The Fusarium isolates were identified and then tested for pathogenicity levels and the effect of the hormones GA3 and IAA on shallot symptoms. Molecular identification using NF2 and NF4 successfully identified one isolate of Fusarium oxysporum, three isolates of F. acutatum, and three isolates of F. solani. Each of these species produces different symptoms. Pathogenicity test showed that all isolates had disease incidence reaching 100%, except isolates of F. solani1 causing wilt and F. solani3 causing twisted have the lower disease incidence were 77.8% and 77.7%, respectively. The investigation caused twisted shallot related to different symptoms was tested using the Thin Layer Chromatography (TLC) method. The result indicates that all isolates did not find IAA hormone. In contrast, the hormone GA3 was found in F. solani2 and F. solani3 isolates, caused bulb rot and twisted disease, respectively. Detection of IAA, GA3, and other hormones in shallot plants showed different symptoms should be studied further.","PeriodicalId":427271,"journal":{"name":"JPT : JURNAL PROTEKSI TANAMAN (JOURNAL OF PLANT PROTECTION)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128181884","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 research was carried out in Organic Chemistry Laboratory STIFARM Padang, in Tabek Patah Tanah Datar area West Sumatra, and in the Pest Disease Observation and Development of Biological Agents Laboratory, Bukittinggi, West Sumatra, from June to August 2020. The treatment was in the form of different doses of basil leaf oil, which was 0,5 ml per trap, 1.0 ml per trap, 1.5 ml per trap, 2.0 ml per trap, and 2.5 ml per trap. The experiment used a completely randomized design with five treatments and three replications. This study found two species of fruit flies around chili plants, namely Bactrocera papayae and Bactrocera carambolae, which were dominated by male B. papayae. The traps containing 1.5 ml of basil leaf oil attracted the most fruit flies. Temperature and humidity significantly affect the abundance of individual fruit flies.","PeriodicalId":427271,"journal":{"name":"JPT : JURNAL PROTEKSI TANAMAN (JOURNAL OF PLANT PROTECTION)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130938040","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 study was conducted using a survey method with purposive sampling conducted from July to September 2019 with the criteria of observing plants two weeks after planting and determining the sample diagonally. The results showed that cabbage plants in Mount Marapi, Agam Regency, were attacked by two snails, namely Bradybaena similaris and Parmarion sp. The population of B. similaris was higher than that of Parmarion sp. Mustard plants are most at risk of being attacked by snails, with the highest percentage and intensity of attack even though the damage category is classified as moderate.
