoxaben did not possess any long term activity for crabgrass control." |
