CUCUMBERS


Belly Rot- Belly Rot is soil borne and caused by fungus Rhizoctonia solani. When the fruit touch infected soil symptoms can appear within 24 hours. Rotting the fruit in 72 hours.  The smaller fruit turn yellowish brown while the large fruit have dark brown water-soaked decay most often on the side of the fruit in contact with the soil. If the lesion is allowed to dry for a few hours the water soaked areas turn scabby and cracked. Using egg cartons to fit onto the fruit to create a barrier from the soil can prevent it. Also using a barrier like cardboard directly on the soil under the cucumbers can work.







Bacterial Spot- Caused by bacteria Pseudomonas syringae and lachrymans. Symptoms begin as small round lesions. The lesions start sinking and turn white. If found early on buds use less or no irrigation as water helps it thrive.








Cottony Leak- Caused by pathogen Pythium aphanidermatum. The most common symptom is fruit rotting. If it's more wet then normal during the season the vine can develop cankers. Rotation is suggested to prevent cottony leak.
