 My name is Steve Lee. I'm the extension weed scientist and associate professor in the department of crops or environmental science in college agriculture of Harvard University. So my program mainly works in herbicide evaluation, weed control with integrated approaches, and also we evaluate drones, remote sensing, precision spraying a lot these days for crop protection and crop management. So we reach our audience in multiple ways. Usually we have over thousands of people in our in-person meetings and trainings. So in-person interaction is very important for the program. At the same time, we also utilize internet-based methods to reach our clients, social media, newsletters. So my program mainly runs field research. It's very applied and we conduct research every year at multiple locations throughout the state. But all the information we promote in our extension programs are research or science based. If we do not evaluate certain products or practice for multiple years at multiple locations, I do not feel like we have enough confidence to promote this information. So we try to achieve great weed control with herbicides, cover crop and alternative approaches which are sustainable and environmental friendly. At the same time, we want to utilize the new technologies and precision tools to manage a common past in row crops better and also spray chemicals or pesticides with more precision.
