Someone can correct me but the math is:
24 ounces (1.5 pounds) x .01 = .24 and I rounded to .25
So .25 ounces per gallon = 1.5 tsp per gallon as a liquid fungicide.
I don’t know if it would be the same for dry measurements. One would think yes but I’m not sure.

I think I have understood from Olpea that liquid and dry don’t equal. I have a small scale on order, I will measure out one ounce for 4 gallons which is the size of my backpack sprayer and see how many tsp/tbsp it equals. Thanks for the reply.
A guide from the University of Kentucky that has spray rates per gallon for some commercial insecticides/fungicides including Imidan, Lorsban, Ambush, etc.

Thanks, I put that in the wiki. Too bad they don’t have a similar liquid chemicals page, its dry powders only

The rate for Ziram 76DF is around 6 pounds/acre for apples. The 1 1/2 pound rate for 100 gallons on the label comes from an assumed 400 gallon per acre spray rate and may be too low if you are not spraying 400 GPA.
For comparison purposes the rate for Captan 50WP is about 6 pounds/acre too (4-8 pounds/acre on label) so if you have determined the proper rate for Captan then the rate for Ziram should be about the same.
Ziram is very dusty when mixed just like Captan and can cause sever eye damage so I always wear eye protection. Same for Captan 50 WP.
I use Ziram on peaches some. For peaches the max rate is 8 lbs. per acre. At a full dilute spray of 250 gal/acre that would equate to about 1/2 ounce of Ziram per gal of water.
I haven’t weighed Ziram to find out how it converts to a volumetric measurement like teaspoons or tablespoons.
I was looking at ordering Imidan from Keystone, and saw they no longer ship it. Now has to be shipped haz-mat.

Bound to happen eventually. Avaunt works well for PC and most other common apple pests and is a lot easier to handle. The label says can only be used for agricultural applications, which means you have to “plan” to sell some of your crop- I believe that’s the extent of it. It’s not restricted last I checked.
Does anyone know the ratio of Luna Experience to mix - per gallon of H20?
I am dyslexic with anything to do with numbers . . . and dismal at math computations beyond basic stuff - and don’t know how to do the computations. 
Please - no lectures . . . . just the amount to add to a gallon of water. Thanks.
I found Pestrong to be a bogus company and worked hard to get my credit card company to cancel payment when delivery didn’t come and they failed to respond to my complaints. Maybe they have changed- that was at least 2 years ago. Their relatively low prices tempted me to try them, but sometimes cheapest is the most expensive. Keystone is reliable.
This post may be spam.
Sure looks like it, thanks for the heads up Alan.
I did a quick google. Pestrong has bad reviews and looks pretty sketch.
Agcareproducts.com looks to have decent reviews based on 159 google reviews.
I purchased Imidan from them, and didn’t have any problems. I did contact them first to make sure that they had the product in stock. I think that they run into problems with inventory management.
Not spam. So much for trying to help people find product.
I might agree a little that Pestrong may be a company that you want to be on your toes dealing with. I think that they get in trouble by taking orders for products that they do not have in stock. I have not had a problem dealing with Pestrong when I called first to make sure that they had the product in stock. Customer Service is not their strong point. They seem to have an attitude at times. But they shipped Imidan to me at a reasonable price when I couldn’t find any one else who would.
Keystone may be reliable, but tends to have a higher price (especially if you purchase from them on ebay instead of on the Keystone website). I find that Martin’s Produce Supply (https://martinsproducesupplies.com) is another firm that usually has cheaper prices than Keystone, and is a family-owned business.
I thought you original comment was spam brought by Pestrong because you joined the forum right before posting it. I’m glad I was wrong and appreciate your contribution here. Welcome!
I notice that Martin’s doesn’t list Captan or Indar among the products they sell in their website. Rally was about 6 bucks cheaper than the Keystone price, but I didn’t check shipping and handling costs, which can drive up prices substantially. How long do they take to deliver- Keystone is pretty quick and shipping costs are reasonable.
Why would you buy from Keystone through E-Bay? That wouldn’t be the normal approach for me.
As far as delivery times and shipping costs go, Martin’s has been similar Keystone’s for me. Both are relatively close to me, so that may vary for more distant locations
Thanks, I actually far prefer granular Captan (much longer shelf life after opening and there’s always going to be some left over at the end of the season) but try finding those things from their website. Not sure what you did differently. I tried their search app. unsuccessfully.
They have 6 1/4 lb bags of granular captan, click on the "choose an option link on their captan page.
