CELINA — Rose rosette disease – what it is and how experts are dealing with it – will be the topic of a meeting Nov. 12 at Chambersville Tree Farms, 7032 County Road 971, Celina.
The event will be 8:30 a.m.-12:30 p.m. and is free to the public, according to Dr. Kevin Ong, director of the Texas A&M AgriLife Extension Service’s Plant Disease Diagnostic Lab in College Station.
Rose rosette is a fatal viral disease spread by mites onto rose bushes. The disease leads to excessive thorn production, leaf distortion and excessive stem development, known as witches broom, at the ends of branches, according to Dr. Michael Merchant, AgriLife Extension entomologist in Dallas. An introduction to the disease will be presented by Maddi Shires, a plant pathology doctoral student at Texas A&M University in College Station. Dr. Greg Church, AgriLife Extension horticulture agent in Collin County, will talk about the status of the disease there.
Dr. Jim Amrine, professor emeritus of entomology at West Virginia University, will discuss points to remember about the spread of the disease in roses. Dr. Mark Windham, distinguished professor of ornamental pathology at the University of Tennessee’s Institute of Agriculture, will talk about proactive management strategies to combat the disease.
The challenges of breeding rose rosette-resistant roses will be the topic for Dr. David Byrne, professor and Basye Endowed Chair in Rose Genetics at Texas A&M University. Ong will conclude the event with a discussion on how the diagnostic lab can assist in finding rose rosette disease-resistant or -tolerant rose varieties.

With the prolonged drought, most pastures in Oklahoma end up in poor condition. With the lack of available forage, animals may go in search of alternative foods.
If oak trees are in the pastures, acorns may be a favorite meal for some livestock in the fall. This may result in oak poisoning.
Oak leaves, twigs, buds, and acorns may be toxic to some animals when consumed.

There are a handful of grasses on North Texas grazing lands ranchers need to know, not because they are highly desirable, but rather because they are not of much value. I call them “decom” plants, which is am acronym for “Don’t Ever Count On Me.” Silver bluestem is a “decom” grass.
Silver bluestem is a perennial which grows in all areas of Texas. It can survive in almost all soil types, and in full sun conditions or in semi shade. It grows up to three feet tall and is easily recognized with the presence of the white fuzzy seed head. Also, one of the identifying characteristics of Silver bluestem is a bend in the stems at each node, causing the plants to take on a rounded shape as they mature.

Fall is here which means winter is closing in on us and before we officially get into winter, we need to make sure our factories are either producing or will be producing in a few months.
We have been pregnancy testing our cows this fall and if they are not bred or nursing a calf, we are bidding them adios. With annual costs somewhere between $900.00 and $1,000.00 per cow, those cows not producing a live weaned calf are costing us quite a bit.
