PESTICIDES APPLICATION TECHNOLOGY PART 1
SPRAY DROPLET FORMULATION
1) ADJUVANT
Material that facilates and modifies the spray formulation to improves performance of pesticides
WHY USE ADJUVANT :question:
reduce drift, evaporation
Improve selectivity or broaden range of control
increase biological efficacy
TYPE OF ADJUVANT
:!!:
SPRAY OIL
-mineral oil, vegetables oil
SURFACTANT
-anionic, cationic, nonionic
2) SURFACTANT
Material that facilates and accentuates the emulsifying, spreading, wetting, or other surface modifying properties
PROCEDURE IN PESTICIDES APPLICATION
CALIBRATION
DECIDE THE APPLICATION EQUIP.
DECIDE THE VOLUME APPLICATION AREA
AMOUNT OF PESTICIDES USED
EVALUATION OF
SUCCESFUL PES. APP :check:
Physical measurement
-no of droplet per given area
-spray deposit
-L/ha
Biological evaluation
-reduce the pest pop.
-yield/ha
Choice of atomizer
aerosol
-fogger
-hydraulic :red_flag: nozzle
-CDA :star:
-Electrostatic spray :fire:
ATOMIZER: HYDRAULIC NOZZLES
FUNCTION
-Meter the value of spray liqid applied
-determine the spray pattern
break spray pattern into droplet
TYPE OF NOZZLE
1)CONE
~Hollow cone
~Variable cone
~Full cone
2) FAN
Standard fan
Even Spray fan
Low Pressure fan
3) DEFLECTOR
INTERNATIONAL COLOUR CODE INDICATE FLOW RATE
