Uji Beberapa Ekstrak Daun Tanaman Untuk Mengendalikan Jamur Tular Benih Kacang Tanah (Arachis Hypogeae L.) Dan Pengaruhnya Terhadap Daya Kecambah Benih
Seedborne diseases on peanut seeds can be controlled by using plant leaf
extracts which applied by seed treatment. The plants leaf used, such as: sambiloto
leaves extract, bay leaves extract, basil leaves extract and guava leaves extract. The
aim of this research is to study the effect of application several plants leaf extract and
obtain the best extract to control seedborne fungal pathogens on peanut seeds and its
effect to germination of peanut seeds. The research has been conducted at the
Laboratory of Plant Disease and Greenhouse Experimental Field at Faculty of
Agriculture, Riau University, Pekanbaru. This research has been conducted
experimentally by using a complete random design (CRD) consisting of 5 treatments,
namely: without application of plants leaf extract (E0), sambiloto leaves extract 30%
(E1), bay leaves extract 30% (E2), basil leaves extract 30% (E3) and guava leaves
extract 30% (E4). The data obtained were statistically analyzed with analysis of
variance and to compare the mean of treatments, Tukey’s test at level 5% was
applied. The result obtained 5 isolate seedborne fungus on peanut seeds. The results
showed that application of basil leaves extract was able to inhibit the growth of
Rhizoctonia sp. (30.25%), Macrophomina sp. (41,00%), Rhizopus sp. (20,25%) and
Aspergillus sp. (1) (15,00%), the extract of bay leaves have a higher inhibition of
Aspergillus sp. (2) (31.25%). The application of bay leaves extract resulted in a better
germination rate of (93.00%). The application of the four plants leaf extract were not
able to affect the total normal germination seeds, seedling height and decreasing the
total of symptomatic disease seedlings.
