Abstract
Objective of study was to optimise the dose of EC37, EC39 and EC 40 against Colletotrichum coccodes in tomato fruit by response surface methodology. In the in-vitro assay, three products were tested against C. coccodes by minimum inhibition concentration, then by using model to test the effects of three levels of two factors (concentration and treatment time) for post-harvest treatment of tomato fruits. The results indicated that 0.55% product concentration with 15 min exposure time was the effective optimised dose treatment with least fruit rot spoilage with retention of fruit texture and colour during storage, on par with the positive control (0.1% Difenoconazole). Storage studies (28 ± 2 °C, 70 ± 5% RH) with above optimised dosage of these product treatments showed less anthracnose incidence, better retention of fruit quality of treated tomato fruits as compared with the positive control and the control fruits after 12 days of storage.
