I have holes in my basil plants and I want to treat them with something that is safe for human consumption
Neem Oil is a good organic treatment.

hi all of a sudden my basil (sweet basil) plants suddenly wilt and shrivel. starting from the top. no bugs anywhere, at least not on leaves. soil is fresh from large bags. problem is only in one container. i grow the basil on the roof in NYC and gets good sun, water. had just put in agri-fos, a safe fungicide and never any trouble before. other pots have same mulch, soil, water, agr-fos, etc but are healthy. normally fungus would take a while to affect plants. stem turns brown and plant slowly dies. this is first time the plant quickly wilted without any signs. wilting starts at upper leaves and droop over. stem curves down. bottom leaves healthy but soon wilt. only one section of one pot has trouble so far. all other plants are fine. i gave all the plants another agri-fos spray. i also sprayed when there was no problems which should have prevented any fungus. so this is a mystery. when i pulled a wilting plant up the main root was nice and long. didnt see any bugs. thanks louis Lou707@msn.com
This is likely caused by Fusarium Wilt.

I do not know if this is normal or not but I am growing this Genovese basil plant for about 2 months now and all of a sudden one of the base leafs falls off. On the second base leaf which hasn't fallen yet had this strange grey spot as showed in the pictures. I would just like some advice on how I can help my basil and what the heck is happing to the base leaves.
These first two leaves are called cotyledons and it is perfectly normal for them to fall off. This article will help

Why are the leaves of my basil plant starting to turn silvery-gray, in a speckled pattern? They get a morning light and I couldn't tell you what was in the potting soil. It was all I had here in Austria. THanks, Lora
This sounds like a pest infestation on your Basil.
Treat with Neem Oil.

Re-posting this to see if I can get my picture to accompany it this time (it didn't work last time--is 2.2MB JPG): Why are the leaves of my basil plant starting to turn silvery-gray, in a speckled pattern?

This is from pests, Aphids.
I would pinch the plants and remove the most damaged leaves. Treat with Neem Oil.

Hello, You can use a product know at Bt. on your edibles. It is a bacteria specific to stopping caterpillars from being able to digest, then they just die.It stops the caterpillars but doesn't harm you food. Just have to wash thoroughly before eating. You should be able to get it at a proper plant nursery. I think Monteray Chemical make a version of this product that it ready to use. Check the label for your specific crop before using.If you want to go with beneficial insects Ladybugs and Lacewings should eat the eggs before they hatch and they can be ordered online or purchased at some nurseries. Release at night so they stay in your yard..
