Zucchini Yellow Mosaic Virus

Leaf and fruit symptoms.

	Severe warts or bumpiness are typical of fruits infected with ZYMV.
	Leaves appear as if they were exposed to a phenoxy type herbicide such as 2,4-D. While these leaf symptoms were assumed to be characteristic of ZYMV, lately, there has been some confusion in field diagnosis due to the similarity of leaf symptoms with other virus diseases, (see watermelon and squash mosaic leaf symptoms).
