Abstract
Weeds are plants whose existence is undesirable
because they can harm productive plants grown by humans such as rice by
competing directly for nutrients, light, water and space to grow. Weed control
can be done chemically using herbicides which are considered more effective.
One type of herbicide that can be used to control weeds in lowland rice
cultivation is a herbicide with the active ingredient ethyl pyrazosulfuron.
This study aims to determine the effectiveness of herbicides with the active
ingredient 10% ethyl pyrazosulfuron in controlling weeds, and their effect on
the growth and yield components of lowland rice. This research was conducted at
the SPLPP Faculty of Agriculture, Padjadjaran University, Ciparay, Baleendah
District, Bandung Regency, West Java from June to September 2022. The study was
arranged in a randomized block design with 7 treatments and 4 replications. The
treatment consisted of a dose of 10% ethyl pyrazosulfuron herbicide with a
level of 150; 225; 300; 375; 450 g/ha, manual and control weeding. The results
showed that 10% ethyl pyrazosulfuron herbicide at a dose of 150 – 300 g/ha was
effective in controlling weeds in lowland rice cultivation, namely weeds Sphenoclea
zeylanica, Ludwigia octovalvis, Cyperus difformis, Leptochloa
chinensis, and total weeds up to 6 weeks without causing
phytotoxicity in rice plants. The herbicide ethyl pyrazosulfuron 10% had a good
effect on the yield of rice plants.
