Field experiments were conducted for control of the southern root-knot nematode (Meloidogyne incognita) and cotton seedling disease fungi (primarily Thielaviopsis basicola) in one naturally infested field during 1999 and 2000 and in three additional fields in 2000. Treatments included: seed-applied fungicides (triadimenol + mefenoxam + thiram and carboxin + PCNB + mefenoxam), cultivars (Paymast...

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 ...

During a compatible interaction, root-knot nematodes (Meloidogyne spp.) induce the redifferentiation of root cells into multinucleate nematode feeding cells (giant cells). Hyperplasia and hypertrophy of the surrounding cells leads to the formation of a root gall. We investigated the plant response to root-knot nematodes by carrying out a global analysis of gene expression during gall formation ...

Isfahan Agriculture Research Center, I.R. Iran * Corresponding author’s e-mail: [email protected] Abstract The survey conducted to assess the incidence of root-knot disease on tomato in 8 localities in and around Aligarh (India) showed that the crops of tomato in all the 8 localities were infected with root-knot nematodes. Highest frequency (90%) was found in Idgah area, closely followe...

in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

The prevention and control of root-knot nematode disease is a worldwide challenge there are not many varieties pesticides for control. To meet the huge market demand, development new nematicides urgently needed. lethal effects soil fumigant dimethyl disulfide (DMDS) mixed with chemical compounds copper sulfate (CuSO4) ammonium bicarbonate (NH4HCO3) on Meloidogyne incognita were tested using imm...

Root-knot nematodes represent one of the most important plant pathogens in Pomegranate cultivation regions. By studying structure plant-parasitic community inhabiting rhizosphere fields, it was found that
