Captan Shortage

I have heard rumors of a potential captan product shortage, and based on information that is coming in from the field, it appears to be true. I am not sure of the details as to why we have a shortage of captan in the marketplace, and I have no information as to when the shortage will be alleviated. However, the good news is that thiram products, assuming you can readily obtain these fungicides, are pretty much a straight plug-in for captan products relative strawberry disease control. Thiram is probably not quite as active as captan for anthracnose, but it is close. Of course, other products are also available for the multiple diseases that occur on strawberry, but captan and thiram mainly address Botrytis and anthracnose diseases; fungi do not readily develop resistance to these fungicides, so they continue to provide an important backbone for our spray programs. As always, please contact your local extension agent if you have questions concerning this or other issues with strawberries. The IPM guide for strawberries can be found at the link below.
