The Mi gene in tomato (Solanum lycopersicum) is a single, dominant resistance (R) gene that confers resistance against several species of insects and root-knot nematodes. This study examined the impact of root-knot nematode infestation and the plant growth and reproduction of near-isogenic tomato cultivars with and without Mi. The objectives of this experiment were to examine the potential fitn...

From an agronomic perspective, the interactions of phytoparasitic nematodes with leguminous crops can be devastating (Barker, 1998). On a cellular and molecular level, the complexities of the interactions of these microscopic worms with legumes are comparable to those of well-known symbionts (Mathesius, 2003). Because of their agricultural importance, the soybean cyst nematode Heterodera glycin...

B-glycosidases have been implicated in plant pathogenesis by numerous authors (6,8,9,10). B-glucosidase from Pratylenchus penetrans was reported to hydrolyse HCN from a cyanogenic glucoside (amygdalin) during pathogenesis of peach roots (7), and the activity of B-glucosidase from preparasitic larvae of Heterodera rostochiensis has been correlated with the ability to parasitize resistant potato ...

to evaluate the effect of metarhizium anisopliae and trichoderma harzianum on root knot nematode (meloidogyne javanica) in tomato, experiments was performed under controlled as well as greenhouse conditions. volatile and non-volatile tests showed that there is no inhibitory effect against every one of each biocontrol agents. on the larval mortality and inhibition of egg hatching, a laboratory t...

○ Background Production of organic ginger Zingiber officinale Roscoe, Japanese variety, is subject to serious economic loss from several soil borne pests. The plant parasitic root-knot nematode (RKN) Meloidogyne incognita is a persistent pest for ginger production in soils worldwide. Pathogenic bacteria Ralstonia solanacearum, which causes “bacterial wilt” of ginger, has become a serious threat...

Pasteuria penetrans is a bacterial parasite of some plant parasite of nematodes whichcan attach to the cuticle of nematode. Differences in attachment of P. penetrans spores to the second stag juvenile (J2) cuticle may provide evidence for nematode cuticle diversity even between different ages of J2s. For investigating this purpose, we studied the effect of different ages of th...

Root-knot nematodes are globally the most aggressive and damaging plant-parasitic nematodes. Chemical nematicides have so far constituted the most efficient control measures against these agricultural pests. Because of their toxicity for the environment and danger for human health, these nematicides have now been banned from use. Consequently, new and more specific control means, safe for the e...

The southern root-knot nematode (Meloidogyne incognita) is a major parasite of cotton in the U.S., and management tactics for this nematode attempt to minimize population levels. We compared three post-harvest practices for their ability to reduce nematode population levels in the field, thereby reducing initial nematode population for the next year's crop. The three practices tested were: 1) c...

The presence of plant-parasitic nematodes causing crop loss every year had been overlooked in the existing fruits, vegetables and flowers cultivation system Bangladesh. Therefore, study was conducted to isolate identify plantparasitic from soil infected plant-parts fruits (banana, orange), (pointed gourd, tomato brinjal) flower (gerbera) districts Jashore, Jhenaidah, Gazipur Sylhet during 2017-...
