16.2. Calculation of the required plant protection agent/spray
The required quantity of plant protection agent for the intended
purpose is stated in the instructions for the plant protection
agent.
The surface area is generally stated in hectares (ha).
The required quantity for the area to be treated can be calculated
in 2 ways:
Variant 1: Calculation of the required plant protection agent quantity in kg
Required quantity of agent
(kg)
=
recommended quantity (kg/ha)
x
area
(ha)
Sample calculation
based on the following data:
Recommended quantity:
2
kg/ha
Surface area to be treated:
70 a
Area converted to ha
0.7 ha
Calculation:
2 x 0.7 = 1.4
The required quantity is 1.4 kg for 70 a
Variant 2: Calculation of the required quantity of water in l
Required water quantity
(l)
= recommended water quantity (kg/ha)
x
area
(ha)
Sample calculation
based on the following data:
Recommended water quantity:
400 l/ha
Surface area to be treated:
70 a
Area converted to ha
0.7 ha
Calculation:
400 x 0.7 = 280
The required water quantity is 280 l for 70 a
