Resumen
En la Estación Experimental Fabio Baudrit, Subestación de Fraijanes, se escogieron áboles de melocotón de las variedades Big Boston y Hall’s Yellow injertados sobre durazno criollo para evaluar el efecto de tratamientos con ácido naftalenoacético al 1% y 1,5%; glifosato 1,5%; así como el corte manual con tijera de podar, para reducir el número y tamaño de los brotes basales. Dos meses después de aplicados los tratamientos, se contaron y midieron los brotes presentes y se encontró que el tratamientos con ácido naftalenoacético al 1% fue el más efiiente y económico. El glifosato tuvo efecto tóxico en las plantas y el corte con tijera no controló el rebote en forma efectiva. No se observaron diferencias entre las variedades.
At the Fraijanes Sub-station of the Fabio Baudrit Experiment Station, in the upper Central Valley of Costa Rica, peach trees of the big Boston and Hall’s Yellow varieties, grafted on criollo (local) peach rootstock, were used to evaluate the reduction of basal (stock) sprout size and number by the following treatments: naphthaleneacetic acid, 1% and 1,5%; gliphosate, 1,5% manual cutting with shears. Two months after treatment application, all basal sprouts present were counted and measured. Naphthaleneacetic acid at 1% was the mostefficient and economical in reducing sprout number and size. Gliphosate had a toxic effect on tree tops, and shear cutting failed to control sprouting effectively. No differences between both varieties were observed.
