Built for Jamaica and the broader Caribbean

Most farming software assumes a temperate season: a spring planting, a summer of growth, a frost that ends the pest year. None of that describes Jamaica or the rest of the Caribbean. Pest generations run continuously, the wet season drives disease pressure that northern guidance never accounts for, and the products on the local market are not the ones a US or European app will recommend.

PlantArmor is built around what is actually grown and actually available here, starting with Jamaica: products from Jamaican suppliers and guidance that matches local crop calendars. Growers across the Caribbean can use it today; money shows in Jamaican dollars, for now.

Common questions

What does PlantArmor do?

It helps you identify what is wrong with a crop, decide how to treat it, plan spray schedules around re-entry and pre-harvest intervals, and keep the cost and traceability records buyers ask for.

Does it work without internet?

Yes. The reference library and your farm records work offline, which matters on plots with little or no mobile signal. Records sync when you are back in coverage.

How much does it cost?

PlantArmor is free to use.

Which crops does it cover?

18 crops grown in Jamaica, including scotch bonnet pepper, tomato, sweet pepper, carrot, coffee, corn, crucifers (cabbage/broccoli), cucumber and others. Every crop has a free public guide.
