Abstract. Kavosi MR, Faridi F, Hajizadeh G. 2012. Effects of foliar application herbicides to control semi-parasitic plant Arceuthobium oxycedri. Nusantara Bioscience 4: 76-80. Epiphytes are plants growing on the stem and branches of other growing plants. Dwarf mistletoe (Arceuthobium oxycedri) is one of the important macro epiphytes or semi-parasitic plant, is able to damage Junipers and provide favorable conditions for bother damaging factors such as pest, disease, rodent animals and vulnerability to unfavorable climate conditions. In this study used herbicides in three concentrations (1.35, 1.93, 2.7 g of Roundup, 0.675, 0.964, 1.35 g of Basagran, and 0.9, 1.28, 1.8 g of Gramoxone in1000 mL water) and three replications to examine the impact of each herbicide on A. oxycedri at Junipers forests in areas located at the East Gorgan state region, North of Iran. The results from Basagran on 95.55% dwarf mistletoe indicated that the plant was dried completely up. Roundup dried 61.67% of dwarf mistletoe. Gramoxone cause the lowest percent of dryness (23.89%). By analyzing results about the impact of herbicides on percentage of measuring dryness, there is difference in level significant 1% between of herbicides. The impact of each herbicide on A. oxycedri showed that concentration-3 has more impact increasing dwarf mistletoe dryness but with concentration-2 it has less difference. Ultimately concentration-2 Basagran can be used to reduce costs in order control dwarf mistletoe.

 

Key words: herbicide, Arceuthobium oxycedri, epiphyte, dwarf mistletoe, semi-parasitic plant

 

Abstrak. Kavosi MR, Faridi M, Hajizadeh G. 2012. Pengaruh aplikasi herbisida daun untuk memgendalikan tumbuhan semi parasit Arceuthobium oxycedri. Bioscience Nusantara 4: 76-80. Epifit adalah tumbuhan yang hidup pada batang dan cabang tumbuhan lain. Benalu kerdil (Arceuthobium oxycedri) merupakan salah satu tumbuhan makro-epifit penting atau semi parasit, yang dapat merusak tanaman juniper dan mendorong hadirnya faktor perusak seperti hama, penyakit, hewan pengerat dan keretanan terhadap kondisi iklim yang tidak menguntungkan. Dalam penelitian ini, herbisida dibuat dalam tiga konsentrasi (1,35, 1,93, 2.7 g Round-up, 0,675, 0,964, 1.35 g Basagran, dan 0,9, 1,28, 1.8 g Gromoxone dalam 1000 mL air) dan tiga ulangan untuk mengetahui dampak masing-masing herbisida pada A. oxycedri di hutan juniper Gurgan Timur, Iran. Aplikasi Bazargaran pada benalu kerdil menghasilkan kematian sebesar 95,55% menunjukkan bahwa tumbuhan tersebut mengering seluruhnya. Round-up menyebabkan mengeringnya 61,67% dari benalu kerdil. Gromoxone menghasilkan persentasre pengeringan terendah (23,89%). Dengan menganalisis dampak herbisida terhadap persentase pengeringan, terdapat perbedaan pada taraf signifikansi 1% di antara herbisida. Dampak masing-masing herbisida pada A. oxycedri menunjukkan bahwa konsentrasi 3 lebih berdampak pada pengeringan benalu kerdil, namun hanya berbeda sedikit dengan konsentrasi 2. Pada akhirnya konsentrasi 2, Basagran dapat dipilih untuk mengurangi biaya dalam pengendalian benalu kerdil.
