"Joker" is a brand name used for a few different pesticide products.1 To give you an accurate description, I need a bit more information about the specific "Joker" product you're interested in.

It's likely you're referring to one of these two products:

1. Joker Insecticide (Fipronil 80% WG): This is a broad-spectrum insecticide manufactured by Katyayani Organics.2 Its active ingredient is Fipronil 80% WG, making it effective against various sucking and chewing pests in a range of crops.3

• Mode of Action: Fipronil disrupts the insect's central nervous system by blocking GABA-gated chloride channels, leading to uncontrolled nerve activity, paralysis, and death.4

• Target Pests: Stem borers, leaf folders, thrips, aphids, beetles, and diamondback moths.5

• Crops: Rice, chili, grapes, onion, cabbage, and other fruits and vegetables.6

2. Joker Fungicide + Insecticide (Pyraclostrobin 10% + Fipronil 5% SC): This is a combination product manufactured by Gharda Chemicals.7 It contains Pyraclostrobin 10% + Fipronil 5% SC, offering both fungicidal and insecticidal properties.8

• Mode of Action:

  • Pyraclostrobin: Belongs to the strobilurin class of fungicides.9 It inhibits mitochondrial respiration in fungi, preventing energy production and halting fungal growth.10

  • Fipronil: As described above, it disrupts the insect's central nervous system.11

• Target Pests and Diseases:

  • Insects: Yellow stem borer, leaf folder, brown plant hopper, thrips, and fruit borer.12

  • Diseases: Sheath blight, leaf blast, powdery mildew, and fruit rot.13

• Crops: Primarily used in rice and chili.14

To give you a precise product description, please specify which "Joker" product you're interested in – the insecticide with Fipronil only or the combination fungicide + insecticide with Pyraclostrobin and Fipronil.

Once you provide this information, I can give you a detailed overview of its features, benefits, mode of action, target pests/diseases, application methods, and safety precautions.
