Groundnut is an important oil seed crop for domestic markets as well as for foreign trade in several developing and developed countries. However, its production is limited by Aspergillus species, which cause quantitative losses and generate highly toxic and carcinogenic chemical substances called aflatoxins. To minimize the risk of aflatoxin contamination in groundnut investigated to determine the efficacy of 19 fungicides, 7 botanicals and 7 biocontrol agents. The fungicides, Azoxystrobin + Tebuconazole, Fluopicolide + Propamocarb hcl, Propiconazole and Azoxystrobin showed 100% inhibition of the fungus Aspergillus flavus (OK606055) over the control @500ppm, 1000ppm and 1500 ppm concentration. Among botanicals Neem leaf extract@ 5000, 10000 ppm concentration maximum reduced the growth of test pathogen with 50.59%, 100% growth inhibition compared with control. Among 7 biocontrol agents tested Trichoderma viride isolate 4 recorded maximum growth inhibition (79.17%) followed by Trichoderma viride isolate 2 (78.08%) and Trichoderma viride isolate 1 (76.53%) against Aspergillus flavus (OK606055).

Aspergillus flavus, Azoxystrobin, fungicides, botanicals

The following conclusions are being taken as a result of the findings from the investigation on the treatment of Aspergillus flavus. All of the in vitro tested test fungicides, botanicals, and biocontrol agents were fungistatic and antifungal to the test pathogens. However, it was discovered that fungicides like Azoxystrobin, Tebuconazole, and Propiconazole, as well as combination fungicides like Fluopicolide and Propamocarb hcl, were more effective against Aspergillus flavus.
