| Sumario: | This research was conducted in the months of June and August 2013, on the premises of Mr. Eduardo Zambrano located in the parish of La Guayas Canton The Empalme, with the adjective to determine the selectivity and better weed control of the treatments , as well as an economic analysis of them based on their selectivity and efficiency . The experimental design was randomized complete block called ( RCBD ) with five treatments and five replications. For statistical analysis to test TUKEY ≥ 5% probability was performed. The treatments and dose active ingredient per hectare ( 200L. ) were as follows : T1 (Amine 2,4-D) + ( picloram + 2,4- D Amine ) T2 ( + AminaAminopyralid ) + (picloram + fluroxypyr ) + (metsulfuron methyl) T3 ( AminaAminopyralid + ) + (picloram + fluroxypyr ) + (metsulfuron methyl) T4 ( + AminaAminopyralid ) + (picloram , fluroxypyr ) T5 ( Picloram - Fluroxypyr ) + (metsulfuron methyl) . The trial was aimed to control broom (Sidarhombifolia ) for their further proliferation in the study area . Of the variables studied cultivation can be noted that none of the treatments caused signs of toxicity nor affected the normal crop growth resulting fully selective. In regards to the number of dead plants observed a broom signficancia between treatments in this variable to finish the investigation in relation to the control showing the highest average in the control of broom was Treatment 4 . The most economical treatment was 2,4- D Amine T2 - 180 gr Aminopyralid 9 gr ( 1806.2 cc / Ha) + Picloram 80g . - Fluoroxypyr 80g ( 190.2 cc / Ha) + methyl Metsulfuron 50% ( 3.4 g ) / 200l./Ha ). But to broaden the spectrum of control is recommended also try the T3 treatment(Amina 2,4-D- Aminopyralid 1803,4 cc + Picloram – Fluoroxipir 189,8 cc + Metsulfurónmetil 6,8gr /200 lts/Ha.). The most economical / efficient treatment according to the economic analysis was the T3 costing formula 20, $ 49 and a cost / day of 0.47 cents. |
