    Here in South Texas we are getting drenched with rain. A good amount of lawns even ones fertilized are turning yellow or a lime color. Some have the entire section turning yellow(lime). They are not in circles. It looks like the color is draining out of the blades. Is it a lack of iron or nitro or maybe yellow patch. Have one customer that has a 3 section yard. The main section is as green as green, the other 2 small sections are entirely yellow. Would it be safe to asume a fungus ( overwater from rain) and apply for yellow patch? Use Iron product, or re-fertilize. BTW all are on St. Augustine grass.

    Easy quick and cheap way to find out is to treat some of the areas with Ferromec. If it responds then you have your answer.
