Please read below from the Dr. Lenny Wells and the UGA Pecan blog<\/strong><\/span> about a new fungicide for pecan management in 2020<\/strong><\/span>.<\/p>\n

It\u2019s too late to help us for this year, but there is a new fungicide labeled for pecans that provides a totally new chemistry<\/strong> <\/span>for us to use in our arsenal of weapons to fight pecan scab and its performance on nut scab in UGA Plant Pathologist Dr. Tim Brenneman\u2019s<\/strong><\/span> trials has been excellent.<\/p>\n

Syngenta\u2019s Miravis Top recently received its label and will likely be a significant component of next year\u2019s spray programs. This fungicide combines difenoconazole (a group 3) and pydiflumetofen (group 7), the latter of which is a new chemistry for pecans, which should strengthen our resistance management programs.<\/p>\n

Dr. Brenneman\u2019s work has demonstrated very good results on nut scab with as much as 98%-100% reduction under heavy pressure situations. The best fit<\/strong><\/span> for the material will be in the June-August<\/strong><\/span> nut sizing period, used in rotation<\/strong><\/span> with other strong nut scab materials like Elast or Elast\/Tin<\/span> <\/strong>combinations. It is recommended to use no more than 2 sequential applications. The rate will be 13.6 oz\/acre.<\/p>\n

As with any fungicide we strongly urge growers to rotate these materials<\/strong><\/span>. The key to helping all our fungicides work better and longer is to continuously rotate them and not rely too heavily on any one material.<\/p>\n

Photographs below show one example of the results of Miravis Top on Wichita<\/strong><\/span>, one of the most highly susceptible scab varieties.<\/p>\n
