“…All the treatments showed significantly better foliage controlled as well as tuber yield over non-treated control. The results of this study were consistent with previous studies and indicated that the application of protective fungicides could reduce foliar late blight to acceptable levels [7,13,14]. The experiment conducted by Dhanbir et al [15] also similar to the present findings who concluded that all of the treatments reduced the disease but 8% metalaxyl + 64% mancozed ( as Ridomil MZ 72WP) was the most effective.…”

“…Partial budgeting using marginal rate of return is simple to determine profitability of new technology or combination of practices using additional costs and returns which could be easily understood by farmers (CIMMYT, 1998). The method has been used by several scientists including Kassa andBayene (2001), Carroll et al (2009), and Kumar et al (2015).…”

Fungicides overuse in management of late blight has led to increased cost of production and biodiversity issues. To better understand costs and benefits associated with seed treatment to reduce fungicide application, apical cutting and tuber seed crop were pre-treated by either peridermal injection or dipping using T. asperellum suspension at 33%, 66% and 100% concentration and then sprayed separately with Ridomil® (Metalaxyl 4% + Mancozeb 64%) at 21, 14 and 7 (Manufacturer’s Recommended Regime) days interval. Results showed that apical cuttings had 7.5% higher disease severity and 0.2% lower yield than crop from seed tuber. Untreated and 33% T. asperellum were not significant different (p = 0.05) in disease and yield scores. T. asperellum concentration at 66% and 100% reduced disease severity by 26% and 27% resulting to 30% and 29% yield increment respectively. Spray interval of 14 days did not differ significantly from 7 day spray interval in terms of disease score and yield but the regime MRR% was double 7 day spray interval. Maximum yield loss was observed in unprotected plots followed by treatments sprayed at 21 days interval. Combination of 66% and 100% T. asperellum concentration with 14 days interval resulted to higher yield and marginal rate of return compared to any other combination. Seed dipping was four times profitable than injection. The findings suggest that seed treatment at 66% and 100% T. asperellum concentration by dipping in combination with Ridomil® application at 14 days interval significantly reduced late blight epidemics and improved on yield and consequently increased net farm income.
