Evaluation of ectomycorrhizal respiration for remediation of pesticides in forestry

Abstract

The ectomycorrhizal (ECM) can be used on forest seedlings production. This work raises the possibility that these microorganisms can also assist the degradation of organic molecules of pesticides registered on forestry. This study aimed to evaluate the microbial respiration of forest substrate inoculated with ECM, since the effect could be important in agroquemichal remediation. There was used a completely randomized design with two treatments and six replications. As a control (T0), was used the commercial substrate. As treatment 1 (T1), the substrate was mechanically mixed with mycorrhizal inoculant. It was possible to infer that the control group evolved 8,4167.10-4 mol CO2.dm-3.day, and treatment with mycorrhizal soil, 1,0202.10-3 mol CO2.dm-3.day. Notably, the T1 evolved a little more, probably due to mycorrhizal inoculated, but without significant difference. It presents arguments about the potential use of ECM roots remediation, and also contextualized for integrated pest management on forestry, given the imposition of forest certification programs to reduce chemical control.
