Field measurement of spray drift
1 Scope
This standard specifies the method for measuring field crop protection spray drift.
This standard applies to field crops by hanging, towed and self-propelled agricultural sprayer (sprayer spray rod) with shrubs and trees crops
(Including grapes, hops, fruits) with hanging, towed and self-propelled agricultural sprayer (including wind Sprayer).
This standard also applies to hand-held sprayer or aerial spray equipment, but the technical specifications of this standard does not contain these device tests
Detailed program.
Measurements shall be carried out in typical field conditions or outdoor ground prescribed (including grass) on. Available objects include crop spraying spray rod
Fog spray pesticides all field crops and horticultural crops. Test shall be measured and recorded the basic meteorological conditions and crop conditions.
This standard specifies the method for measuring the field away from the test area by a predetermined distance inherent pesticide spray drift produced during the amount of risk in order to achieve
Objective assessment; provides a number of standard measurement distance for the result of the comparison of different tests.
One of drift of the measurement relates to the following two conditions. the amount of spray deposited on the surface level outside the processing area determination or measurement process
Wind distribution of droplet stream transmission within a certain distance measured at area. Deposited on a horizontal plane to evaluate the contamination (such as surface water
Contamination) risks, and distribution of airflow droplet transmission pattern measurements to evaluate the risk of inhalation of droplets of plant structure and field boundary pollution
risk. While the focus may be due to different series of test sample array of choice and different, but the standard is applicable to both cases.
This standard applies to the relative drift between different sprinkler system, if necessary conducted comparison and evaluation of risk, but the reference spray system
EC, the collector, the test site is selected and determined certain requirements related to the possible need to modify. It should be appropriate to describe these modifications.
Measuring the amount of spray drift conditions, should be sprayed as far as possible the amount of deposition on the target area to achieve a spray applied to the actual amount of liquid. because
The drift amount is usually expressed as a direct evaluation of amount of liquid applied at the ratio, and therefore the target drift deposited as part of the process is measured
important.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
The spraying process by the gas flow will bring the amount of pesticide target area.
NOTE. depositing a pesticide on the crop or the ground and then escaping, not for spray drift. Form thereof may be droplet drift, dry particles or vapor, this standard
Sampling and evaluation involves only the droplet drift.
2.2
Field crop spraying operation using spray sprayer rod and trees and shrubs with crops breeze sprayer working width.
2.3
Spraying of the target area.
Basic requirements 3 trials
3.1 General requirements
Spray drift measurements should include the following procedures. a predetermined forward speed along the route to the average wind direction perpendicular to perform one-way spraying, for
