Title

Control of Volunteer Corn and Giant Foxtail in Soybeans

Robert N. Andersen Weed Science 1976. doi:10.1017/s0043174500065905

Other claims from this paper (9)

Intervention effect Soybeans tolerated the highest herbicide rate of 3.36 kg/ha.
Intervention effect HOE 22870 was more effective than HOE 23408 on giant foxtail in soybean.
Intervention effect HOE 22870 was less effective than HOE 23408 on corn in soybean.
Observation The optimum time of herbicide application in soybean was the first trifoliolate stage.
Observation Several corn inbred lines had considerable tolerance to HOE 23408 in a greenhouse study.
Observation The most susceptible corn inbred reached 100% control with HOE 23408 at 0.56 kg/ha in the field.
Observation The most resistant corn inbred reached 22% control with HOE 23408 at 0.56 kg/ha in the field.
Observation HOE 23408 at 1.12 kg/ha gave control of corn ranging from 100% to 42% across inbreds.
Intervention effect Both herbicides performed quite similarly in soybean.

Other claims from this paper (9)

Intervention effect The same planting method increased alfalfa yield by 9%.
Intervention effect The simultaneous planting method reduced corn silage production by 20 to nearly 50%.
