Malathion Rate
 

Hi, I wish to control scale on my Bay Tree with Malathion.
What is the mixture rate to use.
Do I need to mix it with while oil for it to be effective.
Thanks
Mark

zero malathion. 2TBS oil, one gallon of water

I'd never use such a toxic poison, and I'm sorry, but you are a poster boy for
why we have to terminate these homeowner pesticides. READ THE LABEL. The label
tells you everything you'd need to know how to use this tremendously deadly
poison.

Why did you choose malathion when Sunspray oil, or insecticidal soap would be
far more effective than malathion?

It's not that deadly to mammals! Humans are in little direct danger
from it - that isn't the problem.

Well, I agree that malathion isn't a good choice, not least because
scale insects tend to be resistant to it, but insecticidal soap is
only a little more effective. Much less nasty, of course.

On pot plants, scraping is the best solution, but that might be
impractical on a large bush. I have heard that oil sprays do
work, but the effective ones aren't exactly non-toxic.

Sunspray Oil is not a poison, it's a contact pesticide.

A dormant oil spray, mixed at the 1/2 strength "summer oil spray" rate
would be more effective, but iirc you should not use oil spray when the
temperature is about 90 F. degrees. There will be directions on the label.

That's why they invented SunSpray. It's a horticultural oil which you can use
in any season. I live in Texas and have used it to treat a horrific scale
problem on one of my redbuds.

I agree, it is not very toxic to humans as it is readily broken down in the liver.
It is also rapidly biodegradable. However, anyone with a compromised liver had
better give it a pass. I dont think it is very effective against scale, however.

For the original writer, one cannot ask a question here some days without a
landslide of rudeness coming at you. What is the purpose of this arrogance and
cursing? You could just be silent if you are unable to countenance a comment.
Here is one side from an owner of Laurus nobilis or the bay tree. Malathion
is the same family of chemicals as Lindane. Lindane is what the doctor paints
your kids with if they come home from school with scabies. If you take a cruise
and put a patch behind your ear for mal-de-mer, it is an organo-phosphate.
Neither is a human disaster used in small quantities though the Malathion won't
cure the scale problem on just one try. These are organo-phosphates, a term
with organic gardener problems. The term sets off numerous uninformed
speeches. The same pesticide free gardeners use other chemicals making them
pesticide users usually condoning their practice by using one that is an old
product and therefore harmless. Nicotine, arsenic and copper sulphate were
favored for years. If you plan to use the bay leaves for home cooking, you
would want to use a pesticide formulated for vegetables.

The oil won't do the job either and will make a mess for you that is not
pleasant indoors. Scale occurs all year around. What we do with our bay tree
is be quite vigilant and clean off the scale physically with very small foam
paintbrushes soaked in alcohol followed with a soap (any dish soap) and water
bath. Leaf axils of the plant are hard to clean. This is not failsafe so you
will need to watch and repeat. The first stage of the scale insect is nearly
invisible so it is a difficult problem on a large plant. Scale prefer other
plants to bay trees so you usually do not get a heavy infestation.

On both the bay tree and on large citrus when scale infestation is heavy you
can completely defoliate the tree, every leaf. Then you can scrub the barked
over parts with a soapy solution of any pesticide you like. You do this on a
heavy layer of newspaper with the plant lying on it's side. Discard the
newspaper. In a cool sunny spot the tree will refoliate and if no other plant
in your collection remains to reinfect the bay, it should be clean. Keep Ficus
out of your indoor collection, it is a scale magnet.

See
http://www.fda.gov/cder/drug/infopag...lindanePHA.htm for the
FDA's current recommendation on the use of Lindane for treating
scabies and lice. It's still approved for use with qualifications,
but they certainly don't view it as benign.

I do agree with you that people who post sincere questions here should
be treated with respect. It makes much more sense to educate than it
does to berate.

The original poster never said the bay tree was indoors.
Malathion *can* be used to control scale insects, but only if you get them
before they form a hard waxy shell. After that, a summer weight oil spray
is the best treatment, unless you wanna use a systemic (like cygon) or pick
the insect off by hand as you do. I've used oil spray to kill scale on
gardenias (or was it camellias?) and it is effective.

I don't think I'd use cygon on a bay tree if I planned to use the leaves
for cooking. It's probably safe enough -- it's not like you'll make a big
salad exclusively of bay leaves -- but it still seems wrong somehow.

Bob

This among the many idiocies in your post stands out. No one considers
these products organic. To bad you live in conditions where you have
to use organo-phosphates on your kids, many of us do not.

You really haven't much of a clue about the effective use of oil as an
insecticide. I've controlled scale for years in large indoor and
outdoor collections with oil, as have many others committed to good
cultural gardening practices.

Malathion
is the same family of chemicals as Lindane. Lindane is what the doctor pain

Acrually, Lindane is a chlorinated hydrocarbon(organo-chlorine) and malathion
is an organo-phosphate. They both have the same mode of action but are from
different chemicalgroups. Either way, using anything other than horticultural
oil on scale is sort of a waste. You could pick them off but it takes forever.
