Effectiveness of Weed Solut-Ion as herbicide adjuvant to control weeds in oil palm plantations

Abstract

The use of herbicides is an effective and efficient way to control weeds in oil palm plantations. However, overdoses application of herbicides is hazardous to the environment. Therefore, it is necessary to find a method to reduce hazardous effects caused by excessive doses of herbicides. Adjuvant herbicides are a well-known compound that could enhance herbicide performance. Weed Solut-ion (WS) contains 2-sodium amine allegedly reduces herbicide dosage at the same time enhances its performance. The objective of this research was to determine the response application of Weed Solution as herbicide adjuvant for paraquat and fluroxypyr by reducing the dosage so that the application can be more efficient and environmentally friendly. The experiment was conducted in the Socfin Group Plantation using a completely block design with two treatments (control; paraquat:WS = 50:50; fluroxypyr:WS = 50:50). The results showed that weeds control and regrowth rate from treatment (paraquat:WS = 50:50) were not significantly different from the control. The cost efficiency resulted from the treatment was 25.56%. The dose treatment of fluroxypyr combined with WS (doses 50:50) was not significantly different from control, and the cost efficiency was 36.43%.
