What is the difference between Chlorosis, Coulure and Millanderage?

Answer 4

Chlorosis is caused by a lack of nutrients. The leaves yellow, and photosynthesis is restricted. Grapes struggle to ripen, and quality and quantity are reduced. Remedied with the necessary fertilizer.

Coulure is caused by cold, cloudy, and rainy weather during pollination and results in a lower than usual volume of flowers being pollinated.
