Abstract

ABSTRACT Pseudomonas solanacearum is a bacterium that causes wilt disease in tomato, peppers, tobacco, potatoes and Solanaceae plants in general. The bacteria attacks their hosts in nearly all phases of development. Young plants are usually more vulnerable and the bacteria  tends to grow faster. The use of synthetic pesticides for controlling the disease could cause many negative impact on human and environment, Hence,  it is necessary to find an environmentally friendly pesticides for controlling the disease. Urang aring (Eclipta alba L. Hask.) contains  bioactive compounds that  potential to be used as botanical pesticides. This research was conducted to evaluate the effect of ethanol extracts  of urang aring (Eclipta alba L. Hask.) to inhibit the growth of Pseudomonas solanacearum. Bioassay was done by deluting extracts to make concentration 1%, 2%, 3%, 4% (w/v). The result showed that ethanol extracts inhibited the growth of P. solanacearum starting at concentration 1% with inhibition zone diameter 10,7 mm. At level  4% concentration (inhibition zone diameter 17.59 mm) were not significant difference with agrmicyn  0.03%, a synthetical bactericidal with inhibition zone diameter 18,31 cm. The results of this study revealed that urang aring was potential as botanical pesticide. Keywords: Urang Aring, Eclipta alba, Pseudomonas solanacearum

Abstract

ABSTRACT The purpose of this research was to study the effect of the concentration of growth inhibitor Paclobutrazol (Pbz) against the high growth of clove seedlings (Syzygium aromaticum (L.) Merryl & Perry) and get Pbz concentrations that can produce seed cloves in a relatively short (dwarf). The results showed that spraying Paclobutrazol (Pbz) with 25-100 ppm affect height growth of clove seedlings. Pbz the higher concentration applications, the shorter the length of apical segments produced shoots. In other words, the higher the concentration Pbz, the higher the emphasis on high growth of clove seedlings. Pbz emphasis on high growth of clove seedlings varied from the lowest, ie. 3.79% (25 ppm) up to the highest, ie 69.85% (100 ppm). Based on the comparison of height increment of plants sprayed with Paclobutrazol, the dose applications can be used to get the seed cloves that dwarf is a concentration of 50 to 100 ppm.
