Post harvest decay in harvested tomatoes is worldwide major battle. Post harvest decay recognized persistent problem. Many fungicides are available to control rotting but they are injurious to human health. Biological controllers are eco friendly alternative remedies instead of fungicides. Antagonism process of biological control stops sever loses of post harvest tomatoes. For the antagonism effect of isolated healthy tomatoes flora organisms were applied against rotten mould flora isolated from the rotten tomato. In the antagonism study analyzed Lactobacillus sp. against Fusarium sp. (Inhibition zone 18 mm.), Alternaria sp. (Inhibition zone 15 mm.), Rhizopus sp. (Inhibition zone 20 mm), and Penicillium sp. (Inhibition zone 30 mm.). Pseudomonas sp. antagonism against Fusarium sp., Alternaria sp., Rhizopus sp., and Staphylococcus sp. against three moulds were Aspergillus sp., Alternaria sp., and Penicillium sp. Other isolated bacteria shown antagonism against two rotting moulds. Healthy tomato micro flora Rhizopus sp. against four rotting moulds Aspergillus sp., Fusarium sp., Alternaria sp. and Penicillium sp. tested but Fusarium sp., Penicillium sp. against only two and one rotting moulds.
