Chlorothalonil is a broad-spectrum, protectant fungicide that has been the generally accepted control of choice for target spot for a number of years (JONES & JONES 1984). For the most part, chlorothalonil also performed well in our tests. However, several newer compounds provided outstanding control of target spot. Azoxystrobin, one of the strobilurin fungicides with a chemistry based on a natural product from a mushroom, provided excellent control of target spot in Spring 2001 and was nearly as effective in Spring 2002. This compound is now labeled for use on tomatoes in the United States and fits well into an integrated pest management (IPM) program. It has low mammalian toxicity and is environmentally safe.Azoxystrobin was used in rotation with chlorothalonil in our tests because of the manufacturer’s legitimate concerns for rapid development of fungicide resistance. The limited mode of action of azoxystrobin makes it vulnerable to development of resistance among target fungus populations.The current label for azoxystrobin reads that the farmer is not to make more than two sequential applications of this compound and to alternate applications with broad-spectrum fungicides. We followed this advice in our tests and tank-mixed or alternated azoxystrobin with broad-spectrum materials such as chlorothalonil. Pyraclostrobin,another strobilurin fungicide, tested in Spring 2002, has very recently received full registration for use on tomatoes in the United States and gives growers another option for rotation in an integrated program for target spot control.
