Biofumigation: Practical information, advantages and disadvantages

Biofumigation is the use of green manures crops which release biocidal molecules into the soil after their incor-poration. This best practice was developed in several countries to cope with the withdrawal of methyl bromi-de, a most effective but controversial chemical soil fu-migant. The effect of biofumigation is partly based on the release of natural toxic substances but also on their effect as a green manure plant. The effect of green ma-nures and cover crops are explained in two Best4Soil vi-deos and factsheets.
