Three Fresno State Plant Science students claimed top honors at the California Weed Science Society Conference in Santa Barbara on Jan. 21. Senior Sarah Parry of Sonora and graduate student Elizabeth Mosqueda of Soledad placed second and third, respectively, in oral presentation. Senior Mala To of Cambodia placed third in the poster category. Parry’s organic lettuce project focused on weed-free periods, economics and harvest yields. Mosqueda’s project compared automated- and hand-thinning lettuce methods. To’s project centered on the effect of light intensity on herbicides for hairy fleabane weeds. They work on Fresno State Plant Science professor Dr. Anil Shrestha’s research team. Shrestha also made presentations on vineyard weed management and weed populations in cotton-tomato crop rotations. Alumnus Marcelo Moretti of Brazil, a former Fresno State Dean’s Medalist who is currently a doctoral student at UC Davis, won first-place for his poster presenting Glyphosate and Paraquat herbicide resistance in hairy fleabane and horseweed.
