Saskatchewan sees aphid infestations
By Top Crop Manager
July 23, 2015 - Reports of aphid infestations have been common during the past couple of weeks with areas affected throughout Saskatchewan. Many of the reports have been from southwest Saskatchewan in lentil crops. Both pea and lentil appear to be the most affected.
Timing and necessity of insecticide applications should be treated on a case by case basis. Early application of insecticide likely won't provide a yield response but will affect beneficial predators (e.g. lady beetle larvae and adults) and wasp parasites. Late application would have no beneficial result and will be an unnecessary expense as the aphids cannot damage crops that have completed seed filling.
