BT NOW Biological Insecticide

BT NOW is a water-based biological insecticide designed for targeted control of labeled caterpillars and other Lepidoptera larvae. Powered by Bacillus thuringiensis ssp. kurstaki strain EVB-113-19, BT NOW delivers a practical, residue-conscious solution for growers seeking effective caterpillar management across a wide range of labeled crops, ornamentals, greenhouse crops, outdoor nursery crops, and lawns. The specimen label identifies the active ingredient as Bacillus thuringiensis ssp. kurstaki strain EVB-113-19 fermentation solids, spores, and insecticidal toxins at 14.49%, with a potency of 76 billion Cabbage Looper Units per gallon.

BT NOW works when susceptible larvae ingest treated foliage. After feeding on deposits, larvae stop feeding within a few hours, helping reduce additional plant injury, and death typically occurs within 2–5 days. For best performance, apply when larvae are small, actively feeding, and at the first signs of infestation. Thorough spray coverage is essential because the product must be eaten by the target pest.

Why Choose BT NOW?

Product Advantage Grower Benefit
Water-based liquid formulation Flexible application; may be applied undiluted or diluted with water depending on coverage needs, crop size, weather, equipment, and local conditions.
Targeted biological control Designed for select Lepidopteran larvae, including many damaging caterpillars found in crops, ornamentals, greenhouses, nurseries, and lawns.
Stops feeding quickly Susceptible larvae stop feeding within hours after ingestion, reducing further crop damage potential.
4-hour REI The agricultural restricted-entry interval is 4 hours when used according to label directions.
Day-of-harvest flexibility The label states BT NOW may be applied up to and on the day of harvest.
IPM-compatible positioning The fall ornamentals guide highlights BT NOW as part of a biological caterpillar management program with Trichogramma beneficial wasps.
Beneficial-insect conscious program fit The ornamentals program guide states that BT NOW used with Trichogramma can provide caterpillar control without disrupting beneficial insect populations.
Broad labeled use sites Labeled use areas include fruits and nuts, vegetables and cole crops, herbs and spices, field crops, ornamentals, greenhouse and outdoor nursery crops, and lawns.

How BT NOW Works

Step What Happens
1. Apply to feeding sites Apply BT NOW to foliage where caterpillars are present and actively feeding. Thorough coverage is critical.
2. Larvae ingest the product BT NOW must be eaten by susceptible larvae to be effective.
3. Feeding stops After ingestion, larvae stop feeding within a few hours.
4. Larvae die Affected larvae typically die within 2–5 days.

Labeled Target Pest Categories

BT NOW is labeled for select Lepidoptera larvae across many crop and ornamental systems. Target pests vary by crop and use site, so always confirm the specific pest and rate on the current label.

Use Site / Crop Category Examples of Labeled Target Pests
Fruits & Nuts Leafrollers, navel orangeworm, peach twig borer, codling moth, fruitworms, tent caterpillars, fall webworm, cutworms, cankerworms, and other labeled larvae.
Vegetables & Cole Crops Diamondback moth, imported cabbageworm, loopers, armyworms, cutworms, webworms, hornworms, European corn borer, corn earworm, tomato fruitworm, and other labeled pests.
Herbs, Spices & Mints Loopers, diamondback moth, green cloverworm, imported cabbageworm, armyworms, European corn borer, and saltmarsh caterpillar.
Field & Specialty Crops Armyworms, loopers, saltmarsh caterpillar, green cloverworm, corn earworm, tobacco budworm, European corn borer, hemp borer, and other labeled pests.
Flowers, Bedding Plants & Ornamentals Armyworms, box tree moth, mimosa webworm, saddle caterpillar, variegated leafroller, white marked tussock moth, azalea moth, loopers, oleander moth, and omnivorous leafroller.
Greenhouse & Outdoor Nursery Crops Tomato hornworm, omnivorous leafroller, Duponchelia fovealis, Opogona sacchari, armyworms, corn earworm, tomato fruitworm, tobacco budworm, and loopers.
Lawns Cutworms, armyworms, sod webworm, and tropical sod webworm.

Application Timing Guide

Situation Recommended Approach
First signs of infestation Apply when larvae are small whenever possible.
Single-spray timing Time application when egg hatch is nearly complete, but before crop damage occurs.
Standard reapplication interval Repeat according to economic thresholds, usually every 7–14 days depending on plant growth, pest activity, and rainfall.
Rapid crop growth or overlapping pest generations Increase application frequency to every 3–7 days when conditions require more frequent coverage.
Fall ornamentals program The fall ornamentals guide recommends applying BT NOW 3–7 days after moths first lay eggs to target newly emerging larvae.
Rain considerations Do not apply when significant rainfall is imminent; the label states it is best to allow 48 hours without rain after application to retain activity.

Application & Mixing Snapshot

Technical Detail Label-Based Information
Formulation Water-based formulation; may be applied undiluted or diluted with water.
Water pH Spray water must be between pH 4 and 8 before adding BT NOW and remain in that range in the tank.
Spray mixture holding time Do not store spray mixture in spray equipment for more than 18 hours; use diluted spray mixtures within an 18-hour period.
Coverage Thorough coverage of target foliage is essential because larvae must ingest the product.
Surfactant use A spreader surfactant is recommended on difficult-to-wet foliage, such as crucifers, to improve coverage.
Chemigation May be applied only through sprinkler irrigation systems according to label directions.
Storage Store in the original container between 39°F and 68°F and use within 18 months of manufacture.

Fall Ornamentals & Biological Program Use

For ornamental growers, BT NOW can be integrated with Trichogramma beneficial wasps as part of a biological caterpillar management program. The fall ornamentals guide lists Trichogramma minutum, Trichogramma platneri, and Trichogramma brassicae as biological control partners and explains that Trichogramma targets moth and caterpillar eggs, while BT NOW helps manage hatched caterpillars that may have escaped egg parasitism.

Program Component Role in Caterpillar Management
Trichogramma spp. Targets fresh moth and caterpillar eggs before they hatch.
BT NOW Targets newly hatched and feeding caterpillars after egg hatch.
Monitoring tools Traps and lures can help determine when moths are flying and laying eggs.

Compliance reminder: Always read and follow the current product label. Application rates, target pests, use sites, restrictions, and state registrations may vary.
