Herbicides Calculator

Reduce pesticide and herbicide losses with IITA's herbicide calculator

The "IITA Herbicides Calculator" is a solution designed to address the prevalent issue of pesticide misuse resulting from inadequate calibration of spray tanks. It permits farmers to estimate the required quantity of herbicides for knapsack sprayers. This tool was developed using Java language, the Ionic framework, and Android Studio, ensuring its robustness and usability. Tested for effectiveness and reliability by researchers, this technology assists in calibrating the application of herbicides and other pesticides specifically for knapsack sprayers. It's important to note that the tool does not involve specific compositions or sequences of products or technologies.

This technology is TAAT1 validated.

Problem

The widespread misuse of pesticides (including herbicides) due to poor calibration of spray tanks.
Loss of inputs (pesticides or herbicides) during applications.

Residue of chemical products in crops due to overdosing of pesticides or herbicides.

Solution

Accurate Quantity Estimation: The technology ensures the precise application of pesticides, mitigating issues related to over or under-dosing.
Promoting Effectiveness: "IITA Herbicides Calculator" promotes the effectiveness of herbicides, facilitating their optimal application.

Key points to design your project

This technology aims to enhance food security, promote environmental protection, and ensure the safety of pesticide applicators. Simultaneously, it contributes to efficient and sustainable management of plant pests and diseases while mitigating the impacts of climate change.

To integrate this technology into your project, create a list of activities and prerequisites, including:

Raising awareness among farmers about the benefits and availability of the IITA Herbicide calculator.
Establishing training of trainers and collective action programs.
Linking producers to financial support and markets.

- Estimate the number of IITA Herbicide calculator subscriptions needed for your project, considering that the product costs 30,000 USD.

- As the technology is a digital tool, include the cost of android phones and data. Training is crucial, and a team of trainers could provide support throughout the project, including post-training. Develop communication support for the technology, such as flyers, videos, and radio broadcasts.

To implement the technology in your country, consider collaborating with agricultural development institutes, agro-chemical companies and spray service providers.

Enter Herbicide Dosage: Input the recommended dosage of the herbicide in liters per hectare as indicated on the herbicide label.
Measure Water Dispensed: Measure the volume of water dispensed on a 10m x 10m plot. (To calculate the water sprayed on a 10m x 10m plot, measure an area of 10m x 10m, equal to 100m². Fill water in your knapsack spray tank and spray the measured area following a straight path at a nozzle height equivalent to your knee level. Enter the volume of water dispensed from your knapsack spray tank onto the 10m x 10m plot.)
Enter Knapsack Tank Capacity: Input the capacity of your knapsack spray tank in liters.
Calculate Herbicide Dosage: Press the "Calculate Volume" button to obtain the precise dosage of the herbicide required to be added to your knapsack spray tank before filling it with water for spraying.
