Kasumin 2L is an antibiotic/bactericide fungicide used for the control of bacterial diseases in specific fruit crops. The active ingredient is Kasugamycin Hydrochloride Hydrate at 2.3% by weight. It is specifically labeled for use on Cherry (Crop Subgroup 12-12A), Pome Fruit (Crop Group 11-10) such as apple, crabapple, mayhaw, Asian pear, quince, Chinese quince, Japanese quince, and European pear, and Walnut. It controls diseases including Bacterial Blast and Bacterial Canker in cherries, Fire Blight in pome fruits, and Walnut Blight. Application involves spraying the product into the canopy, using outward pointing nozzles at row ends to reduce drift. For most crops, the standard rate is 64 fl oz per acre applied in at least 100 gallons of water per acre. Users must follow specific restrictions, such as not applying after petal fall in certain crops and observing preharvest intervals (PHI) ranging from 30 to 100 days depending on the crop. Handling requires personal protective equipment including chemical-resistant gloves, protective eyewear, and coveralls. It is intended for agricultural use only and should not be used for medical, veterinary, or human purposes.
