Herman Waguespack, Jr.


Herman Waguespack, Jr. is the newest IR-4 Commodity Liaison Committee member. Herman earned a B.S. in Agriculture from Nicholls State University. While at Nicholls, he was president of the NSU Ag Club and served as president of Delta Tau Alpha honorary agriculture fraternity. He was named the outstanding AG graduate of 1981 and was a Nicholls Hall of Fame graduate. Upon graduation he worked as a sugarcane farm manager for Caire and Graugnard and for several years worked as a Farm Bureau insurance agent in St. James Parish, LA. In 1985, he began his career as a sugarcane agronomist for the American Sugar Cane League working with researchers and farmers throughout the state to develop new varieties and test new technology for the advancement of the Louisiana sugarcane industry. In 1996 he completed his studies at LSU and graduated with a master’s degree in agronomy. Since 1985, he has worked with the Louisiana sugarcane variety development team to release 20 new sugarcane varieties for commercial production. Sugarcane is a unique commodity. It’s a tropical crop that has been improved through breeding to withstand the temperate environment in Louisiana. Although LA experiences freezing temperatures every year, growers can still successfully produce a sugarcane crop and supply approximately 20% of the domestic sugar (sucrose) supply. Herman recently became involved in the IR-4 program while working with researchers at LSU and USDA to develop a management strategy for a new weed that has been causing major losses in the sugarcane fields. Working with engineers and farmers, the American Sugarcane League agronomists have also conducted studies to help improve mechanical planting and other important tools for the industry.

His hobbies include hunting, fishing, guitar, woodworking, gardening and anything Cajun (especially the food). He and his wife Lisa enjoy living in Thibodaux, Louisiana.
