Uji Ketahanan Tanaman Tomat Terhadap Serangan Xanthomonas Campestris Pv. Vesicatoria Dengan Beberapa Pengenceran Bacillus Subtilis
ABSTRACT
The aim of this study to know the effect of several dilutions of Bacillus subtilis and to obtain a dilution capable of inducing tomatoes from attack by Xanthomonas campestris pv. vesicatoria. This study was conducted experimentally using a completely randomized design (CRD) with 4 treatments and 4 replications. The treatment used was the dilution of Bacillus subtilis which consisted of B1 = dilution of Bacillus subtilis 10-6, B2 = dilution of Bacillus subtilis 10-7, B3 = dilution of Bacillus subtilis 10-8, B4 = dilution of Bacillus subtilis 10-9. The parameters observed were the total population of Bacillus subtilis in growth medium, the concentration of salicylic acid content, disease intensity, plant height, stem diameter and weight of fruit. The results showed that the dilution of Bacillus subtilis was able to induce tomato plant resistance to Xanthomonas campestris pv. vesicatoria and gave significantly different results on total population on soil medium, concentration of salicylic acid content, disease intensity, plant height, steam diameter and weight of fruit.
Keywords: Xanthomonas campestris pv. vesicatoria, Bacillus subtilis, tomato, dilution.
