Uji Efektifitas Herbisida Atrazin, Mesotrion, dan Campuran Atrazin+Mesotrion terhadap Beberapa Jenis Gulma
Abstract: The aimed of this
research was to know the effectiveness of mixing herbicides with active
ingredient atrazin and mesotrion in controlling weeds and know the mixture
characteristic. This research conducted
in the plastic garden house private in Natar, South Lampung and in the Weeds
laboratory of Agriculture faculty, Lampung University from June until July
2013. This Research arranged in a Randomized Completely Design (RCD). Treatment consists of three types of
herbicides with six level of dosage active ingredient, namely of single
herbicides is atrazin 500 g l-1 (0, 76, 152, 304, 608, and 1.215 ha g-1),
mesotrion 50 g l-1 (0, 11, 22, 43, 86, and 172 g ha-1), and mixed herbicides
from atrazin 500 g l-1 + mesotrion 50 g l-1 (0, 28, 56, 112, 225, and 450 g
ha-1). The target weed were a type of
broadleaves (Asystasia gangetica), a type of grasses (Paspalum conjugatum), and
a type of sedges (Cyperus kyllingia).Homogenity tested using Bartlet and aditivity
tested using Tukey, data analyzed by Analisis of Variance and different median
values tested with Least Significant Difference (LSD) level 5%. Results showed
that an active ingredient mixture of atrazin 500 g L-1 + mesotrion 50 g L-1 has
LD50 expectation value of 51,48 g ha-1 and LD50 treatment of 257,48 g ha-1 with
the co-toxicity value was 0.2 (co-toxicity < 1) until mixture was
antagonist.
