While maintaining a constant line source strength and increasing track spacing, the average deposit (upper curve in Figure 5) across the block increases to approach the target application rate. However, with increased track spacing, the variation in the deposit (vertical bars) increases thereby leading to a less uniform deposit within the block. The ratio of the deposit variation to the mean deposit is the coefficient of variation (COV) which minimizes at an optimal track spacing and continues to increase beyond due to the increase in the variation of deposit.
By comparison, utilizing a somewhat larger spectrum (Figure 8) would result in buffer zones between 40 and 80m for varying block sizes. The appropriate receptor representing the specific environmental sensitivity within an area requiring protection and an acceptable off-target deposit are critical in developing actual buffer zones. The level of acceptable deposit will be strongly influenced by the level of protection required, whether it be half the population (LC50) or the whole population (No Observable Effect Level - NOEL).
However, with increased track spacing, the variation in the deposit (vertical bars) increases thereby leading to a less uniform deposit within the block. The ratio of the deposit variation to the mean deposit is the coefficient of variation (COV) which minimizes at an optimal track spacing and continues to increase beyond due to the increase in the variation of deposit. 3 (16) have been suggested as appropriate for deposit variation. Using the optimum track spacing (as given by the track spacing that produces the highest minimum deposit), a composite deposit profile (Figure 6) can be developed from the single swath data set.
