Apply Topsin M as a paint or directed spray to wounded surfaces after pruning and before the next rain. This recommendation is primarily for large pruning cuts, but has been shown to be beneficial under such conditions.
Apply Mettle as spray withing 24 hrs after pruning (12hr REI).

Sanitation - Remove all dead wood, infected wood and pruning stubs, mummies or other overwintering material that may harbor inoculum from the canopy during dormant pruning operations. Canopy management - Prune and train the vines to promote air circulation and speed drying of the shoots and clusters. In some instances performing “cane pruning” rather than “spur or cordon pruning” in vinifera and hybrids will result in ensuring new wood is laid down on the fruiting wire every year. Vineyard management. Orient rows to improve air movement within the vineyard. |
Badge, NuCop, Champ and other copper products may cause slight to severe foliar injury to certain varieties. Use on a small area first to confirm lack of sensitivity before treating large areas. Read label carefully for cautions.
Do not use Flint, Inspire Super, Pristine, Quadris Top, or Revus Top, on Concord Grapes (or related varieties) as injury may occur. Read label carefully for cautions.

Strobilurin fungicides (Abound, Quadris, Sovran, Cabrio, Flint, Pristine, ) can be very effective on Black Rot, but are highly susceptible to developing resistance in the target organism and so are best saved for later in the season for high need situations.
Abound and Quadris both contain azoxystrobin and are highly toxic to apples. Do not spray grapes near apples or use the same equipment that will also be used on apples to avoid injury. Do not use Flint, Inspire Super, Pristine, Quadris Top, or Revus Top, on Concord Grapes (or related varieties) as injury may occur. Read label carefully for cautions. NuCop, Champ and other copper products may cause slight to severe foliar injury to certain varieties. |

Immediate pre-bloom through early post-bloom are the most important times to control Black Rot and where this disease has been a problem and in highly susceptible cultivars, this is a critical time to manage this disease.
Prune and train the vines to promote air circulation and rapid drying of the leaves and fruit. Establish new plantings away from wooded areas, where wild grapes can serve as a source of black rot spores.
|
CAUTION: Do not use Abound, Azaka, Quadris Top, Sovran or Topguard near apples or with equipment that is also used to spray apples as severe phytoxicity may result.
CAUTION: Do not use Revus Top, Pristine, Quadris Top or related materials on Concord or related cultivars as damage may occur.

This is a critical time to achieve control of this disease especially on highly susceptible cultivars and where high levels of inoculum are present from the previous year. Spray applications should be made to every row and rates adjusted upward to get good coverage on larger canopies.
Be sure to rotate chemistries (FRAC Groups) to avoid the development of fungicide resistance to this disease in your vineyard.

This is a critical time to achieve control of this disease especially on highly susceptible cultivars and where high levels of inoculum are present from the previous year. Spray applications should be made to every row and rates adjusted upward to get good coverage on larger canopies.
Be sure to rotate chemistries (FRAC Groups) to avoid the development of fungicide resistance to this disease in your vineyard.
|
CAUTION: Do not use Abound, Azaka, Quadris Top, Sovran or Topguard near apples or with equipment that is also used to spray apples as severe phytoxicity may result.
Group 11 materials labeled for DM should be used with care during this time to avoid the development of resistance.
CAUTION: Do not use Revus Top, Pristine, Quadris Top or related materials on Concord or related cultivars as damage may occur.

Sanitation - Remove all dead wood, infected wood and pruning stubs, mummies or other overwintering material that may harbor inoculum from the canopy during dormant pruning operations.
Canopy management - Prune and train the vines to promote air circulation and speed drying of the shoots and clusters. In some instances performing “cane pruning” rather than “spur or cordon pruning” in vinifera and hybrids will result in ensuring new wood is laid down on the fruiting wire every year. Vineyard management. Orient rows to improve air movement within the vineyard. |
This spray is critical in vineyards or on varieties (especially French hybrids or Vinifera) where Botrytis bunch rot has been a problem.
Do not use Flint, Inspire Super, Pristine, Quadris Top, or Revus Top, on Concord grapes (or related varieties) as injury may occur. Do not use Intuity on V. labrusca or hybrids where sensitive is not known. Read label carefully for cautions.
Only 1 application of Meteor per season allowed on table grapes; 4 applications allowed on wine grapes.
Be sure to rotate materials from different FRAC groups to avoid promoting fungicide resistance development.

Classify vineyards as low, intermediate, or high risk of grape berry moth attack. Find Risk Assessment information here. High- and intermediate-risk vineyards receive insecticide treatment at this time. This spray coincides with peak egg-laying of GBM which, in most years, occurs 7-14 days after the mid-bloom period. Good spray coverage of the clusters must be achieved to control grape berry moth. The Cornell Organic Production and IPM Guide for Grapes provides information for organic growers. Vineyard Management - Avoid sites prone to heavy snowfall or those surrounded by wooded areas. Where possible, plant rows parallel to wooded edges to allow for spot treatment of outside 4-6 rows. Biobit and Dipel are Bacillus thuringiensis (Bt) kurstaki products. Apply two sprays per generation, 7 days apart. Use Venom or Scorpion for 1st & 2nd generations only. |

Use of traps is not recommended as they often draw this pest in from remote locations outside of the vineyard and increasing damage in the vineyard.
Mature vines can sustain significant amounts of feeding injury without yield or quality impact. Young vines are the most vulnerable to injury from heavy feeding that can delay the establishment of the vine or even cause vine death. Be sure to check for feeding inside grow tubes in newly planted vineyards. Remove tubes and treat if found. Danitol and Brigade are broad spectrum insecticides and may disrupt populations of beneficial insects and predators such as mite predators resulting in increased pest populations.
Surround may leave visible residue on leaves. Neemix and Aza-Direct act as anti-feedant and may require frequent reapplication; see label for specific recommendations. Be aware of pre-harvest restriction on some recommended materials. |

This is an important time for controlling Downy Mildew infections.
Weather conditions will dictate fungicide choice, rate, and spray interval. Coverage is very important for control. Weather forecasting models can help identify infection periods for this disease. |
CAUTION: Do not use Abound, Azaka, Quadris Top, Sovran or Topguard near apples or with equipment that is also used to spray apples as severe phytoxicity may result. Do not use any Group 11 material alone; use in combination with another material to avoid the development of resistance.

This is the most critical time of year for protecting against cluster infections by Powdery Mildew.
Weather conditions will dictate fungicide choice, rate, and spray interval. Coverage is very important for control. Weather forecasting models can help identify infection periods for this disease. |
CAUTION: Do not use Abound, Azaka, Quadris Top, Sovran or Topguard near apples or with equipment that is also used to spray apples as severe phytoxicity may result.
Do not use Flint, Inspire Super, Pristine, Quadris Top, or Revus Top, on Concord Grapes (or related varieties) as injury may occur. Read label carefully for cautions. Some cultivars are sensitive to sulfur and will be damaged by sulfur sprays. Check label for cautions and see Table 55 for ratings for sensitive cultivars. Do not use Trilogy after bloom on table grapes or following bunch closure on wine grapes.
