5.2.11 MIDSUMMER SPRAYS (July and August, as necessary) |
Black rot | For some time, it was thought that berries remain highly susceptible to black rot until they reach approximately 8° Brix. However, research has shown that even under high disease pressure, berries become highly resistant to infection by about 5 (Concord) to 7 (V. vinifera) weeks after the start of bloom. Experience has shown that it is usually possible to end black rot spray programs after the second postbloom application IF the disease has been well managed until then. However, protection may continue to be necessary until late July if more than a trace level of fruit rot is present, to limit spread within the clusters. |

Powdery mildew | Berries of highly susceptible V. vinifera varieties become moderately to highly resistant by 3-4 weeks after the start of bloom and quickly become highly resistant to immune as they age beyond that point. However, older leaves retain some susceptibility and new leaves remain highly susceptible so long as they continue to be produced. It also appears that berry stems may retain some susceptibility later in the season, although this is likely to be significant only as a cosmetic issue on table grapes. Thus, the strategy for powdery mildew management should be to provide aggressive control earlier in the season and then maintain an appropriate level of control on clean berries and new foliage during the midsummer using a less conservative approach (see "pest information" section for a discussion of this factor on different varieties). This objective often can be accomplished with sulfur later in the season on those varieties most in need of protection (vinifera and some hybrids). On Concord and some other sulfur-sensitive varieties with only moderate susceptibility to powdery mildew and tolerant of copper, copper fungicides will provide adequate control of mid-season foliar infections if needed, while also providing control of downy mildew. Many other materials that provide good control of foliar disease but are less active against fruit infections can be used effectively at this time also. Thus, this is an excellent time to use non-premium rotational materials. Most newer conventional fungicides provide a longer period of protection than sulfur, potassium salts, oils, and biological, so can be applied less frequently. |
| | Liquid Sulfur 6L | see label, rates vary | In addition to being relatively economical, use of sulfur in midsummer reduces the pressure for developing resistance to other powdery mildew fungicides.

| OR | Regalia | 1-4 qts (see label) | Regalia is a biopesticide that has provided fair to very good control of powdery mildew in NY trials, depending on disease pressure. It is likely to work best on less susceptible varieties or at times of year when pressure is low. Different rates are recommended depending on whether it is used alone or in a tank mix. Because Regalia requires 48 hours to activate plant defenses, applications need to start before infection. This product could be included in an organic spray program or in rotation before |
| | | | or after the critical powdery mildew control window (immediate prebloom and post bloom) to slow the development of resistance to other products. Regalia should not be relied on for powdery mildew control during immediate prebloom and post bloom applications. |

Downy mildew | Downy mildew often "disappears" for a while if midsummer weather becomes hot and dry, but it has the potential for "explosive" spread under favorable conditions (moderately warm temperatures and wet). Vineyards should be scouted for the presence of this disease throughout the summer, and the foliage should be protected appropriately to prevent premature leaf drop, as determined by weather conditions, cultivar susceptibility, and disease presence. |

| OR | Ranman 400SC | 2.1-2.75 fl oz | |
| OR | *NY†Zampro 4.4SC | 11-14 fl oz | *NY†Zampro is a new fungicide active against only downy mildew. *NY†Zampro contains two downy mildew- specific active ingredients: (i) ametoctradin, representing a new class of chemistry (Group 45), with no other representatives currently registered; and (ii) dimethomorph, a Group 40 fungicide similar to Revus. It is assumed to have good protective activity; some limited post-infection activity; and anti-sporulant activity. It is labeled for use at 7-10 day intervals but has provided very good to excellent control on V. vinifera cultivars whenused at 14-day intervals in several NY trials. The label allows a maximum of four applications per season, but we recommend no more than three applications of *NY†Zampro and Revus (or Revus Top) combined, and no more than two sequential applications of these products before rotating to a product that does not contain a Group 40 material. |

Botrytis bunch rot | Most commonly a problem on tight-clustered French hybrid and Vitis vinifera cultivars. Proper timing and thorough spray coverage are essential for good control. Removal of leaves around clusters soon after fruit set also aids significantly in control. Botrytis sprays should be directed towards the fruit, using sufficient water to ensure thorough coverage. Although weather plays a large role in determining the most important application times for Botrytis fungicides, sprays at or shortly after veraison consistently appear to be beneficial on susceptible varieties unless preharvest weather is especially dry. A subsequent application also can be beneficial on highly susceptible varieties if the preharvest weather is wet, particularly if the disease is already established; this preharvest spray should be at least 2 weeks after the veraison spray, and its precise timing should be determined by weather conditions, the presence of disease in the vineyard, the time remaining until harvest, and label restrictions. Applications at late bloom and pre-bunch closure can be as important as those at veraison and preharvest if the weather is wet during these earlier periods. Thus, growers who have had trouble controlling Botrytis when they have delayed applications until veraison (or later) should consider protecting against the disease at late bloom and/or pre-bunch closing if the weather is wet during these times. Resistance Warning: All of the most effective Botrytis fungicides are subject to resistance development; therefore, they should be used in rotation with each other to minimize this risk. Make no more than two applications per season of any one material or class of fungicide, e.g., Vangard and Scala are both in the same class (Group 9) and Inspire Super and †Switch each have a (Group 9) component; *NY†Miravis Prime and †Switch each have a Group 12 component; *NY†Intuity and Flint Extra are both in the same class (Group 11) and Pristine has a (Group 11) component; Endura is in (Group 7) and Pristine *NY†Luna Experience, *NY†Luna Sensation, and *NY†Miravis Prime each have a (Group 7) component. |
| | Rovral Brand 4F | 1.5-2.0 pt | 7 day PHI. Performance of Rovral and generic iprodione products usually is improved by adding oil or a surfactant to the spray mix. |
OR | Vangard WG | 10 oz | 7 day PHI |
| OR | Inspire Super | 16-20 fl oz | A rate of 20 fl oz/A of Inspire Super provides the same amount of cyprodinil, the active ingredient in Vangard, as 7 oz/A of that product. From veraison onwards, it is likely necessary to tank mix with an additional 3 oz/A of Vangard or another Botrytis-active fungicide to obtain best control, especially under high disease pressure. |
| OR | Elevate 50WDG | 1 lb | 0 day PHI |
| OR | Endura 70WG | 8 oz | |
| OR | Scala 5SC | 18 fl oz | 7 day PHI |
| OR | Flint Extra | 3.5-3.8 fl oz | 14 day PHI. Labeled for control of Botrytis at higher rates than used for powdery mildew control. High risk of resistance development and resulting poor performance in vineyards where Group 11 (strobilurin) fungicides have been applied for a significant length of time. Research in VA has shown Botrytis resistance among the strobilurin (Group 11) materials to be common there; thus, it is also likely to occur in many NY and PA vineyards where these products have been used more than occasionally for a number of years, although this has not been investigated specifically. Nevertheless, based on our experiences withdowny and powdery mildews, it is risky to rely on Flint Extra for control of Botrytis in vineyards with a significant history of strobilurin use, unless it is tank mixed with another product with good efficacy against this disease. |
| OR | Pristine | 18.5-23 oz | Pristine is only fair against Botrytis at the rate of 8-10.5 oz/A commonly used for other diseases, but it traditionally has been good at 12.5 oz/A and very good to excellent at 18.5-23 oz/A. |
| OR | *NY†Luna Experience | 8.0-8.6 fl oz | Although a lower rate of *NY†Luna Experience is registered for control of powdery mildew, the 8.0-8.6 fl oz/A rate will provide more reliable Botrytis control late in the season. |
| OR | *NY†Luna Sensation | 7 fl oz | *NY†Luna Sensation is another newer product with the same fluopyram active ingredient as *NY†Luna Experience, but combined with trifloxystrobin, a traditional strobilurin (Group 11) fungicide. Unlike *NY†Luna Experience, both active ingredients have good to excellent activity against Botrytis. The 7.0 fl oz label rate for Botrytis delivers a fluopyram dose about equal to 8.6 fl oz of *NY†Luna Experience and about the same amount of trifloxystrobin as 3.5 fl oz of Flint Extra for good to excellent Botrytis control. CAUTION: Do not apply this product to Concord grapes or injury may occur. |
| OR | *NY†Miravis Prime | 10.3-13.4 fl oz | *NY†Miravis Prime is a combination of a new succinate dehydrogenase inhibitor fungicide (SDHI, Group 7) and fludioxonil (Group 12), introduced about 25 years ago for Botrytis control. Fludioxonil is also found in another combination product called †Switch for Botrytis control. Most, if not all of the activity against Botrytis comes from fludioxonil. The 10.3-13.4 fl oz rate of *NY†Miravis Prime delivers the same amount of fludioxonil as the 11-14 oz label rate range of †Switch. |
| OR | †Switch 62.5WG | 11-14 oz | |
| OR | *NY†Intuity 4SC | 6 fl oz | *NY†Intuity is a strobilurin fungicide for control of Botrytis and suppression of powdery mildew. In limited NY and PA trials, *NY†Intuity provided good to fair control of Botrytis equivalent to current standards like Elevate, Vangard, Scala, and †Switch. Do not use on V. labrusca, V. labrusca hybrids or other non-vinifera hybrids. Avoid mixing with organosilicone surfactants. |
| OR | Botector | 6-8 oz | Botector is a preparation of a living yeast-like organism that competes with the Botrytis fungus for colonization sites on the grape flowers and berries. It provides protective activity only and can be killed by some broad-spectrum fungicides used for managing other diseases. |
| OR | ProBlad Verde | 18.1-45.7 fl oz | ProBlad Verde is a fragment of a naturally occurring plant protein that has activity against some fungi. Both products have provided fair to good control in a limited number of NY trials with moderate disease pressure. |
| OR | Howler | 2.5-7.5 lbs | |
Grape berry moth | Treatments in mid-summer targeting offspring from second and subsequent adult flights need to be made to high-risk vineyards. Timing of sprays for offspring from second and third flights is best accomplished using the grape berry moth degree day model available at the Network for Environment and Weather Applications (NEWA): newa.cornell.edu. Low-risk vineyards rarely require this treatment. Sample low- and intermediate-risk vineyards during mid and late season, as well as high-risk vineyards for late season (end of August/early September), to determine if they need to be treated. See New York Food and Life Sciences Bulletin no. 138 for GBM risk assessment protocols or contact the grape IPM program. Most insecticides are incompatible with lime. Check label for incompatibility before tank mixing insecticides with alkaline spray materials. See New York Food and |
| Life Sciences Bulletin No. 118 for information on effects of alkaline hydrolysis on pesticides. Resistance Warning: Grape berry moth resistance to carbaryl (Sevin) and fenpropathrin (Danitol 2.4EC) has been indicated in some vineyards in the Lake Erie Grape Belt. If carbaryl (Sevin) or fenpropathrin (Danitol 2.4EC) or any other insecticide used does not control grape berry moth, do not repeat application with the same material or with the same mode of action. |

European red mite and two-spotted spider mite | An intermittent problem. More likely to be problematic where hot, dry conditions may result in rapidly growing spider mite populations. Fewer than five adult mites/ leaf is unlikely to damage healthy vines, but once this level is reached, vines should be monitored each week to assess the need for treatments. Residues on leaves are generally sufficient to kill them after they hatch (egg stage lasts 2-4 days). If mite densities are very high (average of 30 or more motile mites per leaf), however, it may be necessary to apply back-to-back miticide applications, separated by 5-10 days. If mite predators are abundant, they may greatly reduce the rate of increase of spider mite populations. |
