If the specic weight of the insecticide to be
used is dierent from the ones in the dosing
tables, apply the following formula to calculate
the Kg/ha which are going to be spread:
WHERE:
Z = Kg/ha which are going to be spread.
V = Kg/ha in the table depending on the do-
sing adjustment, the row spacing and the
insecticide’s specic weight shown in the
table
.

= specic weight shown in the ta-

In case to spread insecticide at a dierent
row spacing from the ones in the dosing
tables, apply the following formula:
WHERE:
Z = Kg/ha which are going to be spread.
V = Kg/ha in the table depending on the dosing adjustment, the row spacing and the in-
secticide’s specic weight shown in the table.

6.19 INSECTICIDE MICROGRANULATOR
(OPTIONAL)
In order to adjust the distribution of the insecticide micro
granulator, it is necessary to know the row spacing, the
quantity of product to be distributed per hectare and its
specic weight.
It should be taken into account that there is a wide va-
riety of products, each one with its par-
ticular density and granulometry. There-
fore, precise adjustments are dicult to
achieve.
Micro granulated insecticide is placed
along with the seeds (Fig. 6.129).
