Product Type: Insecticide
Brand Name:
GSP

Product Overview:

Topkill is a selective, post-emergence herbicide containing Tembotrione 34.4% SC. It is used in maize crops to control a broad spectrum of both broadleaf and grassy weeds. It works systemically and is highly effective at low application rates.

Summary:

Feature Details
Mode of Action 4-HPPD inhibitor - blocks carotenoid synthesis → chlorophyll bleaching → weed death
Crop Maize (corn)
Target Weeds Broad-leaf weeds and grassy weeds (e.g., Echinochloa spp., Trianthema portulacastrum, Brachiaria spp.) 
Application Timing Post-emergence of weeds; often when weeds are at 2-5 leaf stage (or early growth)
Dosage (approximate) ~114-115 ml/acre for maize (varies by product/brand) 
Water Volume / Acre ~200 L per acre for spray dilution (varies) 
Waiting Period / PHI ~55 days (for maize) in some formulations. 


Benefits:

  • Broad-spectrum control: It kills a wide variety of chewing and sucking insects that damage crops, including bollworms, fruit borers, aphids, and jassids.
  • Fast action: As a neurotoxin, it acts quickly on the insect's nervous system, causing rapid paralysis and death.
  • Dual action: The insecticide works through both contact (killing pests that touch the treated surface) and stomach action (killing pests that ingest treated foliage), ensuring higher efficacy.
  • Higher yields: By effectively controlling pests, Topkill helps protect crops from infestation, leading to healthier plants and better yields.
  • Cost-effective: Its high efficacy and broad-spectrum control mean that lower application rates can be effective, making it an economical choice for farmers.
