problems in bay leaves

General    Morocco

Good morning, we are having a problem in some of our bay leaves plants. As you can see on the photos, they are appearing some irregular dark spots on the leaves, and then it seems that this patchs like burnt fall down. I do not know if it is related, but some plants are drying out by patchs.

Thank you.

Are you collecting images for automatic disease diagnosis using machine learning?

It looks like the plants are suffering from several problems. The tip burning (image 3) usually occurs due to salt injury. The black and brown spots may be due to bacteria or fungus. The best way is to look for spores under microscope or isolate the pathogen. The common diseases of bay leaves are shot hole disease, Phytophthora ramorum leaf spot.

Hello Mr. Ravishankar, what do you mean by collecting images for automatic disease diagnosis using machine learning? . All the images I am downloading are taken by us, by our technicians in the field. We have many different crops, more than 20, as we produce every kind of aromatic fresh herbs, some oriental products, hot peppers...

Thank you for your response.
