Spring in Texas often brings warm temperatures along with frequent rain and storm events, creating highly favorable conditions for increased pest pressure in nurseries, greenhouses, and landscape systems. Elevated humidity and excess moisture significantly enhance pest development, survival, and reproduction, making this season particularly challenging for growers. These environmental conditions not only accelerate pest life cycles but also create ideal microhabitats for hidden and soil-associated pests, increasing the risk of sudden infestations and economic losses. Favorable Conditions for Pest OutbreaksSoft-bodied insects such as aphids, whiteflies, and thrips thrive under warm, humid conditions commonly observed during spring. The flush of new plant growth during this period provides tender, nutrient-rich tissues that are highly attractive for feeding and reproduction. As a result, pest populations can increase rapidly within a short period, often going unnoticed until visible damage appears. Without timely monitoring and intervention, these pests can quickly reach damaging levels and affect plant quality and marketability. Soil and Moisture Associated Pests Prolonged wet conditions create ideal environments for pests such as fungus gnats and shore flies, particularly in greenhouse and nursery production systems. Their larvae develop in moist growing media, feeding on organic matter and plant roots, which can weaken plants and reduce overall vigor. Additionally, pests like the European pepper moth benefit from high moisture conditions, as their larvae remain concealed in the lower canopy or within the growing media. This hidden feeding behavior, combined with favorable environmental conditions, makes early detection difficult and allows populations to build up before noticeable symptoms appear. Pest Spread and Increased Activity Rainfall and storm events can also contribute to the spread of pests within production systems. Splashing water can move infested soil, plant debris, eggs, and larvae between containers or across growing areas, facilitating rapid dispersal. Furthermore, outdoor pests such as caterpillars and beetles often become more active following rainfall, increasing feeding activity and the likelihood of damage. Wind and storm movement can also aid in dispersing adult insects into new areas, compounding pest pressure. Challenges in Pest Control Frequent rainfall presents additional challenges by reducing the effectiveness of insecticide applications. Rain can wash off residues from plant surfaces, shortening the duration of control and requiring more precise timing of applications. High humidity may also affect product performance and pest exposure, making control less consistent during extended wet periods. Take-Home Message Overall, rainy spring weather creates ideal conditions for pest outbreaks by enhancing survival, reproduction, and spread, while simultaneously reducing control effectiveness. Under these conditions, consistent scouting, proper irrigation management, and timely, integrated interventions are essential to minimize pest impact and maintain plant quality and marketability.

Rafia Khan, Ph. D. Assistant Professor and Extension Specialist Texas A&M AgriLife Research and Extension Center Overton, TX. Crape myrtle bark scale (CMBS), Acanthococcus lagerstroemiae, has become a persistent and economically important pest of crape myrtle in Texas landscapes and nurseries. Early spring is a critical time to detect and manage this pest before populations build and become more difficult to control. Identification and Early SignsCMBS primarily colonizes trunks, branches, and twigs of crape myrtle. The most recognizable sign is the presence of small, white to gray, felt-like encrustations on the bark. These are the adult females, which produce a waxy covering that protects them from environmental stress and some control measures. One of the earliest and most noticeable symptoms in spring is the development of black sooty mold on the bark and surrounding surfaces. This mold grows on honeydew excreted by the feeding scales and often serves as the first visual cue for infestation. Heavy infestations can lead to reduced plant vigor, poor flowering, and aesthetic decline, key concerns for both growers and landscape managers. During early spring, overwintering populations begin to resume activity. Crawlers (the mobile, immature stage) start emerging as temperatures increase, making this the most vulnerable stage for management interventions. Monitoring StrategiesRegular scouting should begin in early spring (March–April in most parts of Texas). Inspect the bark closely, especially in crevices and around pruning cuts. Look for both the white scale coverings and the associated sooty mold. To detect crawler activity, double-sided tape can be wrapped around infested branches. The presence of tiny pinkish crawlers on the tape indicates active emergence and signals the optimal timing for certain treatments. Management ApproachesAn integrated pest management (IPM) approach is essential for effective CMBS control. Cultural and Mechanical Control: Light infestations can be managed by physically removing scales using a soft brush or by washing the bark with a strong stream of water. Pruning heavily infested branches can also reduce pest pressure, but care should be taken to properly dispose of infested material. Chemical Control: Early-season applications are most effective when targeted at the crawler stage. Contact insecticides (e.g., horticultural oils or insecticidal soaps) can help suppress crawler populations when coverage is thorough. These treatments should be applied when temperatures are moderate to avoid plant injury. Systemic insecticides, such as those containing dinotefuran or imidacloprid, can provide longer-term control. Soil drenches or trunk applications applied in spring, allow the active ingredient to move within the plant and target feeding scales. However, timing is critical; applications should be made early enough to coincide with active feeding. ConclusionEarly detection and timely intervention are key to managing crape myrtle bark scale. By combining careful monitoring with targeted cultural and chemical controls, growers and landscape professionals can minimize damage and maintain the health and aesthetic value of crape myrtle plantings throughout the growing season.

Congress is currently working on the next Farm Bill, and decisions being made right now will directly impact Texas nursery and landscape businesses. TNLA members are encouraged to take five minutes to contact their Members of Congress and urge support for the Farm Bill and its specialty crop provisions. Just last month, TNLA provided a full breakdown of the Farm Bill and what it means for horticulture and specialty crops. Now, as the bill moves forward in Congress, it’s time to take action. Lawmakers need to hear directly from the businesses affected by these policies. Your voice helps ensure the green industry is represented as this legislation moves forward. The Background: Why the Farm Bill Matters The Farm Bill is the primary piece of legislation that shapes federal agricultural policy in the United States. While it is often associated with traditional row crops, the Farm Bill has become increasingly important for specialty crops, including nursery and greenhouse production, as well as the broader green industry. It has been nearly a decade since Congress passed a full Farm Bill. During that time, the industry has operated under short-term extensions while facing historic challenges, including freezes, drought, labor shortages, supply chain disruptions, and rising input costs. The current proposal, known as the Farm, Food, and National Security Act of 2026, represents the first major opportunity in years to update policies that directly affect our industry. How It Affects the Green Industry The Farm Bill includes several provisions that impact the green industry supply chain: from growers to landscapers to suppliers. Stronger Risk Management Tools Improvements to specialty crop insurance help address long-standing gaps compared to traditional agriculture, providing better protection against weather-related losses. Improved Disaster Assistance Updates to programs like the Tree Assistance Program (TAP) improve how quickly and effectively growers can recover from losses, with added flexibility for replanting. A Permanent Emergency Assistance Framework The bill establishes a standing framework for specialty crop disaster assistance, providing more predictability instead of relying on ad hoc relief. Water & Conservation Programs Expanded conservation programs support irrigation efficiency and water stewardship, helping offset costs for implementing water-saving practices. Research, Grants & Innovation Farm Bill funding supports research, extension services, and grant programs that improve pest management, develop resilient plant varieties, advance automation, and expand market opportunities. In Texas, many of these programs are delivered through university and extension partnerships that directly impact day-to-day operations for green industry businesses. Why This Matters Now The green industry plays a significant role in Texas’s economy, but it faces unique challenges that require policies tailored to specialty crops. This Farm Bill represents meaningful progress in addressing those needs: strengthening risk management, improving disaster response, supporting water efficiency, and investing in long-term innovation. As Congress continues to debate the legislation, it is important that policymakers understand the role and needs of our industry. TNLA Working for You The Texas Nursery & Landscape Association is actively engaged in monitoring the Farm Bill and advocating for policies that support specialty crops and the green industry. Through coordination with national partners and direct engagement with policymakers, TNLA is working to ensure our industry’s voice is heard. Bottom Line The Farm Bill is a critical opportunity to strengthen the long-term stability and competitiveness of the green industry. But advocacy matters. Your participation helps ensure the green industry is represented in federal policy decisions that affect our future.

Big news for Texas—and for every community that depends on reliable water.
This November, voters will decide whether to approve the largest water investment in our state’s history: a proposed $22.5 billion over the next 22 years to fix aging infrastructure, develop new water sources, and protect the long-term water supply for rural towns, cities, and the green industry alike. This effort comes through two key pieces of legislation: ✅ Senate Bill 7 (SB 7) ✅ House Joint Resolution 7 (HJR 7) If passed, these measures would constitutionally dedicate up to $1 billion per year—from state surplus funds—to support water projects beginning in 2027 and continuing through 2047. Why It Matters Water isn’t just a resource—it’s a legacy. And Texas is facing real challenges:
This investment would support: ✔️ Desalination, water reuse, and aquifer storage projects ✔️ Upgrades to aging pipes and treatment facilities ✔️ Access to federal matching dollars ✔️ Support for small-town water systems Governor Greg Abbott called this the “largest investment in water in Texas history”—and for good reason. 🌱 TNLA Is Involved The Texas Nursery & Landscape Association (TNLA) strongly supported this legislation and worked with lawmakers to ensure our industry’s voice was heard. Water is vital to the success of landscape businesses, growers, and garden centers across the state—and it’s critical for the health of Texas communities. What’s Next 📅 November 4, 2025 – Voters will decide the fate of HJR 7 at the ballot box. This is a rare chance to secure long-term water funding for generations to come. TNLA will be doing its part to help educate members, clients, and voters about why this matters—and we hope you will too. Let’s invest in the future of Texas—together. As the 2025 Texas Legislative Session enters its final stretch, several key bills are moving forward that could impact your business, your land, and your workforce. TNLA is closely monitoring these proposals and working to ensure your voice is heard in Austin. Here are the highlights:
🚨 Mandatory E-Verify for All Employers Senate Bill 324 (by Senator Kolkhorst) has passed the Senate and is headed to the House. If it becomes law, every Texas business—public and private—would be required to use the federal E-Verify system to confirm the legal work status of all new hires. ✅ What this means for you:
🌎 Foreign Ownership of Land Restrictions Senate Bill 17 (by Kolkhorst and Hefner) aims to ban certain foreign entities from buying land in Texas, including agricultural, commercial, industrial, and residential property. The goal is national security, targeting countries like China, Russia, Iran, and North Korea. ⚠️ While U.S. citizens and lawful permanent residents are exempt, the bill has raised concerns about:
TNLA is watching this bill closely and urging lawmakers to consider how it might impact agriculture and green industry sectors. 🪴 Plant Pest Alert System Moving Forward There’s good news for growers and landscape pros: House Bill 1592 (by Rep. Plesa and supported by TNLA) has passed the Texas House! 📢 This bill creates an opt-in email alert system to notify you of pest and plant disease outbreaks across Texas—helping businesses respond quickly and protect their crops and landscapes. The system will be managed by Texas A&M AgriLife Extension. ♻️ Protecting Composting and Sustainability TNLA is also working on several bills related to food waste composting facilities (SB 2078/HB 4086 and HB 4271/SB 2240). These efforts come in response to proposed changes in Lee County. We’re working to make sure any new policies:
TNLA Is Working for You We’re actively engaged in advocacy every step of the way—reviewing language, testifying at hearings, and keeping members informed. Your business, your land, and your workforce matter to us. Stay tuned for more updates as the session continues—and thank you for being a part of TNLA. |
