Recent research has demonstrated an important interaction between Thielaviopsis basicola, the cause of black root rot, and the root-knot nematode, Meloidogyne incognita (Walker et al., 1998; 1999; 2000). This interaction causes dramatic reductions in early-season growth in producers’ fields and yield reductions of 21 to 44% have been documented in microplot and field research. The interaction i...

wheat root and crown rot known as take-all disease caused by gaeumannomyces graminis var. tritici is one of the most important diseases of wheat worldwide. in iran,the disease has been reported from provinces such as markazi and golestan. in recent years, symptoms of the disease such as stunted and yellow plant, rotted roots and whitened/empty heads have been observed in wheat fields in various...

Rhizo-bacteria of high biocontrol potential against different Fusarium isolates were bio-assayed under both laboratory and greenhouse conditions. Eighty five rhizo-bacteria isolated from the rhizosphere of plants growing in various desert areas were screened for their antagonistic activity against eight Fusarium isolates (four isolates of Fusarium solani and four isolates of Fusarium oxysporum)...

Paulownia species are fast growing trees native to China, which being grown in managed plantings several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, collapse, as a consequence root crown rot, were observed around 40% 2-year-old planting elongata × P. fortunei Calabria (Southern Italy). Two Phytophthora consistently recovered from root...

ABSTRACT The induction of disease-suppressive soils in response to specific cropping sequences has been demonstrated for numerous plant-pathogen systems. The role of host genotype in elicitation of the essential transformations in soil microbial community structure that lead to disease suppression has not been fully recognized. Apple orchard soils were planted with three successive 28-day cycle...
