  Insecticides
From: David Thornton dave at dave-aroid.demon.co.uk> on 2001.05.28 at 19:21:07(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

Dave,
The soil mix with imidocloprid is quite hard to find even in the London area.
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

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.

Thanks, Dan. 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,
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.
