Abstract: The present invention relates to bacteria which can be used as biological control agents for soybean diseases such as those caused by the fungus Rhizoctonia solani. These biological control agents are specific strains of Bacillus megaterium and can also be used for enhancement of soybean plant growth and yield, as well as for the production of antibiotics directed toward crop fungal diseases.

Abstract: An improved saw bar and a chain sawing assembly includes a frame which houses a drive engine or motor and receives the saw bar, an endless cutting chain, and a sprocket mechanically coupling the drive engine to the cutting chain. The saw bar includes a bar member having a slot formed therein through at least a portion of the thickness of the bar member, with the slot extending from an attachment end to a nose end of the bar member. The saw bar also has a channel assembly, such as a tubular channel assembly, positioned in cooperation with the slot to deliver fluid from the attachment end to a channel outlet. In one embodiment, the saw bar has an idler sprocket pivotally mounted within a sprocket mounting slot formed at the bar member nose end. The channel outlet opens into the sprocket mounting slot to deliver lubrication fluid to the sprocket teeth. In an alternate embodiment, the channel outlet comprises a plurality of apertures along the length of an exposed wall of the channel member.
