Studies were conducted in 1989 and 1990 in wheat stored on farms in Kansas and Oklahoma to compare the recommended harvest-time application of grain protectant with a delayed application (4-6 wk after harvest) to a portion of the grain mass. In 1989,

Pitfall traps and grain samples taken with a vacuum probe provided data on insect infestation in farm-stored wheat in 26 Kansas counties. Insects were monitored at 65-d intervals from July 1986 through March 1987. Early detection when populations wer

The quantity of grain in storage has been exceptionally high through much of the early 1980s. As a result, the effect of insect activity on quality of grain that is stored for long periods of time has become a major concern. The purpose of this study

In the past, foods were prepared in home kitchens to feed a relatively small number of people. Today’s food preparation occurs in large processing facilities and may involve feeding millions of people. This potential for affecting the lives and wel

The relationship between sample characteristics and the likelihood of a price discount was examined for samples of farm-stored wheat taken as it was delivered for sale to elevators in Kansas during 1986 and 1987. Lower test weight, as well as increas
