Manejo de plantas daninhas na cultura do mamoeiro Weed control in papaya

Abstract

Apesar de o controle de plantas daninhas na cultura do mamoeiro representar um dos componentes de grande importância do custo de produção, no mundo e no Brasil, a disponibilidade de informações sobre esse tema é escassa, o que reflete a pouca importância que tem sido dada ao assunto nas últimas décadas. Neste texto são discutidos alguns avanços no manejo integrado de plantas daninhas que têm sido alcançados em vários países, particularmente no tocante à manutenção da vegetação natural ou à introdução de leguminosas na entrelinha de cultivo. Não obstante, várias espécies de plantas daninhas foram identificadas como hospedeiras de vetores de importantes viroses à cultura, com destaque para Commelina benghalensis e Solanum americanum. Isso se reveste de grande importância para o manejo (seletivo) das plantas daninhas, sobretudo na produção integrada de mamão. Também são discutidos, em especial para a região norte do Estado do Espírito Santo, a seletividade de herbicidas, os períodos de controle e as principais características e aspectos práticos sobre o manejo de plantas daninhas na cultura do mamoeiro.Despite the fact that weed control entails high costs to crop production, the availability of national and international papers regarding papaya weed control is scarce, showing that little importance has been given to this subject in the last decades. Some integrated weed management advances attamed in several countries are discussed, particularly in the use of both natural groundcover or leguminous plants in the crop interrows. However, several weed species have been identified as host plants of major virus vectors to the crop, such as C. benghalensis and S. americanum. Such information is of major importance for selective weed control, particularly in the integrated system of papaya production. The present review also examined herbicide selectivity, weedy periods as well as the main characteristics and practical aspects of weed control in papaya, focusing on the production areas of the northern Espírito Santo State.
