TNLA TAILGATE TOPICS
PREPARING AN EMERGENCY RESPONSE PLAN Objective: Fully complete an emergency response plan for your company with the help of all employees and through practice.
APPLICATION: Follow the steps below to begin creating or completing an emergency response plan for your company. Take all employees' needs/concerns into consideration. Prior to completing the plan, have employees practice responding to an emergency to see if any changes need to be made. Preparing an Emergency Response Plan is highly valuable because it could possibly save your business, a life, or the environment of your community. Preparation should include input from all employees. Once a plan has been put in place, it should be made available to current and future employees and emergency response units. Step #1: Identify Potential Hazards Conduct hazardous assessment by examining equipment, chemicals/pesticides, and the spaces and places in which potentially hazardous actives could take place. Use this information to address ways to remove the hazard from work areas.
5
Step #2: Practice Responding to an Emergency Practice responding to all types of emergencies, including spills, fires, and accidents. You should be able to locate needed personal protective equipment, spill kits, fire extinguishers, and first aid kits. It is important to know how to use these items and to recognize when the situation is beyond their control. Post essential emergency phone numbers. Step #3: Write an Emergency Response Plan Complete a response plan for your company that includes input from all employees. Once completed, the plan should be updated on a regular basis. It is strongly suggested having an emergcny mailbox on site to store information for emergency response units who may respond while no on is on the property.The response plan should include the following: Who to contact in an emergency Where employees should rendezvous if evacuated Types of chemicals stored on-site Precise locations of chemical storage areas A site map of your property and facilities Assigned duties for each employee

and Catherine Simpson, Department of Plant and Soil Sciences, Texas Tech University, Lubbock, TX 79409. (gplocek@ttu.edu) Saline water has become an increasing problem in agriculture. The total dissolved solids (TDS) level in Texas has been observed in excess of the TCEQ upper limit of 1,000 ppm of salts. Irrigating crops with saline water can cause osmotic stress, reduce plant yield, and, in severe cases, cause crop failure. Different species of crop plants also have differing salinity tolerances ranging from sensitive to highly tolerant. Knowledge of these categories are important for sprout and microgreen cultivation as these tender plants generally have a lower tolerance for stress. The goal of this experiment is to compare the physiological and chemical effects of saline water on Brassica oleraceae (broccoli, moderately tolerant) and Portulaca oleracea (purslane, highly tolerant) microgreens. Both varieties of microgreens were cultivated under the same conditions and irrigated with a salinity treatment ranging from 0 dS/m to 1.5 dS/m. Once harvested, each sample was analyzed for fresh/dry weight yields to evaluate physiological effects. Vitamin C and proline content were also analyzed. The results show no effect on dry weight for either broccoli or purslane. There was an increase in fresh weight for broccoli irrigated with 1 dS/m in one of the trials. These results indicate that salinity levels commonly found in tap water have no negative effects on microgreen growth, and in some cases, some increases in yield were found.

This was expected because the Aeroponic system produced double the yield and needed more water to produce that biomass. Overall, the Aeroponic system outperformed the hydroponic system when growing lettuce. More research needs to be done to determine how well the Aeroponic system compares to a hydroponic system when scaled up to commercial size.

(hqin@bio.tamu.edu) Crapemyrtle Bark Scale (Acanthococcus lagerstroemiae; CMBS) is an invasive pest species that primarily infest crapemyrtles (Lagerstroemia spp.) in the United States. Recent reports have revealed the dire threat of CMBS to attack the U.S. native species such as American beautyberry (Callicarpa spp.) and Hypericum kalmianum L. (St. Johnswort). A better understanding of plant-insect interaction could provide alternative pest management strategies, thus increasing the effectiveness in controlling this pest insect. Therefore, we constructed the first comprehensive life table for CMBS to characterize CMBS

biological parameters, including developmental stages, reproductive behavior, and fecundity. Through the life table study, we also evaluated the effects of host plant physiological conditions on the development of the CMBS life cycle. The indirect effect of three plant nutrient conditions (water, 0.01 MS, and 0.1 MS) on CMBS populations was examined using the agestage, two-sex life table. The demographic analyses revealed that the plant nutrient conditions had significantly altered CMBS development in terms of the intrinsic rate of increase (r), the finite rate of increase (λ), the net reproductive rate (R0), and mean generation time (T). Higher r, λ, and R0 were recorded under nutrient-deficient conditions (water), while CMBS reared on plants with healthier growing conditions (0.1 MS) had the most prolonged T.

ADVOCACY REPORT 9
City of Austin Developing New Landscape and Irrigation Ordinance The City of Austin announced its intention to develop a new water conservation ordinance regulating the installation of landscape and irrigation in new residential landscapes. The city will be conducting a series of stakeholder and public meetings to gather input from the community in the development of these regulations. The ordinance could potentially limit the size of residential irrigation systems, ban non-native or adapted plants and grasses, limit the size of grass in yards. February 10th at 7 pm is the first stakeholder meeting to be conducted virtually. TNLA is encouraging local landscape contractors to become involved in the process to make sure the industry has its voice heard. You can register at https://www.speakupaustin.org/irrigation-andlandscape-ordinance-update-for-single-familyresidential Supplemental H-2B Visas Rule Released The DOL and DHS have announced their rule to release 20,000 additional H-2B visas for the first half cap. The H-2B program has seen historic increase in demand of the visas available in this year. Of the 20,000 going to be released, 13,500 visas are allotted for returning workers from the past 3 years.

In addition, long-term cap relief remains the objective to avoid this year-in-year-out fight.
