Question
For the last 3 years when the Egg Plants are ready to pick
I find holes from the outside and discover worm like
pests inside.  What can I use to prevent this and when
do I act to prevent this.  Other people in this area are
having the same problem

Answer
Helen, the best organic control for worms and caterpillars is a product called BT, short for Bacillus Thuringiensis. This product is 100% organic and comes only in powder form. It is commonly sold under the names Dipel, Green Step, or MVP. If you cannot find it at your local garden center, you can purchase it online at either Planet Natural or Gardens Alive.

Another organic control that is effective against caterpillars and worms is diatomaceous earth. This product is comprised of crushed fossilized diatoms. Although it is broken down into a fine powder, the shavings are extremely abrasive to soft-bodied creatures, such as caterpillars, worms, and centipedes. When they crawl through the powder, their bodies absorb the substance through their exoskeleton, causing them to slowly die from dehydration. In short, the abrasive shavings result in very small cuts on the worm's body causing them to lose fluid and perish.

I hope this information helps. Good luck, and please write again if I can ever be of assistance.
