Herbicides Calculator

Reduce pesticide and herbicide losses with IITA's herbicide calculator

The "IITA Herbicides Calculator" is a solution designed to address the prevalent issue of pesticide misuse resulting from inadequate calibration of spray tanks. It permits farmers to estimate the required quantity of herbicides for knapsack sprayers. This tool was developed using Java language, the Ionic framework, and Android Studio, ensuring its robustness and usability. Tested for effectiveness and reliability by researchers, this technology assists in calibrating the application of herbicides and other pesticides specifically for knapsack sprayers. It's important to note that the tool does not involve specific compositions or sequences of products or technologies.

  1. Enter Herbicide Dosage:  Input the recommended dosage of the herbicide in liters per hectare as indicated on the herbicide label.
  2. Measure Water Dispensed: Measure the volume of water dispensed on a 10m x 10m plot. (To calculate the water sprayed on a 10m x 10m plot, measure an area of 10m x 10m, equal to 100m². Fill water in your knapsack spray tank and spray the measured area following a straight path at a nozzle height equivalent to your knee level. Enter the volume of water dispensed from your knapsack spray tank onto the 10m x 10m plot.)
  3. Enter Knapsack Tank Capacity: Input the capacity of your knapsack spray tank in liters.
  4. Calculate Herbicide Dosage: Press the "Calculate Volume" button to obtain the precise dosage of the herbicide required to be added to your knapsack spray tank before filling it with water for spraying.
