| ABSTRACT Climacteric fruits have short postharvest shelf life. Coating is an alternative to minimize fruit ripening and post-harvest losses. Maize starch (S) and polivinilic alcohol - PVOH (P), isolated or blended, can be used in the formulation of coatings. However, little is known about the potential of PVOH-containing coatings in postharvest conservation of fruits. Papaya were aftercoated with 5 coating formulations: 3% starch (S), 3% PVOH (P), 2.25% S + 0.75% P, 1.5% S + 1.5% P and 0.75% S + 2.25% P. The fruits were kept at room temperature (20 ± 5 °C and 70 ± 10% RH) and physicochemical characteristics were evaluated for up to eight days. Uncoated fruits were used as control. In general, maize starch and PVOH. In general, maize starch and PVOH... |

| Os clamidósporos são os principais propágulos utilizados como fonte de inóculo de Pochonia chlamydosporia em experimentos envolvendo o biocontrole do nematoide das galhas. O presente trabalho teve por objetivo avaliar o controle de Meloidogyne javanica em tomateiro por meio da aplicação ao solo de grãos de arroz colonizados pelo fungo contendo apenas micélio e conídio, sem a presença de clamidósporos. O isolado de P. chlamydosporia Pc-10 foi cultivado por 15 dias a 26°C em arroz previamente esterilizado em forno microondas. Dois experimentos foram conduzidos simultaneamente em casa de vegetação. No experimento 1, vasos de 2L de capacidade foram preenchidos com mistura solo:areia (1:1, v:v), contendo 3g kg-1 de solo de grãos de arroz colonizados pelo... |

| ABSTRACT: The accurate identification of root-knot nematode (RKN) species (Meloidogyne spp.) is essential for implementing management strategies. Methods based on the morphology of adults, isozymes phenotypes and DNA analysis can be used for the diagnosis of RKN. Traditionally, RKN species are identified by the analysis of the perineal patterns and esterase phenotypes. For both procedures, mature females are required. Over the last few decades, accurate and rapid molecular techniques have been validated for RKN diagnosis, including eggs, juveniles and adults as DNA sources. Here, we emphasized the methods used for diagnosis of RKN, including emerging molecular techniques, focusing on the major species reported in Brazil. |

| Greenhouse experiments were conducted to evaluate the effect of soil amendment with chopped (1cm²) or ground (1mm sieve) dry leaves of assa-peixe (Vernonia polyanthes), lemon-grass (Cymbopogon citratus), eucalyptus (Eucalyptus citriodora), castor (Ricinus communis), mango (Mangifera indica) or neem (Azadirachta indica) for the control Meloidogyne javanica. Into the soil (Yellow red oxisol) of each pot were added leaves (5g kg-1 of soil) and 5,000 eggs of the nematode. After seven days, one tomato seedling "Santa Cruz Kada" was transplanted to each pot. The tomato root weight, galls and eggs/root system were determined 60 days after transplant. None of the soil amendments reduced gall or eggs, when applied as leaf pieces. However, all tested plant species... |
