About Pesticide Reference
The Pesticide Reference is a comprehensive, searchable quick-reference for agricultural crop protection. It covers six major categories: pesticide classification (insecticides, fungicides, herbicides, PGRs), safe-use standards (PHI, maximum application counts, dilution rates), residue limits (MRL, PLS Positive List System, ADI), toxicity and risk assessment (WHO classification, PPE, poisoning first aid), control techniques (spray timing for rice and fruit, IRM/FRAC resistance management, IPM, tank mix compatibility, drone spraying), and eco-friendly control (organic-approved materials, Bordeaux mixture, natural enemies).
This reference is built for agricultural professionals, crop consultants, agronomists, farm managers, and students in plant protection or agronomy programs. Every entry includes practical examples such as specific active ingredients with their target crops, PHI intervals, MRL values in mg/kg, dilution calculations, and IRAC/FRAC mode-of-action group numbers. The content is organized by category and fully searchable, making it a fast alternative to flipping through pesticide labels or regulatory databases.
All content loads and renders entirely in your browser with zero server processing. The reference works offline once loaded, supports dark mode for field use at dawn or dusk, and is fully responsive on phones, tablets, and desktops. No login, no download, and no personal data collection.

Frequently Asked Questions
What pesticide categories does this reference cover?
It covers insecticides (organophosphates, carbamates, pyrethroids, neonicotinoids, Bt), fungicides (protectant, systemic, strobilurins, triazoles), herbicides (selective and non-selective by mode of action), and plant growth regulators (ethephon, GA3, paclobutrazol). Each entry lists representative active ingredients and their use contexts.
How do I look up the Pre-Harvest Interval (PHI) for a specific crop?
Search for "PHI" or the specific crop name. The PHI entry lists common active ingredient and crop combinations with their required days before harvest, for example imidacloprid on cabbage requires 14 days. For official values, always verify on the national pesticide information system (psis.rda.go.kr in Korea).
What is the PLS (Positive List System) and how does it affect residue limits?
PLS, fully implemented in Korea since January 1, 2019, means only pesticides officially registered for a specific crop are permitted. Any unregistered pesticide residue is subject to a uniform default limit of 0.01 mg/kg. The reference includes this rule and key MRL values for common active ingredients.
How do I use IRAC and FRAC groups for resistance management?
The reference lists major IRAC mode-of-action groups for insecticides (Group 1 AChE inhibitors, Group 3 pyrethroids, Group 4 neonicotinoids, Group 28 ryanodine receptor) and FRAC codes for fungicides (M multi-site, 1 MBC, 3 DMI, 11 QoI). Rotate between different group numbers each spray to prevent resistance buildup.
What organic-approved pest control materials are listed?
The reference covers microbial agents (Bt, Beauveria bassiana, Metarhizium), plant extracts (neem, derris, pyrethrum), inorganic materials (Bordeaux mixture, lime sulfur), insect pheromones for mating disruption and lure traps, and natural enemies (Phytoseiulus for mites, Aphidius for aphids, Encarsia for whiteflies).
Does the reference include drone spraying guidelines?
Yes. The drone spraying entry covers dilution rates (1/8 to 1/10 of ground spraying), spray volume (0.8-1.0 L per 10a), flight altitude (2-3 m above crop canopy), flight speed (15-20 km/h), swath width (3-5 m), and the requirement to use only drone-registered pesticide products.
How do I calculate pesticide dilution ratios?
The dilution entry explains that 1000x means 1 mL concentrate plus 999 mL water, 2000x means 0.5 mL per liter, and 500x means 2 mL per liter. It also provides standard spray volumes: 100-200 L per 10a for open fields and 300-500 L per 10a for orchards.
What first aid information is available for pesticide poisoning?
The reference includes emergency response steps: remove contaminated clothing and wash with soap and water for skin contact, rinse eyes with clean water for 15+ minutes, move to fresh air for inhalation, and notes that vomiting should not be induced for organophosphate ingestion. Emergency contacts are provided.
