Two experiments were conducted to assess nutrient partitioning in coffee (Coffea arabica cv. Typica land race Guatemala) infected with Meloidogyne konaensis. Nutrient levels were quantified from soil, roots, and leaves. In the first experiment, 500-cm3 aliquants of a Kealakekua Andisol were infested with four initial population densities of M. konaensis ranging from 0 to 1,500 freshly hatched s...

Strategic application of moxidectin pour-on (Cydectin) was evaluated in Uganda for its effect on pasture larval counts and gastrointestinal nematode faecal egg counts in village cattle kept under tethering (semi-intensive) grazing management. The strategic deworming schedule involved treating cattle twice at an interval of 2 months, at the end of the 1st wet season and during the 2nd wet season...

Nematode egg hatch is an important phase in the life cycle (1). Factors that influence this process may have a highly significant effect upon the survival of the nematode, its generation time, and its ability to incite disease. Root diffusates and seasonal changes in environmental, physical, and chemical factors that are related to diapause in unhatched larvae affect the hatching of plant-paras...

Root-knot nematodes (RKN) cause substantial yield decline in eggplant and sustainable management options to minimize crop damage due to nematodes are still limited. A number of genetic engineering strategies have been developed to disrupt the successful plant-nematode interactions. Among them, delivery of proteinase inhibitors from the plant to perturb nematode development and reproduction is a...

Like any other branch of Agricultural Sciences, the Division of Nematology at IARI, initiated researches in the exciting field of biochemistry and molecular biology of plant parasitic nematodes during the early seventies of last century. The main research areas were biochemical mechanism of resistance against phytonematodes and diagnostics of economically important plant parasitic nematodes. Sp...

With a diverse host range, Meloidogyne incognita (root-knot nematode) is listed as one of the most economically important obligate parasites of agriculture. This nematode species establishes permanent feeding sites in plant root systems soon after infestation. A compatible host-nematode interaction triggers a cascade of morphological and physiological process disruptions of the host, leading to...
