Bio – Crys is produced from Bacillus thuringiensis, a naturally occurring bacterial disease of insects. It is ubiquitous in soil and can be used as bio-insecticide. The organism is endophytic in nature and can survive in plants. During sporulation the bacteria produce crystal proteins that have insecticidal activity.
Crops: Banana, Coconut, Turmeric, Sugarcane, Cotton, Paddy, Potato, Cauliflower, Cabbage, Cashew, Beetroot, Carrot, Tea, Coffee, Groundnut, Brinjal, Tomato, Bhendi, Citrus, Onion, Oil seed plants, Flowers, Fruiting plants and trees, Cardamom, Pepper, Blackgram, Greengram, Redgram, Grains etc.
Mode of Action: Upon application in to the field, the bacterium produces spores and secrets crystals of proteins. The proteins are toxic to insects. When insects ingest the Cry - toxins, their alkaline digestive tract denature the insoluble crystals, making them soluble and thus amenable to being cut with proteases found in the insect gut, which liberate the toxin from the crystal. The Cry toxin is then inserted into the insect gut cell membrane, paralyzing the digestive tract and forming a pore. The insect stops eating and starves to
Seed Treatment: Mix 10 ml of Bio-Crys with 1 kg of seeds and moisturize with cooled rice gruel or water and leave it for 30 minutes and sow the seeds.
Root dipping: The root of seedlings should be treated with 1 % solution (10ml/litre) of Bio-Crys for at least 10 minutes before plantation. Prolonged dipping or soaking is acceptable and it will enhance the efficiency.
Soil application: 1 litre of Bio - Crys is recommended per acre. Mix the desired volume with 50 – 100 kg of Farmyard manure or sand and broadcast it in the field. Bio-Crys can also be applied through drip irrigation.
Spray: Foliar and bunch spray can be done. Spray the Bio-Crys at 1.0 – 2.0% concentration (10ml – 20 ml / litre of water) at regular interval of 1 month after transplantation.
Content: Bacillus thuringiensis (2 x 109 cfu / ml)
Dosage: Foliar spray should be done at regular intervals (once in 10 days)
Caution: Do not mix with chemical fungicides or fertilizers.
Expiry: One year from the date of manufacturing
Pack size: 1000ml and 500ml
