More Chard issues

Posted by robinlmorris SF Bay Area (My Page) on

Apparently insects love swiss chard as much as I do...
Earlier this year my chard plants got defeated by leaf miners.
Since then, I have been keeping the leaf miners at bay by removing any eggs I find and spraying with spinosad.
My chard recovered and I have been happily eating it for the last month or two.
Now I have a new slimy pest eating my shard. I have searched the internet but I am still clueless about what it is. Whatever it is, it is not bothered by the spinosad.
Any help is much appreciated!

Thanks,
Robin

Those look like aphids, commonly known as blackfly. They are sap suckers so are not responsible for the holes. A mild infestation is not much of a problem. Blast with the hose while growing. Wash them off before eating.

Thanks!
I wonder what is causing the holes then...
So many things love my chard!

Snails put holes in mine, and I have a feeling grasshoppers as well but haven't caught one in the act yet

RE: More Chard issues

I find snails will eat anything before they'll eat chard. However they do like to hide in big old plants. I've also never found aphids on chard. In fact it's pretty much pest free. Which is odd considering the problems US gardeners seem to have with it. Any thoughts as to why that might be?

RE: More Chard issues

Hello,

Not sure if my question is appropriate to this thread, but I've been growing swiss chard very successfully for many years until last year when I found lots of insect damage. Never saw the critter that caused the damage, and for full disclosure, I've been growing the swiss chard and beets in the same general area for several years now.

First indication of a problem was last year when I found some large (1/8th inch plus) holes in the leaves and some "perforation" (much smaller holes - under 1/16th of an inch).

This year I started my chard in the same area as last year (bad idea, i know) and transplanted a few dozen plants. Many of the transplants have done very well, but the last batch that I transplanted have "perforations" and today I think I saw the pest that caused the problem - a small (less that 1/8th of an inch) long insect, very black in color - looks sorta like an ant.

I don't want to use inorganic pesticides (for obvious reasons) and I think I'll try to capture a few of the bugs for identification. Just thought I would pass this by the forum in case someone can offer advise.

I'd like to eliminate the pest without using pesticides.

i started 1 swiss chard plant in a 1 gallon pot around july and kept it in part shade, to nibble on to tide me over until the cooler weather comes--when i can really get a good size chard crop going. That one did, and continues to do really well. Now I have started a couple rounds of autumn crop seedlings, and now have been having the same issues here. Munched holes in the leaves, along with the kale seedlings that are sitting beside it--yet no evidence left behind, no critters, not even any caterpillar poo. just those ugly munch holes.
