Fungicides and Mycorrhizae

PESTICIDES & MYCORRHIZAL FUNGI

Fungicides
Care must be taken when applying fungicides to mycorrhizal plants though there is plenty of scope to combine mycorrhizal fungi with fungicides; in what is known as an enhanced integrated pest management programme IPM.

The following guidelines will help you get the best results with mycorrhizae. It must be remembered that at recommended label rates it is highly unlikely that any fungicide will completely eliminate mycorrhizal colonisation.

Non Systemic Fungicides

Foliar Application – Has no detrimental effect and can be used at any time.

Soil Drench – Do not apply within 3-4 weeks of planting or applying mycorrhizal inoculant. Once the fungi have colonised the root system non systemic fungicides have little effect as they do not penetrate the root system.

Systemic Fungicides
Foliar Application – fungicide builds up in the plant and is detrimental to mycorrhizal colonization. Do not apply for 2-3 weeks before inoculation and 3-4 weeks after inoculation.

Soil Drench – fungicide builds up in the plant and is detrimental to mycorrhizal colonization. Do not apply for 3 weeks before inoculation and 3-4 weeks after inoculation.

Insecticides
There are no reports of insecticides harming mycorrhizal fungi when applied at recommended label rates.

Herbicides
If herbicides are used to kill off a wide area of plants then the mycorrhizae will only survive a short time in the soil without a host plant and inoculation of the new plants will be needed.
