LER/DORT: multifatorialidade etiológica e modelos explicativos

Parte-se de uma breve revisão bibliográfica sobre as LER/DORT (Lesões por Esforços Repetitivos/Doenças Osteomusculares Relacionadas ao Trabalho), analisando os fatores etiológicos envolvidos e os modelos explicativos vigentes. Discute-se a proposta de uma abordagem integradora de fatores biopsicossociais envolvidos na gênese e evolução das LER/DORT. Considera-se que a transição do estudo dos fatores isolados para a consideração de formas dinâmicas de interação desses fatores possibilitará a evolução da atual abordagem multidisciplinar para um modelo transdisciplinar.

Mancha-foliar-de-Phyllosticta em gengibre. caracterização cultural do patógeno e efeito de tratamentos químicos no controle da doença em Morretes, Estado do Paraná

The objectives of this work were to determine the micelial growth curve of the pathogen and the sensitivity to some fungicides potencially efficient to disease control. The optimum temperature range for micelial growth of Phyllosticta sp, was between 25 and 27.5 degrees C. The maximum and minimum temperatures for micelial growth were 32.5 degrees C and 10 degrees C. Temperatures of 5 and 35 degrees C completely inhibited the growth of the isolates. Total inhibition of the micelial growth was observed with captan and mancozeb (1000 mg a.i./ml) and triadimenol (100 mg a.i./ml). Partial reduction of the micelial growth was observed with iprodione, methyl tiofanate and chlorothalonil until 1.000 mg/ml. The chemical control of PLS was studied in a commercial area of ginger ''Gigante'', in Morretes, PR, where 18 sprays were carried out, with a break of 7 to 10 days, from December to April. The highest reduction of the area under the disease progress curve standardized (AUDPCs) was observed with the spray of chlorothalonil. With the application of dithianon, cupper oxychloride, folpet, mancozeb and captan it was observed AUDPCs between 15.05 and 18.61 lesions/leaf. Iprodione, benomyl, triadimenol and methyl tiofanate did not control the disease (AUDPCs between 20.03 and 25.04 lesions/leaf). The AUDPCs in the check plot was 35.88 lesions/leaf. There was no significant difference of vigor and of ginger yield between fungicide treatments. The cupper oxichloride was phytotoxic to ginger.
