Drought and Triclopyr on Clopyralid Efficacy in Honey Mesquite

July 17, 2024 by casey.matzke

Ever wonder the effectiveness of herbicides on honey mesquite during drought? Well, researchers from our department were wondering the same thing and studied how drought effects herbicide efficacy in herbaceous and woody plants. There were chamber studies conducted to evaluate the influence of water stress and triclopyr on the absorption and translocation of clopyralid in greenhouse-grown honey mesquite. Clopyralid is an auxin-type herbicide highly effective at honey mesquite control. It is often used alone or in combinations with other active ingredients to form common honey mesquite foliar-applied herbicides like Sonora™ and Sendero™.

Texas + Water – June Update

June 26, 2024 by casey.matzke

Hurricane season is coming fast and furious! NOAA is predicting an above-normal hurricane season, forecasting 17 – 25 named storms (winds higher than 39 mph), 8-13 hurricanes (winds of 74 mph or higher) and 4-7 major hurricanes (Cats 3, 4, or 5 with winds of 111 mph or higher). The sea-surface temperatures are already exceeding last year’s temperatures. The figure above shows the differences in temperatures from this year and previous years. With all this in mind, NOAA is predicting an 85% above-normal season. The season stretches from June 1st – November 30th.

Extreme Drought Impacts have been Underestimated in Grasslands and Shrublands Globally

June 12, 2024 by casey.matzke

As the climate is changing so is the frequency and severity of short-term drought events. A new study by Dr. Bill Rogers and others (the study has over 169 authors from around the world!) showed that while drought has intensified, the effects on the functioning ecosystem remain largely unresolved and unrecovered. This is due to the differences in variations of drought and differences in ecosystems that potentially mediate drought impacts. This fascinating new research from Dr. Rogers and team used a coordinated distributed experiment to quantify the impact of short-term drought on grassland and shrubland ecosystems from across the world.

Five Facts About the United States Drought Monitor

May 22, 2024 by casey.matzke

This is likely no surprise to you, but drought persists across the western U.S. and is intensifying in some areas. No geographic area is immune to the potential of drought at any given time. The U.S. Drought Monitor provides a weekly drought assessment, and it plays an important role in USDA programs that help farmers and ranchers recover from drought.

Monthly Drought and Weather Update!

November 8, 2023 by casey.matzke

The National Oceanic and Atmospheric Administration released its winter outlook. For Texas, we are looking at near-normal temperatures and wetter-than-normal conditions. While there are some potential drought improvements, it is expected to hang around. Figure 1b below gives us a three-month precipitation outlook.

Monthly Drought Update and El Niño Possibility!

October 11, 2023 by casey.matzke

The last three years have been years of La Niñas, while there is some chatter of a super El Niño coming, right now there is a 71 % chance of a strong El Niño developing (defined as a sea-surface temperature greater than or equal to 1.5 degrees Celsius). Figure 6a illustrates El Niño conditions exceeding 95% chance of extending through the winter, with growing chances of more neutral conditions in early Spring 2024.

Weak El Niño Now, But Likely to Grow Through Winter

July 26, 2023 by casey.matzke

Despite being weak, El Niño conditions continue to be in place, after the event was deemed officially underway a month ago. This is the first El Niño in four years and there is a 90% chance that these conditions will remain throughout winter.

NIFA Invests $9 million in Extension, Education and USDA Climate Hubs Partnership

July 19, 2023 by casey.matzke

We are excited to announce that Drs. Morgan Treadwell, Melissa Shehane, and Ben Wu will be continuing education and extension Prairie Project efforts after receiving a $1.5 million grant from the USDA-NIFA Extension, Education and USDA Climate Hubs Partnership program area priority within AFRI’s Foundational and Applied Science Program to support a project titled, “Promoting Climate-Smart Agricultural Practice to Reduce Risk and Impacts of Drought, Wildfire and Woody Encroachment on Livestock Production.”

Intense and Lengthened Fire Weather Conditions – Becoming More Common

June 28, 2023 by casey.matzke

As the peak of summer approaches, drought conditions become alarmingly extended, and extended triple digit heat cripples and crunches native grasses, and convective storms rage dry lightning, it’s crucial that ranchers equip themselves with the knowledge and tools to combat any extreme conditions, namely summer wildfire season. Fire weather days are a mix of low humidity, strong winds and high temperatures. The number of these days has increased in the lower 48 states in the past 50 years alone.

A Drought, El Niño, and Forage Update

June 14, 2023 by casey.matzke

Parts of Texas have received quite a bit of rain over the last month, some more than 5 inches, while some parts in West Texas have seen less than an inch. However, the rain across the state has helped significantly with drought conditions.
