Please make sure to read the label. It is typically in the range of 3-4 pints per acre and assuming 100 gallons (not 10) of water to be used per acre. Some products gives you a percentage (or ratio of the product and water) that you should aim for too. Once again, the ratio will differ depending on the product, so, make sure to read the label. <br /><br />You can mix captan and sulfur with a phosphite.Mizuho Nitahttps://www.blogger.com/profile/10877092875033606750noreply@blogger.comtag:blogger.com,1999:blog-7758013995487504560.post-8171226745978138612018-05-18T11:37:36.800-04:002018-05-18T11:37:36.800-04:00Question: Several years ago, I applied phosphite ...Question: Several years ago, I applied phosphite at a rate of 4-8oz/gallon based on the direction of "2.5-5 pints per 10 gallons per acre". My vines reacted very badly. I was later told I probably should have used 0.5-1 oz per gallon. I have not used phosphite since, but with the recent persistent rains I am considering an application again. Can you please advise on the correct dilution? Also, can Captan and Sulfur be applied at the same time? If not, within how many weeks? Anonymousnoreply@blogger.com
