Abstract: A safe and natural method to cure the fungal disease caused by the Taphrina deformans fungus known as peach leaf curl. This disease commonly effects and destroys the leaves and fruits of peach and nectarines trees. According to the present discovery, it has been found that Carvacrol, a constituent of the extracts derived from oregano and thyme plants, is an effective agent to eradicate peach leaf curl during the season of infection. Several (e.g., two or three) applications of an aqueous solution containing oregano oil or thyme oil (known commercially as Oil of Oregano and Oil of Thyme) has been found to cure the infected trees and save the current year's fruit crop for harvest.

Abstract: A multiple position rotary switch is disclosed for incorporation into an electrical device. The switch comprises an annular cup that serves as a housing for the switch and which receives a knob for rotation therein. The knob is retained within the cup by a circuit board that is removably secured to the cup. The circuit board includes a first major surface having a switching circuit formed thereon and a second major surface. The circuit board is removably secured to the cup by a plurality of barbed ears which extend from the sidewall of the cup such that the first surface of the board is located between the knob and the second surface of the board. The cup includes an upstanding sidewall and a race against which the knob rotates. The race includes a plurality of protrusions which facilitate the retention of the knob in preselected positions as the knob is rotated. The knob comprises a cylindrical disk having on one surface a handle.
