Description
Summary:The objective of this study was to evaluate the influence of spray nozzles on solution deposition on targets positioned on different plant parts with distinct architectures. An experiments were conducted in a 2 x 3 x 3 randomized block design, consisting of two crops (corn and soybeans), three sites for deposition of the spray solution on plants the (upper third, middle third and bottom third) and three spray nozzles, with four replications, totaling 72 experimental units. The analysis of variance showed a significant effect on the triple interaction between the factors studied. The spray nozzles that produce fine droplets indicated better deposition of the solution on the different portions of the soybean and corn plants, with consequent higher coverage of the target. All nozzles used in this study resulted in spray deposition considered satisfactory for most pesticide applications.
