πŸ› Pest Population Growth Model

Model SF4-S.001

Project pest population growth using logistic model. Predict when action thresholds will be reached based on growth rate and carrying capacity.

Typical: 0.05-0.30 depending on species
Economic or regulatory threshold for intervention

πŸ“Š Economic Injury Level (EIL)

Model SF4-S.002

Calculate the pest density at which control costs equal crop damage. The foundation of IPM decision-making.

Percentage of crop value lost per pest per unit area

πŸ—ΊοΈ Quarantine Zone Calculator

Model SF4-S.003

Model quarantine zone size based on detection sites, pest spread rate, and buffer requirements for invasive species containment.

Regulatory quarantine radius per detection
Trees, crops, or other hosts per square mile

🐞 Biocontrol Agent Efficacy

Model SF4-S.004

Model biological control agent performance. Simulate predator-prey dynamics and compare biocontrol effectiveness against chemical alternatives.

Enter as decimal: 15 = 0.15

⚑ Invasive Spread Risk Index

Model SF4-S.005

Assess invasion risk using a multi-factor scoring system. Evaluates pathway connectivity, climate match, host availability, and natural enemy absence.

Trade volume, transport routes, proximity to ports
Match between origin and destination climate
Density and distribution of susceptible hosts
Lack of predators/parasites in new range
Surveillance capability (10=excellent, 1=poor)

Why AgrStak 🌾 Invasive Species Tools?

Aligned with USDA Secretary Rollins' Priority #3: Protecting the Integrity of American Agriculture from Invasive Species. AgrStak's tools help researchers, regulators, and pest managers model invasive threats, set economic thresholds, design quarantine zones, and evaluate biocontrol strategies.
