John Mc starts with ... Does anyone have a favourite supplier of the above mentioned chemical in Australia? There is a good source in the USA, namely http://www.jlhudsonseeds.net/GibberellicAcid.htm Some Googling research tells me that it is virtually a must to get our Myrica Rubra seeds to germinate. Any help would be greatly appreciated. | About the Author JohnMc1 Warnervale NSW 6th September 2012 4:00pm #UserID: 2743 Posts: 2043 View All JohnMc1's Edible Fruit Trees |

Speedy says... yeah, ProGibb is available as a box of 10 sachets of 2.5g at 400g/kg. for use on agricultural crops (thinning and/or increasing fruit size of grapes , cherries etc.) usually avaiable from farm chem suppliers etc. sachet (0.4gm GA x 2.5gm = 1gm GA )mix with 1 litre of water= stock soln. 1000ppm. take half of the 1000ppm soln. and dilute 1:1 with water and you then have another stock soln. of 500ppm. 500ml @ 1000ppm and 1 litre @ 500ppm with these two you can make up dilutions of any strength needed. store it in a dark place and will last a long time. John Mc, if you cant locate any just email me. | About the Author Speedy Nthn Vic 6th September 2012 10:54pm #UserID: 2305 Posts: 250 View All Speedy's Edible Fruit Trees |

John Mc says... Many thanks Speedy, I placed an order with Phoenix last night. They are short on details on quantity, but say one pack is enough to make up 20 litres, but at what strength? we'll have to wait and see. Going by your calculations, Speedy, they would have to be sending me 20grams to make up 20lits @ 1000ppm. I ordered two packets + postage =$17. I'm not counting on getting a great deal, as long as there is enough to germinate the Myrica Rubra seeds I'll be very happy. | About the Author JohnMc1 Warnervale NSW 7th September 2012 4:15pm #UserID: 2743 Posts: 2043 View All JohnMc1's Edible Fruit Trees |
Speedy says... yes, 20gms (of pure GA-3) with 20litres water to make 1000ppm solution. if it's 400gm/kg powder like the one I mentioned , it would be 50gms of powder. I reckon it may be the same concentration of powder, but "up to 20litres" will be at lower concentration solution. ie. 20 litres /2sachets + 10 litres per sachet would mean a 100ppm solution. you may not get much of a response at concentrations below that, so best to mix stock solutions at 500ppm and 1000ppm and dilute as needed. ie. 1part 500ppm with 4parts water to achieve 100ppm , but you obviously can't go the other way :-) this is all speculation though, so best to wit and see what concentration it is when you get it. let me know when it arrives. I'd be interested to know what concentration it it in the sachets. | About the Author Speedy Nthn Vic 13th September 2012 9:02am #UserID: 2305 Posts: 250 View All Speedy's Edible Fruit Trees |

BJ says... Any news on the GA3 John Mc? I've got a few rare annona as well as the Bayberry seeds that could all use a bit of GA3. The other supplier is Herbalistics, but theirs only goes 100mL http://herbalistics.com.au/shop/catalog/product_info.php?products_id=687 | About the Author Theposterformerlyknownas Brisbane 21st September 2012 12:05pm #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

John Mc says... The amount of GA-3 from Phoenix is as expected, disappointing. There's a few grains of crystal in the bottom of a small plastic bag. The weight would be the same as herbalistics. Luckily I bought two packets because I mixed my first packet up with 1 lit of water before contacting them. That makes the first dilution probably around 100ppm, -useless. The second packet I'll mix into 100ml of water, hopefully to get closer to 1000ppm. | About the Author JohnMc1 Warnervale NSW 21st September 2012 8:07pm #UserID: 2743 Posts: 2043 View All JohnMc1's Edible Fruit Trees |

BJ says... Mike, I found this while looking for info: http://www.tandfonline.com/doi/abs/10.1080/15228860903303999#preview Bayberries and ilama may also require GA3 for decent germination rates. Junglesop definately does not require any pre treatment. | About the Author Theposterformerlyknownas Brisbane 23rd October 2012 10:10am #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

Mike J says... I notice most of the people posting on this page have difficulty in getting GA3. I ended up so frustrated that I got onto the manufacturers in China and pestered them until one of them would sell me a kilogram. I only wanted 5 grams but Aussie dealers wanted $75 per gram at the time. The Chinese were reasonable and I landed it in my mail box for just a bit more than I would have paid for 5 gm in Oz. When using GA3, it is essential that it is dissolved in ethanol first and then mix it with water to the final dilution you want. Metho is OK as is Johnny Walker Red. Be damned if I would use any better whiskey than that though. | About the Author Mike J Mackay 10th July 2013 5:31pm #UserID: 8095 Posts: 6 View All Mike J's Edible Fruit Trees |

MIke T1 says... I got a bit for free but only maybe 10g.Its usefulness is limited to just the few recalcitrant and hard seeds that bedevil standard efforts.I had a little success with ilama and bayberry but don't go to 1000ppm as half this concentration of GA3 is better.Beware etoliation and never soak for more than 24 hrs and don't water with the stuff.Divide into the smallest accurate lot you can before mixing and you don't need ethanol.1g into 8 equal parts is easy enough and put in 125ml to 250ml of pure water.Wrap seeds in tissues and throw in.That is enough to do dozens of big seeds.Dont use the stuff for tomatoes and the like. | About the Author MIke T1 cairns 29th July 2015 3:37pm #UserID: 10744 Posts: 250 View All MIke T1's Edible Fruit Trees |
sternus1 says... Chances are if you have to use GA3, whatever you're trying to germinate is going to struggle. The inverse is also true. For bayberry, shelling them increases germination rates dramatically.I hear talk of striation but I've never found it necessary, they're just one of those things that take a long time to germinate. Also, they come from the Yangtze which is subtropical, not really temperate. Equivalent in Australia would be Northen NSW.There's absolutely no reason to use GA3 on things like solanums or other common garden variety stuff--it would probably be counterproductive and an expensive waste of time. | About the Author sternus1 Australia 29th July 2015 5:40pm #UserID: 8314 Posts: 1318 View All sternus1's Edible Fruit Trees |
