During our open forum seminar, discussion was brought to the floor regarding issues pertaining to proper tomato culture and care. In further research of the issue, I came across the following link pertaining to various problems with good and healthy tomato pants and fruiting.

The information herein should offer suggestions to a good and healthy tomato harvest with fewer problems in their culture.

In reference to insect holes in basal plants. My feeling is that various worms are the culprit doing damage during the night hours as they are nocturnal and are not visible during the daylight hours.
From further research, I found the following example of basal and insect damage brought on during the night hours. Note: This example is only a possibility as there are numerous insects that can devastate basal plants in the garden.
