The product is based on a new strain of Bacillus amyloliquefaciens discovered by MBI, targeted to downy mildews, white molds, Botrytis gray mold and bunch rot. The fungicide also controls pathogenic soil fungi, including diseases such as Fusarium and Rhizoctonia, as shown in field trials in the
Growers have few choices of products that perform well on the group of fungi that cause downy mildews on grapes, potatoes, leafy greens and other crops, as well as white molds on leafy greens, succulent and dry beans. Adding to the challenge, these crop disease-causing plant pathogens have also developed resistance to major chemistry classes of conventional pesticides. Stargus™ is the result of MBI's directed screening discovery program to find a solution that addresses such a specific market need. This product is also complementary and additive to the broad spectrum of diseases covered by MBI's first biofungicide, Regalia®, providing a solid one-two punch to a broad spectrum of plant pathogens. MBI and partners also are testing this Bacillus-based product for seed treatment applications.
"We knew that new solutions for downy mildews were badly needed, so our team of scientists set out to find one,"
Tests conducted at MBI's research and development lab show that Stargus™ works by colonizing plant root hairs, leaves and other plant surfaces thereby preventing establishment of fungal and bacterial pathogens, including Fusarium, Sclerotinia, Botrytis, Rhizoctonia, and Sclerotium. Additional R&D indicates that the bacterium also produces natural compounds, some of which inhibit bacterial and fungal mycelial growth, as well as spore germination. In addition, the bacteria trigger systemic acquired resistance and induced systemic responses in the plant, creating a healthier and stronger plant to ward off diseases and increase growth and yield. MBI has been issued a patent on the novel strain used in Stargus™.
Field studies showed efficacy against downy mildew, Botrytis bunch rot and black rot on grapes, downy mildew on cucurbits, pink rot, white mold and late blight on potatoes, Cercospora leaf spot on sugar beets, Fusarium of tomato and celery, and white mold on soybean, sunflower, beans, lettuce and canola, and soil applications on potatoes for control of Rhizoctonia and Phytophthora eurythroseptica (pink rot). MBI also is testing for seed treatment applications and is investigating
applications for turf and ornamental markets. Successful field trials have been conducted in
