Mixing and batching for agricultural chemical application

Mixing and batching for agricultural chemical application

Published: 12 Jun 2025

This publication talks about how most mixing and batching problems are caused by mixing errors. Adding chemicals in the right order and waiting before adding more chemicals can help.

Key points

  • Always follow the correct mixing order and allow enough time before adding more products.
  • When mixing more than one product in a tank, check they can be safely mixed together before you start.
  • Always read the product label and follow the instructions for mixing.
  • Use good-quality water, especially when mixing more than one product, as poor water quality can cause problems.
  • If you are mixing a batch for the first time, conduct a jar test (see ‘Other spray resources’ on page 43) to check if the mix works well.
