BASF Corp's much anticipated worldwide introduction of a fungicide, F 500, e on more than 100 crops will include federal and California state registrations this December, according to Jerry Minore, BASF manager of market strategy for fungicides.

Minore spoke at a field tour recently at BASF's Dinuba, Calif., research farm where new brand name products containing the active ingredient F 500 were reviewed by marketing and research personnel.

Minore said BASF has been working parallel registrations at both the state and federal levels for Cabrio and its cousin Headline.

Expected uses

When the label is approved, the F 500 brand Cabrio EG will be registered in California this December, according to Minore, to control eight diseases of cucurbits; seven diseases of tomatoes; three cherry diseases; two in onions; three in carrots and two in pistachios. Headline will be for use on citrus, grasses grown for seed, peanuts, potatoes, sugarbeets, wheat and other row and field crops.

Powdery mildew is the one disease most often listed that Cabrio controls, but this new compound will not be registered on grapes or stonefruit in California. One reason is that BASF also markets Sovran for powdery mildew control.

However, company spokesmen said the primary reason Cabrio EG will not be registered for grapes, stone fruit and almonds is that another compound, BAS 516, is expected to be registered for grapes and the other crops in 2003. It contains F 500, a strobilurin, and a “mystery compound” for control of not only powdery mildew on grapes, but downy mildew, phomopsis, the San Joaquin Valley bunch rot complex and boytrtis bunch rot as well.

Alan Kennedy, new BASF regional manager, said the 516 compound is a reduced risk compound that also will be registered for against anthracnose, blossom blight, shot hole and scab. It also will be labeled for as a post harvest fungicide for stored fruit. BASF expects California registration for this compound in 2003.

But for 2002, the emphasis will be one the F500 product, which Minore said will provide “economical broad-spectrum control that maximizes yields while producing high quality” crops.

F 500 has been shown to be active on four classes of fungi. It will control 49 diseases, more than any other fungicide on the market, according to Minore.

As with most new fungicides registered in recent years, BASF is recommending growers apply it only four times per season as part of a resistance management strategy.
