Fungicide Cost Reduction with Soybean Rust-Resistant Cultivars in Paraguay: A Supply and Demand Approach

Soybean rust (SBR) is one of the most serious diseases for Paraguay’s economy. To avoid excessive financial losses due to SBR, farmers utilize fungicides. Increasing fungicide costs are, therefore, becoming a threat farmers’ incomes. Developing SBR-resistant cultivars possible solution this problem. investigate effects on soybean in Paraguay, we constructed model supply and demand soybeans considering yields, cultivated area, changes stock quantity soybeans, exports products, feed cake price linkage functions. We established three scenarios: an SBR pandemic which fungicides become ineffective (Scenario 1) adoption 33% (Scenarios 2) 75% 3) areas. The estimation these scenarios demonstrates that cultivar will significantly reduce current by 112–253 million United States dollars (USD). potential benefits widespread dissemination are also considered terms economic disparities environmental risks. establish more sustainable agricultural industry, earlier such required.
