Differential Plant Injury And Yield Responses Of Tomato Varieties To 2,4-D, D. P. Coyne, O. C. Burnside

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Experiments reported in this bulletin were conducted to determine the extent of plant injury and yield loss due to high and low rates of 2,4-D sprays on a wide range of home garden and processing tomato varieties. Results of this study could be used as a basis for suggesting tomato varieties suitable for growing in areas where 2,4-D drift is a common problem. An experiment was also conducted to determine if there was resistance to or good recovery from 2,4-D injury in other tomato species and in a wide collection of tomato plant introductions.

Production Costs In The Apple Industry : Comments On A Survey, A W. Hogstrom, I. J. Moncrieff

Journal of the Department of Agriculture, Western Australia, Series 4

IN 1964 and 1965, light and heavy bearing years respectively, apples cost $2.40 per bushel to produce in Western Australia. This figure, to be considered with many other factors, was reached in a cost-of-production survey of 45 selected growers.

Packing and labour costs, in that order, were the two biggest cost-of-production items.

THE pear leaf blister mite* may be causing widespread but undetected damage in Western Australian pear crops.

A bud-dwalling form exists which shows none of the leaf blisters normally associated with this species.
