Landmark agronomist shares basic rules he adheres to.

This article draws on conversations with Landmark senior agronomist Paul McIntosh. He says  the timing of spray-out was critical to preserving yield and grain quality and avoiding lodging issues.

  • Don’t judge physiological maturity by the colour of grain; get out into the crop and look at black point percentage numbers on the sorghum seed; and look on the bottom of the sorghum head on the southern side to determine if physiological maturity has reached this last area of grain turning.
  • If grain moisture is less than 25 percent with over 90-odd percent physiological maturity then spray-out results are going to be far more positive and much quicker.
