Abound - A New Fungicide for Grapes
Derived from a new class of chemical compounds extracted from the wood decaying toadstool Strobilurus tenacellus, Abound fungicide, manufactured by Zeneca Ag Products is listed in our grape spray guide for 1998. The fungicide is formulated as a flowable fungicide containing 22.9% of the active ingredient azoxystrobin. Abound is a broad spectrum, preventive fungicide with systemic and curative properties. It can be alternated or tank mixed with other registered fungicides and should be used in a way that minimizes development of fungicide resistance to the chemical.
An integrated pest management (IPM) program for grapes is essential for success with this or any grape fungicide. The IPM program should include practices known to reduce disease development such as a) selection of varieties with disease tolerance or resistance, b) canopy management through pruning and thinning, c) proper timing and placement of irrigation, d) removal of plant debris where inoculum overwinters, and e) use of fungicides only when required.
Abound is useful for management of four different fungal pathogens of grape causing the following diseases: black rot (Guignardia bidwellii), downy mildew (Plasmopara viticola), Phomopsis cane and leaf spot (Phomopsis viticola), and powdery mildew (Uncinula necator). Abound has been tested experimentally in Tennessee and shown to provide downy mildew control equal to that of captan.
The first application of Abound can be made at bud break, and the last one 14 days prior to harvest, but during the season, no more than two sequential applications of the fungicide should be made and no more than six total applications can be made per season. For more details on timing and use of grape fungicides, consult the "Kentucky Commercial Small Fruit and Grape Spray Guide" (ID-94), available at your County Extension Office.
A note of caution: Abound fungicide is very phytotoxic to certain varieties of apples. Do not use the same spray equipment for grapes and apples if Abound is used on grapes. Although the Abound label lists peaches as a legal site for application, we have chosen to omit Abound from our tree fruit spray guides because in Kentucky, it is likely that the same spray equipment would be used for both apples and peaches.

VR = very resistant. No control needed.
MR = moderately resistant. Control only needed with fire blight susceptible rootstocks or under high disease pressure
R = resistant. Control only needed under high disease pressure.
S = susceptible. Control usually needed where disease is prevalent.
HS = highly susceptible. Control always needed where disease is prevalent. These cultivars should receive first priority when control is called for.

Orchard Chemical Suppliers
The following list has been compiled in response to Kentucky grower and County Agricultural Extension Agent requests for outlets from which to purchase many of the pesticides listed in fruit extension publications. In some areas of the state it is very difficult to find pesticides recommended for fruit crops. No supplier endorsement is implied here and a concerted effort was made to locate all of the major fruit chemical suppliers in the state. In addition several suppliers in surrounding states are also listed.
One grower concern was, would the supplier sell and deliver less than case quantities? This is noted in the table. Another question suppliers were asked was who they would sell to.
