Hi Peter,

This is the proportion of insecticides that I use bi-annually per 1 Gallon (U.S.). It works great for me but I believe that Dean uses a slightly smaller amount of TetraSan 5. I based this on Dr. Stock's past post but, I can't locate his formula, offhand, in the topics :x .

PER GALLON:
3/5 teaspoon TetraSan 5
1/8 teaspoon Merit 75 WP
1/2 teaspoon Enstar II

I always mix the TetraSan first, in a small jar of HOT water by shaking it repeatedly, because it will not dissolve completely in cold or lukewarm water.

Peter, Jim; Iuse 1/4 teaspoon of Tetrasan/gallon but Jims overall formula sounds ok. I have had no problem with tetrasan in 70degree F water but it won't hurt to warm it up a little to dissolve it better.

Jim, where do you purchase your Tetrasan, Merit and Enstar. I've been looking for a supplier where I can get all three. TIA

Hummert international. They have a website ( I believe it is Hummert.com).

Hi all -

A friend has problem with scales. I told him that I remember reading that Merit will work on scales as well as mealy bugs. Is this correct?

Peter

Yes, the Merit will work and so will the Enstar.

question for tetrasan users... I purchased it recently tetrasan 5wdg and received 2oz bags designed to be dissolved in 10 gals of water. Do you open the bag and use 1/4 tsp to a gal of water or do you dissolve the entire bag in a gal of water and use a tenth of the concentrate to gal of water? And of course using the proper PPE.

Thanks...

I believe that either method would work but storage of the dry powder is much better. The mixed solution would go downhill is a few weeks. I put the small bags into a plastic baggie and carefully slit the bag with the tetrasan. It is in small rod-like granules rather than a dust so it is easy to use this way. I simply go into it with metal measuring spoon for what I want and then reseal the baggie. In practice I also put the baggie with the opened bag of tetrasan into another larger baggie so it is double bagged. Store it is a dark and relatively cool place away from children and pets. I use a small locked storage locker for my insecticides and fungicides.

Thanks Dean, I plan on treating my plants this w/e. Had treated with neem oil and felt that I was making some head way, but feel the need to hasten the process.

I hope Dr Stock answers but I've been using this mix for a while, thanks to Dean.
My mix, well I'm always confused.
Enstar II .5 ml – 3.0 ml / 1 gal

Tetrasan 2.27 grams - 4.54 grams / gal

Merit 75 WP 0.35 grams / 1 gal
(Dean Stock uses 1 tsp = 1.4 grams/gal of Merit)

Dean is this right? 1tsp / gal. That's a lot more than I have been using and more than recomended. I have mealy bugs. Not a lot but some.
I started using this mix 2 years ago and my mite problem is gone. Thank you Dr Stock.
Dan

Sorry Dan, I didn't notice this earlier. I use Tetrasan at 1/4 to 1/2 tsp/gal; Enstar at 1/2 tsp/gal and Merit at 1/8 tsp/gal. I woudn't use Merit at 1 tsp/gal as it takes very little of it to be effective.

I know this has come up before, but for the small hobby grower is there any way to obtain considerably smaller quantities of these? I don't think I'll LIVE long enough to use even the smallest quantities listed by Hummert, etc, even if I HAD several hundred $ to put into chemicals I'd probably have to mention in my will... :roll:
