Abstract

This study aimed to examine the effectiveness of some insecticides on the population development and attack Liriomyza sp on local Palu onions. The research conducted from Februari to April 2017, at Guntarano village, Tanantovea Sub-District, Donggala District. The study used Randomized Block Design (RAK) consisting of four treatments, namely Po.Control; P1. Abamectin; P2. Azadiractin; P3. Dimohipo. Each treatment was repeated three times so that 12 treatments were obtained. The results showed that the insecticidal treatment had an effect on the development of the varied Liriomyza sp. Adult population at various plant age levels. Observations on plant age 5 and 6 of MST showed that abamectin insecticides were effective in suppressing the growth larvae populations of Liriomyza sp compared with the treatment of Azadiractin, Dimohipo and non-treated insecticides.

Abstract

Effect of Frequency and Application of Abamectin Insecticides on Population Abundance and Attack Level of Leafminer Liriomyza, spp. (Diptera: Agromysidae) is one of the main pests on the Lembah Palu red onion, where this pest is relatively new in the Palu Valley. The aim of the study was to examine the effect of frequency and application of insecticides on population abundance, and the attack rate of L. chinensis (Diptera: Agromyzidae) on the Lembah Palu red onion plant under applied and unapplied insecticide. The treatment of abamectin insecticide was applied once a week with a concentration of 1 ml of formulation per liter of water, beginning at the age of 2 MST and ending at 7 MST. The results showed that there were 2 species of Liriomyza, spp associated with Palu valley red onion i.e. Liriomyza chinensis and Liriomyza sativae. This research found that the application of Abamectin insecticides significantly affected population development and the percentage of Liriomyza, spp. on the lembah Palu red onion.

Abstract

This study aims to study and determine the behavior of farmers in the use of pesticides on shallots in Wombo Mpanau Village, Tanantovea District. This study uses a simple random method. The data obtained is collected, processed and analyzed. Analysis was carried out to determine the frequency of data in each variable. Primary data obtained through interviews were analyzed to provide a concise picture of groups of data in one frequency table. Types of pests that attack onion in Wombo Mpanau Village are leaf caterpillars, leaf flies, trips, flour dew, and fusarium wilt. The most widely used pest control method is the use of chemical pesticides, which reaches 70% of respondents. The knowledge of farmers on the application of pesticides is relatively good, namely 100% of respondents apply pesticides when there are symptoms of attack and if other controls are unable to overcome the pest attack. Knowledge of farmers on the use of doses of pesticides is relatively good, namely 100% of respondents use the dosage according to the recommendations listed on the packaging. The actions of farmers when applying pesticides in general are not mixing pesticides. The majority of respondents have taken the right action in terms of storing semrot and pesticides in a special place. But on the other hand the awareness of farmers is still low, because there are still many farmers who wash sprayers in rivers or ditches.

Abstract

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.

Abstract

Spodoptera frugiperda is a new pest in Central Sulawesi attacks maize crops. It was reported in 2019, known in Sigi, Donggala, Touna, Bangga, Tolitoli, Buol, and Palu City Regencies. Also, this pest is spreading rapidly by threatening maize production in Central Sulawesi. This study aims to measure the population and intensity of Spodoptera frugiperda attacks on maizes in Tulo Village, Dolo Sub-district, Sigi Regency. The study, conducted from January to March 2020, used a survey method and selected sampling. Our location takes each plot measuring 2x2 m. Population observations were carried out by collecting larvae found in the sample plants. The attack's intensity was carried out by counting the number of leaves showing symptoms of an attack on the top leaves. Calculation of the proportion of attacks was carried out by the Davis method. The results showed that the highest S. frugiperda population at the age of 14 days after planting. The intensity of S. frugiperda attack on maize was relatively high at the age of 42 days after planting, with an average attack of 65.24%. Climatic data during this period, an average of 28.76-29.43 ℃ with air influence was 71.1-72%.

Abstract

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%.
