A bioassay test was conducted to evaluate the sensitivity of pepper to simulated imazamox
residues in loam soil with three different levels of moisture (20, 50 and 70% field water capacity
– FWC). The soil concentrations of imazamox were established at: 6.25, 12.5, 25, 50, 100, 200,
400 and 800 μg a.i./kg soil. The parameters measured 21 days after treatment were shoots
and roots fresh weight and root length as well as the content of water soluble proteins.
Imazamox caused a growth delay and lower protein content at all levels of soil moisture, and
the degree of change depended on the application rate. In plants grown in soil with 20%
FWC, root fresh weight showed the highest inhibition, root length showed less sensitivity
and there was no statistically significant reduction in shoot fresh weight. In soil containing
50% FWC, only the two highest concentrations caused a significant reduction in shoot fresh
weight, while root lenght and root fresh weight were inhibited by ≥50 a...nd ≥100 μg a.i./
kg soil, respectively. Root fresh weight was the most sensitive parameter in the soil of 70%
FWC, while shoot fresh weight was the least sensitive parameter. Soluble protein contents
were lower in all trial variants, but the changes did not depend on herbicide concentration.
