Daftar Isi:
- Cabbage has many types. One that is quite serious is clubroot disease caused by Plasmodiphora brassicae Wor. which causes swelling of the roots. The control of pests and diseases of upland vegetables has been using pesticides, both insecticides and fungicides. Utilization of materials derived from plant growth or known as vegetable pesticides can be used as an alternative agricultural technology development (Pirngadi, 2014). Vegetable pesticides used are turmeric rhizome extract. In addition to using plant-based pesticides to control pathogenic clubroot, organic materials are also used, namely husk charcoal. This study aims to determine the effectiveness of plant-based pesticides, rhizome extracts and turmeric tubers and the use of husk charcoal in controlling the pathogenic Plasmodiophora brassicae Wor which causes clubroot disease in cabbage plants. This research will be conducted in a screenhouse located in Graha Dewata Housing Block JJ4 No.10, Dau District, Malang Regency. The study was conducted for four months starting in November 2018 until February 2019. Using a simple randomized block design (RBD) with 9 treatments repeated three times so that there are 27 experimental units. The effect of the treatment was analyzed by variance (ANOVA). If there is a real difference between treatments, then a further test is conducted with a real honest difference test (BNJ) at a 5% significance level. The results of turmeric and husk charcoal separately test the turmeric tuber (P3) effect on root length and root wet weight. While the combination of turmeric and rhizome extract from husk (P4) affects the number of leaves, plant height, attack intensity, and crop diameter. The combination of turmeric tubers and husk charcoal (P5) influences the acquisition of greater yield on the variable weight of the head and root dry weight. Thus both turmeric tubers and turmeric rhizome extracts are effective in controlling clubroot pathogens in cabbage plants. And husk charcoal can inhibit the emergence of clubroot pathogens in cabbage plants when combined with turmeric or rhizome extracts of turmeric. This is evidenced by the low intensity of attacks on the combination treatment of husk charcoal with turmeric rhizome extract.
