- Abstract
Many of the main fungal pathogens of the rice crop are efficiently transmitted in the seeds. A study was carried out to compare the fungicide fludioxonil at the rates of 0.5, 1.0, 1.5, 2.5, 5.0 and 10.0 g ai./ 100 kg of seeds with the standard treatment of benomyl + TMTD (150 + 150 g ai. /100 kg) used in Cuba on the disinfection of seed of the varieties: a) non commercial rice seed; b) Reforma 28; c) Reforma 29 and d) J 104. For each variant of treatment, 100 g of seeds were treated in plastic bags with a final solution of 10 mL being left overnight in the bags. The seeds were incubated in a blotter test at 27 °C under two 40w fluorescent lamps during 10 days. The best effect on seed germination, fungal growth inhibition and necrosis development in hypocotyls and plumule were obtained with the rates of 5 and 10 g ai./100 kg, which showed to be superior to the standard treatment of benomyl+TMTD in use in the practice. At the rate of 5 g ai of fludioxonil, some species of the seed contaminants Aspergillus and Rhizopus were not fully inhibited. The rate of 2.5 g of fludioxonil/100 kg and lower showed a reduced efficacy. It is recommended the use of fludioxonil at the rate of 5 and 10 g of ai./100 kg of seeds as a new alternative with lower environmental impact for the rice disinfection against fungal pathogens than the standard treatment in use.
