Katyayani Samhar Bt Bio Larvicide Liquid Bio Insecticide

Katyayani Samhar Bt Bio Larvicide Liquid Bio Insecticide

Katyayani Samhar is a biological insecticide containing Bacillus thuringiensis (Bt) in a liquid formulation. It helps control susceptible insect larvae through stomach action. When larvae ingest treated plant material, Bt proteins act in the insect gut, disrupting normal gut function and stopping feeding, which can eventually lead to larval death.

Technical Details

• Trade Name: Katyayani Samhar
• Technical Name: Bacillus thuringiensis (Bt)
• Formulation: Liquid
• Product Type: Biological insecticide / bio larvicide
• Mode of Action: Stomach action through ingestion by susceptible insect larvae
• Primary Target: Susceptible larval insect pests

Key Features & Benefits

• Biological Pest Management: Provides a biological option for controlling susceptible larval pests.
• Stomach Action: Works when target larvae ingest treated plant material.
• Helps Stop Feeding: Disruption of the larval gut can reduce feeding and crop damage.
• Targeted Use: Useful against susceptible caterpillars and other labelled larval pests.
• Integrated Pest Management: Can be incorporated into an integrated pest management programme.
• Liquid Formulation: Convenient for preparing a spray according to label instructions.

Target Pests of Bt Bio Larvicide

• Tobacco caterpillar
• Corn borer
• Stem borer
• Fruit borer
• Pod borer
• Shoot borer
• Rice leaf roller
• Leaf-eating caterpillars
• Cotton bollworm
• Cotton bridgeworm
• Tea caterpillar and tea looper
• Pine caterpillars and spiny moth larvae

Target Crops of Bt Bio Larvicide

• Vegetables: Tomato, brinjal, chilli, okra, cabbage and cauliflower
• Field Crops: Cotton, paddy, maize, pulses, groundnut and soybean
• Other Crops: Use on additional crops only where specified on the product label

Mode of Action

Bacillus thuringiensis produces insecticidal proteins that become active in the gut of susceptible larvae after ingestion. These proteins damage the gut lining, disrupt feeding and can cause larval death. Because the product works through ingestion, good coverage of the plant parts consumed by the target larvae is important.

Application and Dosage of Bacillus thuringiensis

Method of Application

• Measure the recommended quantity and dilute it in clean water according to the product label.
• Spray uniformly over the crop, including the plant surfaces where target larvae feed.
• Apply when susceptible larvae are present, following the recommended crop stage and timing.
• Repeat applications only as directed on the product label.
• Use the product only on labelled crops and against listed target pests.

Precautions of Bt Bio Larvicide

• Read and follow all product-label instructions before use.
• Wear suitable protective equipment while preparing and applying the spray.
• Avoid mixing with chemical fungicides or other products unless compatibility is confirmed.
• Store in the original container under the conditions stated on the label.
• Keep the product away from children, food and animal feed.
• Do not assume the product controls every insect species or larval stage; use only for susceptible target pests listed on the label.
