Abstract

     The experiment was carried out in the laboratory of the Biology Department, College of Education/ Sabr - University of Aden – Yemen, during the period May- July 2017. The aim of this study is to find out the effectiveness of four types of aqueous extracts of animal waste, namely cow manure, sheep manure, donkey manure, and poultry blue (10% weight/volume) against Aspergillus niger that causes black rot in onions, Aspergillus flavus  that causes rot in peanuts. There were significant differences between the different treatments, and the effectiveness of poultry glaucoma was the most effective among the different treatments against the fungi A .niger, A .flavus  where the inhibition rate was 70.69, 67.30% over the following. The lowest effectiveness of donkey manure where the inhibition percentage did not exceed 36.53 and 30.81%, respectively.
Accordingly, our results indicate the effectiveness of aqueous extracts of animal waste (cow manure, sheep manure, donkey manure, and poultry glaucoma (10% weight/volume)) against Aspergillus niger that causes black rot in onions, Aspergillus flavus that causes rot in peanuts, but in a similar way. uneven.
