Beneficial bacteria for improving white clover establishment
AbstractWhite clover (Trifolium repens) seedlings encounter the adverse impacts of root parasitic nematodes during plant establishment Of these root knot (Meloidogyne trifoliophila) and cyst (Heterodera trifolii) nematodes are well established in the North Island while only the latter is encountered in South Island pastures Once root damage is caused by the nematode the resulting wound can facilitate the entry of root pathogenic fungi into the plant compounding the problem Use of naturally occurring micro organisms to counteract the adverse impacts of nematodes in white clover is an attractive option Bacteria isolated from New Zealand pastures were screened for their beneficial effects on white clover seedling vigour in pot experiments and a field experiment When applied as a drench at sowing several bacterial strains (mostly Bacillus and Pseudomonas) produced significant (P<005) increases in seedling dry weights in pot experiments (up to 30) with some also showing significant reductions (25) in root cyst nematode populations Data from the field experiment suggests that some of these bacteria when used as a biopolymer seed coating can enhance seedling vigour by around 25 which shows promise for future field use of these strains
