What does the suffix '0.5G' indicate in a granular pesticide label?

• A. Granular with 0.5% active ingredient
• B. Granular with 5% active ingredient
• C. Gel pesticide with 5% active ingredient
• D. None of the above

Answer: (A)

The designation 0.5G tells you two things about the product: its form and its concentration. The G means it’s a granular formulation—the material comes as dry granules to be spread where needed. The 0.5 before the G is the active ingredient concentration by weight, specifically 0.5%. So for every 100 units of product, 0.5 units are the active ingredient and the remaining 99.5 units are inert filler and carriers. In practical terms, that’s 0.5 grams of active ingredient per 100 grams of product (or 5 grams per kilogram). It’s not a gel formulation, and it’s not 5% AI, so that higher concentration wouldn’t fit this label.
