Xentari® Biological Insecticide: Effective Control for Lepidopteran Pests

Xentari®, from Certis, is a biological insecticide designed to control lepidopteran larvae such as caterpillars, loopers, and moths. Using the powerful strain Bacillus thuringiensis var. aizawai (Bta), Xentari stops larvae feeding within minutes of consumption and leads to their death within a few days. Xentari is suitable for use on a variety of crops, including vegetables, fruits, nuts, and ornamentals, and is OMRI-listed for organic farming systems.

Why Choose Xentari®?

• Targeted Control: Highly effective against caterpillars, armyworms, and diamondback moths.
• Organic Compatibility: OMRI-listed, making it safe for organic farming.
• Fast Action: Stops larvae feeding within minutes, killing them in days.
• Eco-Friendly: Safe for beneficial insects like bees and pollinators.
• Resistance Management: No cross-resistance with other insecticides, supporting sustainable pest control.

Features & Benefits

Xentari® provides consistent and reliable pest control for growers. It features the ABTS-1857 strain of Bacillus thuringiensis subspecies aizawai (Bta), producing insecticidal proteins such as Cry1A, Cry1C, and Cry1D, which are effective against tough pests like armyworms and diamondback moths.

• Fast-Acting: Larvae stop feeding almost immediately, leading to quicker pest elimination.
• Residue-Free: Xentari is exempt from residue tolerance limits, with a 0-day Pre-Harvest Interval (PHI) and a 4-hour Restricted Entry Interval (REI), allowing for fast re-entry and harvest after application (check local guidelines).
• Effective Resistance Management: Helps reduce the risk of pest resistance, as it never developed cross-resistance with any other insecticide class.
• Compatible: Can be tank-mixed with most insecticides, fungicides, and foliar nutrients for efficient pest management.
• Broad Compatibility: Suitable for a wide range of crops including vegetables, fruits, tree nuts, and ornamentals.

Applications for Key Crops

Xentari® is suitable for many crop types, including:

• Berries
• Ornamentals
• Plantation Crops
• Row Crops
• Tree Fruits
• Tree Nuts
• Vegetables

Why It Works

Xentari’s unique profile of Cry proteins provides exceptional control over difficult-to-manage pests like Spodoptera (armyworm) and Plutella xylostella (diamondback moth). These proteins disrupt the larvae’s digestive system, stopping feeding and eventually killing them. Xentari’s fast-acting nature and broad-spectrum efficacy make it a vital tool in Integrated Pest Management (IPM) programs.

Environmental & Worker Safety

Xentari® is designed to protect the environment and workers. Its formulation is non-toxic to beneficial insects such as bees and natural predators used in pest control, making it safe for pollination and integrated pest management. It also features some of the shortest REI and PHI times allowed by law, enabling quick re-entry and harvest.

Application Flexibility

Xentari is highly flexible and can be tank-mixed with most insecticides, fungicides, and foliar nutrients to streamline pest management efforts. This makes it an excellent choice for growers looking to integrate it into their overall crop protection program.

Always read and follow the label instructions for application and safety guidelines.
