Abstract: RESUMO -O trabalho foi desenvolvido visando avaliar os parâmetros da pulverização em culturas arbóreas.A eficiência e a deposição de gotas sobre o alvo são importantes para elevar a rentabilidade na produção de madeira, diminuindo os riscos ambientais, e para a saúde do aplicador, aumentando a eficácia no combate de pragas e doenças. O objetivo deste trabalho foi avaliar os parâmetros operacionais de um pulverizador pneumático para aplicação em florestas adultas de eucalipto, através do estudo da densidade de … Show more

“…According to Zhang et al (2020 a), satisfactory control of a pest or disease is achieved when an adequate quantity of droplets is deposited on the target; however, this amount depends on the crop protection product used, and in particular its form of absorption and translocation. Although the droplet density obtained with the UAV may be considered adequate for many products (according to the recommendation by Mewes [22] et al), target coverage was low (although there are no predefined optimal coverage values for each class of product), which may compromise treatments using contact products or products with low systemicity. Systemic fungicides, for example, exhibit limited translocation in soybean plants and need to be evenly distributed throughout the canopy.…”

“…As aplicações de defensivos em sistemas florestais têm ganhado destaque com a grande expansão da cultura do eucalipto (MEWES et al, 2013). Além disso, atualmente vem sendo utilizado a mistura de herbicidas com fertilizantes foliares (MACHADO et al, 2017).…”

“…A boa adaptação às condições climáticas brasileiras faz com que o plantio de florestas do gênero Eucalyptus se espalhe por todo território nacional (GARLET et al, 2013). Por outro lado, relatos de surtos de insetos herbívoros nativos e exóticos têm aumentando nos últimos anos, consequentemente aumentando o número de aplicações de agrotóxicos nas florestas plantadas (MANSFIELD, 2016;MEWES et al, 2013).…”
