Protectant (contact) fungicides, such as the in organics (copper, FRAC group M01) and sulfur (FRAC code M02); the dithiocarbamates (mancozeb, M03), phthalimides (Captan, M04), and chloronitriles (chlorothalonil, M05) are fungicides which have a low chance for fungicide resistance to develop. Protectant fungicides typically offer broad spectrum control for many different pathogens.Why wouldn’t fungi develop resistance […]

As the weather warms up, prepare yourself to evaluate the heat risk for outdoor tasks. We often use a weather application on our phone to check the daily high and low temperature, but air temperature alone is not sufficient to evaluate heat risk. Heat index is a more appropriate measurement because it combines the effects […]

During moderate activity, the CDC recommends drinking at least 1cup of water every 15-20 minutes to replace water lost through sweat. Sports drinks are […]
