Biancolilla. All species were pathogenic on leaves, but only U. consortiale

produced cortical lesions 3-MA in vitro on twigs, thus suggesting its main role in the Olea europaea twig dieback. To our knowledge, this is the first report of A. phaeospermum, P. cladoniicola and U. consortiale as olive pathogens. “
“Fusarium circinatum, the causal agent of pitch canker disease on pines, can be disseminated by wood produced in infested areas. The purpose of the study was to evaluate the effect of wood preservatives, commonly used against sapstain and wood-decay fungi, on growth and sporulation of Fusarium circinatum. Seven active ingredients of antisapstain and anti-wood-decay preservatives were evaluated by their inhibition of mycelial growth. Propiconazole, tebuconazole, and 3-iodo-2-propinyl butyl carbamate (IPBC) were effective against F. circinatum, whereas hydroxycarbonate of cooper was not. An assay was also conducted to evaluate the efficacy of three commercial antisapstain and two anti-wood-decay preservatives on Pinus radiata sapwood blocks Ponatinib that were previously inoculated with Fusarium circinatum. The product with the best efficacy was an antidecay preservative composed of tebuconazole, propiconazole, and dichlofluanid. None of the antisapstain preservatives tested was effective

even though they contained fungicidal ingredients. Effects of dosage, product application, and formulation on the efficacy of these preservatives are discussed. “
“Yellowing symptoms similar to coconut yellow decline phytoplasma disease were observed on lipstick palms (Cyrtostachys renda) in Selangor state, Malaysia. Typical symptoms were yellowing, light green fronds, gradual collapse of older fronds and decline in growth. Polymerase 上海皓元 chain reaction assay was employed to detect phytoplasma in symptomatic lipstick palms. Extracted DNA was amplified from symptomatic lipstick palms by PCR using phytoplasma-universal primer pair P1/P7 followed by R16F2n/R16R2. Phytoplasma presence was confirmed, and the 1250 bp

products were cloned and sequenced. Sequence analysis indicated that the phytoplasmas associated with lipstick yellow frond disease were isolates of ‘Candidatus Phytoplasma asteris’ belonging to the 16SrI group. Virtual RFLP analysis of the resulting profiles revealed that these palm-infecting phytoplasmas belong to subgroup 16SrI-B and a possibly new 16SrI-subgroup. This is the first report of lipstick palm as a new host of aster yellows phytoplasma (16SrI) in Malaysia and worldwide. “
“The complete genome sequence of a Laixi isolate of Peanut stripe virus (PStV-Laixi) from China was determined to be 10, 056 nucleotides in length, excluding the 3′-terminal poly (A) tail. The viral genome contains a single long open reading frame of 9669 nucleotides encoding a polyprotein of 3222 amino acids. The polyprotein was predicted to be cleaved into ten functional proteins by three viral proteases.
