Influence of Soil Moisture on Longevity of Cotton Root-rot Sclerotia »

The fungus Phymatotrichum omnivorum (Shear) Duggar, the cause of cotton root rot, has three known stages in its life history, namely, (i) a vegetative or Ozonium stage (^),^ (2) a conidial or Phymatotrichum stage {!), and {S) a sclerotial stage (4). Several investigators have shown that the sclerotia, or hold-over bodies, are usually present in the soil wherever the disease is found, and play a...

Effects of Soil Oxygen Conditions and Soil pH on Remediation of DDT-contaminated Soil by Laccase from White Rot Fungi

High residues of DDT in agricultural soils are of concern because they present serious threats to food security and human health. This article focuses on remediation of DDT-contaminated soil using laccase under different soil oxygen and soil pH conditions. The laboratory experiment results showed significant effects of soil oxygen conditions and soil pH on remediation of DDT-contaminated soil b...

Root Rot of Pea Caused by Aphanomyces euteiches

Aphanomyces root rot, caused by the oomycete Aphanomyces euteiches, is the most important and destructive disease of pea. Since the inoculum is persistent in the soil, and no resistant cultivars or means of chemical control are available, the disease is difficult to manage. The occurrence of soil suppressiveness against the disease was previously reported, and the main aim of this study was to ...

Biological Removal of Dibenzothiophene from Soil and Changes to soil Sulfate by White-Rot Fungus Phanerochaete chrysosporium

This study investigated biodegradation of dibenzothiophene (DBT) in marsh soil spiked bywhite-rot fungus Phanerochaete chrysosporium. Soil samples were spiked with 100 ppm DBTand incubated at 30°C in a dark chamber for 30 days. Samples were evaluated for pH, Mnperoxidaseactivity, sulfate ion concentration and growth during the tests. Results showedmaximum levels of pH, Mn-peroxidase and sulfate...
