Efficiency of reduced volume spraying aimed to control the Leucoptera coffeella...
Lasmar, Olinto; Ferreira, Marcelo da Costa; Decaro Junior, Sergio Tadeu; Fouquet, GuntherThe objective of the study was to evaluate the application efficiency with reduced volume from the prototype of a pneumatic spray nozzles aimed to control the coffee leaf miner (Leucoptera coffeella). We evaluated different types of pneumatic nozzles (flat fan, cone jet, AT-1000 model and effervescent), on application of insecticide spray liquids with concentrations of 5, 10, 15 and 20% (v/v) of mineral oil app...

Decaro Junior, Sergio Tadeu; Ferreira, Marcelo da Costa; Lasmar, Olinto; Fouquet, GuntherThe present work evaluated reducing on spray volume for the control of Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842; Lepidoptera: Lyonetiidae) in coffee. Were used a conventional sprayer to apply the volumes 400 and 200 L ha-1 and an ultra-low-volume (ULV) sprayer to apply 46, 67 and 92 L ha-1. Sprays utilized 800 mL.ha-1 of the insecticide profenofos+lufenuron. The tracer MnSO4 was mixed to the...
