This research was conducted in Laboratory of Pest and Plant Disease and C Green House Faculty of Agriculture Universitas Sebelas Maret Surakarta from April-July 2018. The stages of this study include the multiplication of S. litura test larvae, preparation of botanical insecticides from tobacco dust waste, mortality test, antifeedant test and phytotoxicity test. This study used a completely randomized design with 6 treatments and 4 replications. The results showed that tobacco dust waste was able to increase the mortality of S. litura larvae, but with a slower effect compared to the treatment of profenofos. Feeding barriers are not seen in the test larvae. The phytotoxicity test shows that tobacco dust waste was not toxic to plants. Based on probit analysis, the concentration of tobacco dust waste which was capable of killing 50% of the population of S. litura was equal to 53.10 gL-1.","PeriodicalId":222142,"journal":{"name":"Agrosains: Jurnal Penelitian Agronomi","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130005067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research used Randomized Block Design with 6 treatment and 4 replications. Media types were: P1 (rockwool), P2 (raw husk), P3 (charcoal husk), P4 (bricks), P5 (cocopeat) and P6 (zeolite). Parameters considered include plants, number of leaves, number of productive branches, stem diameter and number of flowers. Data were analyzed using Variant Analysis (ANOVA) followed by Honestly Significant Difference Test with 95% confidence interval adn correlation test. This research showed that zeolite growing media was able to support flowering of petunia plants with the highest average number of flowers (6.17) followed by brick planting media (5.38).
