A total of 231 different soil Streptomyces isolates were recovered from 16 different locations in North Jordan. They were assessed for their phytotoxic activity on seeds of cucumber (Cucumis sativus L.) and ryegrass (Lolium perenne L.) placed adjacent to a 2 cm wide Streptomyces culture strips grown at 28C degrees for 3 weeks on starch casein nitrate (SCN) agar. Phytotoxicity was ascertained on...

Subterranean clover (Trifolium subterraneum) is a critical pasture legume in Mediterranean regions of southern Australia and elsewhere, including Mediterranean-type climatic regions in Africa, Asia, Australia, Europe, North America, and South America. Pythium damping-off and root disease caused by Pythium irregulare is a significant threat to subterranean clover in Australia and a study was con...

biological control of sugar beet damping-off of rhizoctonia solani ag-4 by two native streptomyces isolates (s2 and c) was evaluated in green house and field conditions. in dual culture, two streptomyces isolates inhibited mycelial growth of r. solani ag-4. besides, volatile components of s2 and c inhibited r. solani mycelial growth for 72 and 74 percentages, respectively. soil treatment either...

Pythium myriotylum is a notorious soil-borne oomycete that causes post-emergence damping-off in chili pepper. Of various disease management strategies, utilization of plant growth promoting rhizobacteria (PGPR) suppression and promotion an interesting strategy. The present study was performed to isolate characterize PGPR indigenous the rhizosphere Pakistan, test potential suppress chili. Out to...

phosphorus is an essential element for plants. much of the agricultural lands of iran has calcareous soils, in which, due to high ph, phosphorous availability is less, therefore, it appears as a limiting factor for plant growth. application of biofertilizers instead of chemical ones has gained attention in order to produce healthy crops, reduce pollution of soil and water resources by reducing ...

Fungi and fungal community play important roles in the soil ecosystem, and the diversity of fungal community could act as natural antagonists of various plant pathogens. Biological control is a promising method to protect plants as chemical pesticides may cause environment pollution. Pseudomonas fluorescens 2P24 had strong inhibitory on Rastonia solanacearum, Fusarium oxysporum and Rhizoctonia ...

biological control of some plant diseases caused by rhizoctonia solani has been considered as an alternative to chemicals control. rhizobacterium burkholderia cepacia is of current interest as a successful biocontrol agent, and registered as a microbial pesticide by us environmental protection agency. several research works have suggested that nitrogen fixing is also a common feature of most st...
