Dr. Reddy's research is focused on developing effective and sustainable weed control systems for soybean, cotton, and corn. The areas of research include conservation tillage, cover crops, narrow row spacing, crop rotations, and herbicide-resistant crops. Shifts in weed species and populations as a consequence of changes in production practices and weed management systems are evaluated. Long-term impact of these production practices and weed management systems on soil properties, microbial ecology, and plant pathogens are being investigated in collaboration with other scientist.
Biochemical basis for glyphosate injury in glyphosate-resistant soybean and corn is being explored. Redvine and trumpetcreeper are difficult to control perennial vines with extensive deep root systems. Seed dormancy, germination, and emergence, propagule production from rootstocks, leaf surface characteristics, and uptake and translocation of herbicides in redvine and trumpetcreeper are currently being investigated. Redvine and trumpetcreeper response to glyphosate, glyphosate mixtures with other herbicides and adjuvant, and subsoil tillage are being examined to devise control strategies.
Dr. Reddy has authored and co-authored over 100 research articles, reviews, and book chapters, and over 120 abstracts, on herbicide uptake and translocation, QSAR modeling, herbicide interaction in soils, herbicide foliar wash off, and weed biology and control.
