2018 NCWSS Student Video Contest

Weed science students representing the PAT Lab earned some top honors at the 2018 North Central Weed Science Society Meeting in Milwaukee, WI. 

Jesaelen Gizotti de Moraes, a doctoral student, received second-place in the graduate student research video contest.  Her video describes the OCA 15EC, a professional contact angle measurement and drop shape analysis device. This piece of equipment allows us to perform analysis of contact angle and surface tension of different solutions. Click on photo below to view full video.

Estefania Gomiero Polli, a master student, received first-place for her Extension/education graduate student video titled “Spray Drift of Pesticides.” The video is about spray drift or the movement of pesticide away from the target area to an unintended site. This event can cause problems such as damage to susceptible off-target sites, reduction in the effectiveness of the pesticide, waste of pesticide and money, and environmental contamination. Putting effort to minimize drift is imperative. Strategies used to reduce drift in field applications include checking pesticide label information, sprayer and weather conditions.  Click on photo below to view full video.

2016 North Central Weed Science Society Posters

The NCWSS is a professional group of those interested in weed science from many perspectives. Many members are affiliated with universities or the crop protection industry; others are crop consultants, state or federal agency or private research personnel, extension educators and others. The NCWSS holds an Annual meeting at which papers and posters are presented, including student paper and poster contests. Click on the posters below to view as a pdf file.
