Rationale Take-all patch, caused by Gaeumannomyces graminis f. sp. avenae, is favored by alkaline soils. Because the calcareous sands used for putting greens in the Midwest have a high pH, bentgrass greens constructed with high sand content or to USGA specifications are especially prone to the disease. Previous research addressed take-all patch on established bentgrass greens and fairways with ...

abstract the role of fluorescent pseudomonads in biocontrol of take-all disease caused by gaeumannomyces graminis var.tritici (ggt) has been the subject of many researchs in the recent years. biofilm formation in fluorescent pseudomonads play an important role in biocontrol disease. for this purpose,130 strains of fluorescent pseudomonads isolated from wheat rhizosphere in different regions of ...

The hypersensitive reaction in incompatible wheat-rust interactions is characterized by an increase in lipoxygenase activity detectable as early as 28 h after penetration o f the pathogen. In contrast, lipoxygenase activity in the compatible interaction did not increase until the onset of sporulation. Lipoxygenase activity also increased following treatment o f wheat leaves with an elicitor fra...
