For years, turf insect management programs have relied heavily on a familiar set of chemistries. While these tools remain valuable, the industry continues to face increasing pressure from resistance concerns, inconsistent mid-season performance, and the need for more targeted insect control. Introducing Doxem T&O: the first liquid indoxacarb formulation for turf and ornamental professionals.
Formulation Innovation from Quali-Pro
Indoxacarb has historically only been available in dry granular formulations for professional turf programs. Doxem T&O changes that by delivering indoxacarb in a modern suspension concentrate (SC) formulation designed specifically for today’s spray operations and performance expectations.
Liquid indoxacarb improves how the active ingredient is delivered in the field. The majority of individual particle sizes in Doxem T&O are over 36 times smaller than the WDG standard. This attribute of the superior SC formulation allows indoxacarb to disperse more evenly across leaf surfaces and move into dense turf canopies, helping place the active ingredient in protected areas where foliar-feeding larvae are active. This improved dispersion also supports movement into the soil profile, increasing consistency against soil-dwelling pests.
From an operational standpoint, formulation matters just as much as efficacy. Unlike water-dispersible granules (WDGs), which contain abrasive particles that can accelerate wear on pumps, seals, and filters, the liquid SC formulation minimizes abrasion and helps extend spray equipment life. In addition, WDG formulations can settle out of suspension without constant agitation, increasing the risk of uneven application and inconsistent performance. The SC formulation maintains uniform suspension, providing reliable delivery from the first acre to the last (Figure 1).

The competitor water-dispersible granule (WDG) formulation (left) exhibits visible particulate settling after 20 minutes of standing, indicating poor suspension stability. In contrast, Doxem T&O (right) remains uniformly suspended with no visible settling after the same 20-minute interval, demonstrating superior formulation quality, suspension stability, and reduced risk of inconsistent application or equipment issues.
The result is a formulation that not only enhances biological performance, but also fits seamlessly into existing spray programs. Offering greater stability, better coverage, and improved application confidence. Liquid indoxacarb brings a proven active ingredient into modern turf management. Protecting equipment, improving placement, and delivering more consistent results where insects are feeding.
A “New” Mode of Action for Many Superintendents
Because historical adoption of indoxacarb in turf has been limited, Doxem T&O effectively introduces a new mode of action to many programs. This creates an opportunity to diversify insect management strategies, strengthen resistance management, and rethink how mid-season insect pressure is addressed.
While indoxacarb itself is not a new active ingredient, many superintendents have never successfully incorporated it into their insect management programs. With this advanced formulation, indoxacarb becomes a new tool for many turfgrass managers.
Where Indoxacarb Fits in Modern Turf Programs
Successful insect management programs are built by combining complementary tools that target different pests, life stages, and timing windows. Doxem T&O fills a gap that many modern programs are missing by providing quick feeding-stage control with a distinct mode of action.
Doxem T&O controls a broad pest spectrum of cool and warm-season pests, including annual bluegrass weevil (ABW) adults and late-stage larvae, turf-feeding caterpillars such as armyworms, cutworms, and sod webworms, mole crickets, and nuisance ants. Because indoxacarb works through ingestion, it performs best when insects are actively feeding, making it an effective option during mid-season pressure when damage is occurring, and rapid feeding cessation is critical.
Indoxacarb (IRAC Group 22A) complements other chemistries by providing a different mode of action that fits naturally into rotation-based programs and helps reduce overreliance on a limited set of actives. This makes Doxem T&O an ideal mid-season or responsive application when pests are present and feeding. Across both cool- and warm-season turf systems, Doxem T&O functions as the missing “puzzle piece”, bridging the gap between early-season prevention and later-season protection.

How Indoxacarb Works: Activated by the Insect
Indoxacarb belongs to IRAC Group 22A and functions as a sodium channel blocker, but with an important distinction. Indoxacarb is biologically activated inside the insect into its toxic form. This unique activation process increases selectivity and contributes to reduced non-target impact. Once activated, indoxacarb disrupts normal nerve signaling, leading to paralysis and eventual death.
This mode of action is fundamentally different from other chemistries, making indoxacarb an important resistance-management tool in rotation-based programs.
Why Ingestion-Based Control Matters in Turf
Most damaging turf insects cause injury while feeding. Yet many insecticide programs still depend heavily on contact activity or root-uptake systemics that may not align perfectly with insect behavior during peak pressure. Indoxacarb works differently.
As an ingestion-based insecticide, indoxacarb controls insects when they consume treated plant tissue. Once ingested, feeding stops quickly, often well before mortality occurs, helping to protect turf quickly during high-pressure windows. This is particularly important for annual bluegrass weevil, turf-feeding caterpillars, and other chewing insects where visible damage can escalate quickly.
By targeting insects at their most destructive life stage, ingestion-based control improves consistency under real-world turf conditions, including dense canopies and thatch where contact coverage can be limited.
