Our Mission
SprayCalc Pro was created to address a critical need in agriculture, landscaping, and home gardening: accurate chemical mixing calculations. We believe that precision in pesticide, herbicide, and fertilizer applications protects the environment, saves money, and improves results.
Why We Exist
Every year, billions of dollars of agricultural chemicals are applied incorrectly due to miscalculations. Over-application harms the environment and wastes money. Under-application leads to ineffective pest control and crop losses. We created these free calculators to eliminate calculation errors and promote responsible chemical use.
Whether you're a homeowner treating your lawn, a farmer managing hundreds of acres, or a professional landscaper serving clients, our tools provide the accuracy you need without complex math or expensive software.
