Systemic pest killers
I don't know about Home Depot but you could check Wallgreens or Ace or
others like grocers, hardware, ect. Bob "Minelli Family" wrote in message ... "Bob Walsh" wrote in message ... I recently had an infestation of mites. I talked to Jerry Fischer at Orchids Ltd. and he said to use insecticidal soap three times three days apart on all plants in the growing area. The problem seems greatly diminished, if not gone. I will spray all the plants before bringing them in next fall. Others have said just spraying mites with water is effective. I like the soap. I want them dead. Regarding the inside insects, put 3 quarts of water in a gallon container, add one pint of alcohol and one pint of orange 409. Spray weekly. I don't order online anymore after several disappointing experiences. Would Home Depot carry Orange 409 and the soaps? I know they carry the usual insecticides. I was at an Orchid class recently and one of the speaker/vendors announced that he had some plants with that he would no longer sell. He offered to show all who wanted to see why. The plants were in clear plastic pots. He had dropped one and when he picked it up and checked it for breakage he noticed mealy bug larva on many of the roots. Sprays won't kill those. unpotting, dipping and repotting will, but I wonder about the eggs.... Are they laid topside or down around the roots as well? I had cactus infested with root mealys about 10 years ago. I soaked them, in their pots, in Malathion and covered them with a plastic sheet for 24 hours to hold the fumes in. I did this a week apart for several weeks. It got them all. But now they may be resistant to Malathion. I believe the eggs are laid in the soil around the roots. |

Hot water at 120° F does not significantly affect potted Rhapispalms. For more information or a detailed report contact Arnold Hara in Hilo at Ph: (808) 974-4105, Fax: (808) 974-4110 or e-mail: . I remember reading somewhere else about using hot water on plants, I just don't remember where. Has anyone else seen that? I wonder if orchids would tolerate 120F? Or 115F? I have used 100F to wash newly acquired orchids _if_ pests were found. Both were Phals with mealies. I used alchohol to kill the visible bugs, then washed the plants, bare root, in 100F soapy water. Seems to have worked, but with the alchohol, and soap, and hot water ... well, I'm not sure just what did them in. This was about 18 months ago and I haven't seen any new mealies. I wonder about cactus too ... could they survive hot water? I really hate using harder drugs (I am easily hooked G) and just like using soap or alchohol. Bob Campoli - Philadelphia, Pa |

Our local Home depot's, Ace Hardware stores, feed and seed (like Tractor
supply, TSC) and all the organic garden stores carry inseciticidal soaps, usually the brand called Safer. "Bob Walsh" wrote in message . ..

FWIW, I find that so-called "insecticidal soaps" offer no advantage over
ordinary household liquid dishwashing detergents, and the same might be said for horticultural oils compared to vegetable cooking oils. My preferred spray for spot treatments is a tablespoon each of cooking oil and liquid dishwashing soap (I use a brand made from 100% vegetable and fruit oils) in a quart of water. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies.

Books, Artwork, and lots of Free Info! Ray, I've also used baby oil on a no ID Slc. applying it with a Q-Tip to kill some kind of orange mite. I applied it to every leaf surface (there are only 6) and down into the bract clasping the pseudobulb. That also seems to have worked. I did wash the leaves with soapy water a day or so later, because I was worried the oil wouldn't evaporate and would suffocate my plant. Bob campoli |

At that concentration, it doesn't. And it really does work. Diana |

Systemic pest killers
Hi all, Spring show season is about half over and I have to say that this year I have received more questions about mealies than any other year. Way more, it is as if the east coast is in the mist of a mealie infestation. I am not sure where they are all coming from, but at one show the vendor next to me was including mealies with his plants. Check plants before buying! It has been sort of weird, a lot of the people with mealies are convinced that the way to rid the problem is with alcohol even after multiple failed efforts. I am not sure where all the alcohol hype is coming from, but I bet it is not coming from a grower with more than 5 plants. With all the mealie questions I though maybe chemicals had been removed from the market, so I checked a garden center. Many of the old cures were still on the shelves (Orthene, Malathion and Sevin) as well as the newer weapon Imicloprid. The tools are still there, I just don't get it. Pat |

Wholesalers who don't usually have them (west coast...). I blame the west coast. *grin*. That might be the root of the problem. In the house I use alcohol to kill mealies with great success. But in the greenhouse I knock them down with alcohol and whack them with a systemic while they are staggering around drunk. That seems to take care of the mealies. -- Rob's Rules: http://littlefrogfarm.com 1) There is always room for one more orchid 2) There is always room for two more orchids 2a) See rule 1 3) When one has insufficient credit to obtain more orchids, obtain more credit |
