TAILIEUCHUNG - Impact of pesticides on the diversity of fungi at local shallot in Palu, Indonesia

Intensive pesticide application caused damaged of natural balance in agricultural land. Purpose of the study is to evaluate frequency of pesticides application and their impact presence of fungi at local shallot plants in Oloboju village, Sigi Regency, Central Sulawesi. Almost all of local shallot farmers was used synthetic pesticides controlled pests and diseases with high, medium and low of their frequency applications. By comparing final application of pesticides, the results was showed increasing pesticides application can reduced fungi index diversity in rhizosphere and phylosphere by approximately and , respectively. It compared with frequency of pesticides application in low and medium with a diversity index value about and in rhizosphere, different in phylosphere result at and . The similar application was showed the evenness index and species richness index of rhizosphere and phylosphere. The impact application of pesticides was showed a resistant fungi species such as Fusarium sp. as a pathogenic fungi and found in all of frequencies pesticide application. The presence of Trichoderma spp. and Aspergillus niger as endophytic fungi at all of frequencies pesticide application, giving important information and very useful for this study. Antagonistic fungi and their existence in local shallot field can be developed to be biological agents, because they have survival properties in environments with varying levels of pesticide residues. | Impact of pesticides on the diversity of fungi at local shallot in Palu, Indonesia
