SITUATION

Use of methyl bromide is being phased out.

Telone C35 is a viable replacement for MBr

Control of nutsedge often variable with Telone C35

Sandea evaluated for post-emergence nutsedge control in tomato

production

Summary

Phytotoxic response to post applications of Sandea was not observed across seasons, growth stages, or cultivars.

Tomato yield or fruit size was not significantly affected by post applications of Sandea

Tomato plants have excellent tolerance to post applications of Sandea at both the 0.5 and 1.0 oz./A rates
