Tank cleaning between sprays is always important but no more important that if you have been using sulfonylurea herbicides like Rainbow & Brown’s MSF600. Even though this is on the labels it is worth reinforcing this.The sulfonylurea herbicides, like MSF600, have an affinity for binding to plastic tank walls, filters and hoses and then if not clean..

You asked if it’s OK to apply Gibber900  to a paddock grazed 14 days ago. The answer is yes, though the full benefit does take about 18 days or so from application, so to some extent it depends how long before you want to use that paddock again.  If you can wait 18-21 days after you’ve sprayed, it will give you the Full Monty as far as the grass bo..

The Question:  Customer has a blueberry orchard that was planted in March 2017 – The plants are very shallow rooted. They to spray black nightshade and want to know if GA200 would be safe to use (Their sprayer has a hood over the nozzle, so they should not have spray drift, but they are worried about the shallow roots) Is there a possibility that t..

Question:GA200 looks interesting, it seems to be like a broad spectrum glyphosate?If it kills clovers does that mean it also kills gorse and other legumes?  I want to control gorse growing under and around  4 year old alder and poplar trees. I have been cutting the gorse and using MS600  Metsulfuron to spray the stumps, but don't??? want to go too ..

My partner sprayed the gibber  on the paddocks today - he wasn't supposed to do the one the sheep are currently in but did. The instructions say stock should not graze the area for 6 odd weeks so is there a problem and do I need to get the sheep off - they are ewes and lambs A: No need to move the stock, including the lambs. Gibber  has no toxic ef..

QUESTION:Can Gibber growth promoter be applied to very new grass, sown just a month ago?ANSWERDon’t do it.  The Gibber  will definitely damage grass that’s not well developed.  It works by elongating cell growth, which produces more leaf mass.  But the physical structure of the plant has to be strong enough to stand that kind of turbocharging effec..

QUESTION: What rate would you recommend for spraying Decision through a handgun – can you give me a rate per 60 litres?ANSWER:It’s not as simple as it sounds.Decision is normally applied only as an area spray, with a boom or roster sprayer.  So the rate is based on amount of product per unit of area.  That is, for example, 50g per hectare. It’s dif..

Seaweed  Extract Powder This new product was a low-key launch in October 2016. We didn’t make much of a song-and-dance about it, but we knew there were already quite a few fans among our customers for seaweed extract based soil conditioners. And so it has proven:it’s been selling well and getting excellent reviews from users.Seaweed  extract is sui..

MSF600 (metsulfuron-methyl) is NZ’s favourite and most proven chemical for controlling gorse, especially heaps of big gorse.It has a couple of quirks that are the key to understanding why it works like it does.MSF600 suppresses production in the plant of an enzyme called acetolactate synthase (ALS). That enzyme is required to support new growth, bo..

This is just a heads-up. Glyphosate prices will rise, probably fairly sharply, during this calendar year. Not just our brands; everybody’s brands. And it’ll likely be soon.Almost all the world’s glyphosate acid (that’s the technical concentrate used to make usable various forms of glyphosate herbicides) is made in China. And the producers there are..
