Excited to share that I’ve successfully defended my Master’s thesis! I am grateful to my advisor, Dr.
@Maity_Weed, co-advisor Dr. @D_Russell2 and other committee memebers for their guidance, support and encouragement throughout this journey!

Lots of interest in #Convintro following our video posted earlier this year! One recurring question I’ve received from growers and crop advisors is about soybean crop safety.

The active ingredient in Convintro is #diflufenican (Group 12), a phytoene desaturase (PDS) inhibitor that disrupts carotenoid biosynthesis, resulting in bleaching of susceptible plants.

Over the years, our #WiscWeeds research has occasionally documented temporary soybean leaf bleaching (see photo), particularly following heavy rainfall after crop emergence.

The good news? In trials where we observed this early-season injury, we did not detect soybean yield reductions.

Sharing this photo so growers and crop advisors considering Convintro for 2027 are aware of this potential early-season response and aren’t caught by surprise if they observe it in their fields.

Product formulation matters!

Our ongoing #WiscWeeds research, conducted in collaboration with agricultural cooperatives across Wisconsin, shows that several generic #glufosinate products evaluated thus far have underperformed compared to brand-name products, despite equivalent active ingredient rates.

Formulation and built-in adjuvants can make a BIG difference! More research underway. Stay tuned!

⚠️ HPPD resistance is one to watch closely.

These photos from Dr. Luma Loureiro show a #waterhemp (Amaranthus tuberculatus) population confirmed resistant to mesotrione applied POST (left) and PRE (right).

HPPD-inhibitors (Group 27 herbicides) are critical tools in #corn, and their importance will only grow as new #soybean traits expand opportunities for HPPD use.

More use = more selection pressure!

We need to be good stewards of HPPD-inhibitors and protect their utility across cropping systems.

It may sound like common sense to some, but many #glufosinate applications still go out without AMS (ammonium sulfate).

Watch the difference it makes on velvetleaf control ⬇️

An invasive mullein patch spotted in #Yosemite is a reminder of how quickly #invasiveplants can colonize disturbed sites. Even “benign” species can outcompete natives & alter ecosystem function.

Most R users know it as a statistics and visualization tool. But did you know you can also process and analyze images directly in R?

The imager package turns R into a lightweight image processing toolkit. You can load photos, apply filters, detect edges, segment regions, and even prototype computer vision workflows without leaving R.

Some things you can do with imager:
🔹 Read and write image files
🔹 Apply blurring, sharpening, and transformations
🔹 Run edge detection and feature extraction
🔹 Work with color channels and pixel-level data
🔹 Visualize results interactively inside R

The figure below shows several examples from the package website: detecting objects in a star field, applying abstract transformations, filtering a sailboat image, and highlighting motion differences between video frames.

You can find the package website here: https://t.co/NWDdMYBzNs
