Upcoming Altacor Changes
This is shaping up to be a dynamic year for chemical manufacturers. Detail from FMC on Altacor is included in this post. Loveland products has discontinued Diazinon 600. Detail from Adama on their two Diazinon formulations (Diazinon 500, and Diazinon 50W) will be released in July.
A change is coming to the popular fruitworm control Altacor—luckily FMC has the same active ingredient available in Altacor eVo, which is listed for cranberry. Many suppliers still have sufficient stock of Altacor available for this season, but growers will want to familiarize themselves with Altacor eVo for coming use. Altacor eVo is a more concentrated form of chlorantranilprole than Altacor, so your use rate will decrease in order to apply the same amount of active ingredient to the crop. Thorough mixing and even coverage become all the more important with increased concentration formulations.
