Fruit rot, besides causing losses in production, reduces the final quality of the product interfering in the commercialization. The objective of this work was to evaluate the efficiency of alternative products applied to pre-harvest for control of brown rot (Monilinia fructicola) and soft rot (Rhizopus spp.) In peaches. The experiment was conducted in the municipality of Nepomuceno-MG, in a peach orchard of the cultivar Diamante. The experimental design was a randomized block design with 7 treatments and 3 replicates, with field plots formed by 12 plants (arranged in 3 rows), being considered for the evaluations only the two central plants. Three applications were made at flowering and at 21;7 and 3 days before harvest, with solutions containing the following treatments: 1-Clove oil 0.1%;2-silicate clay 1.5%;3-Phosphite K 0.20%;4-Benzalkonium chloride 0.25%;5-Azoxystrobin 0.02%;6-Iprodione 0.15%;7-Witness (water only). Treatments 4 and 5 were applied only at 21 and 7 days before harvest. Ten fruits were selected and placed in sterile trays under uncontrolled conditions, with disease evaluations at 3 and 6 days after the beginning of storage in 2005 and at 3;6 and 9 days in 2006. The iprodione controlled the incidence of M. fructicola and had no effect on Rhizopus spp. Clove oil controlled the incidence and severity of M. fructicola by the fifth day and Rhizopus spp. by the sixth day. The phosphites of k, benzalkonium chloride and azoxystrobin were efficient in controlling the incidence and severity of Rhizopus spp. and had no effect on M. fructicola. 展开更多

The objective of this work was to study the effect of different planting densities on the development and production of “Roxo de Valinhos” green figs for industry, in the Campo das Vertentes-MG region. The experiment was installed at the Risoleta Neves Experimental Field—CERN/EPAMIG. The plants used were three years old and were arranged in three randomized blocks, subject to three different planting densities, with spacings ranging from 1 m (4000 plants·ha-1), 1.5 m (2666 plants·ha-1), and 2 m (2000 plants·ha-1) between plants in the planting line and 2.5 m between row for all planting densities. The average length of the branches (m), average number of fruits per branch, average number of fruits per plant, average weight of fruits, average yield per plant and the average yield per hectare (kg) were evaluated. It was verified that, there were no significant differences in the length of branch and in the average weight of fruit, in the three densities of fig tree planting. (4000 plants·ha-1), the average number of fruits per branch (7.5), per plant (55.87) and yield per plant (878.93 kg) were lower, however. The average yield per hectare (3515.73 kg) was higher than in other growing densities. It is concluded that, the higher density of plants (4000 plants·ha-1), provides the highest productivity per area, without damages to the quality of the fruits. 展开更多
