etil pirazosulfuron 20%, fitotoksisitas, gulma, padi sawah,Abstract
Gulma merupakan salah satu kendala utama dalam produksi padi sawah. Gulma menurunkan kualitas dan kuantitas hasil tanaman padi sawah sehingga gulma harus dikendalikan. Penelitian ini bertujuan untuk mengetahui efektivitas herbisida berbahan aktif etil pirazosulfuron 20% untuk mengendalikan gulma padi sawah. Percobaan dilaksanakan di SPLPP Fakultas Pertanian Universitas Padjadjaran Ciparay, Kecamatan Baleendah, Kabupaten Bandung, Jawa Barat pada bulan November 2018 sampai Maret 2019. Percobaan menggunakan Rancangan Acak Kelompok satu faktor dengan tujuh perlakuan dan empat ulangan. Percobaan terdiri atas lima perlakuan herbisida berbahan aktif etil pirazosulfuron 20% dengsan dosis 60; 80; 100; dan 120 g ha-1 , pembanding berupa herbisida formulasi lama dengan bahan aktif yang sama (80 g ha-1 ), pengendalian gulma manual dan tanpa pengendalian gulma. Hasil menunjukkan aplikasi herbisida berbahan aktif etil pirazosulfuron 20% dengan dosis 80 g ha-1 mampu menekan pertumbuhan gulmagulma Ludwigia octovalis, Marsilea crenata, Monochoria vaginali, Sphenoclea zeylanica, gulma teki Cyperus iria, gulma spesies lain dan gulma total, serta tidak menimbulkan fitotoksisitas terhadap tanaman padi.Downloads
