Question: GA 200 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 MS 600 Metsulfuron to spray the stumps, but don???t want to go too close to the trees with that as I think it could damage the trees by being taken up by the tree roots? Another option may be to use glyphosate but perhaps GA 200 to spray the stumps would be better? - what rate do you reckon? Answer: GA200 is fairly close to glyphosate in its kill spectrum with the exception that it is also effective against clover.  That does mean ..

Is there a withholding period for Gibber

Q:  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 effects at all.  There’s no withholding period required from a stock safety point of view.   All the references on labels and literature to not grazing within such-and-such number of days after applying Gibber are simply to let the stuff do its job and produce heaps of new lush growth.  This process usually takes about 3 weeks from spraying to ..

QUESTION: Can Gibber growth promoter be applied to very new grass, sown just a month ago? ANSWER Don’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 effect, and new grass isn’t strong enough.  It will elongate, then literally fall over because it’s not strong enough to support the extra mass, and will be ruined. The label says don’t apply to pasture until it’s 12 months old.  That could be a bit conservative; maybe 7-9 months would be OK if the grass is doing very well and you have tested a small area first to..

What rate would you recommend for spraying Decision through a handgun?

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 difficult to give a rate per unit of water for handgun spraying, unless 1 know for how much area is covered by that operator using that handgun with each 100L of water.  Did Malcolm say how much area he would spray with 100L water?  Or with however many litres of water his handgun spray tank holds? It becomes even worse when I say that Decision has ..

Glyphosate Prices on the Move Again

Glyphosate Prices on the Move Again

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 constantly having to juggle with all sorts of commercial and Governmental issues that affect the cost of making the stuff. It’s happening again right now. This time it’s because production of a couple of substances used to make glyphosate acid has been curtailed, partly because of some new Chinese regulations (essentially, too much industry in certain overlyconcentrated areas), and partly ..
