Group 3 Herbicide

Indigo ProForce Checkpoint 500SC Herbicide is a selective herbicide containing 500g/L of the active ingredient Propyzamide. It is specifically registered for the pre and postemergent control of Winter Grass (Poa annua) in established turf, with excellent safety on a range of warm season turf varieties. The low application rates and high active ingredient loading make Checkpoint 500SC Herbicide a useful economical and an effective option for Winter Grass control. Offers a shorter term residual pre-emergent option for Winter Grass, with early and midseason applications most effective.

 

Key Features

  • Offers pre & early post-emergent control, ensuring you can’t miss the application window.
  • Offers a shorter-term residual pre-emergent option for Winter Grass, early and mid season. Defined residual period of 6-8 weeks allows flexibility around overseeding / renovation operations.
  • Useful resistance management rotational tool. Reduces reliance on Group 3 chemistry.
  • Root absorbed herbicide. Can be irrigated into the rootzone and still be effective, reducing tracking concerns.
  • Effective in cooler conditions. Unlike SU chemistry, Checkpoint 500SC can be used successfully in winter.
  • Excellent tolerance to warm season grasses. Reliable on warm season turf.
  • Reliable SC formulation. Easier to measure and add to the tank, whilst having useful tank mix flexibility.

 

Maximising Performance:

  • Checkpoint 500SC is most active in coarse to medium textured soils of low organic matter and relatively inactive in peat or muck soils or mineral soils high in organic matter content. Herbicidal activity is best in soils containing less than 4% organic matter. Use in soils with higher organic matter may result in inconsistent or incomplete weed control.
  • Apply during the autumn and winter, if established turf is infested with seedling Winter Grass. Mature Winter Grass plants become more difficult to control, with bio-type differences also impacting on the performance that can be achieved.
  • Ensure a uniform coverage. Irrigate immediately after application with 12-25mm irrigation or rain and again 24 hours later. Repeat treatment if necessary on Queensland Blue Couch after 4 weeks.
  • Checkpoint 500SC breaks down more rapidly in warmer soils. The cooler the soil, the longer the residual control that can be achieved. A drop in soil temperature of 100C, roughly doubles the half-life of propyzamide.
  • Soil moisture is important as Checkpoint 500SC is only absorbed by roots, with no foliar uptake. Without sufficient moisture in the soil, Checkpoint 500SC cannot be taken up by the target weeds.
  • Do not reseed for 60 days after treatment.
  • Use only on established turf.
  • Do not use on Bluegrass, Ryegrass, Fescue or Bent Grass Turf.
  • To enhance herbicide movement into the soil, it is recommended that Checkpoint 500SC be tank mixed with a suitable soil surfactant. Hydrophobic soil conditions can impact upon performance.

Mode of Action

Checkpoint 500SC is a soil acting, residual herbicide. It’s active ingredient, propyzamide, is readily absorbed by the weed’s root system. It works largely by preventing cell division. Checkpoint 500SC actively restricts cell division by preventing proteins required for spindle fibre production in a process called mitosis. Spindle f ibres are critical in transferring DNA to new cells in the cell division process. As a result, Checkpoint 500SC applications prevent spindle fibres from forming, resulting in the prevention of cell division, leading to a limitation of growth and eventual weed death of susceptible plants. Control may only take a matter of weeks in good growing conditions. However, it can take months where plant growth is limited by temperature and light.

Brings history to life
Format: Paperback
Got this book as a read aloud before traveling to London. We did a tour of the Tower of London and used the map in this book, marking off the different parts we walked theough- talking about which parts were the setting of different scenes in the book. Reading this gave my kids a real love and personal connection to the Tower. Cliffhanger endings to different chapters. My 9 and 6 year old lived it. My 4 year old couldn't keep up.

Accessible, fun, and exciting.
Format: Kindle
While this book is aimed at younger readers (it includes, for examples, expletives like "Zooks!" and "Zounds!"), I Escaped The Tower of London is a neat historical fiction novella with taught pacing that readers of all ages can enjoy. Using the real-life account of John Gerard as inspiration, the authors have created a young boy who escapes from the Tower of London while attempting to aid Princess Elizabeth during Queen Mary's reign. It's exciting, it fast-paced, and it even has a pleasant message about doing the right thing — even when the right thing is hard to do. It's packed with a hodgepodge of images (most of them public domain, but also a few original pieces) that add to the experience. And the end includes a brief lesson on the historical figures involved. Despite the source material, you shouldn't worry if you (or your young ones) are squeamish; the main character sidesteps the torture and there's very little violence. All in all, quite a good read. Very accessible, surprisingly fun and exciting.

Loved it!!
Format: Paperback
I have bought all of the books in this series for my nephew and he LOVES them. I get an email whenever a new one is coming out and I can buy it (which I always do) if I would like. It makes it so easy to keep current on the series.

wow!
Format: Kindle
What an amazing story that tells about history from the perspective of a kid named Ben that was pretty much forced (but was thankful for the work) to work with coal in the Tower of London, to find out Princess Elizabeth was arrested and sent to the same tower. The plot thickens as he helps her escape. He was met with many challenges, but his best friend Tim helped him always, what a faithful friend! I absolutely love and adore this story because it’s based on history and real life facts, these things actually happened! But when you read it, the author has written it so well it almost sounds like a fantasy! I can’t wait to read more, it’s such a great book, I give it 5 stars but really it deserves 10! Highly recommend!
