Book Description
Master's Thesis from the year 2004 in the subject Biology - Parasitology, grade: First, Tamil Nadu Agricultural University, course: Plant Nematology, language: English, abstract: Nematodes are tiny, microscopic round worms which are subterranean in nature and affect almost all the agricultural crops and cause substantial yield loss to the farmers. Nematode management over years relied on chemical methods. Owing to the ill effects with the application of chemicals, ecofriendly methods are gaining importance now a days in nematode management. Marigold is an effective antagonistic plant against nematodes. The plant, by the production of alpha terthienyl bithenyl compounds from its roots, repel the nematodes and reduce its population. Understanding the mechanism involved in the antagonistic nature of the plants will result in the better enhancement of the nematode management practices in an environmental friendly approach. Tomato (Lycopersicon esculentum Mill.) is the most important solanaceous vegetable. In India, it is produced around 1, 75, 00,000 MT/ha. Lycopene, an antioxidant is the primary product of tomato, which gives colour to the fruit and protects humans against cancer and heart diseases. Moreover the fruit is also rich in Vitamin A and C. Among the yield reducing factors in tomato, root knot nematode, Meloidogyne incognita is the only species known to cause economic damage and often happens to be the major limiting factor in the successful cultivation of tomato (Lycopersicon esculentum Mill.) In affected roots, the functional root system gets modified to galls and it impairs the uptake of water and nutrients. Poor development of root system makes the plant highly susceptible to drought. The entire root system may be shallow with excessive branching.

Book Description
Root-knot nematodes constitute a major constraint to agricultural production worldwide. They are particularly devastating in the vegetable industry in the tropical world. Management strategies such as cultural, biological, physical and host resistance have peculiar limitations. Chemical control however is most effective, but the effect of synthetic pesticides on the environment raises serious ecological concerns. Active ingredients identified in the African marigold have nematicidal properties and highly lethal to root-knot nematodes. In this study, the effective stage of the African marigold in managing root-knot nematodes was investigated in plant house, laboratory and micro plots experiments. In all cases, the effective stage of the antagonistic plant corresponded to 8-11weeks of growth during which period population reduction was maximum, hatching inhibition was greatest and root gall index was lowest. This information is useful for integrated pest management (IPM) formulation and implementation. Agricultural researchers, extension agents, students and farmers would find this book most useful.

Book Description
Nematodes are microscopic, eel-like roundworms that can infect humans, animals, and plants and cause serious damage and yield losses in a wide range of crops worldwide. This book includes thirteen chapters that address such topics as diagnosing nematode infections in crops (fruits and horticultural crops), management and biological control of plant-parasitic nematodes, biological indicators of nematodes, and entomopathogenic and marine nematodes. This comprehensive volume is a useful resource for students, teachers, researchers, field workers, and all those interested in and working with nematodes.
