No norte do Estado do Espírito Santo, vem sendo observada a ocorrência crescente da ferrugem (Puccinia psidii G. Winter) nos pomares de goiabeira, ocasionando a queda de frutos novos e o declínio na produção. Este trabalho teve como objetivo avaliar tratamentos com fungicidas no controle da ferrugem em goiabeiras 'Paluma' podadas em diferentes épocas do ano. Foram realizados três experimentos, em delineamento em blocos ao acaso, com diferentes épocas de poda de frutificação (janeiro; maio e outubro) e quatro tratamentos fungicidas (I- testemunha - aplicação de água, II- oxicloreto de cobre, III- tebuconazole e IV- tebuconazole + oxicloreto de cobre). Observou-se que, quando a poda foi realizada em janeiro, houve as maiores incidências máxima e final da doença, acarretando menor número de frutos por planta. Dentre os fungicidas testados, tebuconazole isolado ou em mistura com oxicloreto de cobre foram os mais eficientes em controlar a doença nas três épocas de poda, inclusive na época de maior incidência da doença. Quatro pulverizações com tebuconazole, isolado ou em mistura com o oxicloreto de cobre, foram suficientes para minimizar os danos causados pela ferrugem da goiabeira.
In the north of Espírito Santo State, Brazil, increasing occurrence of rust (Puccinia psidii G. Winter) has been observed in guava trees, causing fruit drop and yield losses. The objective of this work was evaluate the incidence and chemical control of guava rust in 'Paluma' guava trees pruned in different seasons. Three experiments were carried out in a randomized complete block design, with three different pruning times (January; May and October) and four fungicide spraying treatments (I - untreated check, II - copper oxychloride, III - tebuconazole and IV - tebuconazole + oxychloride copper). Plants pruned in January showed the highest maximum and final guava rust incidences and smallest number of fruits per plant. Regardless of pruning time, the effective rust control occurred in plants sprayed with tebuconazole and tebuconazole plus copper oxychloride fungicides. Four sprayings with tebuconazole pure or mixed with copper oxychloride were sufficient to mitigate the damage caused by guava rust.

Among the most serious problems in papaya production are the viruses associated with papaya ringspot and papaya sticky disease (PSD). PSD concerns producers worldwide because its symptoms are extremely aggressive and appear only after flowering. As no resistant cultivar is available, several disease management strategies have been used in affected countries, such as the use of healthy seeds, exclusion of the pathogen, and roguing. In the 1990s, a dsRNA virus, papaya meleira virus (PMeV), was identified in Brazil as the causal agent of PSD. However, in 2016 a second virus, papaya meleira virus 2 (PMeV2), with an ssRNA genome, was also identified in PSD plants. Only PMeV is detected in asymptomatic plants, whereas all symptomatic plants contain both viral RNAs separately packaged in particles formed by the PMeV capsid protein. PSD also affects papaya plants in Mexico, Ecuador, and Australia. PMeV2-like viruses have been identified in the affected plants, but the partner virus(es) in these countries are still unknown. In Brazil, PMeV and PMeV2 reside in laticifers that promote spontaneous latex exudation, resulting in the affected papaya fruit?s sticky appearance. Genes modulated in plants affected by PSD include those involved in reactive oxygen species and salicylic acid signaling, proteasomal degradation, and photosynthesis, which are key plant defenses against PMeV complex infection. However, the complete activation of the defense response is impaired by the expression of negative effectors modulated by the virus. This review presents a summary of the current knowledge of the Carica papaya-PMeV complex interaction and management strategies.
