SPUDSMART.COM SUMMER 201516 PUT THE INTEGRATED BACK IN IPM In the short term wireworm damage will likely continue to trouble Canadian potato growers and as far as Noronha is concerned dependence on one control mechanism is not the way to go. Growers are going to have to change the way they do things. They are going to have to manage this insect says Noronha. Were so used to using one technique and it works but we have to put the integrated back into integrated pest management. Not just monitoring and spraying that is not the option with these insects. You really need to integrate all techniques and manage them. In addition to chemical control techniques such as crop rotation with crops such as brown mustard and buckwheat and ploughing down green material in the fall as opposed to the spring when this material will attract and keep wireworms below the soil surface will help keep wireworm populations in check. Were trying to put as many tools as we can in the toolbox. Right now we have chemicals we have rotation and we have ploughno plough but were continuing to look at the biology of this insect to see what else we can do to control it and get the population down says Noronha.Tuber containing mature larvae of the Pacific Coast wireworm Limonius canus.
