In the original publication of this article, quantities of dried Indian mustard tissues in the petri dish germination tests were reported in mg cm–2. The calculations were based on a 10 cm diameter petri dish.
However, the petri dishes had precisely 9.11 cm in diameter. Consequently, the values of all further references to rates in mg cm–2, quantities of ITCs reported by cm–2, to the b coefficient parameter of the nonlinear response (Table 2), to the coefficient and intercept of the linear regression analyses (Table 5) in regard to EC50 and LD50 should be multiplied by a factor of 1.205. This does not alter the analyses nor conclusions.
The authors apologize for the error.
