Sari. Pengendalian gulma dengan menggunakan herbisida tunggal bila dilakukan terus menerus akan menimbulkan gulma resisten. Pencampuran herbisida perlu dilakukan untuk menanggulanginya. Campuran herbisida dengan dua atau lebih jenis bahan aktif dapat bersifat sinergis, aditif, atau antagonis. Tujuan dari penelitian adalah untuk mengetahui sifat campuran herbisida Atrazin 500 g/L + Mesutrion 50 g/L terhadap beberapa jenis gulma dominan pada tanaman jagung. Percobaan dilaksanakan pada bulan November 2018 sampai Januari 2019, di Rumah Kaca Fakultas Pertanian Unpad,  Jatinangor. Perlakuan terdiri dari tiga jenis herbisida dengan enam tingkat dosis, yaitu herbisida tunggal Atrazin (1200, 600, 300, 150, 75, 0 g/ha), Mesotrion (120, 60, 30, 15, 7,5, 0 g/ha) dan campuran herbisida dari Atrazin 500g/L dan Mesotrion 50 g/L (1056, 528, 264, 132, 66, 0 g/ha) dengan empat ulangan. Gulma target adalah gulma A. conyzoides, S. nodiflora, C. rotundus, dan E. indica. Analisis data menggunakan analisis regresi linear dan metode MSM untuk menentukan LD50 perlakuan dan LD50 harapan. Hasil percobaan menunjukkan bahwa pencampuran herbisida berbahan aktif Atrazin 500 g/L dan Mesotrion 50 g/L memiliki nilai LD50 perlakuan (85,11 g/ha) lebih kecil dari nilai LD50 harapan (86,9 g/ha) sehingga dapat disimpulkan sifat campuran herbisida tersebut bersifat sinergis.Kata kunci : Atrazin, Mesotrion, Herbisida campuran, Gulma dominan tanaman jagung  Abstract. Weed control by using a single herbicide continuously will cause weeds resistant, so it is necessary to mix herbicides. Mixture of herbicide with two or more types of active ingredient can be synergistic, additive, or antagonistic. The objective of this research is to know the effect of herbicide mixture of Atrazin 500 g/L and Mesotrion 50 g/L to several types of dominant weeds. The research was conducted from November 2018 until January 2019, at the Green house of Faculty of Agriculture, Padjadjaran University, Jatinangor. The treatment was consisted of three types of herbicide with six level of doses. There were herbicide Atrazine 500 g/L (1200, 600, 300, 150, 75,0 g /ha), Mesotrion 50 g/L (120, 60, 30, 15, 7.5, 0 g/ha) and herbicide mixtures Atrazine 500 g/L and Mesotrion 50 g/L (1056, 528, 264, 132, 66, 0 g/ha) with four replications. The target weeds were A. conyzoides, S. nodiflora, C. rotundus and E. indica. Data was analyzed by linear regression and MSM method to determine the value of LD50 treatment and  LD50 expectation. The results showed that herbicides mixture of Atrazine 500 g/L and Mesotrion 50 g/L had a value of LD50 treatment 85.11 g/ha which is smaller than the value of LD50 expectation (86.9 g/ha), this  indicating that the herbicide mixtures was synergistic.Keywords: Atrazine, Mesotrion, Mixed herbicides, dominant weeds of corn

Forage Yields

Forage corn (Zea mays L.) was grown successfully in Prince Edward Island by no-till planting the corn into standing cereal stubble 15–20 cm tall using a Buffalo no-till seeder. Planting with the slot-type shoe in a preliminary experiment in 1978 gave better forage yields than planting with a slice-type shoe mainly because of better plant population achieved. Subsequent experiments in 1979–1981 using the slot-type shoe to no-till plant corn in cereal stubble gave good forage yields when adequate weed control was provided with herbicide treatment. Best control of quackgrass (Agropyron repens L. Beauv.) and dandelion (Taraxacum officinale Weber) and crop yields was achieved with glyphosate + atrazine (1.5 + 2.5 kg a.i./ha) or amitrole + atrazine (3.4 + 2.5 kg a.i./ha) applied preemergence after seeding corn and before corn emergence. Control of quack grass and dandelion with glyphosate or amitrole used alone ranged from 71–80%, but paraquat alone did not provide any weed control. Addition of atrazine to paraquat, glyphosate, or amitrole gave improved control of quackgrass and dandelion and higher forage corn yields. Addition of 2.5 kg a.i./ha atrazine gave better results than use of 1.0 kg a.i./ha of atrazine.Key words: Forage corn, no-till seeding, glyphosate, atrazine, aminotriazole, paraquat

Annual weed control may be improved when AMS is added to below-label glyphosate doses in glyphosate-tolerant maize (Zea mays L.)

EPTC and the antidotes, R25788 (N, N-diallyldichloroacetamide) and R29148 (2, 2, 5-trimethyl-3-dichloroacetyl oxazolidine) were applied to field plots of corn (Zea mays L.) in the fall or spring from the fall of 1975 to the spring of 1978. Soil samples were taken from selected treatments in the fall of 1977 and spring of 1978. Residues of EPTC, R25788, and R29148 were measured by gas liquid chromatography. Much better weed control and higher corn yields were obtained with spring applications than with fall applications. EPTC at the highest rate of 13.4 kg/ha, without the antidotes, did not injure corn. Over 95% of the EPTC present in the soil on 24 Oct. 1977 had disappeared by 30 May 1978. Levels of EPTC on 30 May 1978 were appreciably higher following spring application. Neither R25788 nor R29148 disappeared faster than EPTC from the surface layer of soil.Key words: EPTC, R25788, R29148, soil residues, corn
