Rice injury
ANOVA indicated a herbicide treatment by year interaction for
rice injury data collected at 7 and 14 days after saflufenacil applications
(DAA) (data not shown). Therefore, results were presented
for each year separately. Saflufenacil injury symptoms are characterized
by chlorosis of the leaves followed by necrosis of the
affected tissues. Overall, visual injury increased as saflufenacil dose
increased from 12.5 to 50 g ha1 in both years (Table 1). In the year
2009, evaluations conducted at 7 DAA demonstrated injury as high
as 53% when the highest dose of saflufenacil was applied EPOST.
Statistically similar injury (38%) was observed when the same dose
was applied LPOST. Treatments containing the lowest dose of
saflufenacil applied EPOST and LPOST displayed injury lower than
10%.
