Phase,

I have been using this product for appx. a year now. For me Exel(along with an excellent slow release fert.) has played a major part in my trees growth?health. There are some people that don't like using it because it is a systemic. The only reason I even started using it was because it was recommended by lycheesonline. I figured it was good enough for their orchard its good enough for me. You might want to check with the company as CA has very strict rules and regulations on fungicides and I'm not sure if this is approved in your state? I will stop using the product a few months before fruit set...

I am not recommending this to anyone just telling you that it has worked for me and have been very happy with my results...

If you want to email the company that makes it here is their website:

I ordered mine from the link below (Florida)

Here is a link that might be useful: Exel LG phto- fos Fungicide

puglvr1, thanks for the link and sharing your experience. I just placed an order from lawnrite: Exel LG phyto-fos, MycoStim root, and Green Lightnin Mist & Feed. The former two are both recommended by Lycheesonline.

why do you mix phyto-fos for your lychee trees? do you also spray it on the new flushes? I don't know if it will damage the tender new leaves.

why would you stop using it months before the fruit set? Isn't that when the tree needs P the most? according to lycheesonline:

"Late September through early October is the time to begin girdling your trees. At the same time you girdle your lychee tree you should use a higher phosphate content fertilizer which is known to boost bloom"

typo: how do you mix phyto-fos for your lychee trees?

The owner of Hopkins nursery spoke positively about Phosphorous Acid (not phosphoric acid), and I bought that Excel. Tried to save my problematic mango trees with it, it didn't work, but there could have been other things causing the problems. It sounds like a worthwhile product to use. If you surf hard for info on it, there is some good things out there to read about it. I bought mine on the web for a pretty good price. I think I've since seen it at a local store.

Phase, I use per recommendations on lycheesonline 1-2 Table per gallon of water. I do spray mine once a month, but especially during a leaf flush.I do it early in the morning before 7 AM. It gives it time to dry a little before our hot fl sun hits it. I use it on my Mango also, but only 3/4 teaspoon per gallon. It a little less on the directions for Mango trees.

I am suppose to use it during flowerin/fruiting, and I probably will do that, its just because of the systemic part and I thought it might be a little questionable because of the fungicide. But again if they use it safely on their orchard, I guess I will just keep using it.

You're welcome, glad you were able to order it.

The girdling, I am not quite ready to do yet on my tree. They are still young, and I don't wan't or feel comfortable with the technique to mess with it yet, maybe a couple of years if I don't get fruit by then...

puglvr1, thanks for the tips. I am glad that the new leaves are fine with the spray. My order should arrive on Saturday or Monday. Can't wait since my lychee has a new leaf flush going on now.

Phase, for the mango trees,meant to say 3/4 teaspoon for 44 ounces or 1 Table for gallon of water. This stuff last a long time for me, I have been using it on 8-9 fruit trees appx. once a month for a year, and I still have some left.

It is definitely recommended to use especially during a leaf flush. I have never seen any bad effects on the new growth, just make sure to apply in very early morning. Before the hot gets hot...

Good luck and hope it works well for you.
