Clusters with leafroll


Grapevine Leafroll Disease Control: It Pays to Test Neighboring Vines (pdf)
The economics of grapevine leafroll control through vine replacement has a spatial component.  A new model by Shady Atallah and Miguel Gomez demonstrates that testing vines adjacent to those with leafroll symptoms and replacing them if they test positive increases expected net present value by 19%.

Extra buds


How well did winter bud injury measurements predict the final grape crop?
Cornell Cooperative Extension grape programs estimated midwinter primary bud injury in March, and  surveyed vineyards  in July to estimate cluster counts and potential crop.  Despite significant bud injury, the 2014 crop was only modestly reduced.  Many growers left extra buds, which was a successful strategy in limiting losses from winter injury.
