We promised to publish your comments on the last article on Napropamide. Your honest opinion is welcomed, and we understand that sometimes your views and experiences will differ from ours.
You have reported that uniformity of broccoli harvesting was affected by the application of Napropamide. Having too many harvesting events can obviously increase the cost of your operations.
Thank you for communicating this to us. According to some authors in crops such as wheat yield can be improved by minimizing plant-to-plant variability in seedling emergence1. We value your perspective as we are all working for the benefit of the industry.
The evaluations conducted at the UA Yuma Agricultural Center were not taken to harvest and therefore no crop maturity data was collected this season. Hopefully will do this in future trials.
Other comments:
“Thanks for the Devrinol trial work. I had almost forgot about this material. We used to use it on Cantaloupe and Tomatoes up here years ago. I recall one experience where a new grower used it under plastic and suffered high plant stunting and death. In most cases in open furrow production, it worked great”. –PCA/Grower
“I reduced the rate to 1pt and worked good”. --PCA
Note on Dacthal
We wanted to share some information on the revision of the registration of DCPA.
On April 1, 2024 the EPA published new information on Dacthal here: EPA publication on DCPA released yesterday. It was a warning that has been posted in various web sites.
Previously on March 27, 2024 response (EPA-HQ-OPP-2011-0373-0112) to the registrant the EPA says the following: “Given our inability to identify and agree on a mitigation strategy that addresses EPA’s concerns, the agency is currently exploring the regulatory options available to it under FIFRA Section 6. Due to the serious potential risks posed by DCPA use, EPA will be pursuing these regulatory options as soon as practicable.” Therefore, we are awaiting final decision.
Some members the industry are expecting this herbicide to be available this season. The Vegetable IPM Team encourages you to check the latest information following the link :https://www.regulations.gov/docket/EPA-HQ-OPP-2011-0374/document?postedDateFrom=2024-04-01&postedDateTo=2024-04-03
Thank you very much for your comments they are very useful and beneficial for the industry.
