Mahindra Summit Grumman Herbicide — Glufosinate Ammonium 13.5% w/w SL

Grumman by Mahindra Summit Agriscience Limited is a high-performance, non-selective, post-emergence contact herbicide. Powered by Glufosinate Ammonium 13.5% SL, it acts as a highly effective shield against a broad spectrum of annual and perennial weeds, including hard-to-kill grasses, sedges, and broadleaf weeds. It works through a unique contact action that quickly destroys weed cells without leaving harmful long-term residues in the soil, ensuring clean fields and better crop yields.

Technical Specifications:

• Brand Name: Grumman
• Manufacturer: Mahindra Summit Agriscience Limited
• Active Ingredient: Glufosinate Ammonium 13.5% w/w
• Formulation Type: SL (Soluble Liquid) — Highly water-soluble
• Category: Herbicide / Weedicide

Key Features & Benefits:

• Broad-Spectrum Weed Control: Destroys both grassy and broad-leaved weeds in a single application.
• Fast-Acting Formula: Shows visible wilting and yellowing symptoms on weeds within 2 to 4 days, with complete weed knockdown in 7 to 12 days.
• Safe for Environment & Soil: It has a very short soil life as it breaks down easily upon touching soil particles, leaving no toxic residue for the next crop.
• Excellent Resistance Management: Features a unique mode of action making it highly effective against weeds that have developed resistance to regular glyphosates or other herbicides.
• Chemical Mower Action: Kills only the green parts of the weed it directly touches, making it safer to use around tree trunks or row crops using a protective hood.

Target Crops & Target Weeds:

• Recommended Areas/Crops: Tea gardens, Cotton fields, Sugarcane, Fruit Orchards, and all Non-Cropped Areas (open plots, bunds, fences).

Dosage & Application Guide:

• Standard Dosage: 1000 ml to 1200 ml per acre (or approx. 6-7 ml per litre of water based on weed density).
• Water Volume: Thoroughly mix the dosage in 150–200 litres of clean water per acre.
• Application Stage: Spray when weeds are young, actively growing, and roughly 4 to 6 inches in height.
• Nozzle Type: Use a Flat-Fan or Flood-Jet nozzle with a protective spray hood to prevent drift onto main crop foliage.
• Best Practice: Ensure a minimum rain-free period of 6 hours after application for maximum chemical absorption.
