Please guide me about this problem in grapefruit and suggest solutions?

I agree with Sali

Hi Waqar Ali as per your images the symtoms are quite similar to Citrus Greening Disease Please click the above link to know all information about this disease. How many plants have such symtoms in your plot?

Shahzaib Kashan Bhutta Citrus Greening Disease looks similiar to my problem but how to apply the suggested solution? The affested fruit in my orchard, if i say in percentage, is less than 5 percent. And dont you think its early stages of citrus canker. What you say about this?

Thank you Waqar Ali 😊 For Canker disease in grapefruit, pls ck in Plantix library for Citrus Canker and compare. I think it’s not similar to your fruit's damage.

Waqar Ali Pls ck if there's psyllids are available in your orchard, the nymph are also involved in transmitting this bacteria for spreading to new leaves and fruits. So, spray insecticide like Imidacloprid or Dimethoate for effective control of both nymph and adults psyllids. Citrus Psyllid, click here to know about psyllids.

Hi Waqar Ali can you please share few images of effected Leaves?

Hi Waqar Ali Can you please Share how many plants are affected? This spread via sucking Insect pests like Citrus Psyllid

Shahzaib Kashan Bhutta Leaves are not afected, yellow spots appeared on fruits only. I will check psyllid in orchard and if found will go for treatment. Will this be enough or i should do something else also?

Waqar Ali yes
