Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...

Experiments were conducted to determine the settling behavior, survival, and reproduction of the beet leafhopper, Circulifer tenellus (Baker), when maintained on selected host plants. This leafhopper was recently identified in the Columbia Basin of Washington and Oregon as the probable vector of the beet leafhopper-transmitted virescence agent phytoplasma, causal agent of several vegetable crop...

OBJECTIVES This study aimed to investigate the profile of sensitization to silkworm moth (Bombyx mori) and other 9 common inhalant allergens among patients with allergic diseases in southern China. METHODS A total of 175 patients were tested for serum sIgE against silkworm moth in addition to combinations of other allergens: Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tro...

Sugarbeet and fodder beet (Beta vulgaris L.) are being considered for fuel alcohol product ion (1,2). Sugarbeet is susceptible to Heterodera schachtii Schm., and yields are adversely affected (3). T h e effect of the nematode on fodder beet is not known. T h e objective of this study, therefore, was to compare certain aspects of the host-parasite relations of H. schachtii on sugarbeet and fodde...

The structure and function of the plant microbiome is driven by plant species and prevailing environmental conditions. Effectuated by breeding efforts, modern crops diverge genetically and phenotypically from their wild relatives but little is known about consequences for the associated microbiota. Therefore, we studied bacterial rhizosphere communities associated with the wild beet B. vulgaris...

BACKGROUND Intermediates from processing sugar beets are considered an attractive feedstock for ethanol fermentation due to their high fermentable sugar content. In particular, medium prepared from raw sugar beet juice seems to be suitable for use in fermentation processes, but it is microbiologically unstable and requires sterilization. RESULTS This study investigates the effect of ozone tre...

Emamectin benzoate (MK-0244) is a novel semi-synthetic derivative of the natural product abamectin in the avermectin family of 16-membered macrocylic lactones. This epi-methyl amino derivative has unprecedented potency against a broad spectrum of lepidopterous pests with LC90values ranging between 0.001–0.02 ug/ml in ingestion-based foliar spray assays. Emamectin benzoate is ca. 1,500-fold more...

The origin and insecticide resistance status of Diamondback moth (Plutella xylostella) populations infesting canola, vegetables, forage brassicas and weeds has fundamental implications for management of the pest in Australia. Diamondback moth is considered a migratory species in the Northern Hemisphere, but although there is evidence that Diamondback moth moves en-masse throughout Australia in ...

The gypsy moth-Lymantria dispar (Linnaeus)-is a worldwide forest defoliator and is of two types: the European gypsy moth and the Asian gypsy moth. Because of multiple invasions of the Asian gypsy moth, the North American Plant Protection Organization officially approved Regional Standards for Phytosanitary Measures No. 33. Accordingly, special quarantine measures have been implemented for 30 sp...

Two new species of Didicrum from Argentina are described and illustrated: Didicrum naimae and Didicrum letitiae, based on male and female specimens. Specimens were collected with Malaise traps located in Nahuel Huapi National Park, Patagonian region. Including the two new species of Didicrum, twelve are described from South America.
