![]() The results from the second location showed that LRC112 drench provided control of wireworms. One of the two locations did not show any significant differences among the treatments on potato. Treatment differences were determined using Tukey's HSD (honest significant difference) test, α = 0.05. Results were analyzed by Analysis of Variance, with pre-treatment population levels of wireworms used as covariates in the analysis of potato and corn trials in one location, and levels of wireworms from guard rows of corn trials in one location also used as a covariate. Test treatments were compared with industry standard (phorate) and untreated controls.The experimental design was a randomized complete block design with six blocks per trial. Mycelia granules of Metarhizium anisopliae were applied in field trials to test a range of formulations and application methods for reducing wireworm damage to potato and corn. The project was conducted at two locations (for each trial) in Agassiz, British Columbia in 2007. This project addressed both of these constraints by field testing a mycelial granule formulation of the LRC112 strain. However there remain constraints in moving this isolate toward commercialization: (i) environmental factors and targeting of the pest and (ii) production and formulation of the isolate. ![]() This strain has been shown to infect and kill wireworms under field conditions. Metarhizium anisopliae strain LRC112 (hereafter referred to as LRC112), a fungal pathogen of insects, has shown promise as a microbial insecticide for wireworms. However, in Canada almost all pesticides targeting wireworms are now unavailable due to low market potential, environmental concerns, and high risk assessments. These pests have been controlled until recently through the use of effective insecticides and by the residual activity of chlorinated hydrocarbon insecticides used during the middle part of the 20th century. Wireworms ( Agriotes obscurus) induce damage to several crops, primarily by feeding on plant roots and tubers.
