Wheat Pete's Word, May 1: Watching for the flag leaf, insect feeding, frost damage, and go-time


There’s something about the calendar flip to May that injects a sense of urgency to planting and seeding plans. Is it go time? Well, it might be — and already has been for some both in the west and the east — but the weather calls the shots this week, and some areas are just too wet in Ontario, says Peter Johnson.

In this episode of Wheat Pete’s Word, Johnson explains why early insect pressure might be really high for those who already have seed in the ground, why identifying the wheat flag leaf is so important and might have you changing tank mixes, and he’s got some tips on managing well-advanced wheat.
