Resumo:  This study was carried out at the Agronomic Experimental Station of Universidade Federal do Rio Grande do Sul, located in Eldorado do Sul, RS, southem Brazil (30°06' 5, 51°39' W) fromiuly 1989 to February 1990. The following soil treatments were tested: Methyl Bromide (50cm 3/m2),Fosetyl-Al (25g/101 water/m 2), Benomyl (10 g/10Iwater/m 2), and a control. Also mulching treatments were tested and consisted of: rice hull, straw, rice hull + straw, and a control. The number of seedlings emerged and the average plant height at 90, 120 and 150 days after sowing were evaluated. The experimental design was a split-plot in a randomized block with four replications, with the soil treatments as the main plots and mulching as the sub-plots. Results showed that Fosetyl- Al had the best performance among the tested products. Methyl Bromide provided good emergence but caused leaf chlorosis, rosette symptoms and reduced growth. With Benomyl there was low emergence, however did not reduce growth. All mulching treatments favored seedling emergence and did not affect average plant height.

Foram testados os seguintes sistemas de desinfestação do solo: Brometo de Metila (50cm 3/m2),Fosetyl-Al (25g/ 101 de água/m2), Benomyl (10 g/I O 1 de água/m2) e testemunha. Também se testaram métodos de cobertura do solo: casca de arroz, capim seco, casca de arroz + capim seco e solo nu. Foi avaliado o número de plântulas emergidas e altura média de planta aos 90, 120 e 150 dias após a semeadura. O delineamento experimental foi em parcelas subdivididas, constando os sistemas de desinfestação do solo nas parcelas principais e os métodos de cobertura, nas subparcelas. O Fosetyl-AI mostrou o melhor desempenho entre os produtos testados. O Brometo de Metila proporcionou boa emergência, mas causou clorose e sintomas de roseta (folhas eretas) nas plantas, reduzindo a velocidade de crescimento. O Benomyl induziu a uma baixa emergência, apesar de ter proporciónado uma boa velocidade de crescimento. Os métodos de cobertura do solo foram superiores ao solo nu, para o número de plântulas emergidas, não tendo sido verificado efeito significativo para a altura média de planta. Departamento de Diagnóstico e Pesquisa Agropecuária.
