Pesticides Update: March 2021

According to California Ag Today, the US Environmental Protection Agency (EPA) and California Department of Pesticide Regulation recently accepted a Section 18 petition to allow the use of Kasumin 2L (kasugamycin) to control bacterial blast (Pseudomonas sp) in almonds in 12 counties in the State of California.
 
The registration allows up to two applications under anticipated cold or freezing conditions at a use rate of 64 fl. oz. per acre from February 12, 2021 through petal fall. Application after petal fall is prohibited. Kasugamycin may only be used during bloom.
 
The approval applies to the counties of Butte, Colusa, Fresno, Glenn, Madera, Merced, San Joaquin, Stanislaus, Sutter, Tehama, Yolo and Yuba.

As reported by AUSVEG, following consultation with the Australian Pesticides and Veterinary Medicines Authority (APVMA), ADAMA Australia has voluntarily canceled its registration for Methidathion (Suprathion 400 EC Insecticide).
 
Since February 4, 2021, the use of Suprathion in Macadamia plantations is not permitted under any legislation.
