Serve-ag is Tasmania’s leading company in biofumigation and soil health management. With more than a decade of experience developing and integrating biofumigation into Tasmania’s high value cropping systems, we have established relationships with companies and researchers world wide, providing you with superior seed varieties to suit your needs.
Biofumigation refers to the process of growing specific brassica cultivars that have been bred for high levels of certain compounds (glucosinolates), which upon maceration, release natural chemicals called Isothiocyanates (ITC’s). These ITC’s are similar to the chemical fumigant metham sodium, and when managed correctly, can help to naturally suppress pests and soilborne diseases. Your local Serve-Ag agronomist has the agronomic experience to assist you get the most from your biofumigant crop.

Serve-Ag stock a premium range of biofumigant seed varieties, bred by leading researchers throughout Europe. The varieties we stock are chosen for their enhanced glucosinolate production and agronomic traits that suit our cropping systems in Tasmania.
Caliente 199 (Brassica juncea)
This mustard variety was bred by researchers in Italy for disease suppression and is produced in the United States by High Performance Seeds. Caliente 199 is a superior biofumigant, renowned for its high glucosinolate production levels (sinigrin) compared to any other commercial variety, giving this variety maximum ability to naturally biofumigate soils and suppress soilborne diseases. Caliente 199 is sold exclusively by Serve-Ag throughout Tasmania.
Sowing Rate: 12kg/ha
Nemat (Eruca sativa)
Nemat, an arugula variety, was developed by researchers in Italy for nematode control and is again produced in the United States by High Performance Seeds. Nemat produces root exudates that both attract pest nematodes into the root zone and help suppress reproduction. These root exudates contain a different range of glucosinolates (glucoerucin) compared to mustards, providing enhanced nematode control. Nemat can be grown as a stand-alone crop for maximum nematode control, or in mix with Caliente 199 for maximum disease and nematode control. Nemat is sold exclusively by Serve-Ag throughout Tasmania.
Sowing Rate: 8kg/ha
Doublet/Terranova (Raphanus sativus)
Doublet oil seed radish, a biofumigant variety bred by researchers in the Netherlands, contains a different range of glucosinolates (glucoraphanin) which reduce a broad range of nematodes. Doublet, or the new variety Terranova, is frost resistant up to -8OC and provides resistance to club root, making this variety ideal for use in rotations including brassicas.
Sowing Rate: 20-25kg/ha
Utopia (Brassica carinata)
Utopia, also known as Abyssinian mustard, is a new variety of mustard with biofumigation potential and very good frost tolerance. Brassica carinata is an annual, with high biomass production and very late flowering. Utopia establishes well with rapid growth up to 1 m in height. Utopia is suitable for most soils, and prefers well drained but moist soils. Utopia is known for good rooting depths, along with good yields and effective organic matter. Utopia has moderate ability to supress soilborne diseases, but provides little nematode control.
Sowing Rate: 15kg/ha
