When growers and landscape professionals think about insects, the first thought is often pests and the damage they cause. However, not all insects are harmful. Many beneficial insects play an important role in naturally suppressing pest populations in greenhouses, nurseries, and landscapes. These “good bugs” are valuable partners in Integrated Pest Management (IPM) programs and can help reduce reliance on chemical insecticides. Beneficial insects are a key component of Integrated Pest Management (IPM) programs. They help suppress pests naturally and can improve long-term pest management success when properly conserved or introduced into production systems. Two important groups of beneficial insects are predators and parasitoids. Predators actively consume pests throughout their life cycle. Common examples include lady beetles, green lacewings, minute pirate bugs, predatory mites, and hover fly larvae. These natural enemies feed on aphids, whiteflies, spider mites, scales, thrips, and other soft-bodied pests commonly encountered in Texas greenhouses and landscapes. Parasitoids are specialized insects, usually tiny wasps, that develop inside or on a host insect and eventually kill it. Several parasitoid species are commercially available and widely used in greenhouse biological control programs, especially for whitefly and aphid management. Parasitoids are specialized insects, usually tiny wasps, that develop inside or on a host insect and eventually kill it. Several parasitoid species are commercially available and widely used in greenhouse biological control programs, especially for whitefly and aphid management. Greenhouse environments often provide ideal conditions for biological control because temperature, humidity, and pest populations can be monitored more closely. In landscapes and nurseries, conserving naturally occurring beneficial insects can also provide significant pest suppression over time. Unfortunately, beneficial populations are frequently disrupted by unnecessary or repeated applications of broad-spectrum insecticides. One of the biggest challenges in pest management is recognizing when beneficial insects are already helping control a pest problem. In some situations, professionals may apply insecticides before evaluating predator or parasitoid activity. This can eliminate natural enemies and create secondary pest outbreaks or pest resurgence. In addition, repeated use of the same insecticide groups can contribute to pesticide resistance, making future pest management more difficult. Scouting remains one of the most important tools in preserving beneficial insects. Correct identification of both pests and beneficials allows professionals to make informed treatment decisions. When insecticide applications are necessary, selecting reduced-risk or selective products can help preserve natural enemy populations while still managing key pests. Habitat also plays a role in supporting beneficial insects. Flowering plants, reduced dust, proper irrigation management, and minimizing unnecessary pesticide exposure can all encourage beneficial activity in landscapes and production systems. Biological control is not always a complete replacement for insecticides, but it is an effective management tool when incorporated into a broader IPM strategy. As greenhouse and landscape industries continue to face challenges from invasive pests, environmental concerns, and pesticide resistance, beneficial insects should not be viewed as forgotten tools. Instead, they should be recognized as valuable partners in sustainable pest management programs. Photo credit: Rafia Khan, Ph. D.

Last week, TNLA traveled to Washington, D.C. alongside members of Texas’ green industry for the annual H-2B Fly-In. During the trip, TNLA members met directly with Congressional offices to discuss workforce challenges impacting green industry businesses across Texas. The conversations focused heavily on the seasonal H-2B VISA program. For many green industry businesses, these workers help keep projects on schedule during peak seasons while also supporting year-round American jobs within their companies. Why This Matters to Texas’ Green Industry Texas’ green industry continues to face significant workforce shortages, particularly during high-demand periods in the spring and summer. During our meetings in Washington, TNLA members had the opportunity to speak directly with Congressional staff about how these workforce challenges affect their businesses on a day-to-day basis. Members shared personal stories about trying to keep crews staffed during peak project seasons, balancing growing customer demand, and managing the uncertainty that comes with not knowing whether seasonal workers will arrive on time. Some discussed the pressure of meeting timelines for government and commercial contracts, while others explained how workforce shortages impact long-term business planning and growth. Several members also highlighted that dependable seasonal labor helps create opportunities for year-round American employees by allowing businesses to expand operations, invest in training, and move workers into higher-skilled positions over time.  One of the most impactful aspects of the trip was ensuring policymakers heard directly from employers experiencing these challenges firsthand. What Was Discussed in Washington A major focus of this year’s advocacy effort was support for the proposed “Certified Seasonal Employer” language currently being discussed in federal appropriations negotiations. The Certified Seasonal Employer proposal is designed to reward businesses that have consistently followed the rules and responsibly used the H-2B program over multiple years. Under the proposal, employers that have received H-2B labor certifications for the past five years would be allowed to maintain access to the highest number of seasonal workers they were previously certified for without those workers counting against the annual H-2B cap. One way to think about it is this: businesses that have proven year after year they are compliant, dependable, and operating legally would no longer have to “re-enter the lottery” every season just to maintain the same workforce levels they have historically relied upon. Currently, the H-2B program has an annual visa cap of 66,000 per fiscal year that has not been updated in decades despite major economic growth and increased workforce demand. The proposed language would reward long-time, compliant employers (certified for the last five years) instead of forcing them to compete under the same uncertainty each season. These workers would not be included in the cap. Where the Language StandsThe Certified Seasonal Employer language is currently being discussed as part of the Fiscal Year 2027 Department of Homeland Security (DHS) Appropriations process in Congress. Rather than moving as a standalone immigration bill, the proposal is being pursued through the federal appropriations process because Congress frequently uses annual funding legislation to address operational H-2B issues and cap relief measures. In this case, industry groups are advocating for the language to be included in the baseline DHS Appropriations bill because DHS oversees key parts of the H-2B program, including visa allocation and administration. The proposal has already gained significant attention in Washington. According to industry briefings shared during the fly-in, the White House previously supported inclusion of the Certified Seasonal Employer language during earlier federal funding negotiations, and advocates are continuing to push for its inclusion in the final FY27 DHS funding package. This means the current focus is on educating Congressional offices, appropriations staff, and committee leadership about why workforce certainty is critical for seasonal employers and why long-time, compliant businesses should receive more predictability within the H-2B process. For TNLA members, the issue is not simply about increasing workforce numbers; it is about creating a more stable and predictable system that allows responsible employers to better plan projects, retain year-round employees, and continue supporting Texas’ growing economy. What Success Looks Like For TNLA members, success would mean:
TNLA appreciates the members who traveled to Washington to ensure the voice of Texas’ green industry was represented on Capitol Hill. Contact TNLA’s Legislative & Regulatory Affairs Team 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.
