Limes with brown streaks in fruit

Question

My limes develop brown streaks from flower to stem just as they get ripe. Why? I have problems with ants, scale and mold in limited locations, but the brown streaks are universal. I pulled 50 from the tree this week and 90% were effected. I am going to spray with a canola oil, but I have to wait for the hummingbirds to move on.

Answer 1

Discolored streaks on citrus is referred to as tearstaining and is commonly caused by anthracnose. For more information, visit the following article:
