5.2.9 FIRST POSTBLOOM SPRAY (10-14 days after immediate prebloom)

Phomopsis cane and leaf spot (rachis and fruit infections)

Fruit infections can occur from bloom through pea-sized berries then remain dormant until late summer or early fall, when they reactivate and rot the berries. In hedged or other high-risk vineyards (those with a history of the disease, with poor air movement near woods, etc.), significant pre-harvest fruit rot can develop on highly susceptible cultivars, such as Niagara, if the bloom and early postbloom period is wet and fungicidal protection is absent. Rachises also remain susceptible during this period.

Powdery mildew

THIS IS THE MOST CRITICAL TIME OF THE YEAR FOR CONTROL OF CLUSTER INFECTIONS. Spray programs should be "tightened," especially on highly susceptible varieties (see Table 3.2.2) and/or if cloudy warm days and nights prevail during this period. Pay particular attention to choice of fungicides, rate, spray interval, and coverage.

Resistance Warning: Widespread "partial" resistance to the sterol inhibitor or DMI (Group 3) fungicides (generic tebuconazole products, tetraconazole [Mettle], myclobutanil [Rally], difenoconazole products [Group 3 component of Revus Top, Inspire Super, Quadris Top, *^NYAprovia Top], flutriafol products [†Rhyme, †Topguard EQ], triflumizole products [*^NYViticure, *^NYProcure, *^NYTrionic], and mefentrifluconazole [*^NYCevya]) has limited their usefulness during this critical period. Thus, most are not recommended on V. vinifera or highly susceptible hybrid cultivars from the immediate prebloom through early postbloom stage of development. However, *^NYCevya and Revus Top have provided very good to excellent control even on such cultivars in several repeated trials where other DMI fungicides sometimes did not (as have Inspire Super, Quadris Top, and *^NYAprovia Top when applied at their top label rates, which provide a dose of difenoconazole equivalent to Revus Top). Nevertheless, some premium powdery mildew products have sometimes given better control than even this best of the Group 3 fungicides. It is strongly recommended that growers make no more than three applications of all Group 3 products combined in any one season, in order to minimize further loss of sensitivity to them. CAUTION: DO NOT USE REVUS TOP, QUADRIS TOP, INSPIRE SUPER, OR *^NYAPROVIA TOP ON CONCORD GRAPES (CAUSES INJURY). CHECK INDIVIDUAL LABELS FOR OTHER CULTIVARS THAT MIGHT ALSO BE AFFECTED. *NY Cevya should not be applied/tank mixed with horticultural oils (JMS Stylet oil, Purespray green), or injury to foliage and fruit may occur.

Quadris Top is a product that combines azoxystrobin (the active ingredient in Abound) and difenoconazole, the Group 3 component in Revus Top and Inspire Super. Note, that at the lowest label rate of 12 fl oz/A, Quadris Top provides 87% the dose of difenoconazole provided by the label rate (7 fl oz/A) of Revus Top and a dose of azoxystrobin equivalent to the lowest label rate of Abound. At 14 fl oz/A, Quadris Top provides a difenoconazole dose equivalent to that provided by the label rate of Revus Top. †Topguard EQ similarly combines azoxystrobin and a different Group 3 fungicide (flutriafol), the active ingredient in †Rhyme. However, at rates labeled for powdery mildew control, it providessignificantly lower doses of azoxystrobin and a less effective Group 3 fungicide than does Quadris Top.

CAUTION: DO NOT USE PRISTINE, QUADRIS TOP, *^NYAprovia top, OR FLINT EXTRA ON CONCORD GRAPES OR PRISTINE ON NOIRET GRAPES (CAUSES INJURY). CHECK INDIVIDUAL LABELS FOR OTHER CULTIVARS THAT MIGHT ALSO BE AFFECTED.

Note that Quadris Top, Abound, †TOPGUARD EQ, and *^NYdexter max are extremely phytotoxic to certain apple varieties due to the active ingredient azoxystrobin. See the ABOUND entry within Section 3.2 for information concerning use of these fungicides in Pennsylvania.

The newest label allows a maximum of two applications per year at the 3.4 fl oz rate or one application per year at the 6.8 fl oz rate.

OR

*^NY†Luna Experience

6.0-8.6 fl oz

*^NY†Luna Experience combines fluopyram, a "Group 7" fungicide similar to boscalid (the non-strobie component of Pristine) with tebuconazole, a traditional DMI (Group 3) fungicide. It has provided excellent activity against powdery mildew in multiple trials. The 6.0-fl oz rate is adequate for powdery mildew and for Botrytis during the bloom and post-bloom period, but the 8.6 fl oz/A is likely to be necessary for reliable black rot control unless another product active against this disease (e.g., mancozeb) is being used as well.

OR

*^NY†Luna Sensation

7 fl oz

*^NY†Luna Sensation is another newer product with the same fluopyram active ingredient, but combined with

trifloxystrobin, a traditional strobilurin (Group 11) fungicide, instead of the tebuconazole found in *^NY†Luna Experience. The 7.0 fl oz label rate delivers a rate of fluopyram about equal to 8.6 fl oz on the *^NY†Luna Experience label. That same 7.0 fl oz rate also delivers about the same amount of trifloxystrobin as 3.5 fl oz of Flint Extra, adequate for good to excellent black rot control. CAUTION: Do not apply this product to Concord grapes or injury may occur.

OR

*^NYAprovia 0.83EC

8.6-10.5 fl oz

*^NYAprovia is a Group 7 fungicide; it is a solo product (not combined with another active ingredient). *^NYAprovia has provided excellent activity against powdery mildew in multiple trials, but has not provided reliable activity against any other disease.

OR

*^NYAprovia Top 1.6EC

8.5-13.3 fl oz

*^NYAprovia Top is a relatively new product that combines the active ingredient contained in *^NYAprovia plus an effective rate of the DMI fungicide difenoconazole: both active ingredients have considerable activity against powdery mildew.

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. Regalia should only be considered for powdery mildew control during post bloom in an organic spray program. It should not be relied on for conventional powdery mildew control during this critical window.

OR

ProBlad Verde

18.1-45.7 fl oz

ProBlad Verde is a biopesticide that has provided fair to good control of powdery mildew in NY and PA trials. ProBlad Verde is OMRI listed and should only be considered for powdery mildew control during post bloom in an organic spray program. ProBlad Verde should not be relied on for conventional powdery mildew control during this critical window. No more than 5 applications can be made during the season, and ProBlad Verde may be applied no more than twice before alternating with a product that has a different mode of action.

Ridomil Gold Copper

2 lb

Resistance Warning: Resistance to Ridomil by the downy mildew organism develops easily and is widespread in countries where this fungicide has been used regularly. To reduce the risk of developing resistance, use no more than one to two total applications of Ridomil per season (MZ and Copper formulations combined), do not apply two applications in a row, and do not attempt "rescue" treatments with this material if an epidemic is in progress.

The 2.5 lb rate of Ridomil Gold MZ provides the same amount of mancozeb as 2.0 lb of the 75 DF and 80WP formulations of Dithane, *^NYManzate, or Penncozeb.

OR

Ridomil Gold MZ WG

2.5 lb

Thus, if protection is needed against black rot, Phomopsis, angular leaf scorch, or anthracnose, tank mix with an additional 1-2 lb/A of these mancozeb products (or with an equivalent amount of a flowable mancozeb formulation), or with the full rate of an alternative material. The 2-lb rate of Ridomil Gold Copper contains 1.2 lb of copper hydroxide. Hence, follow the usual precautions pertaining to the use of coppers. Do not apply Ridomil Gold MZ within 66 days of harvest; Ridomil Gold Copper may be applied up to 42 days before harvest.

Abound 2SC

Quadris Top 2.7SC

†Topguard EQ 4.3SC

*^NYSovran 50WG

Pristine*^NY†Reason 500SC

not recommended for use alone

Resistance Warning: Downy mildew resistance to the "Group 11" fungicides (Abound, Flint Extra, Pristine, Quadris Top, *^NY†Reason, *^NYSovran, †Topguard EQ) has developed in multiple NY vineyards, causing significant crop loss. Thus, it is now risky to rely on these fungicides for control of downy mildew, particularly in the prebloom through early postbloom period while fruit are highly susceptible. When such resistance occurs, none of these fungicides will provide commercial control of the disease, and they must be combined with an effective rate of an unrelated fungicide to avoid potential crop loss. If using these materials, it is recommended that they be applied a maximum of two times per year for all Group 11 products combined. Note that neither the boscalid component of Pristine, the difenoconazole component of Quadris Top, nor the flutriafol component of †Topguard EQ provide control of downy mildew and so will not help to manage strobilurin-resistant populations. CAUTION: Do not use Quadris Top on Concord grapes (causes injury). Note that Quadris Top, Abound, †topguard eq, and *^NYdexter max are extremely phytotoxic to certain apple varieties due to the active ingredient azoxystrobin. See Section 3.2 for information concerning ABOUND and QUADRIS TOP and the use of these fungicides in Pennsylvania.

*^NYSovran has significant activity against non-resistant downy mildew, but it is not as effective as Pristine or the azoxystrobin products. Therefore, *^NYSovran is not recommended on highly susceptible varieties even where resistance to the Group 11 fungicides is not yet a problem; if using *^NYSovran on such varieties, tank mix with a protectant fungicide active against downy mildew.

OR

ProPhyt

2-4 pt

ProPhyt and Phostrol are among several products containing phosphorous acid (phosphonate, phosphite) that are registered for control of downy mildew. Phosphonate products provide limited protective and good to very good postinfection activity. The labeled rate ranges given are intended to account for variable canopy densities and disease pressure: The lower rates are appropriate during the prebloom period, but they should be increased as canopy volumes increase rapidly after fruit set and/or when significant post-infection activity is required. Prophyt and Phostrol contain comparable levels of active ingredient and Rampart contains about 7% less;

OR

Phostrol

2.5-5 pt

OR

Rampart

2-6 pt

all appear to provide comparable levels of control when used at the same rate of product. Optimum spray intervals depend on weather conditions and rate applied; 10 days appears to be effective, whereas 14 days is too long under heavy disease pressure. Refer to the discussion on "phosphorous acid" in the "Fungicides" section.

OR

Revus 2SC

8 fl oz

Revus controls only downy mildew. Revus Top is a combination product that contains the active ingredient from Revus plus a second fungicide (difenoconazole, a DMI or Group 3 material) that controls powdery mildew, black rot, and anthracnose. The Revus products have proven to be very effective under high disease pressure. Both are absorbed by plant tissues, so are not subject to wash-off once this has occurred, and they provide both post-infection and protective activities (The post-infection activity of the Revus products is likely to be maximized by applying them with a penetrating surfactant). Revus is labeled for use at 7-day intervals but has given very good to excellent control when applied on V. vinifera cultivars at14-day intervals in several NY trials; it has a 14-day PHI. Revus Top is labeled for use at 14-day intervals, and also has a 14-day PHI.

CAUTION: DO NOT USE PRISTINE, QUADRIS TOP, OR REVUS TOP ON CONCORD GRAPES (CAUSES INJURY). CHECK INDIVIDUAL LABELS FOR OTHER CULTIVARS THAT MIGHT ALSO BE AFFECTED.

*^NYGavel is a relatively new fungicide labeled for control of downy mildew and other diseases. It is a combination of two active ingredients: (i) zoxamide, a downy mildew-specific fungicide; and (ii) mancozeb. When applied at the labeled rate of 2.0-2.5 lb/A, it provides the same amount of mancozeb as 1.8-2.2 lb of standard 75DF formulations of other mancozeb products such as Dithane, Penncozeb, etc. Thus, for control of labeled diseases other than downy mildew, *^NYGavel should be tank-mixed with sufficient quantities of another mancozeb product to provide a mancozeb dosage equivalent to the labeled rates of 3-4 lb/A of the 75DF formulations of such products. In a limited number of trials, *^NYGavel has provided fair to good control of downy mildew when applied at 14-day intervals.

OR

Ranman 400SC

2.1-2.75 fl oz

Ranman is a new fungicide unrelated to any other registered product. It is active only against downy mildew, primarily as a protectant but with limited post-infection activity.

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) acetoctradin, 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 good to excellent control when used at 14-day intervals on V. vinifera cultivars 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

Anthracnose

Only a common problem on a few specific varieties, particularly Marquette and Reliance and, to a lesser extent, Vidal Blanc (see the entry under Anthracnose in Section 3.1, Vineyard Disease Management, for a list of other susceptible varieties and the weather conditions favoring its development). Only Rally, Inspire Super, Revus Top, Mettle, Quadris Top, and Pristine are specifically labeled for control of anthracnose, although traditional broad-spectrum fungicides also have activity against it. Experience with controlling anthracnose in NY and neighboring states suggests that sprays of mancozeb, ziram, or captan applied to control other diseases are likely to provide control of anthracnose as well.

Grape berry moth

Classify vineyards as low, intermediate, or high risk of grape berry moth attack, using established protocols. See New York Food and Life Sciences Bulletin No. 138 for GBM risk assessment protocols, or contact the Grape IPM program. High- and intermediate-risk vineyards (i.e. high value wine grapes or vineyards with a history of GBM problems) receive insecticide treatment at this time. Low-risk vineyards do not need to be treated at this time. Use a spreader-sticker (at corresponding label rates) when recommended. This spray is timed to coincide 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. Note that *^NY†Intrepid is more effective when applied at start of egg-laying. Timing of sprays is best accomplished using the grape berry moth degree day model available at the Network for Environment and Weather Applications (NEWA): newa.cornell.edu.

A minimum of 50 gallons of water per acre, every row, should be used at this time. 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. Regardless of control, it is recommended that insecticides with different modes of action be used during the season. If control of grape berry moth is a problem, then reexamine your management practices (e.g. choice of insecticides, spray timings, spray coverage, etc.).
