Masters Theses & Specialist Projects

Johnsongrass is one of the more limiting factors in soybean production and is the most serious weed problem in the Southeastern United States. Actually, different herbicides are used in johnsongrass control, and still there are new herbicides which are being tested. Two experimental herbicides for johnsongrass control in soybeans are BAS 9052 and S-734.

The experiments were conducted in 1980 and 1981 with the objective to evaluate the effectiveness of S-734 alone and in combination with mefluidide and BAS 9052, BAS 9052 applied early or late postemergence, trifluralin, alachlor, and fluchloralin for seedling and rhizome johnsongrass control.

In both areas …


Evaluation Of Herbicides For Suppression Of Rhizome Growth From Johnsongrass (Sorghum Halepense L.) In Corn And Soybeans, John Oakes Jan 1977

Evaluation Of Herbicides For Suppression Of Rhizome Growth From Johnsongrass (Sorghum Halepense L.) In Corn And Soybeans, John Oakes

Masters Theses & Specialist Projects

Johnsongrass (Sorghum halepense L.) presents a serious problem in the production of corn and soybeans in Kentucky.

Various rates of the thiocarbamates, dinitroanilines, carbamates, amides, ureas, and triazines were used in association with the crops corn (Zea mays L.) and soybeans (Glycine max L.) to determine the degree of suppression on rhizomatous johnsongrass infesting the previously named crops.

Suppression was determined by selecting areas within each treated plot, counting the number of culms, then harvesting johnsongrass rhizomes. Dry weights of rhizomes were then determined as a measure of rhizome suppression.

Results show that of …
