Dipotassium phosphite
Based on 1 Customer Validation
Dipotassium phosphite is a phosphite salt and is an antibacterial agent. Dipotassium phosphite directly and indirectly affects development of Phytophthora infestans.Dipotassium phosphite reduces late blight severity in field-grown tomato plants and increases productivity of field-grown tomato plants. Dipotassium phosphite can be used for the research of late blight.

-
Dosage:2.5 mL/L of a 45.8% monopotassium and dipotassium phosphite formulation
-
Administration:foliar; every 7 days (12 total applications)
-
Result:Reduced final late blight severity by 90.01% and area under the disease progress curve for severity (AUDPCs) by 93.11% relative to untreated control plants when applied every 7 days with fungicide rotation.
