Pesticide Dilution Calculator
Concentrate needed from spray volume and dilution ratio
Dilution
Concentrate needed
0 mL
e.g. 1000x = 1 mL concentrate per 1 L water. 20 L at 1000x needs 20 mL.
By dilution ratio
⚠️ This calculator is a simple reference tool based on general agricultural guidelines, recommended dilution ratios, mixing proportions and publicly available references. In real field conditions the appropriate dilution, dose and spray volume can vary with crop type and variety, growth stage, weather, soil, water quality, growing method and the quality/concentration of the materials used, so results may differ from actual needs. Pesticides, fertilizers, liquid fertilizers, microbial inputs, JADAM Sulfur, JADAM Wetting Agent and other natural/chemical materials can cause phytotoxicity, stunting, crop loss, disease or yield reduction through overuse, improper dilution or mixing with incompatible substances. Always check the product label, manufacturer guidance and relevant authorities, and test on a small area before full use. calcstool.com assumes no legal liability for any direct or indirect damage arising from manufacturing, diluting, mixing, fertilizing, spraying or other agricultural activity based on these results.
FAQ
How is pesticide dilution calculated?
Concentrate (mL) = water (L) × 1000 ÷ dilution ratio. For 20 L of water at 1000x, you need 20 mL of concentrate.
What does 1000x dilution mean?
It means 1 part concentrate to 1000 parts water — i.e. 1 mL concentrate per liter of water, or 20 mL per 20 L.
Where do I find the right ratio?
Recommended ratios differ by crop and pest for each pesticide. Always follow the product label and check tank-mix compatibility.
