This will be the first time when I will use GA3 for pollination, thanks to you guys.

I need some advice from you before to do something wrong.

1. There is a problem if spraying in full blossom some leaves around will be also sprayed?
2. What ppm is the best to use? I’m asking because searching in the forum Millet is using 10ppm but JoeReal mentions 25ppm.

Thanks for help!

I have used 10 PPM for 15 years. It works great. The amount of spray falling on the leaves is not a problem. NOTE: Because GA3 works so well setting fruit, the tree will retain more fruit than normal. Due to the greater number of fruit set when GA3 is used, the fruit will be smaller than would normally be expected for the cultivar. Therefore, if you desire larger size fruit you will need to thin the crop a little. I've never used rates as high as 25-PPM, but I don't think, but not 100% sure, it would cause any problems. - Millet (627-)

Thank you very much Millet!
I will follow your advice.
Your help is much appreciated!
