Peanut (Arachis hypogaea L.) is an important crop for the family-based systems in the tropics, mainly in Brazil. In the Brazilian drylands, peanuts are cropped in low technological systems, and cheap and efficient technologies are needed to improve crop yield and sustainability. Despite this importance, few data are available on selecting efficient peanut rhizobia in experiments under different edaphoclimatic conditions. This work evaluated the agronomic efficiency and the biological nitrogen fixation (BNF) by two elite Bradyrhizobium strains under four different fields in the Brazilian semiarid region. We compared a new efficient strain Bradyrhizobium sp. ESA 123 with the reference strain B. elkanii SEMIA 6144, currently used in peanut rhizobial inoculants in Brazil. Besides the inoculated treatments, two uninoculated controls were assessed (with and without 80 kg ha−1 of N-urea). The BNF was estimated by the δ15N approach in three out of four field assays. BNF contribution was improved by inoculation of both Bradyrhizobium strains, ranging from 42 to 51% in Petrolina and 43 to 60% in Nossa Senhora da Glória. Peanuts? yields benefited from the inoculation of both strains and N fertilization in all four assays. Nevertheless, the results showed the efficiency of both strains under different edaphoclimatic conditions, indicating the native strain ESA 123 as a potential bacterium for recommendation as inoculants for peanuts in Brazil, mainly in drylands. |

(Damage characterization and control tactics to broad mite (Polyphagotarsonemus latus Banks) in Paraguaytea plants (Ilex paraguariensis A.St.-Hil.)). The broad mite (Polyphagotarsonemus latus) is referred as one Paraguay-tea (Ilex paraguariensis) pest, an important culture in the south of Brazil, and not existing studies about its control in the Paraguay-tea culture, the present work aimed to characterize the damages and to evaluate control tactics of this pest of Paraguay-tea seedlings, in green house. In the experiment 1, the Paraguay-tea seedlings were divided in two groups of 50 seedlings, divided in 5 repetitions. In one of the groups the seedlings were artificially infested with mites grown in laboratory. Weekly, during 3 months, the plants were appraised, the alterations possibly related to the mites presence were observed. In the second experiment, an identical group of seedlings was infested by the broad mite and 15 days after the following treatments were applied: a) mitecide based on cyhexathin, b) Hirsutella thompsonii fungus isolated CG 541 (1×106 conídios/mL), c) distilled water and d) without infestation, considered control treatment. The evaluations accomplished were before and at the end of the experiment, consisting in counting the mites in 10 leaves/repetition, determination of the height and number of leaves/plantings and dry weight of all the plants (end). The mites concentrated on the abaxial surface of the apical and younger leaves, which presented the screw borders, abnormal ribs development, rough surface and tan. Early leaves fall was also observed. There was no difference in the size of the plants and leaves number, but a 30% biomass reduction in the fungus treatment plants and in those without treatment has happened. The broad mite caused damages to the seedlings in nurseries and the mitecide control reduced the population of the same and the damages.
