Cowpea (Vigna unguiculata L. Walp) is an ancient crop widely known as Lobia, Vegetable crop, Black-eyed peas. used pulse, fodder, vegetable, and green manure crop. It to suffer from many diseases pests. Nematodes cause a severe damage cowpea production leading economic losses. Among the nematodes, root-knot nematodes (Meloidogyne spp.) Farmyard manure, spent mushroom compost, leaf waste of mari...

introduction: root-knot nematodes (meloidogyne spp.) are important plant pathogens that make large damage to the crops. the activity of root-knot nematode and reaction of host plant results in the development of several knots on the root, which interrupts water and food absorption system of the plant. among popular methods for controlling root-knot nematodes are physical methods (soil solarizat...

Cut flower producers currently have limited options for nematode control. Four field trials were conducted in 2006 and 2007 to evaluate Midas® (iodomethane:chloropicrin 50:50) for control of root-knot nematodes (Meloidogyne arenaria) on Celosia argentea var. cristata in a commercial floriculture production field in southeastern Florida. Midas (224 kg/ha) was compared to methyl bromide:chloropic...

The increased concern for environmental and health hazards have called for a reduction in the use of synthetic nematicides for nematode control. Experiments were, therefore, conducted to ascertain the nematicidal potential of castor bean’s crude extract and its five lower concentrations with water as control. In the in vitro studies, crude castor bean aqueous extract and 10, 20, 30 and 40% diff...

Field plots of Tifton loamy sand were treated with phenamiphos for control of root-knot nematodes in a multiple-crop system of turnips, field corn, and southern peas. Preplant applications of phenamiphos protected roots of turnips and corn from damage by root-knot nematodes. Concentrations of phenamiphos at application in the 0-15-cm soil layer were near 6 mug/g on turnips and near 4 mug/g on c...

The polyphagous parthenogenetic root-knot nematodes of the genus Meloidogyne are considered to be the most significant nematode pest in sub-tropical and tropical agriculture. Despite the crucial need for correct diagnosis, identification of these pathogens remains problematic. The traditionally used diagnostic strategies, including morphometrics, host-range tests, biochemical and molecular tech...

Nematodes are commonly referred to as non segmented round worm, thread worms or pin worms. It‟s body is elongated, cylindrical, bilaterally symmetrical and tapering towards both end. It is pseudocoelomate and dioecious with sexual dimorphism. It‟s impact on agriculture by way of inflicting is quite substantial. In the District Bilaspur of Himachal Pradesh, in the present study on nematodes, two...

Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops worldwide, owing to its high nutritive value and diversified use. Plant parasitic nematodes are important pests of tomato and cause huge economic losses (Bird and Kaloshian, 2003). India is the second largest tomato growing country having cultivation area of 8.8 lakh ha with production of 18.23 mmt with productivity 20....

Previous research has shown that population densities of plant-parasitic nematodes are reduced when a legume crop is grown in rotation with sugarcane. However, this effect is only temporary, as nematodes usually return to high densities within 12 months of planting sugarcane. This rapid resurgence suggests that natural enemies that normally keep plant-parasitic nematodes under control in natura...
