Colorado Potato beetle - Leptinotarsa decemlineata

http://ColoradoP.notlong.com

1 June 2006. The Colorado Potato Beetle made its appearance today. I picked bout 15 off the potato plants, and removed some eggs on the underside of some leaves. Potatoes have been grown the last three years, and every year there are a few more Colorado Potato Beetles. All I do is pick them off the plants daily, since they are not in quantity.

Years ago my small potato patch was destroyed in one long weekend. Upon returning from a trip the potato leaves were completely covered or what was left of them. With a large infestation and a large field spraying is necessary. Good luck for the organic gardeners.

Hi Durgan,

Last year and for the first time, I had a problem with cucumber beetles. Since I grow organically, I searched high and low for something to get rid of them, while keeping things organic. I discovered that neem oil is highly effective in ridding my cucumber plants of beetles and I notice that it is also recommended for the Colorado potato beetle. You might want to give it a try.

So far I can control the potato beetle by picking, but I will get some Neem Oil as insurance. In the old days we used Paris Green, which was used universally, and the base is arsenic. So much for the good old days. I had cucumber beetles last year, but not enough to be overly concerned.

Well, I guess the pretty Colorado beetle is not a welcome guest. Earlier, here in Denmark, you had to report to the Plant Directorate if you found the Colorado Beetle, but nowadays this is not required.

An interesting notice I came across is that tests show that attack from colorado beetle should be less severe, when you are using compost and manure compared to fertilizer.

Toads and certain birds like for example pheasant like to eat them, so maybe they could help controlling them.

Fortunately I have never seen it in our garden, although it was observed several times last year - also a few kilometers from here.

The Colorado Potato Beetle is a fact of life in North America. I have lived all over Canada and always encountered the beetle. Commercial potato growers practically cover the crop in spray. As a child we used Paris Green, then DDT. Only a few know what is used now, but it will be probably as harmful to the environment.

Anybody who thinks commercial crops can be grown on a large scale without spraying, when necessary, is dreaming in technicolor. Organic Gardening is possible on a small scale only. My half witted neighbors spray their lawns to eliminate dandelions, and any broad leafed plant in the vicinity. My broccoli plants now have twisted leaves from the wind blown spray. You figure.
