1 New technologies for a sustainable pesticide application Training & technology together Prof. Emilio Gil Department of Agri Food Engineering and Biotechnology Polytechnic University of Catalonia Workshop on Pesticide application equipment Novi Sad (Serbia) June 2012 Dose reduction according EU Directive Environmentally use of PPP Operator s safety Other developments for a better use 1

2 Dose reduction according EU Directive Environmentally use of PPP Operator s safety Other developments for a better use Canopy characteristics: key point All the recommended procedures, for both dose expression and volume rate, are based in some canopy characteristic or dimensions: Canopy height (LWA) Canopy width (TRV) Canopy density Leaf surface 2

3 Two options for canopy measurements Simple & Easy Complex & Difficult Q (l/min) x 600 V (l/ha) TRV (m 3 /ha) a (m) x v (km/h) TRD (m 2 /m 3 ) 2 Q (l/min) x 600 V (l/ m ) h (m) x v (km/h) LAI (m 2 /m 2 ) Whatever adopted method must be realistic and directly applicable by the user Canopy characterization Two different methods have been developed for automatic/electronic canopy characterization in order to adapt the volume rate according canopy dimensions The Optimal Coverage Method The Wine Row Volume Method 3

4 Two methods proposed The Optimal Coverage Method DOSAVIÑA, software developed including a wide database on canopy characteristics (Leaf Area), spray typology, pesticide type and weather conditions The Wine Row Volume Method A VARIABLE RATE PROTOTYPE has been developed for a selective application according canopy structure. 4

10 Dose reduction according EU Directive Environmentally use of PPP Operator s safety Other developments for a better use GPS for identify sensible areas 10

11 EDAS - Environmentally Dependent Application System Control drift in orchard sprayers 11

12 Air deflectors Drift control improvements Variation or air section 12

13 Sprayers cleaning system key for environment protection Developments for boom control 13

14 Influence of boom height Optimum boom height: cm Individual nozzle control avoid overlapping The 1 metre part-width section in conjunction with 1 GPS Switch. GPS-Switch reatures savings at operating costs of 3% to 8% compared to the manual switching The reduction of the partwidth sections from 3 metres to 1 metre may result in savings of another 1-2 %! 14

15 Automatic regulation of boom heigth and stability WIĄZKA ULTRADŹWIĘKOW A Automatic control of boom sections and boom heigth 15

16 Nozzle development Continuous changes and improvements Nozzle is responsible of most of the spray quality pattern. In the last years many new developments have been presented in order to improve efficacy and efficiency Air injection nozzles Bigger droplets with the same efficacy 16

17 Doble flat fan nozzles Well adapted for dense canopy to increase penetration (horticulture). Good filter maintenance is required HIGH RISK OF DRIFT due to small droplet size 17

18 Dose reduction according EU Directive Environmentally use of PPP Operator s safety Other developments for a better use 18

19 Sprayers cleaning system key for environment protection Automatic control for sprayer cleaner Independent cleaner pump Less water consume Easy to use Reduced dead volume Easy mixing tank Ergonomic design Extra boom height for maize (Amazone) 19
