Insecticides

From: David Thornton dave at dave-aroid.demon.co.uk> on 2001.05.29 at 02:21:07(6593) Hello all, My plants were viciously attacked by red spider mite and mealy bug last year. I went down to Chelsea last week and a Rentokil rep. told me I should use an organic insecticide based on rape seed oil for the spider mite or a v. expensive product called IMIDOCLOPRID - loose or in Levingtons called ' intercept compost' . I rang around some of my local garden centres and no one stocked it. Does anyone know where it is available ? I live in the Manchester area. Thank you David +More -- David Thornton Manchester (u.k) zone 8b Homepage http://www.dave-aroid.demon.co.uk

Instead look for a new plant spray called Provado Ultimate Bug Killer which is a mix of imidocloprid and methiocarb and is the first spray I have ever had success with in killing spider mites. It is very effective and systemic also. Its brand new so again you may have to search, look for a yellow and blue can with blue cap. Hope all is well with you. Its made by Bayer and they have a website so maybe that will help with distributors: www.bio.uk.co or call: 020 8344 6808. Best wishes, Geoffrey Kibby

Thanks for the advice about Provado Ultimate Bug Killer. I had no trouble finding it at DIY chains. It's been effective against mealy bug but the spidermite is still a problem. I bought some Phytoseiulus predators, though there's still probably residue from the spray. I remember that you are interested in entomology ? Have you tried them ?

I have lots of plants in my flat (= apartment for all those in the US!) where I am more reluctant to go spraying insecticides around (my flatmates complain.....). So I figure Phytoseiulus should be the answer. I have a number of commercial growers as friends so should be able to get a sample from them to try. The thin leaves of Remusatia in particular seem to be exactly to the red spider's taste! Anthuriums fortunately dont seem to suffer as much. Regards, Geoffrey

From: Dan Levin levin at pixar.com> on 2001.07.09 at 14:28:28(6993) Don, Straight imidacloprid is available here in the states. It is registered/ labeled as Merit 75 WP and is available in 2 oz. plastic bottles. It's also packaged in granular form for turfgrass applications. Costlier than other products but it goes a long way (dilution for ornamentals 1 tsp: 10 gal = 1.4 g: 38 liters). As an aside, imidacloprid is also labeled as Primise for the US pest control industry and has become a popular replacement for chlordane when treating soils for subterranean termites. I've used Merit with good success on a wide variety of aroids & other misc. plant families with no problems noted. It's a relatively safe systemic with low toxicity to non-target organisms including people & animals, and has good to very good persistence in the plant. However, it is not labeled as a miticide. Don't personally know if Provado Ultimate spray is available over here, but based on the fact that methiocarb aka "Mesurol" has become much harder for homeowners/hobbyist growers to obtain (no longer EPA registered for food crops in the US); I'd be surprised. -Dan +More p/s to David Thornton: Your spider mites would only be stopped by the methiocarb portion of Provado spray and it's important to note that methiocarb is NOT a systemic. It kills predominantly by contact activity. IF you opt to spray again, keep in mind you'll need to coat all surfaces thoroughly for effective mite control.

I've been using the product, Marathon, with good success, but I was just wondering if there was a "contact type" of product available. -- Don Martinson +More Milwaukee, Wisconsin Mailto:llmen@execpc.com

From: magrysbo at shu.edu on 2001.07.10 at 03:37:18(7004) Don, I've seen a Bayer product in the type of bottle described at Lowe's and Home Depot. I don't know if it's the compound being discussed, but its described as a once-a-year systemic for trees and shrubs that is watered in. +More BTW: Arundo looks now like 2 variegated corn shoots coming up. When do I get to move the overhead power lines? I'll be thrilled if I have to!
