Root rot of Easter lilies: Preplanting fungicidal dip for lily bulbs reduces incidence of disease and improves bloom quality and quantity of plants
by J. G. Bald , Philip A. Chandler , John V. Lenz , R. H. Sciaroni , A. O. Paulus
pp3-14, doi#10.3733/ca.v012n04p3
Abstract

Wild safflower in California: Improvement of cultivated safflower through plant-breeding program to obtain desirable characteristics of wild species
by P. F. Knowles , Amram Ashri
pp4-5, doi#10.3733/ca.v012n04p4
Abstract
Abstract Not Available – First paragraph follows: Cultivated safflower — Carthamus tinctorius L.—was established in California as a commercial crop in 1950 and by 1956, approximately 84,000 acres were in production. Most of the acreage was in the Sacramento Valley but it is likely that the total acreage will increase because there is a good market for safflower oil.

Potato sprout inhibitor spray: Aircraft spraying of growth regulator maleic hydrazide is not effective means of reducing sprouting of stored potatoes
by Herman Timm
pp6-12, doi#10.3733/ca.v012n04p6
Abstract
Abstract Not Available – First paragraph follows: Maleic hydroxide — MH-40—effectively reduces storage losses of potatoes and onions but little use has been made of it as a growth regulator in potato growing in California.

Spray thinning Newtown apples: Properly timed and applied, spray treatment satisfactorily thinned fruit for size and yield in trials near Watsonville
by K. Uriu , O. Lilleland , E. C. Koch
pp7-8, doi#10.3733/ca.v012n04p7
Abstract
Abstract Not Available – First paragraph follows: Commercial size spray thinning trials with naphthylacetamide—Amid Thin—in 1956 and 1957 indicated that the material can satisfactorily thin Newtown apples, does not injure foliage, reduces hand thinning costs and can result in a better return bloom the following year.

Pelleted alfalfa hay: Baled and pelleted alfalfa hay in comparative trial with beef steers
by N. R. Ittner , J. H. Meyer , G. P. Lofgreen
pp8, doi#10.3733/ca.v012n04p8
Abstract
Abstract Not Available – First paragraph follows: Pelleting alfalfa hay for livestock reduces the bulk and transforms the hay into a free flowing form like grain and cuts labor requirements for handling.

Chamise control with aircraft: Herbicides applied by aircraft in spring following fall burn controlled chamise sprouts and brush seedlings in range test
by O. A. Leonard , C. E. Carlson
pp9-12, doi#10.3733/ca.v012n04p9
Abstract
Abstract Not Available – First paragraph follows: The use of aircraft to apply herbicides in the control of chamise and associated brush species—as a follow-up to controlled burning and seeding—was studied on a chamise dominated area. The test site was at a 1,400′ elevation in the foothills of the west slope of the Sierra Nevada, about 10 miles west of Placerville.

Filbertworm control trials: Two new insecticides tested on Payne, Franquette and Hartley walnuts in two experimental orchards in northern California
by Arthur H. Retan , George R. Post , Clarence S. Davis , A. E. Michelbacher
pp10-11, doi#10.3733/ca.v012n04p10
Abstract
Abstract Not Available – First paragraph follows: The intensity of the filbertworm infestation of walnuts in northern California in 1957 was less than in the peak year of 1954, but it marked the fourth straight year that the filbertworm has presented a problem. Based on past history the 1957 attack was surprising because observations have indicated that the pest would not continue at a highly destructive level over a period of several years.

by John H. Madison
