Quali-Pro Imidacloprid 0.5G is a professional-grade granular systemic insecticide formulated for broadcast application to turf and landscape ornamentals. The active ingredient (imidacloprid 0.5%) is a neonicotinoid that's taken up by plant roots and translocated through the foliage — the result is long-term, root-to-tip protection against soil-dwelling pests like white grubs and against foliage-feeding sucking insects on ornamentals. 30 lb bag is the standard professional pack size, treating roughly 25,000-40,000 sq ft depending on rate.

Active Ingredient + Mode of Action

• Imidacloprid 0.5% — a neonicotinoid insecticide that binds to insect nicotinic acetylcholine receptors, causing paralysis and death
• Systemic activity — granules dissolve into the soil with water; imidacloprid is absorbed by plant roots and translocated through the vascular system into shoots, leaves, and flowers. Insects feeding on any part of the treated plant pick up the active ingredient
• Long residual — a single broadcast application provides season-long control of white grubs (60-90+ day residual against soil-dwelling pests after activation watering)
• Broad-spectrum target list per the EPA label — covers most major lawn / turf / ornamental insect pests
• Inert ingredients 99.5% (granular carrier)
• EPA Reg. No. 53883-321; EPA Est. No. 53883-MO-3

What It Controls

• White grubs (the primary use case) — Japanese beetle, masked chafer, European chafer, May/June beetle, oriental beetle, Asiatic garden beetle, Northern masked chafer larvae
• Mole crickets — for Southern lawns
• Billbugs — bluegrass billbug, hunting billbug
• Annual bluegrass weevil larvae
• Surface-active turf pests — chinch bugs, sod webworms (partial control; use a contact insecticide for active outbreaks)
• Ornamental sucking insects — aphids, scale (soft scale species), leafhoppers, whiteflies, mealybugs on landscape ornamentals when applied to the root zone
• Adelgids on woody ornamentals — hemlock woolly adelgid in particular

When to Apply

• For white grubs (preventive) — apply when adult beetles are flying / egg-laying. Generally mid-June through July in the Northeast / Midwest; earlier in the South. This is the optimal window: granules sit in the soil, dissolve with watering / rainfall, and are in the root zone when grubs hatch and start feeding in August.
• For white grubs (curative) — if grub damage is already visible (irregular brown patches, sod that pulls up like carpet), apply at the higher labeled rate immediately. Effectiveness drops once grubs are large (5th instar).
• For ornamental pests — apply in spring as a soil drench / broadcast around the root zone before pest pressure begins. Allows 2-4 weeks for full systemic uptake.
• Avoid: application during bloom on flowering plants visited by bees, or just before heavy rainfall (runoff risk)

How to Apply

1. Calibrate your spreader for the labeled rate. Standard preventive grub rate is approximately 1.7 lb per 1,000 sq ft (delivers 0.135 oz imidacloprid per 1,000 sq ft). Curative rate is up to 3.45 lb per 1,000 sq ft. Always read the current product label on YOUR bag for exact rate by pest target and turf type.
2. Broadcast evenly with a rotary or drop spreader. Halve the rate and apply in two passes at 90° to each other for the most uniform coverage.
3. Water in immediately — 0.5 in. of irrigation (or a heavy rainfall event) within 24 hours of application is REQUIRED for the granules to dissolve and the imidacloprid to reach the root zone. Without watering, the product sits inert on the surface.
4. Bag coverage: 30 lbs at preventive rate covers ~17,500 sq ft; at the higher curative rate it covers ~8,700 sq ft. Field math: ~25,000-40,000 sq ft total depending on the rate selected.
5. Re-application: a properly-timed and watered-in preventive treatment provides season-long control. Re-treat the following year.

CRITICAL Safety / Pollinator Notes

• Imidacloprid is a neonicotinoid and is highly toxic to bees and other pollinators. This is the single most important safety consideration. Read and follow the label's pollinator protection language exactly.
• Do NOT apply to plants in bloom or to lawns with flowering weeds (clover, dandelion, etc.) actively flowering. Mow off bloom before treatment if necessary.
• Do NOT apply pre-bloom to plants whose flowers will be visited by bees within a window where systemic uptake will still be present in the pollen / nectar at bloom
• Do not allow runoff into water bodies — imidacloprid is highly toxic to aquatic invertebrates and is documented to harm aquatic ecosystems at very low concentrations
• CAUTION signal word — lowest acute mammalian toxicity tier on the EPA label, but the ecological concerns above are independent of the human-health tier
• Some US states (NY, MA, others) have restricted neonicotinoid use on residential lawns or have additional licensing requirements. Check your state's pesticide regulations before purchase / application.
• Wear gloves, long sleeves, long pants, and shoes plus socks when handling the granules. Wash hands before eating / drinking / using tobacco.
• Keep children and pets off treated areas until the granules have been watered in and the surface is dry.
