A listing of various shiny apps I’ve developed:
Enter a crop rotation and herbicide program, and it will estimate the cost of herbicides, the weed control efficacy, and the risk of herbicide resistance evolution for each herbicide site of action selected.
The 4-parameter log-logistic model is commonly used in a variety of modeling, especially in weed science and other toxicology-related disciplines. This app allows you to choose different values for each parameter to see how it changes the curve.
To effectively manage weeds (especially annual weeds) over the long term, it is necessary to reduce the amount of weed seed in the soil. This is a very basic model to show how different parameters (seed production potential and efficacy of control measures) will impact the soil seed bank.
