Historically, the following statement appeared at the beginning of the peach calendar in Publication 360: “All products labeled for use on peach can also be used on nectarine.” During the summer of 2016, an auditor spotted Decis on the spray record of a nectarine grower and flagged it as unregistered. After a lot of emails, we received confirmation from PMRA that, indeed, if a product label does not specify nectarine or Crop Group 12-09, it is not legal for use on nectarine. This prompted a search of all products labeled on peach to see whether nectarine was included. The following table gives the updated list of products that are not labeled on nectarine. Products that are in bold with yellow highlight now have label expansions and can be used on nectarines.
|Product name||Registration number||Common name|
|Decis 5 EC||22478||deltamethrin|
|Imidan 70-WP Instapak||29064||phosmet|
|Purespray Green Spray Oil 13 E||27666||mineral oil|
|Superior 70 Oil||9542, 14981||mineral oil|
|Guardsman Copper Oxychloride 50||13245||copper oxychloride|
|Copper Spray||19146||copper oxychloride|
|Ferbam 76 WDG||20136||ferbam|
|Maestro 80 DF||26408||captan|
|Microscopic Sulphur WP||14653||sulphur|
|Thiram 75 WP||27556||thiram|
Also note that Thionex is no longer labeled on peach after Dec. 31, 2016 and Sevin XLR is no longer registered for use on apricot, cherry, grape, peach, pear, plum
OMAFRA will be working with the companies and PMRA on label expansions for the most critical uses. For the time being, none of these products are legal to use on nectarine. As we make progress, further updates will be released.
