Item Extração do óleo fixo do Syagrus cearensis Noblick e atividade inseticida sobre o Callosobruchus maculatus em feijão armazenado(2019) Lemos, Cleide Maria de; Silva, Renato Augusto da; http://lattes.cnpq.br/5111987334920733The Cowpea bean, Vigna unguiculata, has an extraordinary role in feeding the population of the North and Northeast regions of the country. However, this crop is still harmed by the significant loss of production due to insect pest attack and poor product quality due to the use of synthetic chemical pesticides. In the present work the effect of the oil of the catolé Syagrus cearensis Noblick as natural defensive was studied on the carouscho Callosobruchus maculatus in cowpea, both purchased in the city of São José do Belmonte, sertão of Pernambuco. The methodology can be reproduced in domestic environment since the oil of catolé is used in cooking and folk medicine and there are no reports of intoxication. For the bio-insecticidal tests only plastic containers, syringes and household scales, all of low cost and commercially available, were used. The concentration of 0.0 mg to 123.2 mg of the oil per 20g of beans were analyzed and as a result the Lethal Concentration (LC50) = 64.96 was estimated using the "trend line" option of the Excel 2010 program, Office, Microsoft. The good results presented here, where there was 100% mortality of C. maculatus with the dosages of (88.0 mg and 123.2 mg), revealing that the catolé oil is an economically viable bioinseticide and accessible for the handling of the caruncho on stored cowpea beans.Item Avaliação da biomassa de plantas de cebola cv. 1205 e cv. Serengeti em solos conducentes à nematose tratados com produtos biológicos(2019) Soares, Maurício Meira; Albuquerque, Neilza Reis Castro de; http://lattes.cnpq.br/3614090907577987The onion Allium cepa highlights-like vegetable important socioeconomic for the country, the predominance of culture medium, small producers and the family nature, generating about 250 thousand direct jobs in production. How the culture has its phytopatological problems, the decision has been made for the economics made from the production of the largest production in production. In order to control the problems, the tests are being studied and the biological control of the main focus is the use of nematological bacteria and fungi that promote the protection of the roots of the growth, besides promoting an increase in the biomass of the plants. The use of the microorganisms may have had an important relation with the potential of soil management, cleaning of the ecosystem of systems and the suppressive. The objective of this study was to evaluate the biomass of hybrid 1205 and Serengeti crop plants grown on soils with three biological products. Three bioproducts will be tested: product 1 containing bacteria: Bacillus pumilus 1.0x10¹¹ (endospores / L), Bacillus subtilis1.0x10¹¹ (endospores / L) and Bacillus amyloliquefaciens 1.0x10¹¹ (endospores / L), Product 2 have the bacteria Azospirillum sp. 1.0x109 (UFC / dose), Pseudomonas sp. 1.0x109 (CFU / dose), Rhizobium sp. 1.0x109 (CFU / dose) and the fungus Saccharomyces sp. 1.0x109 (CFU / dose) and product 3 is a base of Bacillus subtilis1.0x10¹¹ (CFU / g) and Bacillus licheniformis 1.0x10¹¹ (CFU / g). After 60 days, morphological variables were identified as buyer of aerial and root parts, diameter of pseudocaule and bulb, weight of fresh matter and dry material and finally determined the index of galls formed not root system. The results obtained showed that the biomass concentrations between the plants cultivated in soils and with the bioproducts were concluded in comparison with the biomass among the hybrid cultivars of onion cv. 1205 and cv. Serengeti.Item Avaliação da biomassa de plantas de goiabeira cv. paluma tratadas com produtos biológicos em solos conducentes à Meloidogyne spp(2019) Souza, Daniel Ericles dos Anjos; Albuquerque, Neilza Reis Castro de; http://lattes.cnpq.br/5706869625614564; http://lattes.cnpq.br/1272248073820183The cultivation of guava (Psidium guajavaL.) is widespread throughout the world, [being a kind of reality with high economic and market potential, which, with this, still presents great possibilities of expansion around the world.]In Brazil, São Paulo and Pernambuco lead production, accounting for 36.3% and 31%, accounting for 67.3% of national production. However,diseases in guavain Brazil directly influence the productivityof this culture. Among the diseases, meloidoginose is one of the main causes of damage to guava producers. In this context, the work was evaluated as the aerial biomass problem and root portion of guava seedlings of cv. Paloma for two soil conditions leading to the three biological products. Soils were grown in areas of guiding guava in nematodes under two management, soil 1 with remnant characteristics and soil 2 in full culture, deposited in 10 L volume vessels that are projected with three products formulated with Bacilluspumilus, B. subtilis, B. amyloliquefaciens, Azospirillum sp., Pseudomonas sp., Rhizobium sp., Saccharomyces sp., B. licheniformis. With the end of the 90 days, with the measurement of the first planes, the fresh mass and the dry and dry mass, the diameter of the stem, pair of leaves, number of leaves and number of branches. The experiment was carried out without a randomized complete block design (DBC) with eighttreatments and four replications where the treatments, arranged in a factorial scheme 4 x 2. The results were those biological products tested in this experiment, not having as parameter the biomass differences in question relation to the two types of cultivated soils.
