beating squash bugs in a market garden
I would post this in other forums but I am trying to control squash bugs on a larger scale. I have been staying organic so that, when my sales get to $5000/yr I will be able to get certified. Right now I am not so sure if I will be able to do it. I have MILLIONS of squash bugs and SB nymphs in the garden. They killed off 80 cucumber plants, 40 winter squash, almost all my melons (luckily I was able to harvest about half before they died), have killed off almost all of my plantings of summer squash and zucchini and they have started working on my watermelon. So far they haven't found the gourds and pumpkin but I am sure it is just a matter of time.
If I want to stay organic WHAT SHOULD I DO?? Liq. Rotenone/Pyrethrin doesn't kill them, DE doesn't seem to affect them, Pyola doesnt kill them, they laugh at neem, the onion/garlic/cayenne spray I used early in the season just added seasoning to their unending appetites! The only way I have found to kill them is to sqish them but I simply am not able to get all of them.
They were non-existant last year. I have no idea how they got so heavy so quickly! I have resolved that I can't save most of my garden this year but would really be unhappy if they kill off all of my fall decoratives--some of these pumpkins are quite unique.. I am also paranoid about what this will mean for next year. I understand that I should clean up all of the debris that they could overwinter in. Should I also remove all of the straw that I use for mulching my paths? I have a permanent raised bed system and feel like I shouldn't even try a winter cover crop because that would give them another place to hide.
What is your opinion??
