G646 Sphaeropsis Tip Blight Of Pines, Loren J. Giesler

University of Nebraska-Lincoln Extension: Historical Materials

The symptoms and identification, disease cycle and control of Sphaeropsis tip blight.

Browning and death of tips is quite common in older, well-established pine plantings. Such damage is often due to Sphaeropsis tip blight, a fungal disease caused by Sphaeropsis sapinea (syn. Diplodia pinea). Infection kills major branches and may even kill the entire tree under severe disease pressure.

Sphaeropsis sapinea can infect young trees, but the disease becomes increasingly more common and destructive as trees approach 30 years of age. Tip blight commonly occurs in landscape, windbreak and park plantings; but is seldom found in natural pine stands. …

G90-990 Explosion Venting And Suppression Of Bucket Elevator Legs, David Jones

University of Nebraska-Lincoln Extension: Historical Materials

Explosion vents and explosion suppression devices limit the danger and damage associated with grain dust explosions. This NebGuide discusses these devices and design guidelines for application on bucket elevator legs.

The bucket elevator leg has been identified as a major source of grain dust explosions. As a bucket elevator leg conveys grain, the elements necessary for a grain dust explosion are possible. Fuel (grain dust in suspension above the minimum explosive concentration), oxygen and confinement are inherent inside a functioning bucket elevator leg. Introduction of an ignition source will initiate a grain dust explosion.
