He quoted a UC plant pathologist, who years ago dubbed almond hull rot the “gout of almonds.” He also discussed studies that show a connection between nitrogen and hull rot, saying they show the more nitrogen the crop received, the more often hull rot became a problem.

He said growers should use the nitrogen they need for the crop, but be aware of what it could mean for hull rot.

There’s more information on nitrogen and hull rot on the UC IPM website.
