Dr. Jerry Green

 

Jerry is President of Green Ways Consulting and an internationally recognized weed and crop science expert.  He worked as a scientist on herbicide discovery and development, genetically modified herbicide traits, resistant weed management, pesticide formulations and adjuvants, safeners, and the optimization of crop protection products. His career began as the first biologist hired to work on sulfonylurea herbicides and soon after made the first public disclosure of the second sulfonylurea herbicide, sulfometuron.  He is probably best known for his interactions with industry, academic, and government officials in the role of biological program leader for adjuvants.  He is often invited to speak at international conferences, has published over 100 papers, introduced 10 commercial products at technical meetings, and is currently a technical advisor on pest management technology to several companies.
