Importance of Plant Parasitic Nematodes in Colorado Crops
Nematodes are worm-shaped nearly microscopic animals, many of which are virtually invisible to the unaided eye when they are in the soil or within plant material. Of the known nematode species, approximately 50%, 25%, 15%, and 10% are free-living, marine, animal parasites, and plant parasitic nematodes (PPNs), respectively. Freeliving nematodes are very important in maintaining the soil bio-dyn...
متن کاملIncidence and Population Density of Plant-Parasitic Nematodes Infecting Vegetable Crops and Associated Yield Losses in Punjab, Pakistan
Plant-parasitic nematode population densities were determined from 325 root and soil samples collected from vegetable growing areas in Pakistan. Yield losses associated with nematode presence were quantified on 19 vegetable crops during 2007 and 2009. The most abundant plant-parasitic nematodes detected, in order of decreasing frequency of infestation (percentage of samples), were Meloidogyne i...

the number of bacteria per dauerjuvenile. Preliminary data established similar LD50s and LT50s for X. nematophilus subsp, nematophilus (from the DD 136 strain) and X. nematophilus subsp, nematophilus vat. mexicanus (from the Mexican strain). The absence of toxin production by either S.feltiae strain or bacterial types in a culture medium similar to the host's hemolymph has been reported (5,6). ...
متن کاملSelecting cover crops for sites infested with plant-parasitic nematodes in Michigan
Cover crops are often defined as crops grown for the protection and enrichment of the soil. They are sometimes referred to as green manures or living mulches because if the definition is expanded a bit they are crops grown to suppress weeds, build productive soils and help control pests and diseases. Cover crops can be soil builders, soil looseners, soil water conservers, erosion fighters, nutr...
متن کاملThe Effect of Green Manure Crops on Plant Parasitic Nematodes in the South African Sugar Industry
Plant parasitic nematodes, Meloidogyne javanica in particular, cause significant yield losses in sugarcane crops in South Africa. The chemicals at present available for nematode control are expensive and potentially detrimental to the environment. It has been reported that various types of crops reduce the numbers of plant parasitic nematodes. Seven green manure crops (sunn hemp, marigold, oats...
