is mandatory.
4.2.4 PRELIMINARY WORKS THAN THE
TREATMENT
The Operator shall:
- Makesurethattheconditionsofthecrops,thedevelopment
ofthediseaseortherequirementsofpreventionjustifythe
treatment.
- Makesureof the expectedweatherconditions for allthe
timenecessarytocarryoutthetreatment.
- Avoid, if possible, the spraying in conditions of sensitive
windbecausethesprayedmixturecanbedispersedoutside
thetarget(drift).
Itisadvisabletosuspendthetreatmentwhenthewindspeed
exceeds10Km/h(3m/s).
In the need to operate, we suggest to:
- Increasethesizeofthedrops,thusadjustingtheatomizer
appropriately.
- Checkthatmixtureswithmoreproductsarephysically,che-
micallyandbiologicallycompatiblewitheachother;consult
theSeller/Agent.
- Calculatetheexactamountofproductneededfortreatment
andestablishtheamountofwatertobeusedintheopera-
tion.
- Checkthattheproductisavailableinsufcientquantityto
completethework.
DANGER: Carefully read the instructions for use
in the product containers, to check the conditions
of use, the correct dosage and the deadlines.
4.2.5 QUANTITY OF CHEMICAL PRODUCT TO
BE INTRODUCED IN THE TANK
Referring to the delivery table per hectare, obtain the ne-
cessary parameters to adjust the machine and determine
the exact dose of product to be used for each lling. It is
possibletoestablishthequantityofchemicalproducttobe
insertedinthetank,applyingthefollowingformula:Tank volu-
me x dose/ha: l/ha = quantity of product to be inserted in
the tank. Example:Knowingforexamplethecapacityofthe
tank(i.e.150l),thebaseofchemicalproducttobedispensed
perhectare(i.e.3.5l/ha)isthequantityofliquidtobedistri-
buted(i.e.150l/ha):150 x 3.5: 150 = 3.5 (liters of chemical
product to be inserted in the tank).
