Invora Huisache Cut-Stump Treatments Atascosa Final

Summary
Three rates of Invora and one rate of Remedy Ultra were used to treat huisache using the cut-stump method. At one-year post-treatment, all treatments exhibited 100% plant-mortality. Final evaluations will be conducted in 2023.
Objective
The purpose of this project was to investigate Invora cut-stump rates for huisahce contro

2021-23 Ground Broadcast Juvenile Huisache Control Atascosa & Guadalupe Final

Summary
Four treatments with Invora herbicide were applied at sites in Atascosa and Guadalupe Counties in October and November 2021. At one-year, apparent plant-mortality for all treatments was above 80%. However, the lowest rate of Invora appears to be less consistent than other treatments.
Objective
This project explores followup treatment options for controlling juvenile huisache plants

Control of Key Weeds in South Texas Peanut

Summary
Everman et al. (2008) found that the critical weed free period of broadleaf weed interference in peanut was approximately eight weeks after planting, thus effective early-season control is of utmost importance for maintaining yield potential. Palmer amaranth (Amaranthus palmeri S. Wats.) emerging with the crop is capable of out-competing peanut for sunlight, water, and nutrients and is likely to produce extremely large amounts of seed if allowed to compete season-long (Mahoney et al. 2021). Burke et al (2007) found that peanut yield was decreased 28% due to season-long competition from one Palmer amaranth individual plant per meter of row.
Objective
In a previous study near Pearsall, TX in 2021, effective season-long control of Palmer amaranth was achieved with Prowl H2O + Valor + Dual Magnum PRE followed by Dual Magnum + 2,4-DB MPOST (98% control), Prowl H2O + Dual Magnum PRE followed by Dual Magnum + 2,4-DB MPOST (97%), Prowl H2O + Valor + Dual Magnum PRE (95%), Prowl H2O PRE followed by imazapic + 2,4-DB EPOST (92%), Prowl H2O PRE followed by Anthem Flex + 2,4-DB EPOST (88%), Prowl H2O + Dual Magnum PRE (83%), Prowl H2O + Valor PRE (78%), and Prowl H2O + Anthem Flex (78%)
The objective of this study was to evaluate the efficacy of herbicide programs for season-long control of key weed species and crop safety.

Beef Studies

Beef 706 -Result Demonstration Report

Summary
Cow/calf producers are faced with several production and marketing alternatives. Knowledge of factors affecting phases of production beyond weaning will result in a more comprehensive understanding of the entire beef industry and better decision making.
Objective
The program is designed to educate producers in the selection, feeding and processing phases of beef production and to demonstrate individual animal variation in feed yard performance, carcass merit and economic return.

Brush Country Fecal Analysis 2022 & 2023 Progress Report Atascosa Update

Summary
Cow/calf producers are faced with ongoing challenges in managing beef cattle herds for internal parasites that may reduce the performance of their herds. In addition, resistance to dewormers used to control gastrointestinal internal parasites (GIN) is a severe problem recognized worldwide. No new classes of dewormers have been released in the U.S. since the 1980s. However, during the last decade, parasite resistance to dewormers has become more prominent, requiring new control strategies. This project aims to evaluate Texas cattle ranches to determine the prevalence of resistance to current dewormers and develop improved control strategies.
Objective
The Fecal Analysis is utilized to see if beef cattle de-wormers are effective against internal parasites and to help identify if resistance is occurring. With the use of a de-wormer it should reduce the population of internal parasites by 90% to 100% at the 14 day evaluation time. If your de-wormer is 80% effective you are leaving 20% of your parasites behind that are resistant.

 

Crop Studies

2022 Peanut Variety Trials & Breeding Lines

Summary
The TAMU Peanut project had replicated yield trials located in South Texas, (Pearsall, Dilley, and Derby). 5 small plot Advanced Line Tests (ALT’s) and 2 large plot Combine Trials across Texas as well as two replicated screening nurseries for Sclerotinia and Leafspot resistance. We narrowed down lines developed for drought tolerance to one high performing line in our ALT test in order to continue to get more accurate information on the line’s performance. Two top performing candidates were included from previous year’s results. Thirteen new breeding lines were included that were top candidates for the Multiple Disease Resistance Test and from the High Yield and Grade tests and 5 commercial checks Georgia 16HO, AG18, Georgia 09B, Georgia 14N, Webb and NemaTAM II. Across the state results for individual test were statistically revealing however when combined the yield and value per acre results did not prove to be statistically significant. However, for brevity the combined analysis is presented for discussion.
