Starthene is a broad-spectrum insecticide that's been a popular choice among farmers for many years.1 It's known for its quick knockdown action and effectiveness against a wide range of sucking and chewing pests.2 Here's a detailed description:

What it is:

• Contact and systemic insecticide: Starthene works both through contact, meaning it needs to directly touch the pest to be effective, and systemically, where it's absorbed by the plant and transported within its tissues.3

• Organophosphate: It belongs to the organophosphate class of insecticides, which are known for their broad-spectrum activity and fast action.4

• Versatile application: It can be used on a variety of crops to control various pests.5

Active Ingredient:

• Acephate 75% SP (Soluble Powder)6

Mode of Action:

Starthene works by inhibiting the enzyme acetylcholinesterase (AChE) in the nervous system of insects.7 This enzyme is crucial for breaking down the neurotransmitter acetylcholine, which is involved in nerve signal transmission.8 When AChE is inhibited, acetylcholine builds up, leading to overstimulation of the nervous system, paralysis, and ultimately death of the pest.9

Target Pests:

Starthene is effective against a wide range of pests, including:

• Aphids: Small, soft-bodied insects that suck sap from plants.10

• Jassids: Sap-sucking insects that can cause leaf curling and yellowing.11

• Thrips: Tiny, slender insects that cause damage by sucking sap from leaves and flowers.12

• Whiteflies: Small, winged insects that suck sap and can transmit plant viruses.13

• Caterpillars: Larvae of moths and butterflies that feed on leaves and other plant parts.14

• Bollworms: Larvae that bore into cotton bolls, causing significant damage and reducing yield.15

• Stem borers: Larvae that bore into the stems of plants, disrupting nutrient transport.16

• Leaf folders: Larvae that fold leaves and feed inside, protected from contact insecticides.17

Crops:

Starthene is registered for use on various crops, including:

• Cotton18

• Paddy (Rice)19

• Vegetables (Tomato, Brinjal, Okra, etc.)20

• Fruits

• Cereals21

• Tobacco22

• Sugarcane23

Benefits:

• Broad-spectrum control: Effective against a wide range of sucking and chewing pests.24

• Fast action: Provides quick knockdown of pests.25

• Systemic action: Offers some protection from within the plant, reaching pests that may be hidden.26

• Ovicidal action: Can also kill eggs of some pests, preventing future infestations.27

• Cost-effective: Generally an affordable insecticide option.28

How to Use:

• Dosage: The recommended dosage is generally 350-500 grams per acre.29 However, always refer to the product label for specific recommendations for your target crop and pest.

• Application: Apply Starthene as a foliar spray, ensuring thorough coverage of the plant, especially the affected areas.30

Important Notes:

• Safety First: Starthene is an organophosphate insecticide, so it's important to handle it with care.31 Wear appropriate protective clothing when handling and applying the product.

• Environmental Considerations: Follow the instructions on the label to minimize environmental impact.

• Resistance Management: Rotate Starthene with insecticides from different chemical classes to prevent the development of resistance in pests.

• Storage: Store the product in a cool, dry place away from direct sunlight and heat.
