CHOOSING THE IDEAL TRACTOR

PROCEDURE

- Check the sprayer weight in the sprayer's identification plate. - Check the capacity of the sprayer's tank. - Check in the technical specifications table the total power consumption required. Example: - Sprayer weight = 507.15 lb - Tank capacity = 105.68 gallons - Total power consumption = 14.5 HP

1- Considering the power consumption The tractor's engine power must be at least 90% higher than the power required to run the sprayer. Example: - Power required by the sprayer = 14.5 HP - Tractor recommended: with minimun nominal power of 27.5 HP

2- Considering the lift capacity of the hydraulic system The lift capacity of the tractor's hydraulic system must be higher than empty sprayer weight added to the weight equivalent to the tank capacity. Example: - Empty sprayer weight ................ 507.15 lb - Tank capacity ........................... 105.68 gal (approximately 882 lb) - Tractor recommended: with lift capacity of hydraulic system higher than 1,389.15 lb.

ATTENTION The figures above are specifically mentioned in order to direct you on how to proceed to choose the ideal tractor to which you are to mount your sprayer.

OPERATION AND ADJUSTMENTS

SPRAY APPLICATION TECHNOLOGY

A successful spray application does not depend only on a good sprayer or correct use of the chemicals but also on factors to be determined in the field under specialized orientation. Among these factors, some concepts should be part of a criterion of evaluation so that positive results may be attained within the pest control program. - Ideal time - Safety - Sprayer operational condition IDEAL TIME The ideal time for spraying should be chosen according to the chemical product characteristics, as well as to the field conditions: - Infestation level of pests, diseases and weeds; - Infection level of diseases; - Growing stage of weeds; - Weather conditions. SAFETY When spraying your crops, you must make sure there will be no risk to people, animals and environment. Avoid spraying at hotter times, with humidity below 55% or under windy conditions. Do not allow the operator to handle chemicals and spraying machinery without the proper individual protective clothing. CORRECT APPLICATION RATE Any type of application requires that the rate be maintained during the whole spraying work. This will be possible when you have a good sprayer properly calibrated. This calibration can be obtained through practical methods or formulas. Please refer to the section OPERATION AND ADJUSTMENTS - CALIBRATING THE SPRAYER. GOOD COVERAGE You have a good coverage when the whole target is sprayed with uniform distribution, with no risk to the environment and with good results in the pest control. The application rate does not have influence on the treatment results. Therefore good coverages can be attained even with different rates, which may vary according to operational and regional factors. - Application rate - Good coverage - Well trained operator

IMPORTANT! READ CAREFULLY AND FOLLOW STRICTLY THE INSTRUCTIONS ON THE CHEMICALS MANUFACTURER'S LABEL. ALWAYS FOLLOW DIRECTIONS OF A TECHNICIAN WHEN HANDLING AND APPLYING CHEMICALS. ALWAYS MAKE SURE THE SPRAYER IS IN GOOD OPERATIONAL CONDITIONS BEFORE STARTING THE SPRAYING JOB AND EMPLOY A WELL TRAINED OPERATOR. 16

OPERATION AND ADJUSTMENTS

IMPROPER CONDITIONS TO SPRAY: - With strong wind and high temperature. - Against the wind.

1339 1338

PROPER CONDITIONS TO SPRAY - Cooler times of the day, that is, early in the morning or late in the afternoon. - Always with the (light) wind.

SPRAYER CALIBRATION

The safety of people, animals and environment depends on correct spray applications. Therefore, we list below important operational procedures. WHEN HANDLING CHEMICALS - Follow strictly the instructions on the labels. - Use individual protective clothing recommended. - Do not eat, drink or smoke. - Choose a ventilated place. - Wash with water and soap the parts of the body touched by chemicals. WHEN OPERATING SPRAYER - Check for the proper working conditions of the sprayer. - Do not blow by mouth nozzles, valves or tubes. - Do not spray against the wind. - Do not spray at sunny times - Use individual protective clothing recommended. - Do not eat, drink or smoke.

REMEMBER! You are responsible for the success of the application.

PROCEDURE The calibration of the sprayer can be done by calculating the the spray volume through the following formula:

SPRAY VOLUME (gpa)

V=

F . 495 (gpa) S.A

Where: V - Spray volume (gpa) F A S - Total nozzles flow rate (gpm) - Spray swath (ft) - Tractor speed (mph)

NOZZLES FLOW RATE (gpm)

F=

EXAMPLE: Spray volume .................................. 16.035 gpa Spray swath .................................... 82.025 ft Speed .............................................. 2.4856 mph

F=

V x S x A (gpm) 16.035 x 2.4856 x 82.025 (25) F= 495 495

F= 6.605 gpm

ATTENTION The figures shown in the example above are illustrative only. The correct calibration must be done according to the recommendations of technician. 18

OPERATION AND ADJUSTMENTS

DETERMINING THE SPOUT FLOW RATE Different flow rates can be obtained through setting of the flow rate regulating valve, as well as through shifting of dosage unit on the main spout and dosage cell on the auxiliary rotary atomizer.
