Beetle from Australia threatens eucalyptus

by Glenn T. Scriven, Eldon L. Reeves, Robert F. Luck

Abstract

Long free of major pests, southern California eucalyptus is now being attacked by eucalyptus longhorn borer.

Spreading rapidly in southern California

Fungicidal control of tomato blackmold under rainy conditions

by Eugene M. Miyao, Dennis H. Hall, Prudence Somerville, Nancy Blaker

Abstract

Three fungicides were effective in preventive treatments.

Fungicides as preventive sprays significantly reduced incidence of blackmold

Determining crop yield losses from air pollutants

by Patrick M. McCool, Robert C. Musselman, Roberto R. Teso, Ronald J. Oshima

Abstract

Yield-loss data produced by tests in field chambers show effects of various ozone levels on specific crops.

Measurements in field chambers reveal losses to pollution

Farmworker unions: Status and wage impacts

by Philip L. Martin, Suzanne Vaupel, Daniel Egan

Abstract

Seven unions representing 14 percent of California farmworkers have had significant but varied effects on wages.

Effects on wages have been significant but limited

Molecular studies of fruit ripening

by Roger Romani, Betty Hess

Abstract

Fruit cells in liquid culture undergo some ripening changes much as whole fruit do and are easier to manipulate.

Cultured pear fruit cells growing in a liquid suspension provide a useful model

Fungicides for control of powdery mildew in cucurbit…

by Albert O. Paulus, Curtis E. Engle, Faustino Munoz, Jerry Nelson, Harold W. Otto, Aziz Baameur

Abstract

Several fungicides gave good control, although Bayleton seemed less effective in 1984 and 85 than in 82 tests.

Several new materials show promise

Fungicides for control of powdery mildew in tomato

by Albert O. Paulus, Robert W. Scheuerman, Faustino Munoz, Philip Osterli, Wayne L. Schrader, Harold W. Otto

Abstract

Several fungicides tested controlled the disease, but growers should also look for tolerant tomato cultivars.

Managing powdery mildew and rust on sunflower

by Demetrios G. Kontaxis

Abstract

Two fungicides controlled powdery mildew and one controlled rust in a field test on sunflower.

Turfgrass performance under reduced irrigation

by Jewell L. Meyer, Victor A. Gibeault

Abstract

Potential water savings are greater with warm- than cool-season grasses.

Verticillium wilt of pistachio

by Lee J. Ashworth, David P. Morgan, Earl Surber

Abstract

Phosphorus- or potassium-deficient pistachio trees are very susceptible to low levels of Verticilliumin soil.

Proper nutrition reduces infection in low-inoculum soils and improves yields

Root-knot nematode resistance in processing tomatoes

by Philip A. Roberts, Donald May, William C. Matthews

Abstract

Several tomato cultivars show good tolerance of root-knot infection and might be useful in nematode management.

Cultivars with the Mi gene for resistance showed excellent tolerance of root-knot nematode injury

Evaluation of low-flow sprinklers

by Steven E. C. Post, Donald E. Peck, Robert A. Brendler, Nicholas J. Sakovich, Lee Waddle

Abstract

Tests with catch cans indicated the geometric arrangement and method analysis closest to “true” uniformity.

The variegated leafhopper, an increasing pest of grapes

by William H. Settle, Lloyd T. Wilson, Donald L. Flaherty, Greg M. English-Loeb

Abstract

This leafhopper escapes control by the parasitic wasp Anagrus epos largely because of its egg-laying behavior.

More serious than the grape leafhopper
