UTRGV Integrated Pest Control Management

UTRGV Edinburg Grounds Supervisor holds a current Ornamental Pest Control License that is issued under the Texas Department of Agriculture (TDA). Under TDA requirements, the University is required to implement an “integrated pest control management program” which entails close supervision of plants and turf materials. Through the use environmentally friendly practices such as using compost and other organic materials to control pests, insects and weeds, we are able to maintain a healthy landscape while minimizing the use of chemicals which have the potential to create harm due to their residual elements. Other practices often include proper selection of plants that minimize the risk of attracting pests that would cause damage to the general landscape. In spite of multiple requests by the community to introduce citrus trees to the landscape, the Grounds Department has abstained from implementing the recommendation due to the risks associated with attracting pests and diseases.
Close supervision and surveillance of the landscape is perhaps the most important practice in maintaining aesthetically pleasing university environment. Routine inspections of the campus allow for the staff to catch these problem early before they become critical response items.

The department performs regular monitoring for pests. Once a pest is detected and a threshold is reached, our first approach is to attempt to eliminate the elements that might be promoting the invasion. If the condition persists our next approach is to follow with a non mechanical method in combination with pesticides (using expert advice).

The UTRGV Agroecology Research and Teaching Garden has been annually certified since 2015 by a USDA National Organic Program-authorized certifying agent (Nature’s International Certification Service), following all USDA organic regulations and compliant with the standards set by the National Organic Standards Board. Each year we provide all of the documentation to maintain our eligibility for this certification, and are inspected by a third party to verify our compliance, to certify that:
·we maintain our facility without excluded methods (e.g.,genetic engineering, ionizing radiation, or sewage sludge).
·Crops maintained using allowed substances.

Oscar Villarreal, Director for Facilities Management, also addressed the standards for organic areas in a 2014 letter to Dr. Alex Racelis:
"This letter is to certify that the property in which the UT[PA] agro-ecology garden sits has been free of fertilizers, pesticides, or any other chemical use for more than three years. Since the baseball stadium and associated activities have been relocated to the Edinburg Baseball Park, no agriculture or landscaping activities have occurred on this property. Furthermore, with the understanding that the garden would be used as a certified organic gardening facility, our Facilities Management took extra care in assuring that no chemical contaminants would be used within gardening areas that had the potential for affecting research gardening projects."

An ISA Certified Arborist (http://www.isa-arbor.com/certification/index.aspx) shall manage any contract work dealing with trees on The University of Texas at UTRGV campus. All tree care activities shall require at minimum, an ISA Certified Tree Worker to be on site at all times. UTRGV tree-related construction standards and specifications can be found on the
PMCS website at: http://www.utexas.edu/pmcs/dcstandards/.
Additional construction details for trees are forthcoming. Trees to be planted and managed on construction sites at UTRGV shall adhere to specifications based on the most recent editions of the following:
2.00.1 American National Standards Institute (ANSI)
Z60.1-2013
2.00.2 ANSI A300-01 Pruning (2014)

The following species are not required to be replaced on any site:
Chinese Parasol, Chinese Tallow, Chinaberry, Golden Rain Tree, Hackberry, Ashe Juniper, Ligustrum species, Vitex, Mimosa, Nandina, Paper Mulberry, Photinia,
Pyracantha Russian Olive, Salt Cedar, Siberian Elm, Tree of Heaven and White Mulberry.

Minimizing the use of potable water for irrigation.

The objective entails a modification of campus community culture—to one that focuses on the preservation of natural resources while minimizing our emission of carbon. The vision is to transition all landscape and grounds maintenance activities to a more ecologically sound operation by extending awareness and educational programs in support of this.
For most of our areas, weed control is managed by maintaining a healthy turf. This is accomplished by controlling watering schedules, turf height and re-seeding eroded areas. UTRGV utilizes a hydromulcher for seeding and fertilizing and a wood chipper to produce mulch from recycled brush and other organic materials resulting in a more beautiful and sustainable future for campus grounds.

The University enjoys reduced energy costs due to the shade provided by the tree canopy, and local businesses experience increased property value and business traffic due to their beauty. Trees also serve as strategic barriers to reduce noise, glare, and odors. The
trees that make up the campus forest are a good mixture of small, medium and large trees optimized for the available space. UTRGV maintains adequate tree canopy cover by planting trees, assisting with developing tree ordinances and tree-related policies.

UTRGV Garden & Greenhouse http://www.utrgv.edu/agroecology/facilities/utrgv-garden-and-greenhouse/index.htm

UTRGV is proud to be the first-ever Texas university to have a USDA certified organic garden and greenhouse!

The garden facility finished construction for its first phase early in 2014 and is located at the North East wing near the UTRGV Child Development Center. There has been 7,500 ft2 of land fully equipped with irrigation, access to the tool shed, and a shade-house dedicated for research under the Agroecology program. Adjacent to this is the UTRGV's state-of-the-art greenhouse equipped with a water wall, sprinklers, and fans ensuring optimum temperature

Research and teaching portions have already begun with the Agroecology Lab and Dr. Racelis' Agroecology class in the fall of 2014. This fall the garden was lush with okra, eggplant, peppers, basil, tomatoes, cucumber, beets, radishes, lettuce, kale, marigolds, zinnia, and cover crops growing, spring planting in underway!

The garden includes the 7,500 ft2 of land fully equipped with irrigation, access to the tool shed, and a shade house, all adjacent to UTRGV's state-of-the-art greenhouse equipped with a water wall, sprinklers, and fans ensuring optimum temperature.

Community Garden

There has been 2,500 ft2 set aside for a community garden, which is decorated with 15 raised beds. 9 student organizations including The Environmental Awareness Club, The Garden Club, SGA, and many more have signed up to grow, maintain, and harvest their yields.

UTRGV Research

Savannah Rugg planted Buckwehat (Fagopyrum esculentum), Lablab (Lablab purpureus), Sudan Grass (Sorghum drumondii), Sunn Hemp (Crotalaria juncea), Tillage Radish (Raphanus sativus) and Winter Rye (Secale cerale) as cover crops with the purpose of recycling nutrients back into the soil. Cover crops have many benefits including the prevention of soil erosion, suppressing weeds, help in controling pests & disease and so much more.

Lindsey Richardson is working diligently on a variety of tomato heirlooms and the most effective tool for avoiding the whitefly pest and contracting tomato yellow leaf curl virus.

Maddie Marshall is conducting a companion planting experiment with the intention to reduce pest impact on brassica crops. Kale, the cash crop, will be planted with "push" species onion and cilantro to repel pests and alyssum, fennel, and dill are acting as "pull" species to attract pests to a new location. The main goal of this research is to determine what chemical volatiles are responsible for the movement of pests.

Amrita Singh has pepper, tomato, and corn growing in the greenhouse to be transplanted in the garden to undergo mycorrhizal research. She will be observing the effect on increasing productivity in organic farming and suppression of nematodes.

Off Campus Research

Some experiments, such as the cover crops and tomato research, are also conducted on local farms such as Terra Preta in Edinburg, Plantation Produce Farms at Hilltop Garden in Lyford, and Yahweh's All Natural Farm & Garden in Harlingen. We thank these farmers for their active research engagement!

Subtropical Organic Agriculture Research (SOAR)

Funded by USDA -NIFA-Organic Research Transitions program http://www.utrgv.edu/agroecology/research/soar/index.htm

Subtropical Organic Agriculture Research (SOAR) Partnership: A participatory academic program to fill research needs of farmers in S. Texas (Funded by USDA-NIFA-Organic Research Transitions program). Organic farmers in South Texas, and those interested in transitioning to organic production, face many challenges, including extremely intense pest pressure and uncertainty with changing climate and water availability. Especially since the 2011 closing of the USDA-ARS Subtropical Agricultural Research Center in Weslaco, Texas, there has been very little research support available to these growers, in one of the most important agricultural regions in Texas. Strategically situated in subtropical south Texas, the University of Texas-Rio Grande Valley will build upon its status as a USDA-designated Hispanic Serving Agricultural College and University (HSACU) by launching an innovative new academic program that engages students in rigorous, well-designed research projects designed to address real-world problems faced by organic farmers in South Texas. Using a participatory research approach, the project team will identify pressing research needs by interviewing farmers, agency staff, and organic inspectors. Students will

help design and carry out supervised research studies to answer these questions. This practical field research experience will be at the center of an innovative experiential learning emphasis that will prepare students to become effective scientific researchers and will raise their awareness of the ecological benefits of organic farming. The project will also provide an research-based educational program to inform growers, extension agents, and others about organic requirements, certification, marketing, processing facilities, enterprise budgets, and production methods. The ultimate goal of the project is to make South Texas organic producers more competitive by meeting some of their most urgent research needs and by publicizing research findings widely. In the spring of 2014, several projects looking at integrated pest management strategies, cover cropping, and sustainable weeding were conducted by our team of researchers, students, and farmers. By incorporating annual flowering plants into organic kale systems, we identified multiple hostplants that can attract beneficial insects as well as potentially repel Green Peach aphids. We also trialed four species of cover crop that are relatively new to the valley and assessed their influence on soil fertility. Student led projects have looked at relationships between tomato varieties, intercropping, yield, and biological control of whiteflies, while future studies will investigate the use of repellant plants in managing leafcutter ants.

UTRGV’s landscape management works towards the sustainable development goal of life on land by the implementation of sustainable management of our ecosystem.
