I think Bayer Advanced Systemic Rose & Flower may be what you are looking for. It also contains cyfluthrin.
Bayer Advanced Tree & Shrub Insect Control lists imidacloprid as the only active ingredient.
You will have to make your own decisions but I intend to try less toxic controls before resorting to this solution. I would be very interested to hear if anyone has had success with azadiractin (neem) to suppress feeding? |

| Hi Green hands...tnx for the info. I'm not afraid to use toxic products for certain creepy crawlies...:-) and those pesky lily beetles are one of them....but would try anything that works thats not off the wall. Franklin |

| Franklin, I fully agree that the lily beetle larvae are right up among the top of list for nasty garden pests but I'm an integrated pest management believer so I'm always looking of the least toxic solution. That said, for something like pine weevil which, to my knowledge, has no less toxic solution I'll happily turn to imidacloprid. |

Hi Green hands...I agree with your least toxic route for the most part...:-)...but I do wage war on certain critters with no holds barred...:-) I can't hack the organic position in all areas and at all times. Another of the real problems I have is japanese beetles...though this year they arn't nearly as bad as in the past...seems the winter past may have put a crimp in their numbers...or maybe they are late in comin' around. Deer...our antlered friends...ya gotta love um...but not in the garden and yard. Installed a seven foot high plastic deer fence around most of my vital stuff...cos I couldn't find an organic method that would keep them from munch-a-rooin' where they wanted...:-)...have found over the years that organic methods to retraint deer are just so much b---s---...when they want to eat your stuff they will eat it.
Have lived here in southern Maine for five years. Lived coastal New Hampshire...and south central NH before that. Franklin

| Neem is a soap, made from a tree in India. It's a poison, just one that happens to occur in nature. There is a list on the label of what plants you can't use it on. Not sure if lilies are among them. Basically it just gums things up and also makes the landing pad slippery. Unfortunately it works to keep off beneficial insects too. |

As far as pesticides go, imidacloprid is relatively innocuous. It's the same stuff in Bayer Advantix that people put on their dogs to control fleas and ticks. I've used it before (on my dogs) and I figure if I'll put it on my dogs, I sure as heck don't mind putting it on my lilies and roses. It's done a fabulous job on the lily beetles, and I'm going to use it on the roses for Japanese beetles this year.
Don't forget, organic doesn't necessarily mean non-toxic. Some chemical pesticides are less toxic than organic ones. |
Data sheets
| | |
| I have no idea whether or not it is effective but Aza (neem)is listed as low toxicity (class IV, the lowest category) pesticide which poses little threat to pollinators and beneficial insects. Both imidcloprid (class II or III) and cyfluthrin (class II or I)are listed as moderately toxic and definitely toxic to pollinators. As I noted I'm not trying to make decisions for other people but we all have an obligation to be fully informed about the choices we make. |

| When the lily leaf beetle first arrived, we tried hand-picking. They kept appearing in various stages of development--beetles, eggs, and those disgusting grubs. 2nd plan of attack was Neem, which had no affect at all. After two years of fighting them organically, my 3rd plan of attack was to rip up every single one of my lilies, which I did. Went lily-less for two years. Then I heard about Bayer Rose & Flower with Imidacloprid. I tried it on my client's lilies, because she refused to give them up. It worked very well, spraying once as soon as the first beetles were spotted in the spring, two weeks later, and then sporadically throughout the summer whenever beetles were discovered. I consider myself an organic gardener, do not use any other pesticides, build my soil very well, etc. But IMO, Imidacloprid is the only way one can grow lilies around here. I bought a few new lily bulbs last fall and have kept them fairly clean with the Bayer. |

Green Hands, you are right about the toxicity to pollinators. That's why the Bayer Advantage should only be sprayed in the very early morning or at night when pollinators are not active. Once it dries, it is no longer toxic to pollinators. Imidacloprid is a systemic pesticide, and is toxic to any insect that eats the leaves.
I would urge anyone thinking about spraying anything to contact the Cooperative Extension first. I have attached a link, and Colin Stewart, the Homeowner IPM specialist, (contact info on the web page) is a very friendly, knowledgeable person. |
