Select one of the proposed types. Sprayer determines the efficiency of the application. See the efficiency value for different types of sprayer in the section DOCUMENTS from the home page.

Once the choice is made, sprayer is qualified by a colour depending on its efficiency.

The plant density is calculated from above values using the following expression: 10000 / (tree spacing * row spacing).

Leaf area index (LAI) is a dimensionless value defined as the one-sided green leaf area per unit ground surface area (ha/ha). Its value is estimated from the row spacing, the canopy height, the crosswise mid-width of canopy and the growth stage. In the section DOCUMENTS from the home page is a document which explains the procedure for the calculation of the LAI from the aforementioned parameters.

Enter the maximum capacity of the main sprayer tank in litres (no decimals).

Select the option better representing the orchard.

Enter a commercial name or active ingredient or registration number (only authorized in Spain).

Enter the dose value and select the dose expression system: "(%) concentration", "product (kg or L per ha)", o "kg or L per 10.000 m2 de leaf wall"

Forward speed

DOSA3D determines the dose assuming that forward speed is necessarily in the recommended range. Forward speed upper recommended values can reduce the pesticide deposition mainly in the canopy internal zone.

Recommended forward speed

Fruits and grapes: 5.0 km/h (max. 7.0 km/h)
Almonds and olives in hedgerow: 5.0 km/h (max. 7.0 km/h)
Citrus: 1.5 – 3.0 km/h (max. 5.0 km/h)
Isolated trees (olives in goblet): 2.0 – 3.0 km/h (max. 5.0 km/h)

Weather conditions

DOSA3D determines the dose assuming that weather conditions are necessary for the following recommended ranges:

Temperature: 10-20ºC (never spray at less than 5ºC and upper 30ºC)
Humidity: 35-80% (never spray in rain or fog conditions)
Wind speed: lower than 1 m/s (never over 3 m/s or in the direction of risk areas as residences, routes, and surface waters)
