Cabbage worms
Small blue caterpillars are turning my cabbages into lace doilies.
What can I use to control them that is not harmful to humans eating the cabbage? |

The only place i could find it locally was Post Nursery off of 401 a bit north of burlington mills rd. The place for pot growers off of hillsboro street (5th season or something like that) might have it. Some Ace Hardwares might have it. Also either permethrins or pyrethrins (Whichever one is in Rotenone). I've seen Rotenone in Ace and Walmart. The other thing to try is bifenthrin (Ortho Max for granules, I forget the name for the liquid for spraying). Follow the california guidelines for use on food crops if you're paranoid about residue. It's a synthetic version of the previous item complete with a fairly high half life. -- Chris Dukes davej eskimos have hundreds of words for snow. I have two. Bullshit. |

They are pretty chewed up, but then the heads have barely begun to form. Seems like there's plenty of time for new, healthy growth. That is hard to tell. But since it is June it is a bit late for cabbage. With the heat they will probably bolt to seed anyway. Cabbage needs to be planted in February. Ours bolted in late April or early May. -- Wes Dukes (wdukes.pobox@com) Swap the . and the @ to email me please. is a garbage address. |

I'm gonna have to read up on this stuff before I try it again. At least my tomatoes are doing well. Can anyone point me to a schedule of recommended planting times for this area? |

Try this info from NCSU. Even shows a planting layout with dates. http://www.ces.ncsu.edu/depts/hort/hil/ag-06.html A lot of those March 1 dates I would move back to as early as Feb 15 in warmer years. -- Wes Dukes (wdukes.pobox@com) Swap the . and the @ to email me please. is a garbage address. |

Will the plants recover when the worms are gone? They are pretty chewed up, but then the heads have barely begun to form. Seems like there's plenty of time for new, healthy growth. Weeds and worms run the same schedule in early spring. Once they have a leg up on you you are in a catch up game. My motto has changed to work the hardest in early spring and the rewards will come through in the harvest. Our personal choice is to use liquid sevin for the worms. It's very effective to save you broccoli and cabbage. We attack early and often. For weeds we use the school of hard labor and a hoe. Again, early and often. Once the canopy of the crop is up the sun will not get to the weeds as effective. Good luck and keep up with your open desire to learn. Craig |
