Nematicide
Nematicides are pesticides used to kill roundworms (nematodes) and other pests living in the soil.
The nematicides include pesticides from different chemical groups. Short-chain bromine and chlorinated hydrocarbons and dithiocarbamates are particularly important. To be effective, they must be well distributed in the soil. That is why fumigants or substances soluble in water are usually used . A number of nematicides are also effective against insects and fungi .
Classic nematicides are:
| Active ingredient | Trade name |
|---|---|
| Dichloropropane + dichloropropene | Shell DD |
| Methyl isothiocyanate (MIC) | Trapex |
| Metam sodium | Vapam |
| Dazomet | Basamide |
| Methyl bromide | Terabolic |
In America, 1,2-dibromo-3-chloropropane (Nemagon) was also used. Soil fumigants are no longer permitted in Germany today.
The chemical nematicides have to be replaced by biological or thermal processes such as steaming with superheated steam .
