Abstract: two experiments were carried out in guava orchards cv. 'paluma' at monte alto and vista alegre do alto/sp. in experiment 1 it was used copper fungicides applied alone and in combination with mancozeb to evaluate the effect of phytotoxicity on floral buds and guava fruits in three developmental stages. in experiment 2 it was used the same fungicides used in experiment 1, plus a treatment with tebucunazole in order to evaluate the rust control. in experiment 1 none of the fungicides tested caused phytotoxicity symptoms and abortion of fruits less than 15 mm in diameter. the fungicides caused higher phytotoxicity in fruits between 25 and 35 mm but not in fruits larger than 40 mm diameter. copper fungicides combined with mancozeb lead to a slight toxicity, but when applied the mancozeb alone did not lead to phytotoxicity sympton. in the experiment 2, it was observed that copper fungicides applied alone were efficient to control rust as well as the combination of mancozeb and cuprous oxide or hydroxide and the fungicide tebuconazole.

Abstract: The purpose of the present study was to analyze the contribution of both exproprioceptive visual information and seat height in the control of stand-to-sit movement in young and older adults. Twelve older and 11 young individuals were invited to sit down on a chair under two seat heights (100% and 80% of the knee-ground distance) and under two visual conditions (with and without the availability of exproprioceptive visual information). Participants wore special goggles that reduced the size of the lower visual field. Participants performed the stand-to-sit movement with their feet positioned on a forceplate. The results allowed for the conclusion that the exproprioceptive visual information availability affected differently the way young and older adults control the stand-to-sit movement. On the other hand, seat height manipulation resulted in similar strategies by young and older individuals. Yet, older individuals exhibited a more conservative behavior than young adults while performing the stand-to-sit movement. O objetivo deste estudo foi analisar as contribui es da informa o visual exproprioceptiva e da altura do assento no controle do movimento de sentar em adultos jovens e idosos. Doze indivíduos idosos e onze adultos jovens foram convidados a sentar em uma cadeira sob duas alturas diferentes (100 e 80% da distancia do joelho até o ch o) e sob duas condi es visuais (com e sem a disponibilidade da informa o visual exproprioceptiva). A informa o visual exproprioceptiva foi manipulada através do uso de um anteparo visual posicionado logo abaixo do olho que reduziu o tamanho do campo visual inferior. Os participantes realizaram o movimento de sentar com os pés posicionados sobre uma plataforma de for a. Os resultados permitem concluir que a disponibilidade da informa o visual exproprioceptiva afeta de forma diferente o controle do movimento de sentar em adultos jovens e idosos. Por outro lado, a manipula o da altura do assento gerou estratégias de controle semelhantes em adultos e idosos. Ainda, os idosos exibiram um comportamento mais conservador durante a realiza o do movimento de sentar.

Abstract: in irrigated agriculture inadequate uniformity of water application in irrigation systems provides an excess of one part of the acreage and a deficit in another, reducing the availability of water to corn and increasing the cost of production. the objective of this study was to evaluate in the field the performance of systems for conventional sprinkler irrigation in the south of the state of espírito santo. five irrigation projects with conventional sprinkler irrigation were chosen randomly. each project was tested for uniformity of application of water by determining several coefficients of uniformity (coefficient of uniformity of christiansen, coefficient of statistical uniformity and coefficient of uniformity of distribution), and for the efficiency of application of water. the results show that 60% of the irrigation projects with conventional sprinkler irrigation evaluated presented low uniformity of application of water; that the depth of water applied in the appraised period is superior to the required depth for the plant; and that the average of the application efficiency in the projects was 71.88%, below the 75% recommended in the literature as the acceptable minimum.
