Krosin AG is a broad-spectrum bactericide that consists of Streptomycin sulphate 90% + Tetracycline hydrochloride 10% SP. Krosin AG is a bactericide that cures already infected crops through systemic and curative action. This bactericide inhibits bacterial protein synthesis, helping stop further spread of bacterial diseases. It is effective against a wide range of diseases like leaf spot, stem canker, leaf blight, and other diseases.
Key Features and Benefits of Krosin AG Bactericide:
Healthy Harvest: Krosin AG controls bacterial diseases on various crops, promoting healthy crop growth and successful harvest.
Dual-Action Formula: The Streptomycin Sulphate 90% + Tetracycline Hydrochloride 10% SP chemical composition works together and provides contact and systemic action against harmful diseases.
Long-Lasting Protection: Streptomycin Sulphate 90% + Tetracycline Hydrochloride 10% SP is absorbed by the crops through systemic action, offering continuous protection.
Versatile Application: Krosin AG bactericide can be applied through various modes, including foliar spray, seed treatment, and root treatment.

How to Use Krishi Rasayan Krosin-AG Bactericide:
Open the Krosin AG pack carefully and measure the required quantity using a clean spoon or weighing scale.
Wear gloves and a face mask before measuring the product.
Half-fill the spray tank with clean water.
Slowly add the measured Krosin AG into the tank while stirring continuously until fully dissolved.
Add the remaining water and mix thoroughly to form a uniform spray solution.
Use a fine-mist or hollow-cone nozzle for proper coverage.
Spray during calm weather, covering both upper and lower leaf surfaces.
For seed treatment, prepare a slurry with Krosin AG and water and coat the seeds evenly before sowing.
Best Time to Apply:
Spray Krishi Rasayan Krosin-AG Bactericide at the first sign of bacterial disease symptoms — small water-soaked spots on leaves, wilting of shoots, or bacterial ooze from stems. Early spraying gives the best results because bacterial diseases spread quickly once established. Late afternoon or early evening is the best window, as leaf temperature is cooler and product absorption is stronger.
Frequency of Application and Re-entry Period:
Frequency: 2 to 3 sprays of Krosin AG per crop cycle at 10 to 15-day intervals, depending on disease pressure and weather.
Re-Entry Period: Wait 12 to 24 hours after spraying before re-entering the treated field without protective clothing.
Compatibility: Krosin AG is compatible with most common insecticides, fungicides (especially copper-based products), and water-soluble fertilizers. Rotating Krosin AG with copper fungicides gives better bacterial control and slows down resistance build-up. Always run a small jar test before a new tank-mix.
Safety, Precautions and Handling:
Wear full protective clothing including hand gloves, face mask, and goggles before handling.
Avoid eating, drinking, and smoking during the entire mixing and spraying operation.
Spray only in calm weather conditions to avoid drift and inhalation.
After application, change clothes and take a bath with soap and clean water.
