Acetamiprid 20 SP is a systemic neonicotinoid insecticide used mainly against sucking and piercing insects.

• 20 SP = 20% active ingredient in Soluble Powder form
• Chemical group: Neonicotinoid
• Highly effective for aphids, whiteflies, thrips, jassids, leaf miners
• Widely used in vegetables, fruits, cotton, ornamentals, and commercial farming

Benefits in Gardening

A) Excellent control of sucking pests

It works exceptionally well against:

• aphids
• whiteflies
• thrips
• jassids
• leaf hoppers
• mealybugs
• leaf miners
• psyllids

These pests cause:

• curling leaves
• yellowing
• stunted growth
• poor flowering
• fruit drop
• virus transmission

Acetamiprid helps prevent all of these.

B) Systemic action

After spraying, the plant absorbs it through leaves and stems.

It then moves through plant sap (xylem/phloem tissues), so insects die even when feeding on hidden plant parts.

C) Long residual protection

Usually provides 7–14 days protection, depending on rain, crop type, and pest pressure.

D) Fast knockdown

Visible pest reduction often starts within 6–24 hours.

E) Better crop yield

By reducing sap-sucking insects, plants maintain:

• better photosynthesis
• better flowering
• improved fruit set
• higher production

General Application Rate

The most common agricultural recommendation:

Per liter of water

0.25–0.5 gram per liter

For 15-liter knapsack sprayer

4–8 grams per 15 liters

Per acre

Usually 20–40 grams per acre

Can vary by crop and infestation severity.

Best Method / Practice to Use It:

Best spraying time

Spray during:

• early morning
• late afternoon / evening

Avoid strong sunlight.

Spray technique

Spray both:

• upper leaf surface
• lower leaf surface

This is extremely important because whiteflies and aphids stay underneath leaves.

Mixing method

1. Fill sprayer half with water
2. Add measured powder
3. Mix thoroughly
4. Fill remaining water
5. Spray immediately

Best practice

Use a spreader/sticker for better adhesion.

Precautions During Application

Important safety measures:

• wear gloves
• use face mask
• wear long sleeves
• avoid skin contact
• avoid inhalation
• do not eat or smoke during spraying
• wash hands after use
• keep away from children
• keep away from ponds/fish tanks

Acetamiprid is toxic to beneficial insects, especially bees during flowering.

Chemical Formula

C₁₀H₁₁ClN₄

Chemical Contents Present

For 20 SP formulation:

• Acetamiprid = 20%
• inert carriers / wetting agents = 80%

if stored in cool and dry conditions in sealed pack.

How It Is Made / Produced

Produced by synthetic organic chemistry.

Main industrial steps include:

• chloropyridine ring synthesis
• cyano group addition
• amidine functionalization
• crystallization
• soluble powder formulation

Then blended with:

• dispersants
• wetting agents
• anti-caking fillers

This creates SP powder.

Other Uses Apart from Gardening

• commercial agriculture
• fruit orchards
• tea gardens
• cotton fields
• ornamental nursery plants
• domestic pest control
• flea control in pets

Biology Behind Pest Elimination

Biologically, insects depend on nerve signal transmission.

Acetamiprid binds to insect nerve receptors called:

nicotinic acetylcholine receptors (nAChRs)

This causes:

• continuous nerve stimulation
• paralysis
• feeding stop
• death

The insect usually stops feeding very quickly.

Chemistry Behind Pest Elimination

Chemically, it acts as a nicotine mimic molecule.

It behaves similarly to nicotine in insects.

It binds strongly with receptor proteins and is not easily broken down immediately.

This causes:

• sodium channel imbalance
• persistent depolarization
• nervous system collapse

Result:
rapid paralysis and death
