TriCal, Inc. is proud to congratulate Nabin Poudel of the University of Georgia and Shiv Singla of the University of Delaware, the two recipients of the 2026 Storkan-Hanes-McCaslin Research Foundation Award.
Their research focuses on two important challenges in crop production:
Nabin Poudel is studying resistance to Meloidogyne incognita in squash, with the goal of identifying resistance that could support future breeding and nematode management strategies.
Shiv Singla is researching how mustard-derived glucosinolates and isothiocyanates can help suppress Phytophthora capsici, with the goal of improving the effectiveness and predictability of biofumigation.
Both projects address challenges that growers face in the field and highlight the importance of research in developing new and sustainable crop protection tools.
Since 1988, the Storkan-Hanes-McCaslin Research Foundation has awarded $702,500 to 99 students, providing annual support for research addressing important challenges in agriculture.
Congratulations to Nabin and Shiv on this well-deserved recognition!

New research from TriCal, Inc. is helping answer one of the biggest questions in Sweetpotato production: Can soil fumigation effectively manage root-knot nematodes while preserving soil health?
Our latest field trials near Atwater and Turlock, California, explored the impact of soil fumigation on nematode suppression, soil microbiome stability, and crop performance. The early results offer encouraging insights for growers focused on protecting yields while supporting long-term soil productivity.
Trical analyzes crop, target pests, soil conditions, weather, irrigation, and past treatments, among many other variables. Using our years of knowledge, first-hand experience, and ongoing R&D, we put together a recommended treatment plan. We walk our customers through the regulatory requirements and are on-hand to ensure a safe and successful application. We follow up to make sure our customers are satisfied with the results.

This potato grown in untreated soil shows symptoms of common scab, a soilborne disease that can impact tuber quality and marketability. Common scab can significantly reduce the value of a crop due to its appearance.
An integrated management plan, including soil fumigation where appropriate, can help reduce disease pressure and create a healthier growing environment for your potato crop. Every field is different, which is why selecting the right strategy starts with understanding your soil and production goals.
TriCal, works with growers to develop customized soil health solutions that support strong crop performance from the ground up.
