e0“Field research was conducted at Rosemount, MN in 1990 and 1991 to determine the effect of starch encapsulation on weed control in corn with alachlor, metolachlor, and atrazine under two weed densities”
e1“At low weed densities (122 total plants/m 2 ), giant foxtail and Pennsylvania smartweed control were not different with full rates of herbicide applied in starch encapsulated or commercial formulations”

Other claims from this paper (8)
- Intervention effect Velvetleaf control was lower with starch-encapsulated than with commercial herbicide formulations, regardless of velvetleaf density.
- Intervention effect At high giant foxtail densities, control was not affected by formulation with full rates of alachlor plus atrazine.
- Intervention effect At 75% rates of alachlor plus atrazine, giant foxtail control was lower with starch-encapsulated than with commercial formulations.
- Intervention effect At 75 and 100% rates of metolachlor plus atrazine, giant foxtail control was lower with starch-encapsulated than with commercial formulations.
- Intervention effect At low weed densities, corn yield did not differ from the weed-free control with any treatment.
- Intervention effect At low weed densities, corn yield with starch-encapsulated metolachlor plus atrazine at 75% rates differed from the weed-free control.
- Intervention effect Alachlor plus atrazine at full rates was the only starch-encapsulated treatment whose corn yield did not differ from the weed-free control at high weed densities.
- Intervention effect All commercial formulation treatments gave corn yields not different from the weed-free control at high weed densities.
