Any hormone product i.e. ethylene available for use on a few pineapple plants?
Mark in Texas:
Had a big crop of pineapples last year. This year only one small one with some clones like Cayenne being at least 3 years old and quite large and never fruiting. Twistees fruit quite well and on their own. Would rather use a spray than an apple piece to induce fruit.
Thanks

Calcium carbide + water produces acetylene gas which forces pineapples.
I asked the same question in another pineapple thread and purchased a bottle online. Forced mine last week but it takes a few weeks for the flower to develop.
I tried apple cores for ethylene but it didn't work for me. Rodents stole the apple even after the pineapple leaves were tied together. They chewed through the leaves.

I use calcium carbide that I bought on eBay. I add a few pieces in some water and pour it into the pineapple at night. Works nearly 100% of the time.
Finca La Isla:
We can by 'Ethrel' which is for flower induction on pineapples or for help in ripening different fruits. Barring that I have used carbide. In a 1liter bottle with water I put perhaps 50grams and let it bubble away. The gas that comes off that event is flammable. The remaining solution can be diluted about 10-1. Pour a couple to three tablespoons into the leaf axils of each pine that is fully developed.

Thanks for the info. That "free" pineapple can now run big bucks when you figure in a PGR. Found a pound of carbide for $17 plus postage.
