1 IK 12 VC: 7,5 ltr. Tank explanation

2 1. Insecticide manufacturer instructions

3 1. Insecticide manufacturer instructions Insecticide Sachet: SYNGENTA ACTELLIC 300CS Bottle volume: 833 ml. Active ingredient: Pirimiphos-Methyl 30% Active ingredient (Pirimiphos-Methyl) per insecticide bottle:. 250 grm.

4 1. Insecticide manufacturer instructions SYNGENTA ACTELLIC 300CS (833 ml.) Recommended insecticide dosage: apply to 250 m 2 to give a target deposit of 1 grm. of active ingredient per m 2.

5 2. Parameters affecting dossification

6 2. Parameters affecting dossification 1) Concentration of insecticide (tank) 2) Selection of nozzle: most surfaces 80/0.8/3 (8002) 3) Pressure in the nozzle/tank: varies from 3.8 bar to 1.7 bar 4) Distance from the surface: 45 cm 5) Spray speed: 2.5 sec/m

7 2. Parameters affecting dossification DO SPRAYERS MEET THE INSTRUCTIONS GIVEN BY INSECTICIDE MANUFACTURERS? apply to 250 m 2 to give a target deposit of 1 grm. of active ingredient per m 2.

8 2. Parameters affecting dossification HOW to CALCULATE THE DOSSIFICATION IN THE WALL?

9 2. Parameters affecting dossification For calculations: Tank volume Fixed average Fixed Fixed 1) Concentration of insecticide (tank) 2) Selection of nozzle: most surfaces 80/0.8/3 (8002) 3) Pressure in the nozzle/tank: varies from 3.8 bar to 1.7 bar 4) Distance from the surface: 45 cm 5) Spray speed: 2.5 sec/m

10 3. Traditional 10 ltr. metallic sprayers

11 3. Traditional 10 ltr. metallic sprayer Most of these sprayers only have a MANOMETER, but not a REGULATOR. Manometer

12 3. Traditional 10 ltr. metallic sprayer Without Regulator Variation of dossage and droplet size Tank Pressure 3.8 bar 3 bar Flow rate 0,90 l/min l/min. If the pressure varies, the dossage applied on the wall will vary (aprox. 50%) 1.5 bar 0.60 l/min.

13 3. Traditional 10 ltr. metallic sprayer Without Regulator 0.6 l/min 0.75 l/min 0.9 l/min 1.5 bar End 3 bar 3.8 bar Start

14 3. Traditional 10 ltr. metallic sprayer 1. Calculation of the AREA sprayed 1) Tank volume: 10 ltr 2) Flow rate: 0,75 ltr/min Nozzle: 8002 Pressure (average): 3 bar 10 ltr. Spraying autonomy (min.): 10 ltr. / 0,75 ltr./min= 13,33 min.

15 3. Traditional 10 ltr. metallic sprayer 1. Calculation of the AREA sprayed 1) Sprayed band (to a 45 cm): 70 cm 2) Wand speed: sec/m (2 meters in 5 seconds) 3) Spraying autonomy (with 8 ltr. capacity): 13,33 min. (800 seconds) 10 ltr. Area sprayed (m2): 0,70m*800sec/2,25 sec/m= 250 m 2

16 3. Traditional 10 ltr. metallic sprayer 2. Calculation of dossification of active ingredient Start End

17 3. Traditional 10 ltr. metallic sprayer 2. Calculation of dossification of active ingredient Area sprayed with 10 ltr.:.250 m 2 Quantity of active ingredient in the tank:.250 grm. Start Calculation: Dossage of pirimiphos-methyl per m 2 = 250 g. (pirimiphos-methyl)/250m 2 = =1 g./m 2 End 1 grm. (active ingredients) per m2

18 3. Traditional 10 ltr. metallic sprayer 2. Calculation of dossification of active ingredient However: As sprayers don t have a Pressure Regulation Device pressure varies in the nozzle and the flow rate varies So the results varies

19 3. Traditional 10 ltr. metallic sprayer 2. Calculation of dossification of active ingredient End 1.5 bar 0.6 l/min 0.75 l/min 0.9 l/min 3 bar 3.8 bar Start Real results Flow rate (ltr/min.) Dose (g/m 2 ) O,90 1,20 g/m2 0,75 1 g/m2 0,60 0,80 g/m2 20% less

20 3. Traditional 10 ltr. metallic sprayer 2. Calculation of dossification of active ingredient 1,20 gr/m2 Conclusions End 1.5 bar 1,00 gr/m2 3 bar 0,80 gr/m2 3.8 bar 1. Half of the time spraying less active ingredient to the walls Start 2. It can be sprayed less than 20% of the recommended active ingredient quantity
