Root-knot nematodes suppress yields of flue-cured tobacco an estimated 0.1 to 4.8% annually in the southeastern United States, even though nematode management practices have been widely adopted. Although Meloidogyne incognita races 1 and 3 have predominated, M. arenaria, M. javanica, and M. incognita races 2 and 4 are increasingly important. Seventy-five percent of the flue-cured tobacco hectar...
By 2050, Africa's population is projected to exceed 2 billion. Africa will have to increase food production more than 50% in the coming 50 years to meet the nutritional requirements of its growing population. Nowhere is the need to increase agricultural productivity more pertinent than in much of Sub-Saharan Africa, where it is currently static or declining. Optimal pest management will be esse...
one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzanilla, were transplanted to different sets of pots each pot containing 2000g of sterilized sandy loam soil. the experiment was conducted in a completely randomized design of 32 treatments, each in five replications. treatments were comprised of: control, mere nematode, mere fungus, and fungus+nematode. pots were inocul...
the chemical compound dl-?-amino-n-butyric acid (baba) has been introduced as a promoter of induction of resistance in plants against plant pathogens. in this study, promotion of induction of some such defense compounds as peroxidase and polyphenol oxidase enzymes through dl-?-amino-n-butyric acid application against root knot nematode (meloidogyne javanica) was investigated in cucumber. result...
Interpretation of nematode community indices requires a reference to a relatively undisturbed community. Maturity and trophic diversity index values were compared for five pairs of certified organically and conventionally managed soils in the Piedmont region of North Carolina. Available nitrogen (nitrate, ammonium) was estimated at various lag periods relative to times of sampling for nematode ...
Plants are exposed to large number of threats caused by herbivores and pathogens which cause important losses on crops. Plant such as nematodes can severe damage in food security crops worldwide. Chemical pesticides were extendedly used for nematode management. However, due their adverse effects human health the environment, they now facing strong limitations regulatory organisations EFSA (Euro...
Nonchemical methods and strategies for nematode management including cultural methods and engineered measures have been recommended as an alternative to methyl bromide (a major soil fumigant), due to its role in the depletion of the ozone layer. Hence, an international agreement has recently been reached calling for its reduced consumption and complete phasing out. This present research evaluat...
