Fosberg)}, volume={40}, url={https://jurnal.ipb.ac.id/index.php/jurnalagronomi/article/view/14939}, DOI={10.24831/jai.v40i1.14939}, abstractNote={<p>Sengon (Albizia falcataria L. Fosberg) forest plantations of community in Wonosobo District, Central Java were<br />attacked by gall rust disease. The objective of this research was to investigate the role of insects as a vector of gall rust<br />disease. The attack intensity was measured in the different ages of tree stand (1, 2, 3, 4, and 6 year old) with randomized<br />complete block design (RCBD) consisting of 3 blocks, 3 replications, and 3 sampling plots. The role of insect as a vector<br />was tested using two different approaches: observation on the spores in the adult insect integument and artificial investation<br />of insect containing spores on the healthy seedlings. The result of this research showed that the one year old of sengon had<br />highest disease intensity (95.5%) and lowest disease incidence (56.96%). The identification showed that the insect belongs<br />to Lepidoptera (Family Heliozelidae) completing the metamorphosis in the gall. Spores were found in the integument of<br />Lepidoptera (Family Heliozelidae) at the average of 2.8 x 104 spore μL-1 insect-1. Artificial innoculation on healthy seedling<br />did not show the infection symptoms by Uromycladium tepperianum until 5 weeks after innoculation.</p&gt;}, number={1}, journal={Jurnal Agronomi Indonesia (Indonesian Journal of Agronomy)}, author={Triyogo, Ananto}, year={2017}, month={Jan.} }
