Pageant Intrinsic Offers Plant Health Beyond Disease Control

Fungal diseases often rob budding beauties of their vigor and vitality, while environmental stresses, like cold, heat and drought, deplete their marketability. These situations can damage growers’ reputations and decrease potential revenues. Growers can better manage plant quality risks by treating ornamental crops with Pageant Intrinsic brand fungicide.Pageant Intrinsic combines active ingredients boscalid and pyraclostrobin to provide superior broad-spectrum disease control. In addition to excellent disease control, research has shown that pyraclostrobin also provides plant health benefits for agricultural crops and turfgrass. These benefits include enhanced plant tolerance to stress and increased efficiency of plant processes. Pageant Intrinsic is the only fungicide with both disease control and plant health language on its label. Plant Health Benefits — In The Lab And Field For more than five years, BASF worked side-by-side with expert growers to research and develop Pageant Intrinsic applications programs. The resulting plant protection programs help growers to better […]

Cornell’s Margery Daughtrey Is An APS Fellow Recipient

The American Phytopathological Society (APS) has named Cornell’s Margery Daughtrey as an APS Fellow Recipient. The society grants this honor to a current APS member in recognition of distinguished contributions to plant pathology or to The American Phytopathological Society. Daughtrey is nominated for her exceptional contributions to her stakeholders, her professional society and the science and practice of plant pathology. As stated in the citation from the APS, she is considered the most prominent and influential ornamentals pathologist in the United States. Daughtrey is noted for her impressive lecture schedule, publication record and passion for her subject matter. “Several contacted colleagues expressed the view that anyone contemplating a career in outreach would profit more from a week spent observing Margery in the field, and trying to keep up with her, than from any amount of time in a lecture hall,” the citation says. As a diagnostician, Daughtrey was a critical […]

Protect Your Poinsettias From Key Diseases

Pythium. Apply Subdue Maxx at 1 ounce/100 gallons as a soil drench after planting. Rotate with Truban WP (6 to 8 ounces/100 gal.) or Segway (3 ounces/100 gallons) fungicides every four weeks for protection. Botrytis. Be sure to maintain good air movement and low humidity. To avoid botrytis, apply preventative fungicide sprays of Daconil ULTREX alternated with Palladium (4 to 6 ounces/100 gallons), Heritage (4 ounces/100 gallons), Chipco 26019 or Decree (1 lb./100 gallons) after sticking and seven to 10 days later. Powdery Mildew. To prevent outbreaks, maintain good air movement and low humidity in the production area. Apply preventive fungicide treatments throughout the month of October if there is a history of powdery mildew. Effective fungicide spray treatments include Heritage (4 ounces/100 gallons), Palladium (4 to 6 ounces/100 gallons) and several products from FRAC group 3: Eagle 20EW (8 ounces/100 gallons), Terraguard (8 ounces/100 gal.) and Strike 50 WDG […]

BASF Announces New Fungicide For Downy Mildew Of Impatiens And Phytopthora

In September, growers will have another weapon against downy mildew of impatiens when BASF introduces their new fungicide, Orvego. Combining two active ingredients, dimethomorph  (the same one in Stature SC) and a new one, amectotradin, Orvego also provides protection against the whole spectrum of Phytophthora pathogens. BASF announced the new product this week at the OFA Short Course in Columbus, Ohio. “This is a new class of chemical for these diseases,” says Steve Larson, sales manager of ornamentals for BASF. Our other product, Pageant Intrinsic, is a shotgun; it’s broad-spectrum and controls everything. Orvego is a sniper rifle, providing targeted control for specific diseases.”  Downy mildews are host-specific, and while downy mildew of impatiens (Plasmopora obducens) has garnered all the attention recently, other plants can be affected as well. Orvego is active against the whole lineup of downy mildew pathogens. It is labeled for production of ornamentals in greenhouses, lathhouses, […]

Impatiens Downy Mildew Returns

Impatiens Downy Mildew, which began significantly impacting landscape plantings in 2011, is back again in 2012. Or possibly it never actually went away. Cornell’s Margery Daughtery and Ann Chase of Chase Consulting co-presented on recognition and management of Downy and Powdery Mildews Saturday at OFA Short Course, and Daughtery says the situation is already as widespread as last year, if not more so. “We have seen it on Long Island and in New Jersey, Pennsylvania, Ohio, Michigan, Indiana, Illinois, Virginia and other states as well, she says.  While it’s possible some of the disease was transported north from South Florida where there was a significant outbreak at the beginning of 2012, it’s also likely that some incidences are the results of infected plants in the landscape in 2011. There was concern about oospores produced in the stems of plants being carried over from year to year in landscape beds, and […]

Disease Control And Plant Health

Over the last several years many nursery and greenhouse growers have felt increasing financial and environmental pressure to make sustainability-driven improvements to reduce inputs —including water, chemicals and fuel — but reductions must not sacrifice plant quality. Fulfilling sustainable needs and business demands is challenging, but not impossible. Like growers, BASF views sustainability as achieving more using fewer inputs, while ensuring profitability, caring for the environment, and meeting the needs of society and future generations, in short, doing more with less. BASF research and development continually brings new innovations to market that help growers be more successful. Recent examples of this research and development include its pyraclostrobin-based product Pageant® Intrinsic™ brand fungicide. Pageant Intrinsic is the first fungicide in the ornamental market labeled for disease control and plant health. It gives growers industry-leading, broad-spectrum disease control and the bonus of plant health activity — without additional inputs. In addition to […]

Timing Fungicides And PGRs To Control Greenhouse Pests

The management of pests and diseases during the production of greenhouse crops is not an isolated event. As such, interactions may occur that can have a significant impact on the success of any pest management strategy. For example, under conditions of high relative humidity (greater than 75 percent), naturally-occurring populations of beneficial or insect-killing fungi may cause substantial mortality of insect and mite pests. Although beneficial fungi typically require high relative humidity, these fungi can be effective when the microclimate relative humidity around the spore (e.g., leaf surface) is high. This can occur even when the relative humidity within a greenhouse is less than 50 percent. In addition, the effectiveness of beneficial fungi can vary depending on light intensity, plant size and plant architecture. Fungicides used to manage plant diseases may create issues associated with the compatibility of these chemicals and beneficial fungi, such as Beauveria bassiana, Metarhizium anisopliae and […]
