Pre-bud break liquid lime sulfur or Sulforix for the prevention of anthracnose and phomopsis starting early in the season. 2. & 3. The pre-bloom and post-bloom fungicide applications primarily for the prevention of black rot, downy mildew, powdery mildew, phomopsis and botrytis. 4. The final planned application at veraison. This is the one you want to have a long residual and to provide protection against downy mildew, powdery mildew and some of the bunch rots. This is where a full spectrum, systemic long residual strobiluron fungicide like Abound, Flint, Pristine, Quadris Top or Sovran works well. The pre-bloom spray is very important because of its protection of the emerging flowers during the critical period of pollination. The post bloom spray is also key because of its protection of the newly forming fruit. This is the first time of the season where a full spectrum, systemic long residual strobiluron fungicide like Abound, Pristine or Quadris Top works well for one of these applications. Depending on which strobiluron fungicide is used, it is always good to read the label and tank mix with a product that will double up with another mode of action for downy mildew and/or powdery mildew as a way to deter fungicide resistance from occurring. The strobiluron labels recommend that no two consecutive applications of their product be sprayed to deter the buildup of resistance. 2 Fungicide resistance is a real problem that needs to be managed for. It is very important to read the labels and use multiple fungicides with different modes of action and tank mixes to deter fungicide resistance. mlw Reminder: Remember to Always Read and Follow Label Recommendations. mancozeb has a Further resources: 66 day PHI a.

Loaned into Medieval Latin it found its way to the Old French word alcool. In the sixteenth century the word’s meaning evolved to cover to any sort of sublimated powder. Finally, in the mid-seventeenth century the word evolved once again to refer exclusively to distilled or rectified spirits. Herbicide Drift Response Checklist The months of May and June represent the most active period of herbicide drift incidents for vineyards in the Midwest. Unfortunately herbicide drift can have dramatic and long lasting effects when the vineyard is hit when flowering. Glyphosate (Roundup) and the phenoxy herbicides 2,4-D and dicamba seem to be the most commonly reported herbicides drifting into vineyards. Here is my recommended checklist of steps to take after discovering herbicide drift in your vineyard: 1. Identify the area affected. 2. Document the date, time and growth stage of the grapes. 3. If possible, identify the source of the drift and make a determination if you want to settle this problem between friends or foes. Note: You can click on the calendar at the bottom of the Weather WunderMap to pull up the exact weather conditions at the time of application at your location here: http://www.wunderground.com/wundermap/ 4. Contact your State Department of Agriculture Pesticide Division if you cannot determine the source of the drift and/or you want to formalize the complaint ASAP (30 - 45 day deadline in many states). Highly Recommended! Note: A third party complaint investigation report from your state department of agriculture provides key evidence and leverage when dealing with damage 3 settlements. 5. Flag a selection of affected and unaffected plants, take high resolution pictures weekly until symptoms subside and measure final yields per plant. Including a tape measure or yardstick as background in the picture will provide a good size comparison. 6. Severe injury settlements should be held off until after next season’s harvest. Photo and yield documentation should be continued. 7. Document everything, including each time you meet with the applicator, insurance claims agents and government officials. 8. Continue your vineyard best management practices during the entire ordeal. You do not want to have the perpetrator and their entourage accusing you of not taking care of your vineyard during this entire process.
