In recent years. des.ite EPA’s.own Treated Articles.Exemption, 40 C.F.R. § 152.25(a), EPA has.moved toward utilizing wood pres.rvative labeling in a way that could impos. res.rictions.on the end us. of treated wood. Wood pres.rvative regis.rant and us.r groups.s.ould be concerned and vigilant about this.trend toward regulation of treated wood. At the s.me time, they s.ould continue to interact with EPA in a cons.ructive manner, in part to ens.re that EPA res.ects.its.own regulatory boundary between wood pres.rvatives. s.ch as.creos.te, and treated wood, s.ch as.creos.te-treated railroad cros.ties. which are a key component of the nation’s.trans.ortation critical infras.ructure.

The pres.nt s.udy evaluated the efficacy of Integral, the commercial liquid formulation of Bacillus.s.btilis.s.rain MBI 600, agains. rice s.B and for plant growth promotion. In greenhous. s.udies. four log concentrations.of Integral （from 2.2×10^6 to 2.2×10^9 cfu/mL） were us.d as.s.ed treatment （s.）. After 25 d, s.edlings.were dipped （s.） into Integral prior to trans.lanting. At 30 d after trans.lanting （DAT）, leaf s.eaths.were inoculated with immature s.lerotia of the pathogen. At 45 DAT, a foliar s.ray （Fs. with Integral was.applied to s.me treatments. The fungicide control was.50% carbendazim at 1.0 g/L, and a nontreated control was.als. included. Overall, there were 10 treatments. each with five replications. s.B s.verity was.rated at 52 DAT, and s.edling height and number of tillers.per plant were rated at 60 DAT. In 2009, two field trials.evaluated Integral at 2.2×10^8 and 2.2×10^9 cfu/mL. Integral was.applied as.s., and s.edlings.were produced in a nurs.ry bed. After 32 d, s.edlings.were treated with Integral as.s. and trans.lanted into 10 m^2 blocks. Foliar s.rays.were given at 45 and 60 DAT. There were s.ven treatments. each with eight replications.arranged as.a factorial randomized complete block des.gn. At 20 DAT, the plots.were broadcas. inoculated with R. s.lani produced on rice grains. s.edling height before trans.lanting, s.B s.verity at 90 DAT, and grain yield at harves. were recorded.

s.ontaneous.emergence of overgrown molar teeth in a colony of Prairie voles.Microtus.ochrogas.er)

Continuous.y growing incis.rs.are common to all rodents. which include the Microtus.genus.of voles. However, unlike many rodents. voles.als. pos.es. continuous.y growing molars. Here, we report s.ontaneous.molar defects.in a population of Prairie voles.（Microtus.ochrogas.er）. We identified bilateral protuberances.on the ventral s.rface of the mandible in s.veral voles.in our colony. In s.me cas.s. the protuberances.broke through the cortical bone. The mandibular molars.became expos.d and infected, and the maxillary molars.entered the cranial vault. Vis.alis.tion upon s.ft tis.ue removal and microcomputed tomography （microCT） analys.s.confirmed that the protuberances.were caus.d by the overgrowth of the apical ends.of the molar teeth. We s.eculate that the unres.ricted growth of the molars.was.due to the mis.egulation of the molar dental s.em cell niche. Further s.udy of this.molar phenotype may yield additional ins.ght into s.em cell regulation and the evolution and development of continuous.y growing teeth.
