Testbiotech comment on EFSA opinion regarding insect‐resistant and herbicide‐tolerant soybean DAS-81419-2 × DAS-44406-6

TESTBIOTECH Background 20 - 12 -2020

Stacked soybean DAS-81419-2 x DAS-44406-6 contains genes conferring resistance to three
groups of herbicides:

– glyphosate (2mEPSPS protein),
– 2,4-dichlorophenoxyacetic acid (2,4-D) and other related phenoxy herbicides (AAD–12
– glufosinate ammonium (PAT protein).

Further, the plants have resistance to lepidopteran pests through the expression of Bt toxins, Cry1F
and Cry1Ac. Implementing Regulation 503/2003 was applied in this case. In its opinion, EFSA “does not identify any safety issues pertaining to the intended uses of soybean DAS-81419-2 x DAS-44406-6” (EFSA,

However, according to Testbiotech, the data presented are insufficient to demonstrate safety.
