Use the Nano-Chitosan to Inhibit the Two Fungi Aspergillus Niger. And Nigrospora Sphaerica Which Isolated From Zea Mays L. Laboratory

The isolation from Zea mays L. showed two types of fungi Aspergillus niger., Nigrospora sphaerica with a frequency of 38% and 22 %sequentially, Fungi were Isolated diagnosed by keys of taxonomic, Diagnosis of the fungus was assured N. sphaerica depending on the Polymerase Chain Reaction Technology {PCR}. It is the first recording in Iraq/ Karbala Province. Nano-chitosan achieved 100% inhibition rates in vitro
