Measuring and Dilution Equipment
Accurate measuring tools ensuring proper pesticide dilution rates - graduated cylinders, measuring cups, mixing containers for label compliance.
Detailed Overview
Accurate mixing critical for effectiveness and legal compliance. Tools needed: (1) Graduated cylinders: measure small volumes of concentrated product (1-100 ml). Essential for accurate dilution. (2) Measuring cups: larger volumes (cups, quarts). (3) Measuring spoons: very small amounts (tablespoons, teaspoons). (4) Spray tank markings: gallon markers on sprayer tanks for water measurement. (5) Scales: weigh dry products (wettable powders, granules) requiring weight-based mixing. (6) Mixing containers: dedicated containers for mixing concentrates. Never use food containers. (7) Stirring paddles: ensure complete mixing. (8) Funnel: transfer products without spills. Dilution calculations: product label specifies rate (ounces per gallon, percent concentration). Calculate amount needed: determine total spray volume needed, calculate amount of concentrate required, measure concentrate accurately, add to partial tank of water, agitate while adding, fill tank to final volume with water. Common mistakes: adding water to concentrate (correct is concentrate to water), eyeballing measurements (use graduated tools), improper math (double-check calculations), using contaminated measuring tools. Over-dilution reduces effectiveness below label requirements. Under-dilution wastes product and may violate maximum application rate. Keep dilution charts readily available for common mixes.
When to Use
Accurately measure and mix all pesticides per label directions. Use graduated cylinders for small volumes. Calculate dilutions carefully. Mix in proper order. Record dilutions for documentation.
