AGRICULTURAL RESEARCH AND GRADUATE EDUCATION
1. Researcher uses automated imaging technology
for fast detection of destructive soybean pest
exander
Lei Zhang, assistant professor of plant nematology, is on the lookout for the
soil-borne roundworm called soybean cyst nematode (SCN). Zhang can¡¯t see the
microscopic parasite with his eyes, but technology available in the Ag Alumni Seed
Phenotyping Facility (AAPF) at Purdue might. With grant support from the Indiana
Soybean Alliance, Zhang and PhD student Vijay Kunwar, collaborating with the AAPF
team and Jianxin Ma, professor of agronomy and Indiana Soybean Alliance Endowed
Chair in Soybean Improvement, are working on developing methods for the early and
fast detection of SCN infection of soybean roots using two advanced imaging
technologies: hyperspectral imaging and chlorophyll fluorescence imaging. The team¡¯s
efforts to find soybean root infections by SCN earlier and faster may help reduce
this parasite¡¯s devastating damage to soybean crops, contributing both to breeding
