Hello, I have a mango tree which is 3 years old and planted inside a greenhouse in Lebanon in the Middle East Region. According to a plant pathologist the tree is infected by Anthracnose disease. I sprayed it with Copper and Mancozeb fungicide 3 times every 3 weeks. Now the fruit is small and it is cracked as shown in the pictures attached. What is the problem that causes this cracks in the fruits? And how can I solve this problem? Thank you for your help and consideration. Best Regards, Karim.
