BASF Corp. gave pest control advisers a glimpse of the new products it plans to introduce in coming years at a recent field day at its Dinuba, Calif., research station.
During the next few years, company officials say they hope to have federal and state registrations for Merivon and Priaxor fungicides, Zampro fungicide and Nealta miticide.
The Research Triangle Park, N.C.-based company recently received federal and California registration for Treevix herbicide and Vivando fungicide.
• Treevix, a pre-emerge herbicide, is based on the Kixor technology, a brand name for the active ingredient saflufenacil.
It is labeled for broadleaf weed control in bearing and non-bearing citrus, pome fruit and tree nuts, according to the label.
It can be tankmixed with most of the contact herbicides, such as glyphosate, glufosinate and paraquat.
• Vivando fungicide received federal and California registrations in December 2010.
The fungicide contains the active ingredient metrafenone, which belongs to the Fungicide Resistance Action Committee's Group U8.
It controls powdery mildew in grapes.
In trials conducted on chardonnay and carignan grapes—varieties very susceptible to powdery mildew—Vivando was one of the top performers, says Max Landes, research station manager.
The cool spring, coupled with unusual rains, created heavy powdery mildew pressure and really put fungicides to the test, he says.
• On the horizon and not yet registered are two fungicide premixes that include Xemium, the brand name for the active ingredient fluxapyroxad.
Xemium is belongs to the Fungicide Resistance Action Committee's Group 7. That is the same group to which boscalid, or Endura, belongs.
Xemium will be paired with the strobilurin pyroclastrobin, the same active ingredient in Headline and Cabrio. Strobilurins belong to the FRAC Group 11.
In permanent crops, the premix will be marketed as Merivon and contain a 1:1 ratio of Xemium to pyroclastrobin.
In row crops, it will be marketed as Priaxor and contain a 1:2 ratio of Xemium to pyroclastrobin.
It is active on powdery mildew on grapes, tomatoes and cucurbits; and brown rot in stone fruit, among other diseases.
Although both Xemium and boscalid belong to the same FRAC class, Xemium is more mobile and provides a broader spectrum of disease control, Landes says.
BASF officials are still mulling how to position Pristine, a premix of boscalid and pyroclastrobin, once the Xemium-based premixes are registered, says Steve Broscious, BASF technical market manager.
• Also in the pipeline is Zampro, a new fungicide premix that is effective against oomycetes, including downy mildew, late blight, phytophthora and crown rots. It has no activity on pythium.
It is not yet registered.
Zampro is a premix of ametroctradin, a new active ingredient, and dimethomorp, the active ingredient in Forum fungicide.
• Nealta is a new miticide that contains cyflometofen, the only member of the Insecticide Resistance Action Committee's Group 25.
It is not yet registered.
It has a unique mode of action and is effective on a host of mites, including spider, citrus red, Pacific, Williamette, European red and two-spotted.
Nealta has activity on all of the life stages, from egg to adult, and provides up to 28-day residual activity.
David Haviland, a University of California Cooperative Extension farm adviser in Kern County, has the product in his field trials this year.
