Records document that in the past decade the diets of more than 100,000 low-income homemakers and their families in California have been measurably improved as a result of the Expanded Food and Nutrition Education Program (EFNEP).

The introduction of a seed weevil and a stem-boring weevil has had mixed results in the reduction of puncturevine, a spiny-burred weed that can injure grazing animals ingesting them, and can downgrade the value of land, alfalfa hay crops, and wool. The weevils were imported from Italy in 1961.

Electrophoresis of grain proteins reliably identifies wheat varieties; electrofocus- ing provides additional information about protein composition. The speed of these methods promises to be valuable on many grounds: in international trade, in forensic and legal applications, and in regulating breeders' rights.

Soap detergent sprays can control certain insects on ornamental plants. They have limited residual action and may damage some plants.

Fungicidal treatments proved far more effective than no treatment in controlling Septoria apiicola, the fungus that afflicts California's celery during the rainy season.
