Abstract Soil amended with rice straw compost significantly reduced sheath blight severity. The disease caused by the fungus Rhizoctonia solani Kühn is a severe disturbance to cultivation in Indonesia. R. soil borne fungi and highly competitive as saprophyte. In mature compost, propagules form of sclerotia germination were suppressed hyperparasites other biological control agents. Compost matur...

Abstract The production of onion waste derived mainly from bulbs affected by fungal diseases, during classification and storage presents an important agro-environmental issue in regions. Composting is environmentally friendly strategy to recycle agricultural produce organic fertilizers. Modifications the microbial community soil can affect ability pathogen propagules survive, germinate infect p...

abstract polymyxa betae is an obligate parasite and has a worldwide distribution. this fungus is a soil-borne root endoparasite in some plant families such as portulaceae, chenopodiaceae and amaranthaceae. this fungus is the vector of many plant viruses such as beet necrotic yellow vein virus (bnyvv) which causes the disease known as rhizomania. bnyvv is the most economical important viral dise...

In the present study, the occurrence and species diversity of insect-associated fungi in soil collected mainly from forest habitats in different regions of China were compared by using the ‘Galleria biat method’. Insect-associated fungi were defined to include known insect pathogenic fungi, opportunistic pathogens and secondary colonizers isolated from the Galleria mellonella bait insect expose...

Abstract Ethanedinitrile is a chemical soil fumigant with promising efficacy against several key pests including weeds, nematodes, and soil-borne pathogens. The of 12 concentrations ethanedinitrile, ranging from 8.7 to 1,751 mg kg − 1 soil, control seeds tubers five weed species ( Cyperus esculentus, C. rotundus, Malva parviflora, Portulaca oleracea , Stellaria media ), two nematode Globodera r...

Soil is a source of primary inoculum for Aspergillus flavus and A. parasiticus, fungi that produce highly carcinogenic aflatoxins in peanuts. Aflatoxigenic fungi commonly invade peanut seeds during maturation, and the highest concentrations of aflatoxins are found in damaged seeds. A laboratory procedure was developed in which viable peanut seeds were wounded and inoculated with field soil cont...

Trichoderma has gained maximum attention as biocontrol agent due to the fact that it is effective against a large number of soil-borne plant pathogenic fungi, suppressive effects on some root nematodes without adversely affecting beneficial microbes like Rhizobium and capable of promoting growth of certain crops. There are two major methods of inoculum production of Trichoderma spp. viz., solid...

Soils in terrestrial ecosystems store more carbon (C) than plants and the atmosphere combined, and ecosystems’ C dynamics are strongly dependent of nitrogen (N) availability. Moreover, plant production in boreal ecosystems is often limited by low N availability, and N retention in soils is a major constraint on N recirculation to plants. Soil fungi strongly influence C and N interactions in bor...
