Shayne 0 3287
Exploring the Potential of Plant Based Amino Acids We have been conducting research and trial work on using plant based amino acids on pasture which we would like to share with our readers.

BOOSTING GROWTH, SAVING COSTS, SUPPORTING SUSTAINABILITY WITH GIBBERELLIC ACID (GA3) We have been supplying gibberellic acid for over 15 years so we have spoken to many people who have asked us if gibberellic acid really works. Gibberellic acid (our Gibb-Gro or Gibber 900) is a plant hormone that was discovered in 1953 and was mainly used on plan..
31 Jul The Second Life of Asulam
Shayne 0 4269
Asulam meets YBG It sounds like another episode in the Harry Potter series but no, it is definitely herbicide-related. Asulam was introduced around 1965 by a company called May & Baker. Some of us oldies will no doubt remember them. It’s a carbamate-based herbicide with a mode of action being a DHP inhibitor. Its primary target weeds are docks an..

21 Feb Spraying Driveways and Waste Ground
Shayne 0 10720
My personal opinion... When I was spraying my driveway at home I got fed up with respraying, and although being a manufacturer where I get herbicides very cheaply, I decided to go and buy a competitor product called TAG G2(1) that you can get from most Farm supply stores.   I gave up on this as although TAG G2(1) is a very good product containing..
12 Feb The ABC of Ragwort Control
Shayne 0 5119
The ABC of Ragwort Control Ragwort is not a weed that lets you get away with a spur-of-the moment approach.   There are two reasons for that.  First is that this normally biennial plant has the ability to morph into a very hard-to-kill multi-crown perennial if it’s been mowed, slashed or ineffectually sprayed.  And each mature plant can produce 2..
17 Jan Unlocking the Secrets of Soil: A Beginner's Guide to the Art of Soil Conditioning
Shayne 0 3795
Unlocking the Secrets of Soil: A Beginner’s Guide to the Art of Soil Conditioning   Generally, improving soil depends on the Cation Exchange Capacity (CEC) of the soil that you are working with. Exchange capacity is merely a measure of the capacity of the soil to exchange nutrients.   Whether the CEC is large or small, it affects the soil’s cap..
12 Sep Does Water Quality Affect Herbicides?
Shayne 0 11009
Does Water Quality Affect Herbicides? A simple question and a resounding yes.  For instance, most of you know that some herbicides, glyphosate being one of them, lose activity in the soil but that also applies to soil particles in the water.  So if you are dragging water from a pond, even if you are filtering you need to be careful that the filter..

25 May Controlling Weeds in New Pasture
Shayne 0 9147
Controlling Weeds in New Pasture This one can be tricky as many of the herbicides used for general weed control in established pasture are just too tough on new pasture and you risk damaging your new pasture. Whether grass weeds or broadleaf weeds they can be either annual or perennial. It is really important that you are on top of perennial weed..
10 Jan How Long Does it take for Herbicides to Kill Weeds
Shayne 0 38804
How long should it take stuff to die, after you’ve sprayed it?     It depends on three things.   First is the species, size and maturity of the weed involved.  Fast growing species, especially annuals, will die quickly because the herbicide is transported right through their smaller and simpler structures very quickly. Older, larger, and more ma..

05 Aug How to Kill Californian Thistle in Pasture NZ
Casey 0 224
Californian thistle is hard to kill because the plant you see is only the top of a deep, spreading root system that keeps throwing up fresh shoots from root buds. Knocking back the top growth won't get on top of it. The reliable approach is a herbicide that moves through the whole plant down to the root buds, applied while the thistle is actively..
05 Aug Grass stopped growing? It's just idling, not done
Casey 0 292
Grass growth stalls once soil temperatures drop below about 10 degrees, which is the winter feed gap every farmer knows. Gibberellic acid, a natural plant hormone sold as Gibb-Gro and Gibber900, can get pasture moving again once soils sit in the 6 to 13 degree range, with a lift in dry matter over about three weeks. It works as a top-up on green,..
