IDENTIFIKASI Fusarium PENYEBAB PENYAKIT LAYU PADA TANAMAN CABAI (Capsicum annuum L.) DAN ENGENDALIANNYA DENGAN MIKORIZA VESIKULA ARBUSKULA (MVA)
Red pepper (Capsicum annuum L.) i s fruit vegetables which is consumed 
daily. Chili needed from year to year but crop yield has decreased. This is caused 
by Fusarium wilt disease. Disease control is commonly used a fungicide but it
may lead harmful residues to the environment. One alternative controlling that 
could be done is by utilizing vesicular arbuscular mycorrhizal (VAM) fungi. The 
purpose of this study was to identify the types of Fusarium wilt disease that attack
pepper, select the Fusarium which had the highest effectively against Fusarium
wilt disease and determine the effect of VAM inoculum to growth and 
suppression of Fusarium wilt disease intensity in pepper. Method of this research 
included isolation and identification of F. oxysporum causing Fusarium wilt of 
pepper plant roots, based on macroscopic and microscopic characters, surface 
color, presence or absence of color pigment, hyphae, macroconidia, microconidia
and false heads. Then F. oxysporum was tested in vitro and in vivo by inoculating 
VAM, inoculation of F. oxysporum was done 6 weeks after VAM inoculum. 
Observation of the growth parameters included the number of leaves, plant height, 
root length, shoot fresh weight, root fresh weight, shoot dry weight, root dry 
weight, root disease index and the percentage of infected VAM. The results 
showed that treatment of VAM significantly affect the growth parameters but did
not affect the presence of F. oxysporum. Fusarium wilt disease attacked in pepper 
were F. oxysporum and F. solani. with the highest intensity was the F. oxysporum. 
VAM inoculum affected plant growth and didnâ��t affect the intensity of wilt 
disease suppression.
