pomegranate disease question

Hi,

I tried searching for this problem on helpful gardener - no results :)

My Pomogranates seem to be having spots on them.. What could be the cause of this ?

It looks like anthrachnose. Check to see if there are spots on the leaves too. It would be a problem in humid weather. Good sanitation helps control the disease as well as opening up the canopy to improve air circulation. If the problem is severe or other fruit trees are also infected, you may need to have an anti fungal preventive spray program when the humid weather hits.

Thanks ! Yes it must be this. But not as bad as the pic in agropedia. Will spray neem tomorrow and diluted cow urine day after. We are running foggy weather now.

Thanks

Neem may not work at this point. Most fungal problems are better prevented than treated. I would remove all the infected fruit and leaves and bag and destroy. Do not compost. You can try a copper sulfate or Bordeaux spray which will last a little longer to try to limit the spread. Fungicides are best applied on the new growth early on and preventively when humid conditions prevail. Below is a link to making your own Bordeaux mix. Bonide sells the powdered copper sulfate as a dust. The orchard tree fungicide also contains sulfur. Read the entire label and take all the precautions indicated. Copper stains. If you can get sulfur dust without the copper, it does not stain. Good luck, I have had problems finding sulfur dust for awhile now.
