Article Synopsis
- The study examined how corn and soybean may influence disease dynamics and management due to the presence of a certain pathogen, analyzing root colonization under various tillage and residue conditions.
- Experiments were conducted from 2016 to 2018 across multiple states in the U.S. and Canada, measuring DNA levels from sampled roots to track colonization patterns over time.
- Results showed inconsistent impacts of tillage practices on root colonization and symptom development of sudden death syndrome (SDS), with corn residue occasionally increasing SDS symptoms but not in every instance, suggesting environmental factors play a significant role.
Soybean () sudden death syndrome (SDS), caused by , is a key limitation in reaching soybean yield potential, stemming from incomplete disease management through cultural practices and partial host resistance. A fungicidal seed treatment was released in 2014 with the active ingredient fluopyram and was the first chemical management strategy to reduce soybean yield loss stemming from SDS. Although farm level studies have found fluopyram profitable, we were curious to discover whether fluopyram would be beneficial nationally if targeted to soybean fields at risk for SDS yield loss.

However, DNA interactions with unique surface capping agents have not been fully defined. Using dextrin-capped AuNPs (d-AuNPs), we have developed a novel unamplified genomic DNA (gDNA) nanosensor, exploiting dispersion and aggregation characteristics of d-AuNPs, in the presence of gDNA, for sequence-specific detection.
