  • Fungicides within the West: wonderful wheat crop, dry bias, however there’s soil moisture, is there a profit to fungicide with excessive warmth on the way in which? What’s your yield potential? Will grain fill be brief? For some areas with no soil moisture, cease spending cash on the crop
  • However, if you happen to’ve received some strong potential and soil moisture, fungicides provide some stay-green advantages, too (even with decrease illness strain)
  • Ankle-high wheat in head, don’t spend a penny
