Weeds & Herbicides
As part of an IPM program it is important to scout for, and identify weeds, specifically during the Critical Weed-free Period, the short time when weed interference can cause large yield losses.
As well, it is important to identify herbicide injury. All herbicides can cause crop injury, either from soil splash on the leaves, root uptake, post-emergent application, spray drift or spray overlaps. Herbicide carry-over can also damage subsequent crops.
