Realistic Crop Pests

This mod adds a dynamic and realistic pest system for all field crops. Infestation is calculated based on crop type, growth stage, season, region, crop rotation and weather conditions. Pests spread locally across the field, can develop further over time and cause real yield losses.

Dynamic Pest System
Various agricultural pests such as the European corn borer, Colorado potato beetle, grain aphid, pollen beetle and many more are simulated with individual biological properties. Each species has its own host plants, activity periods, development stages, reproduction rates, damage potential and control options.

Local Infestation
Pests do not automatically infest an entire field evenly. An infestation starts locally and can spread from individual hotspots, creating zones with different pest pressure within the same field.

Weather, Season and Region
Temperature, frost, precipitation, humidity, wind, solar radiation and soil temperature all influence pest development. Extreme conditions can reduce activity or wipe out populations. The possible pest species also depend on the region.

Crop Rotation and Tillage
Populations can overwinter in the soil or in crop residues. Repeated cultivation of the same crop increases the risk, while crop rotation can reduce certain populations. Plowing, cultivating and mulching also affect pest populations and overwintering stages.

Crop Protection
Real plant protection products like Coragen, Mospilan SG, Teppeki, Carnadine, Karate Zeon, Decis forte and Nexsuba are available for treatment. Work areas, working width, section control and variable work width are fully supported. Products also feature their own realistic consumption.

Yield Losses
Pests reduce the actual achievable yield depending on infestation strength, development stage and duration. Multiple simultaneous pests can collectively impact the harvest.

Pest Map and HUD
A dedicated "Pest Infestation" view is available in the map menu, showing local infestation pressure from 1–100% while unaffected areas remain transparent. A compact HUD on foot displays crop, pest species, infestation strength, damage so far and active treatment.

Multiplayer and Savegame
Fully supports multiplayer and dedicated servers. Pest simulation runs server-side and is synchronized with all clients. All pest states are saved with the savegame.

Performance
Event-driven design with no permanent full-field scanner. Calculations mainly occur at day changes and relevant game events.

Note: If Realistic Water & Soil Management (RWSM) is installed, its climate, country and weather data will be used automatically.
