The fraction 1/128 represents which method?

• A. 1/32
• B. 1/128
• C. 1/64
• D. 1/256

Answer: (B)

This question is about dilution notation used when mixing a pesticide for spraying. A fraction like 1/128 represents a dilution method, meaning you use a very small amount of product mixed into a large amount of water to make the spray solution. In other words, the final mixture is very dilute because only one part of product is used for 128 parts of water (or for a total of about 128 parts of solution). This approach is chosen for wide, even coverage and to minimize potential plant or environmental impact. If you compared it to other ratios, 1/32 or 1/64 would be less dilute (more product per water), while 1/256 would be more dilute (less product per water). So 1/128 sits in the middle as a specific dilution rate for a spray method.
