Excerpt from Causes, Effects and Control of Defoliation on Tomatoes<br/><br/>In all years at least four replicate plots of ten or more plants each were used for each treatment. A wheelbarrow hand sprayer was used prior to 1934, but from on, excepting where otherwise stated, the sprays were applied with a power outfit with three nozzles per row, 300 pounds pressure, 300 gallons per acre. Sprays were standardized at one pound of copper per 50 gallons making six pounds of copper per acre per application. The standard of ref erence was 4-4-50 bordeaux mixture. On some plots in 1938, 1939 and 1941 a knapsack sprayer (cali spray) developing 150 pounds pressure was used. In taking yield records the apparently ripe fruits were picked once a week, counted and weighed. The picking posed a technique problem not yet completely solved. An attempt was made to pick only ripe red fruit, but this was not easy on defoliated plants, where the fruits invariably developed an orange cast. AS a result the criterion of ripening was not always the same for all plots. The picked fruits were frequently sorted for cracks, or fruit diseases or spray injury. At the end of the season the green fruits also were picked, counted and weighed. In some years the green weight of vines was also recorded at the end of the season. In some seasons the fruit was graded according to U. S. Standards.
