- Intervention effect Atrazine at 1.0 kg a.i./ ha controlled small black pigweed.
- Intervention effect Atrazine at 1.0 kg a.i./ ha controlled small sesbania pea.
- Intervention effect Atrazine at 2.25 kg/ha controlled larger black pigweed.
- Intervention effect Atrazine at 2.25 kg/ha controlled larger sesbania pea.
- Intervention effect Picloram plus 2,4-D controlled larger sesbania pea.
- Intervention effect Fluroxypyr controlled larger sesbania pea.
- Intervention effect Atrazine mixtures controlled larger sesbania pea.
- Intervention effect Atrazine mixtures at 1.0 kg/ha controlled both weeds as effectively as atrazine alone at 2.25 kg/ha.
- Intervention effect Several herbicide treatments caused sorghum injury symptoms.
- Intervention effect These herbicide treatments delayed sorghum flowering.
- Intervention effect These herbicide treatments sometimes reduced sorghum grain yield.
- Observation Sorghum susceptibility to the herbicides varied with seasons and cultivars.
- Intervention effect Yield reductions were smaller with lower rate herbicides in atrazine mixtures than alone.
- Intervention effect All sorghum cultivars tolerated atrazine at 4.5 kg/ha.
- Recommendation The authors recommend spraying black pigweed under 10 cm with atrazine at 1.0 kg/ha.
