Leaves coverage of spray liquid and influence on herbicide efficacy
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014 The effect of spray liquid leaves coverage on efficacy of herbicides was investigated. Five nozzles sizes were used to reach different percentage coverage. The effect of leaves coverage on Elytrigia repens (L.) Desv. was evaluated using systemic herbicide (clethodim 240 g / l + surfactant) and the effect of leaves coverage on Chenopodium album L.

Use of spray target cards and leaf analysis to measure spray coverage
California Agriculture, 1973 This report evaluates a method used to determine the uniformity of spray coverage in a pear fireblight control experiment in 1972. Trees used for the experiment were mature 14-year-olds in a hedgerow planting at 11 hy 22 ft spacing.
