CROP SCENE INVESTIGATION – 19: What caused Roger’s aphid infestation?


The expression “more than meets the eye” often applies when there is trouble brewing in a soybean crop. This was certainly the case when Roger from Perth County called in late June.  

“My soybeans aren’t looking good in one part of a field,” he said. “The plants are discoloured. I haven’t had a chance to scout very closely, but I can see some are yellow and some are purplish-black.”

I agreed to head over after I’d finished another farm visit. So far, the growing season had been droughty and I’d been receiving lots of calls for agronomic advice.
