What makes a good knapsack sprayer?

Circular Head Landcare Group have used their LAP grant money to put towards a new, non-leaky knapsack for ricegrass spraying.

Circular Head Landcare Group (CHLG) focus a lot of their attention on battling ricegrass infestations in Duck River and surrounds.  Ricegrass is an invasive species which colonises mudflats and estuaries by clogging channels and destroying habitat. They take utmost care in the timing of spraying and chemicals used to ensure it is safe for the riverine environment. Good equipment for the job is a must, and CHLG are pleased to announce their purchase of new, quality knapsacks making their lives a lot easier.

  • wand clamp for travel and storage
  • stable base 
  • clear markings of contents for mixing

  • Will the sprayer do the job I need? Ensure your knapsack sprayer is suitable for the types of plants you will be spraying, the terrain you will be navigating, and the water and chemicals you will be using. 
  • Is the pressure appropriate for your job?
  • Is your sprayer safe to lift? Is it stable on on solid ground? 
  • Is it easy and safe to fill, and have clear markings for chemical mix?
