[apple-crop] FSMA vs. GAP: Overlap and where to begin?
Hi All, Has anyone tried to figure out the exact overlap between the US FDA Food Safety Modernization Act (FSMA) and GAP certifications offered by the USDA, Primus and others? I'm interested in finding or making a checklist that outlines what else an apple grower who is ALREADY GAP certified needs to do to be in compliance with FSMA. This NSAC flow chart can help you determine if you are exempt: http://sustainableagriculture.net/wp-content/uploads/2016/02/2016_2-FSMA-Fin al-Rule-Flowchart-V3.pdf Any thoughts?

[apple-crop] MaluSim Carbohydrate Model for non NEWA users
Hi All, I am looking for the MaluSim model in a format that does not require access to a NEWA station. The closest NEWA or EnviroWeather station is over a 100 miles from several growers we work with. We would like to use the MaluSim carbohydrate model but cannot find any information on how to manually calculate carbohydrate loads and balances using our on-farm weather data. Does an Excel spreadsheet exist that would allow us to input weather parameters from our on-farm stations? The NEWA stations make it very easy, but all the articles discuss that accuracy of weather data is essential for this to work and I am concerned about how appropriate it would be to use carbohydrate predictions from over 100 miles away. Phil Schawllier's Predicting Fruitset Model spreadsheet is perfect, http://extension.umass.edu/fruitadvisor/resources/clements-corner! Now I just need an Excel sheet that can do the same for the MaluSim carbohydrate model. Any thoughts or suggestions?

Re: [apple-crop] Sprayer Calibration Between Training Styles
Hi, As travel speeds increase, this may increase turbulence, increasing potential for drift, you also may not like the coverage you get. Sounds like Nick has older plantings and newer high density, so a slower speed may be needed on the older trees. We completed spray coverage analysis with water sensitive cards last year in a tall-spindle orchard that was being sprayed at 4mph and every-other-row. Results showed variable coverage on the row being sprayed and no coverage on the opposite row, especially on the back sides of the leaves. Dr. Andrew Landers, Cornell, discusses the role of travel speed and fan speed to achieve spray penetration and coverage in his book, Effective Vineyard Spraying A Practical Guide for Growers. This resource should be on everyone's shelf.

[apple-crop] dogwood borer management with Assail
Hi All, I have a grower who has had an ongoing issues with dogwood borer and would like to identify an alternative to chlorpyrifos. Does anyone have experience using Assail (acetamiprid) as a trunk drench to manage dogwood borer infestations in burr knots on Mark rootstocks? How effective have those treatments been? Assail 30 SG is labeled for a trunk drench. Mounding soil over the burr knots is not economically viable considering the acreage. Chlorpyrifos can be used up to 28-days before harvest for dogwood borer and would like to see that only as an option if we can't identify lower-risk alternatives. Thoughts on this?
