Efecto de la interacción de herbicidas más coadyuvantes aplicados sobre las malezas en el cultivo de arroz

Abstract:

The present investigation work was carried out with the objective of evaluating the effects of helping on the application of herbicides in the cultivation of rice, variety INIAP 15 in the area of Babahoyo; to identify the most effective treatment in the control of overgrowths and to analyze the results economically. It was made in the dry time of the 2011, in the lands of the property of the Ab. Ausberto Hill, located in the km 6 ½ via Babahoyo - Montalvo, sector "The Paradise", canton Babahoyo, county of The Ríos. Certified seed of the variety INIAP was used 15. The treatments herbicides were evaluated with the help of Pyribenzoxim (Pyanchor) + Metsulfuron metil (Ally); Penoxulam (Flare) + Pyrazosulfuron ethyl (Checker); Quinclorac (Facet SC) + 2,4 D amina (720); Propanil (500) + 2,4 D amina (720); Pyrazosulfuron ethyl (Checker) + 2,4 D amina (720) and Cihalofop-butilo (Clincher) + Metsulfuron metil (Ally), in several dose and I eat subtratamientos they were used helping as you Indicate yourself, Mezclafix and Surfare. He/she was carried out the experimental design of divided Parcels, with six treatments (herbicides), three subtratamientos (helping) and three repetitions. The comparisons of the stockings were made with the test of Duncan. The evaluated data were: toxicity index, control of overgrowths, plant height, macollos for square meter, days to floración, days to maturation, panículas for square meter, panícula longitude, grains for panícula, yield of the cultivation and economic analysis.
