In 1959 two cotton pest trials were carried out in northern Queensland and during 1959-60 four in south-western Queensland. All trials were in irrigated crops. One involved fruit-form removal, three covered the effects of insecticide applications on yields, and two were screening trials for kills of Earias huegeli Rogen. In two of the insecticide trials fruit-form production studies were also made. The trial concerned with fruit-form removal indicated that early season loss of fruit forms did not adversely affect yields in irrigated cotton in northern Queensland. Yield trial results showed that reasonable commercial control of the major pest species, E. huegeli and H eliothis annigera (Huhn.) in northern Queensland and E. huegeli and H. punctigera Wallengr. in the south-west, is possible by using DDT and endrin. The screening trials proved that of the materials tested, "Telodrin" is the only one likely to improve commercial control of E. huegeli. Fruit-form production studies proved that although insecticides give considerable yield increases, the basic problem in both areas is the inability of the cotton varieties in use to produce regularly under current cultural conditions the fruit forms necessary for high potential yield.

Concentrate spray trials in 1962 using low volume application rates substantiated the previous year's encouraging results with this new pest and disease control technique. In field trials for control of several major pests in deciduous fruit and nut crops, concentrate spraying with chemicals applied at 60 gallons per acre offered control equal to that obtained with conventional “dilute” spray rigs applying the same chemical concentration in a total of 400 gollons of spray per acre.

Avocado trees are subject to fruit drop from hot weather. Field tests recently made in an avocado orchard, using overhead sprinklers for evaporational cooling, were effective in modifying air temperatures sufficiently to indicate possible control of this disorder. Temperature reductions of 5° to 7° were obtained.

The Food Processing Abstracts were available on a subscription basis from Lowry-Cocroft Abstracts based in Evanston, Illinois. Each week subscribers received abstracts, alphabetized and numbered in order, coded by a classification system. The code numbers appeared on the lower right hand corner of each card. The classification system had three divisions: Processing Fields, Type of Food Processed, and Kind of Information Included. -- Processing Fields subjects consisted of pasteurization, heat sterilization, freezing, dehyrofreezing, dehydration and concentration, freeze drying, preservation with chemicals (including salt), fermentations (excluding alcoholic beverages, separation and refining, irradiation, enzyme treatment, packing, packaging, cooking and baking, and organoleptic analysis. -- Types of Food Processed subjects were vegetables, fruit and fruit products, meat, poultry, fish and shellfish, eggs, dairy products, cereals and soy beans, starch, sugar and confections, beverages, oils and fats, spices and flavorings, prepared foods, diet foods, other foods, and baked goods. -- The Differentiation by Kind of Information covered field included patent, legal, quality control, microbiology, time and temperature processing, equipment, storage, flavor, texture, color, nutritive value, antioxidants, emulsifiers and stabilizers, other additives, composition and analysis, and consumer preference. -- Information was retrieved by use of a sorting needle. For instance, if it was desired to obtain all the articles on the subject of freeze drying, the needle was inserted in hold 23 and the desired cards, on which this number was notched, dropped out. If only the articles on freeze drying of meat products were desired, a second use of the needle in hole 49 of the separated cards isolated those. Again if it was desired to refer only to patents on freeze drying of meat, a third use of the needles in hold 29 segregated those.
