Foi avaliada a eficiência das dosagens de 1; 2,5 e 5 g/cova do fungicida Ridomil 50 gr (metalaxyl 50 g/kg), em aplicação única no solo, comparada com a dosagem de 400 g/100 litros de água do Fólio (metalaxyl + clorotalonil, 80 + 400 g/kg) e do Ridomil Mancozeb br (metalaxyl + mancozeb, 80 + 640 g/kg), em dez pulverizações, para o controle da requeima do tomateiro cv. Santa Clara. O delineamento experimental foi de blocos ao acaso com seis tratamentos e quatro repetições. A percentagem de área foliar lesionada pela requeima foi de 2,75% no tratamento com Folio, 7,25% com Ridomil Mancozeb br; 18,25; 18,50 e 24,25% com as dosagens crescentes do Ridomil 50 gr, e 34,25% com a ausência de tratamento com fungicidas (testemunha).

Como consecuencia del éxito comercial del chayote en los mercados de Norteamérica, la superficie de la producción nacional como monocultivo ha aumentado considerablemente, lo que ha generado la aparición de problemas fitosanitarios, principalmente la marchitez de plantas. Los productores han asociado este síntoma con Phytophthora spp. y aplican para su control fungicidas a base de metalaxyl, lo cual reduce la incidencia...

The tobacco (Nicotiana tabacum L.) seeds are very small. It cause very difficult to sowing. The tobacco seedling are easy infection by pathogens, caused by unevenness of germination. Therefore, this experiment was pelleted of tobacco seeds with different chemical fungicides and tested of pelleted seeds for seed quality and longevity storage. The experiment was conducted at Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. The tobacco seeds were pelleted with pumice 150 g. per 3 g. as filler and used hydroxylpropyl methylcellulose (HPMC) at a concentration of 4% by weight as binder. Three types of fungicides were used: metalaxyl, captan and pylaclostrobin. Each type of fungicide was used 2, 4 and 6 g.ai. After that, the pelleted seeds...
