The Ophioviridae is a family of filamentous plant viruses, with single-stranded negative, and possibly ambisense, RNA genomes of 11.3-12.5 kb divided into 3-4 segments, each encapsidated separately. Virions are naked filamentous nucleocapsids, forming kinked circles of at least two different contour lengths. The sole genus, Ophiovirus, includes seven species. Four ophioviruses are soil-transmit...

Oxyfluorfen is a selective pre and post emergent herbicide used to control certain annual broadleaf and grassy weeds in vegetables, fruits, cotton, ornamentals and on non-crop areas. It is a contact herbicide and light is required for it to affect target plants (USDA 1990). Oxyfluorfen has a strong tendency to adsorb to soil particles. It is therefore, unlikely to leach downward or to, contamin...
