Schwefelsäure zusezen, und damit die Pflanzen alle andere Tage 6 Tage hindurch begießen. – Gegen die Erdflöhe wird empfohlen, einige Rettigpflanzen unter die Kohlpflanzen zu sezen, indem sich dieses Ungeziefer dann auf erstere wirft und leztere verschont. – Gegen die Engerlinge soll man Schweine auf die umgebrochenen Felder lassen. – Gegen die Feldschneken soll man junge, 3 Wochen alte Enten (aber nicht ältere) ausschiken; oder man soll an die leeren Stellen zwischen die Pflanzen Steinplatten, Bretter u. drgl. auf den Boden legen, wo man dann des Morgens Tausende darunter verkrochen finden wird, um sich bis zur Nacht verborgen zu halten.
