CONT

Take-all patch, formerly known as Ophiobolus patch and sometimes called Gaeumannomyces patch, occurs in most cool temperate regions. The disease is often confined to Agrostis spp. growing on poorly drained, wet soils or on soils that have recently been limed heavily, but the pathogen may also affect other turfgrass species. At first, the small, light brown dead patches may resemble those of Gerlachia patch, but take-all patch continues to spread throughout the year...

OBS

The fungus forms dark brown to black ectotrophic runner hyphae on roots, crowns, stolons, and rhizomes of host plants.

OBS

piétin-échaudage du gazon : équivalent fourni par Agriculture Canada (Pesticide Information Call Line). Il s'agit d'une maladie du gazon causée par Ophiobolus graminis var. avenae (Gaeumannomyces graminis var. avenae). Bien que «piétin-échaudage» tout court suffit lorsque la plante hôte est clairement désignée par le contexte, il vaut mieux préciser «du gazon» puisque le piétin-échaudage attaque aussi les céréales (référence : ACTAG-2, 1979, pages 174-183).

Cassava bacterial blight. Infested leaf has angular watersoaked spots along its veins, margin, and tip. The infected leaf blade turns brown with the typical watersoaked symptom at the leading edge of the brown patch. As the disease further develops, the spots join together into large patches killing the leaf blade as they expand. The leaf eventually dries and falls down.

CONT

L'agent causal de la bactériose du manioc est une bactérie que l'on retrouve à l'intérieur des feuilles et des tiges. Symptômes : Au début, les dégâts causés par la bactériose se présentent sous forme de taches nécrosées d'aspect humide (lésions) [...] Ces lésions angulaires se rejoignent et se transforment progressivement en des taches plus grosses qui détruisent le limbe foliaire. Le limbe brunit et porte à l'extrémité antérieure de la tache brune la tache imbibée qui caractérise la bactériose. Ce symptôme est dénommé brûlure foliaire. Les feuilles gravement brûlées flétrissent, meurent et tombent provoquant la défoliation et le «dieback», ou la mort définitive de la pousse.

OBS

La bactériose du manioc ne s'attaque qu'au manioc.
