Data Maturity Baseline

This profile contains verified disease data from extension databases. Regional field notes and expert review are in progress.

Leaves become pale yellow or whitish from nutrient imbalance in high-pH or alkaline soils, affecting growth. Improve soil chemistry with sulfur or organic matter amendments. Provide proper nutrition and ensure adequate drainage.

Adjust soil pH to 6.2, which is optimal for strawberry. Check plant's proximity to newly poured concrete.

Management

Cultural Controls

  • Adjust soil pH to 6.2, which is optimal for strawberry.
  • Check plant's proximity to newly poured concrete.
  • New concrete leaches lime into the surrounding soil, raising the pH.
  • Use iron chelate, either as a soil treatment or by foliar feeding, to quickly help chlorotic plants.
  • Read and follow all label instructions.
  • Reference Zaiter, H.
