EBS Alphosides Quinalphos 25% EC Is An Organo-Phosphatic Insecticide That Controls Chewing, Sucking, And Mites Type Pests.

EBS Alphosides Quinalphos 25% EC

1. Product Overview:
Quinalphos 25% EC (Emulsifiable Concentrate) is a broad-spectrum, organophosphate insecticide and acaricide used for the control of chewing, sucking, and soil-dwelling pests in various crops. It acts as a contact and stomach poison, providing quick knockdown and long-lasting residual control. Quinalphos is widely used in agriculture, horticulture, and plantation crops for its effectiveness against caterpillars, borers, aphids, thrips, mites, and leaf miners.

The EC formulation ensures excellent dispersion, enhanced coverage, and penetration, making it highly effective in both foliar and soil applications.

2. Mode of Action:
Quinalphos 25% EC acts through multiple mechanisms, making it highly effective against a variety of pests:

• Contact and stomach poison:

  • When insects come into contact with or ingest Quinalphos, it disrupts their nervous system, leading to paralysis and death.

• Cholinesterase inhibition:

  • It inhibits the enzyme acetylcholinesterase (AChE), which is essential for normal nerve function.

  • This causes the accumulation of acetylcholine, leading to continuous nerve impulses, resulting in paralysis and eventual death.

• Ovicidal and acaricidal action:

  • Quinalphos exhibits ovicidal activity, preventing egg hatching.

  • It is also effective against mites, controlling both larvae and adults.

• Residual activity:

  • Provides long-lasting protection, controlling pests for several days after application.

3. Target Pests:
Quinalphos 25% EC effectively controls a wide range of sucking, chewing, and soil-dwelling pests, including:

• Chewing pests:

  • Stem borers (Scirpophaga incertulas)

  • Root borers (Emmalocera spp.)

  • Shoot borers (Chilo spp.)

  • Leaf folder (Cnaphalocrocis medinalis)

  • Caterpillars (Spodoptera litura, Helicoverpa armigera)

  • Diamondback moth (Plutella xylostella)

• Sucking pests:

  • Aphids (Aphididae)

  • Jassids (Empoasca spp.)

  • Whiteflies (Bemisia tabaci)

  • Thrips (Thripidae)

• Soil-dwelling pests:

  • Termites (Isoptera)

  • Root grubs (Holotrichia spp.)

  • Cutworms (Agrotis ipsilon)

• Mites:

  • Red spider mites (Tetranychus urticae)

  • Yellow mites (Polyphagotarsonemus latus)

  • Broad mites (Tarsonemidae)

• Leaf miners

• Fruit borers

• Diamondback moths

✅ Ovicidal and acaricidal action:
Quinalphos controls all life stages of mites (eggs, larvae, and adults), making it highly effective for mite management in various crops.

  • Repeat applications after 10–15 days, if necessary.

• Method:

  • Use a high-volume sprayer for thorough leaf coverage.

  • Spray evenly on both sides of the leaves, focusing on the undersides where mites and pests hide.

• Pre-Harvest Interval (PHI):

  • Field crops: 21 days.

  • Vegetables: 7–10 days.

• Recommended spray volume:

  • Field crops: 500–1000 liters of spray solution per hectare.

  • Orchards and plantations: 1000–1500 liters of spray solution per hectare.

6. Benefits:

• Broad-spectrum control: Effective against both sucking and chewing pests, including mites.

• Ovicidal and acaricidal action: Kills eggs, larvae, and adults, preventing reinfestation.

• Residual activity: Provides long-lasting protection, reducing the need for frequent applications.
