Your rating: None

Affected green fruit have large patches of hard, grayish or yellowish tissue. The affected fruit appears to be poorly ripened or to have ripened at an uneven rate with some patches remaining gray or turning yellow. Inside the fruit, there is uneven coloration of tissue with some areas having a brown color. Some blotchy ripening symptoms are similar to those caused by tomato mosaic virus (ToMV) on fruit. To distinguish the disorders, ToMV causes mottling and distortion of foliage, but graywall will not affect foliage.
