Hardcover. Zustand: New. The interest in the use of entomopathogenic nematodes as biological pest control agents has increased exponentially over the past decades. A hundred different laboratories explore these nematodes and their bacterial symbionts in more than 60 countries from every inhabited continent. Despite research breadth that extends from molecular biology to field ecology, the discipline is unified by common interest in biological control. Thirty years ago, the idea of using nematodes to control pest populations was vague promise held by the handful of researchers working with these obscure insect parasites. Today, they are no longer a laboratory curiosity but have begun to gain acceptance as environmentally benign alternatives to chemical insecticides. The entomopathogenic nematodes have proven particularly successful and are now commercially mass-produced in six of the seven continents to treat pest problems in agriculture, horticulture and human husbandry. The ease of mass production and exemption from registration requirements are the two major reasons for early interest in the commercial developments of entomopathogenic nematodes. However, demonstrations of practical use, particularly in Europe and North America and subsequently in Japan, China and Australia, spurred developments across the world that have led to the availability of nematodes against pests that were once thought impossible to control.

Taschenbuch. Zustand: Neu. Neuware -Sugar-beet (Beta vulgaris L.) is considered an important root crop, which is ranked second to sugar-cane for supporting the expansion of Egyptian sugar industry. Root-knot nematodes (RKNs) Meloidogyne spp. are among the most deleterious plant pathogens since these organisms play a detectable role in limiting the productivity of such economic agriculture crop. The root ¿knot nematode Meloidogyne incognita (Kofoid & White) Chitwood is among the most important nematode infecting sugar-beet. Because of the lack of plant resistance to most species of root-knot nematode as well as the environmental restrictions on nematicidal use for controlling plant parasitic nematodes, biological control and other eco-friendly disease control measures have gained recently increasing interest.The activation of the plant's own defense system through biotic and abiotic agents, called elicitors, has been considered as a focus of research only in recent years for the control of plant pathogens. The resulting elevated resistance due to an inducing agent upon infection by a pathogen is called induced systemic resistance (ISR) or systemic acquired resistance (SAR).Books on Demand GmbH, Überseering 33, 22297 Hamburg 168 pp. Englisch.
