Control of Oriental fruit moth by mating disruption

by Craig V. Weakley, Philipp Kirsch, Richard E. Rice

Abstract

Confusing the male Oriental fruit moth by flooding peach orchards with the female's pheromone provided excellent control of the insect and may be an alternative to conventional insecticide use.

The California-Arizona lemon cycle continues

by Hoy F. Carman, Richard D. Green, William Kinney

Abstract

Projections of the lemon cycle indicate that average total revenue per acre in 1998–99 will drop to the same level seen in 1984–85, if growers continue to respond as they have in the past.

Fungicides for leafspot control on strawberry

by Marvin J. Snyder, Albert O. Paulus, Victor Voth, Jerry Nelson

Abstract

Two currently registered fungicides controlled common leafspot. Other materials tested showed promise.

Manger misting improves dairy cows' appetite

by Thomas A. Shultz, Stanton R. Morrison

Abstract

Misting also decreased losses in milk yield, reduced cow mortality after calving, and improved reproduction.

Selenium enhances lamb gains on sulfur-fertilized pastures

by Milton B. Jones, D. Michael Center, Victor V. Rendig, Martin R. Dally, Ben B. Norman, William A. Williams

Abstract

Large responses to sulfur can occur when nitrogen is applied to many California rangeland soils. Giving lambs selenium in pellet form significantly improved gain on such pastures.

Testing to predict tomato harvest worker performance

by Gregory Encina Billikopf

Abstract

A study of a group of tomato pickers suggests that a work-sample test could be useful in choosing harvest workers.

Groundwater flows to the San Joaquin River

by Elias A. Rashmawi, Mark E. Grismer

Abstract

Groundwater may represent only a fraction of one percent of the river's total annual flow.

Correcting potassium deficiency in prune trees is profitable

by William H. Olson, Kiyoto Uriu, Robert M. Carlson, William H. Krueger, James Pearson

Abstract

Even a slight deficiency can be costly. A single application of potash fertilizer can correct the deficiency for three to four years.

Resistance of the little house fly to insecticides on poultry facilities

by Jeffery A. Meyer, George P. Georghiou

Abstract
