Other claims from this paper (16)
- Intervention effect The clomazone sequence controlled 86% of common lambsquarters in 1996.
- Observation Other herbicide treatments controlled at least 94% of weeds.
- Observation Greatest soybean yields occurred with EPOST glyphosate in 1996.
- Observation Greatest soybean yields occurred with LPOST glyphosate in 1997.
- Observation Preplant residual herbicides benefited the late POST application only in 1996.
- Observation Soybean injury remained at or below 5% except with glyphosate and imazethapyr in 1997.
- Intervention effect Imazethapyr alone controlled velvetleaf by 99% in 1997.
- Intervention effect Imazethapyr alone controlled giant foxtail by 92% in 1997.
- Observation Yields with glyphosate alone were similar across rates and timings except one comparison.
- Intervention effect The 630 g/ha LPOST glyphosate treatment yielded less than 420 g/ha LPOST.
- Intervention effect SAN 582 with glyphosate gave yields equivalent to the highest-yielding treatments.
- Intervention effect Cloransulam added to EPOST glyphosate lowered soybean yield.
- Intervention effect Chlorimuron plus thifensulfuron added to LPOST glyphosate lowered soybean yield.
- Intervention effect Imazethapyr added to LPOST glyphosate lowered soybean yield.
- Observation No herbicide combination performed better than timely glyphosate alone.
- Recommendation A preplant residual herbicide may help when early weed competition is severe and timely glyphosate is impossible.
