Application Parameters

Crop	Target Pests	Dosage (Rate/ha)	Application Method	Timing
Vegetables	Aphids, whiteflies	100–200 ml	Foliar spray	Early infestation stage
Fruit Trees	Scale insects	100–150 ml	Systemic drench	Active feeding periods
Ornamentals	Thrips, mealybugs	100–150 ml	Foliar spray	Low-to-moderate pest density

1. What is Spirotetramat, and how does it work?

Spirotetramat is a systemic insecticide belonging to the tetramic acid class. It inhibits lipid biosynthesis in pests, preventing the production of essential fats needed for nymph and larval development. This leads to reduced pest populations over time. Its unique bidirectional systemic movement (upward and downward in plants) ensures protection for both new growth and established tissues, even reaching hidden pests on the underside of leaves or within plant structures.

2. What pests does Spirotetramat control?

Primary targets: Aphids, whiteflies, thrips, mealybugs, scale insects, leafhoppers, psyllids.
Secondary use: Effective against diamondback moth larvae in crops like cabbage and broccoli.
Ideal for pests that transmit viral diseases or hide in protected plant areas.

3. What are the key formulations of Spirotetramat?

Suspension Concentrates (SC): 22.4% SC, 24% SC, 240 SC (common for foliar applications).
Oil Dispersion (OD): 150 OD for enhanced plant penetration.
Water-Dispersible Granules (WDG): Suitable for soil treatments or systemic uptake.
Mixed Formulations: Often combined with neonicotinoids (e.g., thiamethoxam, imidacloprid) for broader-spectrum control.

4. How should Spirotetramat be applied?

Foliar Spray: Apply at 100–200 ml/ha (depending on crop) as a fine mist, ensuring complete coverage of leaves (including undersides) and new growth.
Systemic Drench: For soil-borne pests, mix with water and apply to the root zone; absorbed via roots and translocated throughout the plant.
Timing: Use at the early stage of infestation when pest populations are low. Target immature stages (nymphs/larvae) for maximum efficacy.

5. Is Spirotetramat safe for beneficial insects?

Spirotetramat has low toxicity to pollinators (bees, ladybugs) when used as directed, especially when applied during non-flowering stages.
Beneficial insects are less affected due to its mode of action (lipid biosynthesis inhibition), which primarily targets sap-feeding pests.

6. How does Spirotetramat aid in resistance management?

Classified as IRAC Group 23, a unique mode of action not cross-resistant with other insecticide classes (e.g., neonicotinoids, pyrethroids).
Recommended for rotational use with products from different IRAC groups to delay pest resistance development.

7. What is the environmental impact of Spirotetramat?

Low mammalian toxicity: Classified as “low hazard” for humans and wildlife.
Soil and water safety: Moderate persistence in soil (half-life: 10–30 days); avoid overuse in water-sensitive areas.
Bee safety: Safe when applied to non-flowering crops; always follow label guidelines near apiaries.

8. Can Spirotetramat be mixed with other pesticides?

Yes, it can be mixed with:
- Contact insecticides (e.g., bifenthrin) for fast knockdown.
- Systemic fungicides (e.g., mancozeb) for combined disease/pest control.
Avoid mixing with strong alkaline solutions, as they may reduce efficacy.

9. What is the shelf life and storage requirements?

Shelf Life: 2–3 years when stored in a cool, dry place away from direct sunlight.
Storage: Keep in original containers, locked out of reach of children and animals. Avoid freezing or extreme heat.

10. How does Spirotetramat compare to neonicotinoids like Imidacloprid?

Feature	Spirotetramat	Imidacloprid (Neonicotinoid)
Mode of Action	Lipid biosynthesis inhibition	Nicotinic receptor blockade
Target Pests	Sap-feeding insects (aphids, whiteflies)	Sucking pests (aphids, thrips)
Systemic Movement	Bidirectional (up/down plant)	Unidirectional (upward via xylem)
Resistance Risk	Low (IRAC Group 23)	Moderate (IRAC Group 4)
Beneficial Insect Impact	Low (selective)	Higher risk to bees (neurotoxic)
