Flite 71 is a widely used non-selective systemic herbicide containing 71% soluble granules (SG) of glyphosate. Developed by Insecticides India Ltd, it’s designed to control both annual and perennial grasses, broadleaf weeds, sedges, and woody plants. Farmers and land managers employ Flite 71 primarily for non-crop areas, such as bunds, fallow zones, irrigation channels, orchards, and plantations. Its potency, versatility, and long-lasting protection make it a staple in weed management practices.
Active Ingredient and Mode of Action
The active substance in Flite 71 is the ammonium salt of glyphosate at a 71% concentration. Glyphosate functions by inhibiting the EPSP synthase enzyme, which disrupts a critical metabolic pathway for aromatic amino acid synthesis. Once sprayed, Flite 71 is absorbed by plant foliage and translocated through stems to roots. This systemic activity ensures the entire weed is affected and leads to root death. Complete plant desiccation usually occurs within 10 to 12 days after application.
Applications of Flite 71
Flite 71 is designed as a post-emergent herbicide, meaning it works after target weeds have emerged. Typical use cases include:
- Clearing weed-infested bunds and irrigation channels
- Managing vegetation on fallow agricultural land
- Weed control in orchards and tea plantations
- Maintenance of non-crop industrial and roadside areas
The herbicide offers broad-spectrum control of problematic species like nutsedge, johnson grass, parthenium, blady grass, and cocklebur.
Dosage and Method of Use
For field applications, common dosage is 8001,200 g per acre mixed in about 175200 L of water.
Benefits of Flite 71
- Highly effective on a wide variety of weeds, including tough perennial species.
- Systemic mode of action ensures control down to the roots, preventing regrowth.
- Non-residual in soil, allowing safe replanting or crop rotation after application.
- Rapid desiccation within 1012 days reduces labor for mechanical weed clearance.
- Lower environmental risk, with low toxicity to birds and aquatic organisms when used correctly.
Safety and Environmental Considerations
Although Flite 71 is considered low in toxicity to bees and wildlife, users must still take precautions :
- Wear personal protective equipment: gloves, goggles, masks, and coveralls.
- Avoid spraying in windy conditions to prevent drift and unintended damage.
- Keep the herbicide away from water bodies to avoid contamination.
- Prevent livestock access to sprayed areas for about 710 days.
Store the product in a cool, dry place away from direct sunlight. Always dispose of empty containers responsibly to minimize environmental impact.
Storage and Shelf Life
Flite 71 should be stored in sealed original packaging in a dry, ventilated area. Products on the market guarantee at least six months remaining shelf life after purchase. Under clear labeling, the typical shelf-life extends to two years.
Limitations and Good Practices
As a non-selective herbicide, Flite 71 will kill any green plant it contacts, so it is unsuitable for crop fields unless used with extreme care. Avoid drift to non-target vegetation. Since plant uptake depends on active growth, dormant or poorly growing weeds may be less susceptible.
To optimize results:
- Apply when target weeds are actively growing and well-leafed.
- Ensure full leaf coverage and avoid spraying shaded or dusty foliage.
- Use properly calibrated sprayers for even distribution.
- Follow label instructions for dosage and wait periods before allowing grazing.
Regulatory Status and Product Alternatives
Flite 71 is registered for use in various countries, primarily for non-crop areas, tea gardens, and orchard weed management.
Flite 71 systemic herbicide, based on 71% glyphosate soluble granules, is an efficient and practical solution for comprehensive weed control in non-crop environments. Its systemic action ensures root-level effectiveness, and its non-residual nature makes it safe for subsequent cultivation. When applied responsibly, it offers rapid weed control, cost savings, and low environmental impact. However, to maintain safety and efficacy, users must strictly follow label instructions, adhere to protective measures, and recognize its non-selectivity. As a component of integrated weed management, Flite 71 is a vital tool for modern agricultural practices.
