“…The QuEChERS method involves an extraction phase utilizing acetonitrile (ACN) and partitioning with MgSO4 at room temperature. The extraction is subjected to cleanup using dispersive solid-phase extraction (dSPE) materials, namely primary secondary amine (PSA), octadecyl modified silica (C18), and graphite carbon black (GCB), as outlined by Malhat et al (2023). In the process, 5 grams of frozen homogenized ground rice were accurately weighed and placed into a 50 mL polypropylene centrifuge tube.…”

Amid escalating concerns about pesticide residues in agricultural product, this study conducts a meticulous comparative analysis of pesticide residue profiles in locally grown rice, aiming to contribute essential insights for informed decision-making in agriculture. The overarching problem addressed involves identifying pesticides in rice from conventional and sustainable farming and understanding their potential environmental and health implications on food safety. Utilizing HPLC/MS-MS, the research discerns a notable absence of over 500 pesticide types in rice cultivated according to good agricultural practices (GAP). Conversely, rice from fields deviating from GAP guidelines reveals the presence of 7 pesticide active ingredients, with 2 exceeding globally established residue limits by twice the recommended amount. Notably, bifenthrin and tebuconazole, uncommonly used in the last one years, are identified. This study underscores the urgency of adhering to sustainable agricultural practices for the safety and quality of rice, offering critical insights for future research. It not only contributes to current knowledge but also emphasizes the global necessity of safe agricultural practices to safeguard our food supply.

“…However, the use of synthetic pesticides should ideally be restricted further due to the potential residue they leave on agricultural products and in the environment, posing risks to both humans and other non-target organisms (Purnama & Mutamima, 2023;Malhat et al, 2023;Syafrani et al, 2022). Therefore, alternative methods are essential for anthracnose control, particularly in field settings.…”

Anthracnose, a primary disease in chili plants caused by the pathogen fungus Colletotrichum sp., has proven significant losses by affecting harvests and inducing fruit decay. Control measures using synthetic pesticides have been implemented but yielded unsatisfactory results. The utilization of resistant varieties stands as a pertinent approach in early control efforts to minimize harvest losses. Additionally, the use of resistant varieties is a crucial component of integrated disease control implementation. This study aims to investigate the resistance levels of ten chili varieties commonly grown in swampy areas against specific isolates of Colletotrichum sp. present in swampy locations. The research, conducted in a randomized complete design in a greenhouse, tested ten varieties of cayenne pepper typically cultivated in swampy areas. The results revealed that the Hiyung variety is Susceptible, while Bara, Dewata 43 F1, Tiung Tanjung, Genie, Sekar, and CR-9 varieties exhibit moderate resistance. Conversely, Tiung Ulin, Alip, and Sret varieties are classified as resistant. The incubation period for tested cayenne pepper varieties varied, ranging from 3.5 to 5.3 days. A longer incubation period indicates greater resistance to anthracnose in chili varieties. The selection of resistant varieties is a pivotal step in anthracnose management, not only to minimize harvest losses but also to support an effective integrated control approach.
