TENACITY AND PERSISTENCE OF COPPER FUNGICIDES IN CITRUS SEEDLINGS UNDER SIMULATED RAINFALL

The amount of fungicide that adheres to the leaf during spraying and the amount that remain on the leaf after weathering are the main factors that defines the amount of active residue on the leaf surface to effectively control plant pathogens. Thus, the objective of this work was to evaluate the ten...

Abstract: The amount of fungicide that adheres to the leaf during spraying and the amount that remain on the leaf after weathering are the main factors that defines the amount of active residue on the leaf surface to effectively control plant pathogens. Thus, the objective of this work was to evaluate the tenacity and persistence of copper in citrus seedling leaves under simulated rainfall in Jaboticabal, State of São Paulo, Brazil. The evaluated variables were copper content, solution retention, surface tension and drop spectrum. A significant and inversely proportional linear relationship to drops
Translated abstract: A quantidade de produto que adere a folha durante a pulverização e a quantidade de material que permanece na folha após a ação de intempéries são os principais fatores que determinam a quantidade do resíduo ativo na superfície das folhas para um efetivo controle de fitopatógenos. O objetivo deste trabalho, conduzido em Jaboticabal – SP, foi avaliar a tenacidade e persistência de cobre em folhas de mudas cítricas sob ação de chuva simulada. Foram analisadas as variáveis: teor de cobre, retenção de calda, tensão superficial e espectro de gotas. Observou-se relação linear inversamente proporcional e significativa ao volume de gotas
