true myrtle, myrtus communis l belonging to myrtaceae family is an important medicinal herb in traditional medicine and pharmaceutical industries in iran. moreover because of  being evergreen, having dense foliage and ease of pruning, it is planted at steep slopes, grasslands, boulevards and sidelines of parks as an ornamental shrub or hedge of green. it is distributed in southern europe, asia,...

The southern root-knot nematode, Meloidogyne incognita, is the most damaging pathogen of cotton in the USA. Host-plant resistance to root-knot nematodes is an effective means of reducing crop losses and reducing nematode population levels in a field. Resistance to plantparasitic nematodes refers to the suppressive effect of the plant on the nematode’s ability to reproduce; tolerance describes t...

Multiple Brassica species commonly grown in Georgia were evaluated as a potential alternative to methyl bromide for management of root-knot nematode in vegetables. Brassica species produce general biocides called glucosinolates and were grown as cover crops and incorporated as green manures prior to transplanting of vegetable crop. Nematicidal activity of the Brassica species was based on net c...

The incorporation of a rye (Secale cereale L.) cover crop into the soil prior to planting cotton (Gossypium hirsutum L.) has been shown to restrict damage caused by root-knot nematodes (Meloidogyne incognita (Kofoid and White) Chitwood). A greenhouse study was conducted to determine the duration of the effectiveness of rye decomposition in controlling root-knot nematode damage in relation to th...

Some 340 isolates belonging to Mucorales, obtained from rhizosphere of root knot nematode host plants in ChaharMahal & BakhtiariProvince, were studied during 2003-5. Fourteen new taxa, namely, Absidia spinosa, Actinomucor elegans, Cunninghamella echinulata var. echinulata, C. echinulata var. nodosa, C. echinulata var. verticillata, Mucor circinelloides f. circinelloides, M. circinelloides f. lu...

The biological control efficacy of a greenhouse soil bacterial mixture of Lactobacillus farraginis, Bacillus cereus, and Bacillus thuringiensis strains with antinematode activity was evaluated against the root-knot nematode Meloidogyne incognita. Two control groups planted in soil drenched with sterile distilled water or treated with the broadspectrum carbamate pesticide carbofuran were used fo...

root-knot nemaode which causes extensive damage to legumes and cerealshas beenreported in many countries. the nematods has been observed on legumes, roots in manyregions of the world, causing swollen root and yield reduction. in order to evaluate the effect ofirrigation interval on reproductive traits of root-knot nematode, and the damage inflicteduponnavy bean, a study was conducted in 2011 in...

In the Pacific Northwest, alfalfa (Medicago sativa) is host to two species of root-knot nematodes, including race 2 of the Columbia root-knot nematode (Meloidogyne chitwoodi) and the northern root-knot nematode (Meloidogyne hapla). In addition to the damage caused to alfalfa itself by M. hapla, alfalfa's host status to both species leaves large numbers of nematodes available to damage rotation ...

A strain of the fungus Fusarium equiseti isolated from soybean cyst nematode secretes nematode-antagonistic compounds. Bioassay-guided fractionation of an extract of the culture broth was undertaken to identify the compounds. Fractions were assayed for activity against a root-knot nematode (Meloidogyne incognita), a plant pathogen that attacks the roots of numerous plant species. Two trichothec...
