Mango Pests, Diseases, and Nutritional Problems
« on: April 14, 2012, 10:27:07 AM »
The goal of this post is for everyone who has a mango pest, disease, or nutritional problem to post the picture here and for it to be diagnosed and be a future reference for others. Please only include your own pics and not pics pulled from the web.

I'll start, I noticed what appears to be eggs on my coconut cream mango tree. Can anyone tell what type of eggs so I know whether to get rid of them?

I'm not sure what type of eggs they are, but I would get a napkin and wipe them off.

I say a heavy dose of malathion, or Sevin mixed with some neem oil or horticultural oil to make sure it suffocates and kill those intruders. While you are at it give that poor tree some copper to get rid of all that anthracnose. I'm done playing Mr. nice guy with pests on my fruit trees.

I think that's over kill. I rather not spray my trees with too many strong pesticides. Since I don't know what type of eggs they are I don't plan on getting rid of them. I try not to spray copper that often either.

Enduser's advice sounds good to me.  Perhaps start off with a pesticide, if that doesn't kill the critters, try something stronger.  The copper makes sense since your tree has anthracnose.

Why would I want to kill something I haven't yet identified? Even after identifying it, why would be first choice be to use a pesticide? Why not let the other bugs handle it. Mango trees are pretty good at taking care of themselves. I don't think I have ever had to spray a pesticide on any mango tree I've planted in the ground.

The reason the copper doesn't make sense to me is that over use of copper can be damaging to the environment and unless my tree is flowering and I am possibly going to lose a large amount of fruit I see no need to spray copper on my tree.

I agree with you on no heavy dose of pesticide for your tree.  Like you said, better to first find out what they are as it doesn't seem to be causing any damage at the moment.

As for copper, if you are having major anthracnose issues or some other invasive fungal issues I would attack with a strong regime of copper.  Otherwise, once a month or even once every other month should more than suffice.  if you had fruit to "protect", that would be different.

I agree that it's not wise to spray even before you know what you are spraying for. If you can't ID the eggs just keep close eye on them till start hatching. As for anthracnose i think that the tree can be weakened if it has anthracnose, so it would be good to spray copper on it. You can greatly minimize any soil damage caused by copper foliar spray by just using a tarp under the tree that catches anything that drips to the ground.

Oscar and Rob, I agree about copper for Anthracnose but luckily this tree is not really showing any visible signs. The tree as a whole looks really good so I see no need to spray it. I may hit it with one or two copper sprays during the summer(with a tarp underneath to collect any copper runoff of course).

I think those may be weevil eggs.  See these links.

I don't know why you want to wait and see what hatches before treating it.  From the picture, it looks like several of the eggs hatched.


Palm weevil eggs on mangos? I didn't think mangos are a host plant for palm weevil?

Agreed, plus, that Science Advisory Board does not even list the U.S. as a country affected.

In everyone's experience, what are the negative effects of spraying copper?

Florida has an infestation of Sri Lanka Weevils; I can't find pictures of their eggs on the internet. http://lee.ifas.ufl.edu/Hort/UsefulLawnandGardenResources/SriLankaWeevilupdate2008.pdf

However, I was able to find pictures of another weevil's eggs.  The picture of the eggs look similar to weevil.  The description of the eggs is:  "Eggs:  The eggs are creamy white in color, long and oval in shape. The average size of an egg is 2.6 mm long and 1.1 mm wide." 

Hope noone from Florida mailed anything to Hawaii...the penalties are severe:  http://hawaii.gov/hdoa/pi/pq/penalty

If you googled Sri Lanka Weevil egg, the first result would show you a picture of the egg: http://trec.ifas.ufl.edu/mannion/pdfs/SriLankaWeevil.pdf

It also explains that the egg is laid in the soil.

I think Mr. Clean is right. I saw some weevil couples on top of each other... So it's the special time of year.  ;D They were on my ndm #4 so I crushed those horny mofos... lol    Trying to spread your population and eat up my trees? I don't think so....  :P

I am not sure what eggs those are from, but agree to let nature take its course first.  A balanced garden is a healthy garden.

Regarding the Anthracnose; my mango's had (note past tense  ;D) severe anthracnose because they were uncared for as this property sat empty for four years before I purchased it.  I used a new earthfriendly product from Organic Labs http://www.organiclabs.com/Retail.html called Plant Doctor and the Anthracnose cleared up completely!
You can get it at Home Depot .. I also got their Fruit Maker as a folier spray of Potassium.  It was developed at Texas A&M as a form of Potassium that uptakes significantly more than granular.

Good idea. I will check it later.

Honestly, I don't really care what they are as you can probably tell from my anti spraying attitude. I would probably leave them along regardless. I just posted so others would post stuff to get the thread going so it could be a good reference.

One thing to keep in mind here -- copper will not clear up (ie, remove) existing anthracnose damage on leaves / fruit. It will simply prevent anthracnose infection on uninfected leaves / fruit.

I noticed some Anthracnose on my mangoes and sprayed them with copper.  How long does it take for the Anthracnose to clear up?

The website states that you can get it at HD, but HD only carries a different product then the one shown on the vendor website. The HD version is a combo product that is not shown in the vendor website.

Do you have a HD sku number for the Organocide™ Plant Doctor?


The sku is on this http://www.organiclabs.com/Images/LabelImages/Plant%20Doctor%20Back%20Label%20Booklet%20Instructions%20for%20Use.pdf
It is at the Home Depot in Jupiter and you can also find it online at Ebay. 
It clears up Anthracnose faster and better than anything I have ever used.
