Mushrooms in the Garden Beds
You may have seen some mushrooms popping up in your garden beds. Usually, you see them most in beds that are mulched with bark or shredded wood; essentially a recycled wood product. The Texas Plant Disease Diagnostic Lab gets a lot of questions with regards to these sightings, everything from “Is it dangerous?”, “ Is it poisonous?”, “Will it kill my plants?”, to “How do I get rid of it?” Let’s break it down. It is dangerous? The short answer is PROBABLY NOT. Many times, the mushrooms you see are… Read More →
Tours and trainings at the Plant Clinic
Fewer samples come into the Texas Plant Disease Diagnostic Lab in the winter months. Rightly so, as most plants are dormant at this time. However, things are not slow at the Plant Clinic. Fall and winter months are filled with various programs.

We also host some group visits… Read More →

In fact, there are 2 related types of phytoplasmas that are well known to affect palms. One is called Lethal Yellowing – a common problem on coconuts in… Read More →
Upcoming Potential Changes to the Plant Clinic and Extension Plant Pathology
Despite the cold and nasty conditions, the majority of the Extension plant pathologists and program specialists made it to Kingsville for the 2011 Extension Plant Pathology Retreat. Current and pressing issues that will impact this unit of the Department of Plant Pathology & Microbiology were discussed, and in case you missed what has been going on, Texas is going through (like many other states) some budgetary issues. As a result, there is fear that state funding for the Extension program (and others too) will be affected adversely. This situation has prompted… Read More →
