Calculating Required
Quantity of Solution
DetermineStep 1: surface area (m2)
Step 2:
Step 3:
In the case of ground crops, multiply the
length of the field by its width.
The required quantity of solution is
calculated as follows:
Refer to the instructions supplied with
the active ingredient to determine:
The surface area of high-growing plants
is calculated approximately by
multiplying the length of the rows by the
average height of the foliage. The result
is multiplied by the number of rows and
then by two if both sides have to be
treated.

:
Required quantity of active
ingredient for 1 hectare (ha) and the
concentration of active ingredient
(mix ratio)
:
Where:
TW = Quantity of active ingredient in l
Multiply the required quantity of active
ingredient for 1 ha by the area
K
= Concentration in %
The area in hectares is obtained by
dividing the number of square meters by
10,000.
determined in Step 1. The result is the
quantity of active ingredient required for
the area to be treated.

Required quantity of solution in l
Example:
Example:
A field 120 meters long and 20 meters
wide has to be treated with a pesticide.
Example:
In Step 2 the quantity of active ingredient
required was calculated to be 0.144 l.
According to the maker’s instructions,
the concentration is 0.1%.
According to the maker’s instructions,
0.4
liters of active ingredient are
Area:
120
m x 30 m = 3,600 m2
3,600 / 10,000 = 0.36 ha
required per hectare to obtain a
concentration of 0.1%.
Quantity of solution:
Quantity of active ingredient:
0.144 l x 100 = 144 l
–––––

0.4
(l/ha) x 0.36 (ha) = 0.144 l
