An isolate of the nematode-trapping fungus Monacrosporium drechsleri was collected from cultures of the root-knot nematode Meloidogyne arenaria that had been maintained on tomato roots in greenhouse pots in Beltsville, Maryland. The plant-parasitic nematodes Heterodera glycines, Meloidogyne incognita and Pratylenchus zeae and the free-living nematodes Caenorhabditis elegans and Panagrellus redi...

many fungi cause sugar beet root rot during various stages of the plant growth. among them rhizoctonia spp. induce crown rot, dry rot and violet root rot on sugar beet (whitney and duffos,1986). root rot caused by phytophthora drechsleri has been observed in fields with excessive moisture (habibi,1975). pythium aphanidermatum has been recognized as one of the causal agents of sugar beet, dampin...

in vitro studies with trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. microscopic observations showed that t. harzianm and t. viride, isolated from soil samples from ahwaz and karaj, adversely affected the mycelial ...

in order to study the role of phytophthora species associated with greenhouse cucumber root and crown rot, diseased sampled were collected in southern kohgiluyeh and boyerahmad province. pieces of infected root and crown of cucumber were washed with tap water blotted dry and plated on cma supplemented with delvocid (10 ppm pimarcin), ampicillin (250 ppm), rifampicin (10 ppm) and pcnb (150 ppm)....

Background: Phytophthora blight (PB), caused by drechsleri f. sp. cajani, is soil borne disease of pigeonpea (Cajanus cajan L.). The use plant growth promoting rhizobacteria (PGPR) in agriculture leads to alternative management crop a sustainable ecofriendly way. Methods: In vitro and vivo experimentation was conducted at fields Punjab Agricultural University, Ludhiana during kharif season 2017...
