Anyone willing to sell a smaller quantity of indar? EDIT: and discussion of other brown rot solutions for apriums

Trying to figure out what to buy this year. Unearthed the two quotes below and likely going with captan +something (or maybe more than one something).

Most of what I’ve read has said you should mix a protectant (Captan) with a Group 3 (propiconazole, indar). And that does seem to be the least expensive but max 5 sprays for prop. according to what I’ve found. So quote 1 makes sense.

I found tebuconazole with brand name Toledo 45WP and it seems very inexpensive. (also group 3, also cannot be used too much - if used at lower rate maybe 6 sprays). So maybe that.

Has anyone tried Topsin-M + Captan? Topsin-M suffers from the “only large quantities” problem in that it comes in 1lb dissolving packets but my calculations show I’d only need .5lb per spray. However, it is listed for peaches, apples and pears (which is one of the things that @alan pointed out which is important to me since I have multiple tree types). And it seems less expensive but has good ratings for brown rot when mixed with captan… and it’s not a group 3.

@Olpea

If brown rot pressure is high, it’s not unusual to tank mix a couple fungicides. Captan is a good all around fungicide for most stone fruit. I don’t grow apricots anymore, but my understanding is that Captan only has a negative reaction with the fruit of apricots (mostly once it gets close to harvest) not the foliage.

Early in the season, we use the full rate of Captan, Then we generally reduce the rate and add a DMI like propiconazole, or Indar. Once we get closer to harvest, we completely do away with captan and just use a DMI (Indar, etc.). If pressure is super high, we might use a combo premix like Inspire Super.

@Olpea

Indar has run roughly $12 per acre/application in the past, but it is much more expensive per bottle (over $300 per gal).

Propiconazole is cheaper still on a per acre basis, but the label allows fewer applications and it doesn’t work as well as Indar.

Hence I am interested in tebuconazole (as jaypeedee mentioned) which may be another affordable option, as a replacement for one of these other azoles (DMI’s)
