The formulation of KWH02 was tested according
to China GB15670-1995 (test method on toxicity for
pesticide registration). The report of the toxicological
studies conducted by Jiangsu Provincial Sanitary and
Anti-Epidemic Station revealed that the oral LD50 of
the male and female rats were higher than 5000 mg/kg
body weight. Such a result makes clear that this
compound belongs to the category of low toxicity
herbicides, while the acute dermal irritation test and
the integral index of the acute eye irritation test on
rabbit showed no negative effects at all.
