BIOFUMIGATION

BREEDING TARGETS - BASICS• FAST COVERING OF THE SOIL

suppression of weeds saving soil humidity by elimination unproductive evaporation

• HEALTHY PLANT DEVELOPMENT security for different crop rotations fast and deep root system good uptake of free nutrients

BREEDING TARGETS – GROWING CONDITIONS

- Seed density- Sowing time- Sowing technique- Straw management- Fertilizer- Water

- Organic matter production

- Winter hardiness

BREEDING TARGETS – CONTROLLING DISEASES

Beet cyst nematode Heterodera schachtii

• FIRST RESISTANT VARIETY IN 1980 FROM P. H. PETERSEN

• FIRST VARIETY WITH MORE THAN 90% NEMATODE REDUCTION

BREEDING TARGETS – CONTROLLING DISEASES

• stubby root nematodes (Trichodorus sp.)• Transmitter of Tabacco rattle Virus (corky ring spot syndrome)

FODDER RADISH VARIETIES:SILETTA NOVA, BENTO, LUNETTA

WITH BCN RESISTANCE: COLONEL

BREEDING TARGETS – CONTROLLING DISEASES

Root knot nematodes Meloidogyne chitwoodi, M. fallax, M. hapla, M. incognita; M. javanica)

MULTI-RESISTANT VARIETIES:DEFENDER: M.c. and M.f.COMMODORE: M.h.BOSS: M.i. and M.j.CONTRA: M.c., M.f., M.i. M.j. and M.h.

BREEDING TARGETS – CONTROLLING DISEASES

• Ditylenchus dipsaci - Stem nematode

• Pratylenchus – free living nematodes

• Rhizoctonia solani• Verticillium• …..

NEW TECHNIQUES: BIOFUMIGATION

LAST BUT NOT LEAST: SEED QUALITY

Highest quality seed, well above the minumum standard

CONCLUSION

ALL PARTS HAVE TO BE OPTIMIZED

AND LEAD TOGETHER TO

SUCCESS

FOR THE ENVIRONMENT

AND THE FARMER.
