ANNEX 2-A
ASSUMPTIONS FOR CALCULATIONS OF PESTICIDE/FUNGICIDES
APPLICATION RATES AND COSTS
Basically, there is no conventional way to calculate pesticide/fungicide
costs for a particular area of production of a particular period of time. It
depends on how many pesticide/fungicide applications you need for a particular
product (flowers) and what kind of pesticide/fungicide might be needed. This
information can be found in any technical reference for flowers. However, for
roses, carnations, and gladiolus you may use the following norms under normal
production conditions (no heavy infestation). This information was collected
from growers in the Chott Meriem area.
Roses
Pesticides or
Disease Fungicides Used Number of Applications
Oidium Triforine 3-4/year
Mildion Man~be 2-3/year
Botrytis Vinchlozoline 2-3/year
Perimor
Pucerons Verts Dimethoate 3-4/year
One application needs 80 to 10U hectoliters of solution
(pesticides/fungicide quantity + water) per hectare. One hectare usually
consists of 18 or 20 green houses. Therefore, the quantity of any
pesticide/fungicide needed for hectare is:
e.g.:
and,
100 times the number of grams/hectoliter needed
Given a solution of Perimor of 10 grams/hectoliter
an application rate of 100 hectoliters per hectare for one
application, then 1 application/hectare needs 100 x 10 grams
= 1000 grams = 1kg of perimor
The costs/application/hectare is 22 DT for Perimor which cost 22DT/kg.
If roses need 3 to 4 application of Perimor/hectare/year, then total costs
per year per hectare would come to 88 DT/ha/year.
