PLEASE DISINFECT YOUR PRUNING EQUIPMENT BETWEEN PLANTS! Pictured are 30-year old loropetalums that are slowly dying of bacterial canker introduced on infected pruning equipment. This disease also goes to forsythia, oleander, privet, olive and ash. Don't be a vector. #MSUext

#Hydrangea ringspot virus causes a variety of leaf symptoms, including distortion and yellow rings. It is mechanically transmitted in sap on cutting tools and hands and through propagation of infected plants. Many cultivars are tolerant, but some can be severely affected. #MSUext

On the road with Dr. Henn looking at crape myrtles that are victims of last winter’s cold snaps, possibly compounded by drought stress. If you’re seeing branch dieback, check the stem for cracks or splits in the wood. Roots are fine and will sucker. Prune out dead wood. #MSUext

Brown spot needle blight is hammering loblolly pine in MS right now. The fungal disease works its way up from the bottom of the canopy and will cause last year’s needles to drop, making the canopy look thin until this year’s needles mature. #MSUext

Do you hear what I hear? Rain has brought out a prolific crop of wood ear (Auricularia angiospermarum),a velvety fungus that decomposes dead hardwoods. Also, beautiful saccate Amanitas. Ringless, with bright white gills, a hollow stem, and a chocolate-brown central bump. #MSUext

What's in your mulch? Here outside of the lab we have a robust crop of fairy bonnets (Coprinellus disseminatus). These fragile mushrooms grow in large groups ("troops") on decaying wood and are having a big time in our landscape mulch. Also called trooping crumble caps. #MSUext

Mississippi blooms for Mother’s Day! Beautiful native blue flag iris with purple petals with a central yellow stripe, a spiky white and yellow bloom of a pond lily, and the tightly clustered pink tinged white flowers of our native redring milkweed. #MSUext

Found this lovely crop of Lentinus crinitus (hairy capped Lentinus) in the Sam D. Hamilton Noxubee Wildlife Refuge today. One of our Gulf Coast gems, this fungus grows on dead hardwoods. This is a really tough fungus and the cap and stem are covered in dense hairs. #MSUext

🎥Slime molds can really freak people out. Clarissa with our MSU Extension Plant Diagnostic Lab explains what you’re actually seeing! #MSUext

Fungal leaf diseases cause a great deal of alarm in the spring, especially when new leaves appear deformed or fall off. Don't fret - or spray! Damaged leaves will often drop and new leaves will be unaffected because the weather will no longer be conducive to infection. #MSUext

Mayapple rust is striking, with angular yellow spots on the upper surface of the leaf. Spores are produced on the underside of the leaf. This leaf has brown telial pustules. A different spore stage is orange and powdery. Mayapple is the only plant this fungus infects. #MSUext

MSU Turfgrass Field Day will be held on September 18. Check out registration/sponsorship details on our website: mafes.msstate.edu/workshops/turf/

🎥Did you know our MSU Extension Plant Diagnostic Lab can help you diagnose plant diseases and nematodes? Submission forms, instructions for sample collection and shipping, and a list of fees, are available from your county Extension office or online here: extension.msstate.edu/lab  #MSUext

Nematode counts are not always the best indicator of nematicide efficacy on turf. Focus on root health and not nematode numbers to determine if a treatment works onlinelibrary.wiley.com/doi/10.1002/it…

#SCN is present in 92% of Mississippi counties – is it in your field? 👀 Thankfully, MSU Extension has resources and recommendations specifically for your state’s pest pressure. bit.ly/4jUwqbo

Free nematode testing for Mississippi soybean growers can help shed light on nematode populations in fields. Find out how to submit samples at extension.msstate.edu/content/free-n… #MSUext

Chanterelles are up Mississippi! These young “smooth chanterelles” (Cantharellus lateritius) are characterized by their orange color, in curved margin, and a very smooth fertile surface. The cap will become more funnel-shaped with age. #MSUext

Lots of rain is making the fungi pop in MS! Wrinkled, tan jelly babies (Leotia lubrica) stain green when bruised. White clumps of false coral (Tremellodendron sp.) are jelly fungi,not the corals they resemble. Pretty little stalked scarlet caps decompose dead wood. #MSUext

Wedge-shaped areas of dark wood in a stem cross section are often indicative of canker pathogens like Botyrosphaeria and Phomopsis. Look for black pustules embedded in the bark. This tree was under severe root stress and the canker disease is likely secondary. #MSUext

Enjoyed being the quarterly nature series speaker for the Friends of Noxubee Refuge group this evening and celebrating the 85th anniversary of the Sam D. Hamilton Noxubee Wildlife Refuge! #MSUext
