This study aims to determine the relationship of social domographic factors with the behavior of farmers in applying pesticides to shallots in Sigi Biromaru District, Sigi Regency. This research uses quantitative methods using univariate analysis for frequency distribution and bivariate analysis (chi square) to determine the correlation between variables. Both use Statistical Product and Service Solutions (SPSS) 20.0. Determination of the location of the study was conducted purposively based on previous observations. The area is a center of shallot and horticulture plants in Sigi Regency, namely; Oloboju Village and Bulupountu Village, Sigi Biromaru District. The results of the study concluded that the use of pesticides by shallot farmers was over intensity with the reason for maximum production results. Unwise behavior of farmers in controlling pests and diseases with the high use of pesticides in the field, shows that there is no relationship between age, education, experience and Integrated Pest controlling (IPC) training with the behavior of shallot farmers in applying pesticides.

The purposes of this research the examine the effectiveness various concentrations neem leaf ekstract on the intensity of attack Liriomyza spp on shallot Lembah Palu variety . Field research was carried out in Guntarano Village, Tanantovea Subdistrict, Donggala Regency, Central Sulawesi. This research conducted from February to April 2016 .The experiment was done using Randomized Complete Block Design with three replications, consists of six treatments, i.e. P0 : control (without aplication neem leaf ekstract); P1: neem leaf ekstract 10 gr /litre; P2 : neem leaf ekstract 20 gr / litre; P3 : neem leaf ekstract 30 gr / litre; P4 : neem leaf ekstract 40 gr / litre; P5 : neem leaf ekstract 50 gr / litre. To find out the effect of threatment, the analysis of variance, and the real influence is continued with the standard ά = 0.05 BNT test. The results showed that use of seed and leaf extracts of neem plant can control Liriomyza spp attack, only 3,04 percent of attack rate and shallot Lembah Palu variety productivity is 3,02/area.

Biodiversity is an important part of the agricultural ecosystem (agroecosystem) and diversity is determined by the environment and the application of pesticides in the field. Research on the diversity of arthropods in shallot cultivation with different intensities of pesticide application aims to determine the types and populations of arthropods in shallot cultivation on land with different intensities of pesticide application. The research was conducted in the village of Soulowe, which is the center of shallot plants in Sigi Regency, with a massive and intensive application of pesticides, from December 2019 to March 2020. Sampling was carried out using absolute methods (direct observation) and relative methods (Pitffal Traf and Jaring Ayun). The results of the identification carried out in the Unisa and Untad Palu laboratories found that the diversity of arthropods in low-intensity areas of pesticide application was more than that of medium and high applications. There are 7 orders and 13 families, namely Oxyopidae, Grillotalpidae (Ordo Araneae), Scarabaeidae, Coccinellidae (Order Coleoptera), Forficuloidea (Order Dermaptera), Agromyzidae, Muscidae (Order Diptera), Formicidae, Apidae (Order of Hymenoptera), Noctuidae (Order of Hymenoptera) and Acrididae, Gryllidae andTotigonidae (Order Orthoptera). The level of diversity, evenness and family wealth as well as the abundance of arthropod individuals were higher in land with low pesticide application intensity than medium and high pesticide application.

Penelitian ini bertujuan untuk menyeleksi dan mengidentifikasi cendawan endofit dari pertanaman organik bawang merah lokal Palu. Cendawan endofit diperoleh dari lahan organik tanaman bawang merah bagian rizosfer kedalaman 1-10 cm, dengan menggunakan metode diagonal sampling, sehingga ditemukan 10 titik pengambilan sampel. Isolat cendawan yang telah dimurnikan kemudian diidentifikasi secara makroskopis dan mikroskopis. Hasil seleksi dan identifikasi isolat diperoleh 12 isolat cendawan endofit dari pertanaman organik bawang merah lokal Palu. Tiga isolat cendawan endofit yang unidentified, dan 9 isolat cendawan endopit yakni; Penicilium sp,Trichoderma mf 1, Aspergillus niger, Fusarium sp, Trichoderma mf 2, Asperegillus flavus, Trichoderma mf 3, Fusarium sp, Trichoderma mf 4.

This study aims to determine the level of insecticide use and the intensity of pest leafminer fly attacks on local shallots in Palu in Guntarano Village. The research was conducted in Guntarano Village from April to July 2021. This study used a direct survey method using a structured questionnaire to obtain primary data by interviewing 10 respondent farmers. Respondents were selected based on their daily activities as local shallot farmers in Palu. Determination of respondents was carried out using a simple random sample method, while the observation of the percentage of Liriomyza sp pests was carried out at intervals of once every 7 days for 1 month. The results showed that the respondent farmers in cultivating shallots controlled herbivorous insects with the application of insecticides, with an interval of 1-3 times a week as many as 90% of respondent farmers had never participated in Integrated Pest Control (IPC) training activities. Farmers who used doses while the average percentage of Liriomyza, sp was the highest in the fourth week of 49.55%.
