FUNGICIDES FOR THE RICE GLUMES SPOTS DISEASES CONTROL

[摘要] A field experiment to evaluate fungicide efficiency in glumes disease control of rice (Oryza sativa L.) was conducted. The randomized complete-block design with four replications was utilized. The fungicides utilized were Propiconazole, Pyroquilon, Mancozeb and IBP, with one or two sprayings. At maturation stage it was harvested a sampling of panicles to pathology analises of glumes at laboratory. The methods utilized were seedling test and blotter test. Because the complex cause of glume disease, it was not possible to detect efficient fungicide effect to control one, over yield/ha and grain yield.
