YielixApply Safely, Stay Compliant, Spray Smarter
Pesticide application is one of the most regulated activities on the farm. Getting the rate wrong wastes product and money; getting the timing wrong can endanger workers or leave illegal residues on harvested crops. These calculators help you work through each decision — from converting a label rate into product per tank load, to tracking restricted entry and pre-harvest intervals for every product you apply.
Before you spray, the IPM cost-benefit calculator helps you decide whether treatment is economically justified based on pest counts, crop value at risk, and treatment costs. When conditions are marginal, the spray drift risk calculator scores wind speed, nozzle type, boom height, and buffer distances to flag applications that are likely to drift off-target.
Every calculator references label-compliance principles and standard agronomic methods. Use the task groupings below to find the right tool for your workflow, or browse all four pest and spray calculators. Each calculator page includes a worked example, input explanations, and links to related guides covering spray application rates, REI/PHI regulations, and integrated pest management strategies.
Common Pest & Spray Tasks
Calculate Spray Rates and Tank Mixes
Convert label rates into product per tank load, calculate dilution volumes for your sprayer capacity, and determine total product needed for the job.
Track Compliance Intervals
Monitor restricted entry intervals (REI) and pre-harvest intervals (PHI) with countdown tracking so workers and harvest crews stay safe and compliant.
Evaluate Treatment Economics
Decide whether a pest treatment is economically justified by comparing pest pressure against economic thresholds and calculating treatment ROI.
