Agrochemical.net Chinese website:UPL recently announced that its fungicide KASUMIN®
has been granted an emergency exemption from Section 18 of the U.S. Environmental Protection Agency (EPA) and California Department of Pesticide Regulations (CDPR). It can be used in almond wood in 2021 to control pseudomonas syringae Bacillus (scientific name:Pseudomo
nas syringae; common name:bacterial blast). The approval applies to nearly 100,000 acres of almond wood in California, but is limited to butte, Colusa, Fresno, Glenn, Madera, Merced, San Joaquin, Stanislaus, Sutter, Tehama, Yolo and Yuba counties. This is the second consecutive year that KASUMIN Fungicide has been exempted from Section 18.
UPL Specialty Crops Marketing Manager David Davies said:“The approval of the fungicide KASUMIN in Section 18 will provide much-needed support to California almond growers to help them control Pseudomonas syringae in the coming season. KASUMIN approved Different target action sites protect the health of fruit trees, crop quality and yield, and are effective tools for the prevention and control of this bacterial disease.”
According to Section 18, KASUMIN can be applied twice at 64 fluid ounces per acre. It should be applied during the period from the blooming of the flower buds to the falling of the petals, which is conducive to the development of the disease. It is forbidden to use it after the petals fall off.
After obtaining federal and state registration in 2019, KASUMIN has been successfully applied to the control of walnut wilt in California walnut planting. KASUMIN is the only member of FRAC Group 24 and has high preventive activity against many plant pathogens. Its active ingredient kasugamycin (kasugamycin) has a unique active site and mode of action.
The fungicide mainly plays a preventive role. It is suitable for application during early budding and flowering to form a protective layer of fungicide on new green tissues and flowers. KASUMIN is a local systemic bactericide. In addition to controlling plant diseases through contact, the active ingredients in KASUMIN can also be absorbed by the green tissues of plants, thereby controlling target pathogens more widely.
KASUMIN has no cross-resistance to other fungicides, and it is most effective when used in a rotation program. After KASUMIN is administered to alba, the restricted entry interval (REI) is 12 hours, and the safe interval (PHI) is 100 days. The product has no animal or human use.
