Field pea (Pisum sativum) is an increasingly important legume crop grown around the world, having a total harvested area of 8 million ha and a total production of 16 million tonnes per year [].Currently, Europe secures a pea production share of about 44%, followed by America and Asia. Of the total million tonnes of pulses produced in Europe, field pea accounts for more than 40% of the. Present study was carried out to examine the biological potential of different fungal and bacterial antagonists viz., Trichoderma harzianum, T. reesei, Aspergillus niger and Bacillus subtilis in management of root-rot disease caused by Macrophomina phaseolina and on the growth parameters of mungbean under pot condition. From the results, it was evident that the microbial antagonists.

The aim of this review was to survey all fungal pathologists with an association with the journal Molecular Plant Pathology and ask them to nominate which fungal pathogens they would place in a ‘Top 10’ based on scientific/economic importance. The survey generated votes from the international community, and resulted in the generation of a Top 10 fungal plant pathogen list for Molecular. l Biological control, and l Cultural (agronomic) practices (sowing dates, plant population etc.). In this review, disease management practices to control economically important foliar diseases of food legumes have been discussed (Table 2). Management of viral diseases has been discussed separately under the virus disease control section. 3.

The best method to control ascochyta blights of pea is to reduce the amount of primary inoculum through sanitation, crop-rotation, and altering the sowing date.

Other methods—chemical control, biological control, and development of resistant varieties—may also be used to effectively control ascochyta agents: Ascochyta pinodes, Ascochyta. One success story of biological control against plant diseases concerns the Cryphonectria hypovirus 1 (CHV-1) that hyperparasitizes the fungus Cryphonectria parasitica and reduces its pathogenicity on chestnut trees, resulting in hypovirulent isolates of the fungus (Milgroom and Cortesi, ).Cited by: Chemical and biological control of the fungal footrot pathogens of Pisum sativum L.

Author: Bradshaw-Smith, Robert Paget. ISNI: Awarding Body: Manchester Polytechnic Current Institution: Manchester Metropolitan University Date of Award. In utilizing fungi as biological control agents against insects, the following categories of treatment are recognized: Permanent introduction of a fungus to an area with a host population.

This would involve establishing the fungus species at the site of the host population. The biological control agent Trichoderma viride was compared with chemical treatments for the control of Erysiphe polygoni on pea in Tamil Nadu, India, in and Powdery mildew incidence with the talc-based T.

viride formulation treatment was and % in andrespectively, compared with and % in the control. The pea yield from the T. viride treatment was Cited by: Although the majority of biological control research have been concentrated on soil borne fungal diseases, a number of studies have focused on fungal pathogens causing diseases and disorders in above-ground parts of plants (Kessel et al., ; Khodakaramian et al., ; Kovach et al., ; Milgroom and Cortesi, ; Smith et al., ).

Integrated pest management is a farming practice promotes the use of biological as well as chemical means to improve plant growth and control disease [2].

Fungicides seed treatment is a very common practice recognized as a useful strategy to combat seed-born pathogens and seedling damping-off. Biological control can be defined as the directed and precise management of biological resources, to protect plants against pathogens.

The control of plant diseases by applying biocontrol techniques is a multifaced scientific area of great interest because of the need to reduce chemical inputs to agriculture and significantly enhance global.

During spring growing season, quantitative disease surveys were conducted to identify the fungal disease agents causing root-foot rot and foliar diseases of pea (Pisum sativum L.) plants.

Caused by Ascochyta pinodes in.

Ascochyta blight, an infection caused by a complex of Ascochyta pinodes, Ascochyta pinodella, Ascochyta pisi, and/or Phoma koolunga, is a destructive disease in many field peas (Pisum sativum L.)-growing regions, and it causes significant losses in grain yield.

To understand the composition of fungi associated with this disease in Zhejiang Province, China, a total of 65 single.

Control root tips or fungal spores treated with nuclease alone exhibited normal morphology and growth. Pea (Pisum sativum) root tips incubated with [32 P]dCTP during a 1-h period when no cell death occurs yielded root cap slime containing 32 P-labeled exDNA.

Our results suggest that exDNA is a previously unrecognized component of plant defense.Biological control agents with rhizosphere competence are self-sustaining, growing with the plant roots, and can provide long-term protection.

With further restrictions on chemical fungicides forestry managers lack effective preparations against soil-borne fungal pathogens causing root diseases. Currently, only one biological control agent is.
