Hyphae color that comes out of the insect's body depends on the type of entomopathogenic fungus that attacks it. The purpose of this research is to explore, isolate and identify entomopathogenic fungi that attack insect pests. Samples of dead insects were taken from vegetable crops in the highlands of Pagaralam City and the lowlands of Ogan Komering Ilir Regency. In addition, exploration is also carried out using insect bait methods. This method is carried out on soils taken from the highlands of the fencealam area and Pekanbaru area. Based on the results of entomopathogenic expolation in vegetable plants that infect insects in the field there are 2 types of fungi that attack the insect. Two types of entomapatogenic fungi were found to have characteristics, namely the first hyphal color is rather green which covers the entire body of the insect and the second is white hyphae. The fungus that attacks the insect, then isolated to the GYA media found two entomopathogenic fungi namely, Metarhizium sp. and Beauveria bassiana. Meanwhile, through insect bait using soil T. molitor larvae, one species of entomopathogenic fungus was found, namely Metarhizium sp. The most infected T. molitor larvae in the soil of origin of Pekanbaru in the 2nd and 4th weeks, namely, 21.90 and 29.33 tails. \u0000  \u0000. \u0000Keywords: Entomopathogenic Fungus, Insect Pest and Tenibrio molitor \u0000 ","PeriodicalId":150469,"journal":{"name":"Jurnal Proteksi Tanaman Tropis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126246694","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}

This study used a randomized block design with 7 treatments, namely A (Kontrol), B (Oksifluorfen, peleton), C (Etil pirazosulfuron, peleton), D (Sulfentrazon, peleton), E (Oksifluorfen, kanton tavi), F (Etil pirazosulfuron, kanton tavi), G (Sulfentrazon, kanton tavi). Each treatment was repeated 4 times. The data were analyzed used analysis of variance (ANOVA), further testing used the DMRT test with a 5 % level. The results showed that the application of herbicides made from sulfentrazone, ethyl pirazosulfuron, oxifluorfen in peleton varieties and kanton tavi can suppress weed growth in the research area. The best weed control results were shown by herbicide treatment with sulfentrazone as active ingredient in the kanton tavi variant. The best long bean production results were shown by herbicide treatment with sulfentrazone in peleton varieties. The application of herbicides with active oxifluorfen made no symptoms of phytotoxicity, but decreased the yield of kanton tavi varieties and peleton varieties.","PeriodicalId":150469,"journal":{"name":"Jurnal Proteksi Tanaman Tropis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132003282","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}

Is one type of rhizome plant commonly used as a medicinal plant or spice. The rhizome is aromatic and has a distinctive odor used by the community to be used as spices, cooking ingredients and medicinal sources. So far the results of ginger production have not been able to meet people's consumption needs due to a decrease in ginger production at the main ginger development center (West Java). One of the main constraints of ginger cultivation is the attack of bacterial wilt disease caused by the bacterium R. solanacearum. One effort that can be done in tackling bacterial wilt in ginger plants is by using clones that are resistant to bacterial wilt disease of R. solanacearum. The experimental design was carried out using factorial Completely Randomized Design, using ginger clones and the application of R. solanacearum bacteria. This design consists of 6 treatments and 4 replications. Each replication unit consists of 4 plants, so the total number of plants used is 96 plants. The experimental results were analyzed using regression correlation analysis on the parameters of disease progression, while on plant growth parameters using variance analysis and if there were significant differences then continued with Duncan Multiple Range Test (DMRT) with a confidence level of 95%. The results showed red ginger clones including rather resistant criteria with a severity value of 25% while ginger empirical clones and elephant ginger clones were critically vulnerable with 75% severity values and 85.42%. Red ginger clones are more responsive to the infection of R. solanacearum bacteria so that the highest phenol content increases compared to other clones of 0.297 mg/ml, the phenol compounds that play a role in increasing plant resistance. In the variable growth of ginger emprit clone plants have a higher plant height and number of leaves compared to other clones, namely 43.83 cm and 15.44.","PeriodicalId":150469,"journal":{"name":"Jurnal Proteksi Tanaman Tropis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126049253","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 presence of herbivorous Arthropods in the swampland rice ecosystem can be suppressed by the presence of useful Arthropod populations such as predators, parasitoids, and pollinators. Related to this, a study was conducted to find out the diversity of Arthropods found in swampy rice plantations. The study began with a land survey, then the determination and marking of observation plots on the map and matching these locations using GPS (Global Positioning System). Observations were made on plots that were made based on the extent of rice plants that were still in one stretch and the same irrigation flow. Each plot was observed ten times at 7-day intervals from rice plants aged 14 days after 77 days after planting. Arthropod sampling using sweep net method. Catching arthropods are put into vials of 5 ml size and then identified up to family level, and the diversity, evenness, and wealth index of the species is calculated. The results of research on swamp rice plants contained 37 families. Ten families act as herbivorous Arthropods, 15 families as predators, six families as parasitoids, one family as pollinators, and five families as detritivores. The highest diversity index in plot 1 was 2.95, while the lowest in plot 2 was 2.70, with the medium category for all observation plots. The magnitude of the diversity index is due to the dominance of only a few orders, such as Orthoptera and Diptera; the highest species wealth index in plot 3 with a value of more than 4 in the high category; Evenness index of all observation plots has a value of less than 1 with uneven categories.   \u0000Keywords: arthropods, diversity, natural enemies, swamp land","PeriodicalId":150469,"journal":{"name":"Jurnal Proteksi Tanaman Tropis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130109373","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}
