The integration of pre-emergence (PRE) herbicides is an important component sustainable long-term weed management programs in soybean [Glycine max (L.) Merr.]. objective this study was to evaluate the efficacy 11 PRE on residual control soybean. Field experiments were conducted 2018 and 2019 at Arlington Lancaster, WI. Herbicide treatments consisted imazethapyr, chlorimuron-ethyl, cloransulam-m...

the distribution of phytophthora parsiana a high-temperature tolerant newly described species was studied in southern iran and examined its host range in woody perennial plant species in greenhouse condition under high inoculum potential. among different plant species examined, almonds were highly susceptible by different isolates. from 24 woody plants inoculated, the disease severity in descen...

bacillary dysentery, or shigellosis, is a disease of humans in which the colonic epithelium is invaded by bacteria and subjected to inflammatory destruction. the aim of this study was to develop a polymerase chain reaction(pcr) test for detection of virulent shigella spp.. for this purpose, the primers were designed to amplify a 526-bp internal region of the shigella spp. icsa gene, which encod...

3450 bovine from different breeds and ages were clinically examined for the presence of arthritis. 120 cases showed macroscopic evidences of arthritis. mycoplasma spp were isolated from synovial fluid of 21 affected animals. in addition to mycoplasma spp. arcanobacterium pyogenes and staphylococcus epidermidis were isolated from 2 cases. the synovial fluid was markedly increased, straw color, t...

Weeds are a major problem in seeding rangeland and cropland to native grasses. However, many immature weedy forbs and grasses are palatable to cattle. Research was conducted using yearling cattle for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedings (1987, 1988) at Mead, Nebraska on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) soil....

the allelopathic potential of the foliage tissues of eight barley cultivars was investigated using seedlings bioassays of indian brown mustard (brassica juncea) and green foxtail (setaria viridis) as typical broadleaf and grass weeds of the croplands. the correlations of allelochemical compounds with seed germination of weeds were determined. the barley cultivars used were jackson, bronco, cdc ...
