How to calculate the dilution factor of pesticides? Generally speaking, according to the volume, it is assumed that there is 1 liter of pesticide, 1 liter of water is diluted by 1 time, and so on. If the concentration (C) and density (P) of the substance before and after dilution are known, the liquid concentration can be calculated by the formula {(1000*density*concentration)/molar mass=concentration of the substance}, based on the ratio of the concentration. Dilution factor.

How to calculate the dilution factor of pesticide: For example, a bottle of 500 ml of pesticide dilution factor is 1000-2000 times how much water should be added, and 2% of potassium dipotassium phosphate should be added with water (1). Dilution multiple plus water calculation:
500 ml *1000~2000=0.5L*1000~2000
=500~1000 liters (that is, the total amount varies from 500 liters to 1000 liters)
The amount of water added is: 500 liters to 1000 liters - 0.5 liters = 499.5 to 999.5 liters (or kilograms).
(2). Calculate the amount of potassium dihydrogen phosphate added:
2% phosphate fertilizer + 98% water = 100% phosphate fertilizer solution.
