Phytotoxicity

Plant injury (phytotoxicity) may occur when chemicals are employed to protect plants from pests, fertilize plants, regulate plant growth, and so forth. Phytotoxicity can occur in the following situations:

  • A material is properly applied directly to the plant during adverse environmental conditions.
  • A material is applied improperly.
  • A spray, dust, or vapor drifts from the target crop to a sensitive crop.
  • Runoff carries a chemical to a sensitive crop.
  • Persistent residues accumulate in the soil or on the plant.
