Lygus bugs, pre-harvest intervals, grasshoppers and more

Weather synopsis – Below is the Accumulated Precipitation for the Growing Season

Grasshoppers - This week, most grasshopper populations across the prairies are well into the adult stage (>70 % adults). Populations are most advanced in Manitoba, southern Saskatchewan and in the Peace River region

Lygus Bugs (L. lineolaris, L. keltoni, L. borealis, L. elisus) – Remember, hot dry weather favors the buildup of lygus bug populations. The economic threshold for lygus bugs in canola is applied at late flower and early pod stages.
