Crop Sprayer App: Dosage calculator for plant protection products

Optimizing Pesticide Application for Sustainable Agriculture

The Crop Sprayer App enables users to determine accurate pesticide dosages by considering factors such as sprayer tank size, sprayer output, and application area. It calculates the amount of pesticide concentrate needed per tank and the total quantity for the entire spraying operation. The app operates offline after initial download, ensuring accessibility in remote areas.

This technology is pre-validated.

Scaling readiness: idea maturity 9/9; level of use 7/9

Adults 18 and over: Positive medium

Adult users will gain ability to quickly run important calculations on product use. This is to avoid errors during manual miscalculation which may increase risks to the individual and the environment, and cause more product to be applied than required.

The poor: Positive medium

Smallholder farmers in low and lower middle income countries are the ultimate beneficiary of this technology. Knowing the right application of crop protection products should reduce the risk of too much being purchased and applied.

Women: Positive medium

The tool has been designed to be available in local languages, and to work offline and on lower specification phones that we found women farmers and advisors have available.

Biodiversity: Not verified

The judicious use of crop protection products as a result of using the Crop Sprayer app may reduce run-off or impacts on non-target organisms, but this has not been tested.

Environmental health: Not verified

The judicious use of crop protection products as a result of using the Crop Sprayer app may reduce the amount of product that gets applied, and reduce the amount that may end up as run-off, but this has not been tested.

Problem

Food Security Challenges: Up to 40% of crops are lost to pests and diseases, directly impacting the food security of vulnerable communities and hindering sustainable development efforts.
Inefficient Pesticide Use: Research indicates that up to 75% of pesticide applications are misapplied or overused. This inefficiency increases production costs, contributes to environmental degradation, and jeopardizes community health.
Barriers to Sustainable Farming: The lack of precise pesticide application tools prevents smallholder farmers from adopting efficient, sustainable practices, undermining efforts to improve livelihoods and promote long-term agricultural resilience.

Solution

Sustainable Pesticide Application: The Crop Sprayer App ensures precise pesticide dosing, reducing chemical waste by up to 25–30% and minimizing environmental harm. This contributes to improved crop yields and food security in vulnerable communities.
Capacity Building and Training: Its user-friendly interface and offline functionality make the app an ideal tool for training smallholder farmers and agricultural advisors in safe, efficient pest management practices.
Data-Driven Decision Making: The app collects reliable data on pesticide usage, enabling development partners to monitor program impact, optimize resource allocation, and design targeted interventions for sustainable agriculture.
Empowering Communities: By reducing input costs and increasing productivity, the technology supports livelihood improvements, contributing to poverty reduction and long-term agricultural resilience.

Key points to design your program

The Crop Sprayer App is designed to enhance agricultural productivity, promote environmental sustainability, and ensure the safety of pesticide applicators. By facilitating precise pesticide application, it contributes to efficient pest and disease management while mitigating the impacts of climate change.

To integrate this technology in your program, key activities are:

Community Engagement: Implement awareness campaigns within target communities to promote the adoption of the Crop Sprayer App, focusing on its benefits for health, environment, and productivity.
Capacity Building: Organize training sessions for local farmers and agricultural advisors to ensure effective utilization of the app, fostering self-reliance and sustainable practices.
Resource Provision: Allocate funds for procuring Android devices and data plans necessary for app operation in under-resourced areas.
Monitoring and Evaluation: Establish metrics to assess the app's impact on pesticide usage, crop yields, and environmental health, using data to inform future agricultural interventions.

Scaling Readiness describes how complete a technology’s development is and its ability to be scaled. It produces a score that measures a technology’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.
