Title: Is this asian citrus psyllid? What to do?
Post by: Malia on June 20, 2019, 01:12:30 PM
I have just bought 4 citrus bushes + 1 Eureka lemon.

I found 4 of them on Eureka lemon today. Some more on other bushes.
Is there any hope for the plants? What would you do?
I am a novice and will follow your advice.

Thanks!

Looks too big. The acp is very tiny. Look the size of an ant or smaller. To keep pesr off your citrus chronically use Spinosid. Or hand pick them off. You can use Bayer systenic drench too.

looks  like an ACP to me.

What other bushes did you find them on? If you think this is acp, call your county agent. I am sure he will be interested and determine what you have.

Your pic is not clear enough for me to positivly identify this. Can you post a clearer close up?

Agree with Millet. Looks like ACP on new growth.

Where did you buy them?

I see that you are in Florida.....you need to let the right people check out your citrus
 Depends on where in Florida you got them as to next move

I bought them:
thorny key lime at Excalibur almost 2 weeks ago
Eureka lemon and Orange 2 days ago at Lowes in Lake Park
Cocktail key lime + Meyer lemon together in one container and Persian lime at Home Depot in Jupiter a week ago.

They are all still in containers. I planned to plant them in the bottomless planters around the house, but now I will plant them in planters with bottoms. They will die anyway.

Thanks. "right people" you mean that "local extension" which is referred to everywhere?

Thank you for all the help.

Referring to your posts:
1. Yes, it is on new growth. On Key lime actually, I mixed the containers up.
2. It is a very tiny insect. The picture is 8x zoom
3. All the bushes I referred to are citrus. I bought these miniature citrus bushes to plant in planters around the house. 5 containers altogether.
4. I am afraid it is the best picture I have taken. I will try tomorrow again. Or rather I hope all bugs will be done after neem oil spray.

Bomand, excuse me this question, what is county agent?

Spraying with neem oil didn't help. What do you spray on ACP?

Bomand, what do they do at cooperative extension? Will they confiscate my plants??

Title: Re: Is this asian citrus psyllid? What to do?
Post by: Bomand on June 21, 2019, 01:05:29 PM
If they have acp they will probably destroy the plants. A good thing for citrus. I know its a loss for you but the plants can be replaced. When and if you do there are plants certified hlb free. Keep your new plants sprayed. Use Spinosid and Malithion
 They will kill acp and other pest
You can use neem oil but not in hot weather. Temp has to be under 80 degrees or Neem will kill citrus. Understand that Florida has a terrible greening problem and you will have to deal with it. If you are a novice citrus person there are hundreds of pages to read about it. This forum has a multitude of people full of good information
 Start with clean plants, keep them healthy, well nourished and free of pest. Use certified Budwood from ccpp and hope the cure/help for greening happens sooner rather than later. Help/cure is coming....I cant say when.

Bamand, thanks for all the advice! I appreciate. Being a citrus novice (well, a novice to gardening too), I think I will give up citrus completely for now. I will wait for the cure.
Title: Re: Is this asian citrus psyllid? What to do?
Post by: Millet on June 21, 2019, 09:02:08 PM
Malia, the cure to citrus Greening could be a long way off.   The authorities will not confiscate your tree just for having psyllids feeding on them.  However, they will confiscate your trees if they are proven to already be infected with HLB.  In your case, if these particular psyllids on your tree have indeed infected your tree with HLB, it will be approximately 3 years before any symptoms appear.

Malia, you can return your trees you bought from Lowe's and HD.

According to research by Laura Waldo a UF scientist,  tests of tricalcium phosphate (TCP) has potential use as a fertilizer that might help citrus growers cope with HLB. The research is that it helps a tree by inducing root hair development and thereby allowing the tree to uptake nutrients more efficiently

i use this about once a week just to control mosquito's & gnat's but it helps with other insects as well...

I find some of them on my tangerine tree.  What is that and how I can get rid of them?

Looks too big to be an Asian psyllid.  Flip it over for a better shot.  Might be a leaf hopper or some small moth.

This is the best shot I can took.

I got this picture from search.  The pest from my tree look like this picture but different color.



What is a good organic product I can spray to keep the tree from pest?

Thanks....

Spinosid.

Post by: Yorgos on July 03, 2019, 02:43:01 PM
Its a leaf hopper. Not sure what a sponosid is.  They are an insect with piercing mouth parts for sucking plant juices.

Thank you Yorgos.  Do you know any organic pesticide I can use to get rid of them?

I found this in Amazon.  Had anyone tried it before?

If a citrus tree is in a Citrus Greening area such as Florida with active ACP, the chance of the tree getting citrus greening is about 100 percent.  You can spray all you wish but it is still about 100 percent.  All it takes is just one infected psyllid bite.  HLB presently has not cure.  The only treatment to insure that a citrus tree will not be infected would to build a screen around the tree to keep the psyllids from ever landing and feeding on the tree.

Post by: Millet on July 03, 2019, 06:58:51 PM
For season long control of the ACP psyllid:
For season-long protection, use MoventoŽ at pre-bloom to help control ACP and red scale. At full-bloom, use SivantoŽ Prime to help control ACP and citricola scale and to suppress citrus thrips. Using AdmireŽ Pro at post-bloom promotes further protection against ACP and citricola scale. At fruit growth, Movento helps control ACP, and during harvest, BaythroidŽ XL helps protect against ACP, citrus thrips and katydids.

Hi Millet,

In other word, unless put the tree inside the greenhouse otherwise there is no way to prevent the green disease from infected on the tree.  If it is infected, just destroyed it.

The more knowledge gain, the more worries about the citrus tree

pinkturtle, Florida is a dangerous place to grow citrus.
