Details
BT NOW is a water-based, biological insecticide that utilizes a novel strain of bacteria, Bacillus thuringiensis ssp. kurstaki (Btk), to offer targeted control of the caterpillars of certain moths and butterflies on a wide variety of crops. Ingestion of BT NOW paralyzes the insect’s digestive system within hours, halting further crop damage potential. The affected larvae die within 2-5 days.
Active Ingredients: Bacillus thuringiensis ssp. kurstaki strain EVB-113-19
OMRI Listed
- Easy to use liquid formulation
- Four-hour REI — Zero-day PHI
- Low residue — MRL exempt
- Can be used in conjunction with many beneficials and pollinators
- Ideal for IPM programs — Low resistance potential (IRAC GROUP: 11A)
- Tank-mix compatible with many commonly used pesticides, fertilizers and adjuvants
What is BT NOW's mode of action?
The Bacillus thuringiensis ssp. kurstaki (Btk) bacteria found in BT NOW contains natural insecticidal endotoxins called “cry toxins”. When consumed by the larval stage of target lepidoptera pests, these toxins bind to specific receptors in the insect’s gut which immediately disrupts and paralyzes certain digestive functions. After the pest consumes Btk, plant tissue will be protected from further damage as the pest halts all feeding within hours. As the activated toxins disrupt membrane integrity in the caterpillar’s midgut, Btk spores enter the body, proliferate and kill the pest 2-5 days later.
Caterpillar Control in Fall Ornamentals
BT NOW and Trichogramma are two naturally occurring biological organisms that specifically target lepidopotera species and when used together create an effective caterpillar management program. This combination achieves excellent control of caterpillars without harmful residue and without disrupting.
How should BT NOW be used?
Bacillus thuringiensis ssp. kurstaki products have a long history of safe and effective use in agriculture, forestry, and ornamental pest management. When applied properly, Btk products control lepidoptera larvae as well as traditional synthetic chemistries while also preserving beneficial species.
BT NOW is most effective on young, actively feeding larvae. For optimal results, employ early scouting programs to identify target caterpillar infestations and apply at first signs of feeding or when scouting program identifies pest presence. Cover foliage thoroughly to ensure product is consumed by the pest. Repeat applications when necessary to maintain control.
Use Instructions:
The following are general instructions. More complete crop-specific and pest-specific guidelines can be found in the manufacturers under the DOCS tab. Before application, it is recommended that you read and follow those detailed instructions.
BT now is a water-based formulation that can be applied undiluted or diluted with water. Dilution with minimal amounts of water will improve coverage. The amount of water needed for a diluted application will depend on crop size, weather, spray equipment and local experience.
Avoiding spray drift at the application site is the responsibility of the applicator and/or the treatment coordinator. Many factors, including weather conditions and equipment being used, need to be considered to determine the potential for spray drift.
Make applications early in the morning, in the evening, or during overcast conditions for best results. Make sure to apply the product when there is little or no wind. Do not make early morning application if foliage is wet with dew to the point of runoff. Do not make applications when significant rainfall is imminent. BT NOW is more effective when rain is not forecast within 24-48 hours following application. Dry weather will allow larvae to ingest a lethal amount of spray deposits.
MIXING
- Tank mix compatible with many commonly used pesticides, fertilizers and adjuvants.
- Add the specified amount of BT NOW to the required amount of water in the spray tank. Agitate as necessary to maintain suspension. DO NOT store spray mixture in spray equipment for more than 18 hours.
APPLICATION INSTRUCTIONS
- Do not apply through any kind of irrigation system.
- BT NOW must be ingested by susceptible larvae to be effective, so thorough coverage of target foliage where larvae are feeding is essential.
- Apply when larvae are small, newly hatched and actively feeding.
- Repeat applications, according to economic threshold, as necessary to maintain control.
- To improve wetting and distribution on difficult to wet foliage (e.g. crucifers), the addition of a wetting agent is recommended.
- After ingestion, larvae cease feeding within a few hours and death occurs in 2-5 days.
GROUND APPLICATION
Use specified amount of BT NOW (as determined by the chart that can be found on the manufacturer's label under the DOCS tab) in a minimum of 31.25 gallons of water per acre, depending on the type of equipment and crop. This minimum can be lower with ultra-low volume sprayers. Use diluted spray mixtures within an 18-hour period.
AERIAL APPLICATION
Please see manufacturer's label under the DOCS tab.
Not for use on turf being grown for sale or other commercial uses, or for commercial seed production, or for research purposes.
Storage: Do not contaminate water, food or feed by storage or disposal. Store in the original container between 39°F - 68°F to ensure microbial purity and potency. Store container upright and keep it tightly closed when not in use. After extended storage, shake or stir contents to assure a uniform suspension.
