Problem Statement and Purpose. The problem scientific and research laboratory of geography and soil conservation of the black soil zone (PSCL‑4 ONU) was opened at the Geology and Geography Faculty of Odessa University half a century ago, in 1971. The main task of the research laboratory resided in conducting soil researches in the steppe zone of the south of Ukraine in connection with the commencement of irrigation programs there, soil and land mapping to streamline their use. The aimof this article is to highlight the major milestones of the half-century history of the research laboratory, as

Abstract:

Due to the narrow window of ideal moisture conditions required for collecting undisturbed soil samples from hardsetting horizons in the field, this study compared the efficiency of an alternative method of soil core removal in the laboratory with that of the traditional field method by using measurements of soil bulk density data (Db). In a first sampling, cylinders were removed with a soil sampler in the field. In a second sampling, large soil blocks were removed with Kubiena-type zinc (brass) boxes in the field. Volumetric core cylinder samples were removed from these blocks in the laborator

Abstract:

In May 2011, samples of lavender plants (Lavandula × intermedia) showing wilt symptoms were collected from two commercial plantings in Slavonia County. Disease was observed on 20 to 30% of the plants. Symptoms of the disease consisted of chlorosis, stunting, wilting, and death. Vascular tissue of stems and roots exhibited brown discoloration. Isolations of the pathogen were made from the discolored tissues on potato dextrose agar (PDA). Colonies were initially white, but with age became red, and red pigments were produced in agar. Microconidia were pear shaped, oval, and fusoid, and ranged fro

Annually, ~20 ha of sweet basil (Ocimum basilicum L.) are cultivated in greenhouses in the green belt area surrounding La Plata, Argentina, mainly for fresh consumption. In 2004 to 2007, basil plants of cv. Genovese showed wilt symptoms, necrosis of leaves and stems, asymmetrical growth, and discolored vascular tissue in greenhouses in La Plata. In 2007, the same symptoms were observed on plants of cv. Morada grown from seeds that were produced in Italy. Isolations were completed from root, crown, and stem sections of diseased plants of cv.

Fusarium spp. are widespread soilborne pathogens that cause important soybean diseases such as damping-off, root rot, Fusarium wilt, and sudden death syndrome. At least 12 species of Fusarium, including F. proliferatum, have been associated with soybean roots, but their relative aggressiveness as root rot pathogens is not known and pathogenicity has not been established for all reported species (2). In collaboration with 12 Iowa State University extension specialists, soybean roots were arbitrarily sampled from three fields in each of 98 Iowa counties from 2007 to 2009. Ten plants were collect

Abstract:

Trinidad is a major exporter of pumpkins (Cucurbita pepo L.) to other Caribbean countries, Canada, and the United States. Producers and exporters have reported 50 to 80% yield losses because of soft rot and overnight collapse of fruit at the pre- and postharvest stages. Severe fruit rot occurred in fields in Victoria County in South Trinidad between April and May 2006 (mid-to-late dry season) with an increase in the severity and number of affected fruit in the rainy season (July to December). Symptoms began as water-soaked lesions on the fruit of any age at the point of contact with the soil.

Beet necrotic yellow vein virus (BNYVV) is an economically important pathogen of sugar beet (Beta vulgaris var. saccharifera) in several European, and Asian countries and in the United States (3). The virus is transmitted by the soil-inhabiting plasmodiophorid Polymyxa betae and causes the rhizomania disease of sugar beet. In November 2012, plants of B. vulgaris subsp. vulgaris cv. Boro (red table beet) exhibiting mainly severe characteristic root symptom of rhizomania were found in a commercial field located in the municipality of São José do Rio Pardo, State of São Paulo, Brazil.

The Aleppo pine (Pinus halepensis Mill.) is a conifer native to the Mediterranean region. In autumn and spring of 2008 to 2009, a survey of Aleppo pine seedling diseases was carried out in three forest nurseries from the Relizane, Sidi Bel Abbes, and Tlemcen departments in northwestern Algeria. Aleppo pine seedlings were potted from the soil. In all three nurseries, 1- to 2-month old seedlings showed symptoms of damping-off disease in pre- and post-emergence (collar rot) with a disease incidence of 64, 77, and 72%, respectively. Disinfected collar segments, about 5 mm in length, were plated on

Juglans sigllata Dode, known as the iron walnut, is widely planted in Liangshan prefecture of southwest China for its nuts and wood. Liangshan prefecture is a major traditional growing area of J. sigllata and has unique advantages for walnut industrial development because of its good soil, climate, and availability of water. Currently there are 2.7 million hectares of walnut, contributing important incomes for farmers. In April 2013, numerous J. sigllata were found infected with root rot in the Muli county of Liangshan prefecture. Symptoms included dried leaves, dead branchcs, and even death.

Symptoms consisted of foliage wilt, plant stunting and drying, and death of older leaves. Internal vascular and cortical tissues of plant crowns showed an orange to brown discoloration. Crowns and roots of symptomatic plants were surface sterilized in 1% sodium hypochlorite for 2 min, rinsed in sterile distilled water for 2 m
