pennisetum stramineum/necrosis

The genus Striga comprises about 30 obligate root-parasitic plants, commonly known as witchweeds. In particular, S. hermonthica, S. asiatica and S. gesnerioides cause immense losses to major stable crops in sub-Saharan Africa. Most Striga species parasitize grass species (Poaceae), but Striga

Sorghum (Sorghum bicolor) line Tx2786 is immune to strains or isolates of sorghum mosaic potyvirus (SrMV strains SCH and SCH) but susceptible to strains of maize dwarf mosaic (MDMV) and sugarcane mosaic (SCMV) potyviruses (1,2). When grown in proximity to sugarcane, Tx2786 was infected with a virus

Wide hybridization is a one of the important techniques in plant breeding. Oat (Avena sativa L.) and pearl millet (Pennisetum glaucum L.) belong to different subfamilies of Poaceae. In generally, such distant relative species show uniparental chromosome elimination after successful fertilization.

Necrosis at the leaf tips and margins of pearl millet (Pennisetum glaucum (L.) R. Br.) was observed in 1995 in a Pseudomonas syringae resistance screening nursery near Bulawayo, Zimbabwe. Straw-colored lesions with a chlorotic edge often extended the leaf length, and were atypical of the round

Pearl millet (Pennisetum glaucum (L.) R. Br.) fields and cultivar trials in Sadoré, Niger, and Samanko, Mali, were surveyed in late August 1999 Most plants were in the late stem elongation to panicle exertion stage Local open-pollinated cultivars, experimental hybrids, and inbreds had disease

Chinch bug, Blissus leucopterus leucopterus (Say) (Heteroptera: Blissidae), is one of the most important insect pests on forage pearl millet, Pennisetum glaucum L. R. Br., production in the southeastern United States. Twenty-nine forage pearl millet genotypes were assessed for chinch bug resistance

Kikuyugrass (Pennisetum clandestinum) is a C4 grass and invasive weed adopted for use as a primary turf species in some golf course fairways and roughs in southern California. In September 2008, a new Rhizoctonia-like fungus was isolated from a diseased kikuyugrass sample received from a golf course

An outbreak of mortality in cattle grazing kikuyu (Pennisetum clandestinum) pastures on a farm in the western Transvaal is described. These pastures had been heavily infested with army worm (Spodoptera exempta) two weeks preceding the onset of deaths. The main symptoms were excessive salivation,

A potyvirus (proposed name of Zea mosaic virus [ZeMV]) isolated from maize in Israel was analyzed by serology, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of capsid proteins, symptomatology, and sequencing. Parts of the nuclear inclusion b, coat protein, and 3' regions were

Center rot of onion is an economically important disease caused by three Pantoea spp.: Pantoea ananatis, P. agglomerans, and P. allii. Symptoms caused by these three species are similar and include white streaking and necrosis of foliage; and, in some cases, the bacterium may enter the bulb, causing
