| solarization for nematode disinfestation of small volumes of soil. | several polyethylene plastics were evaluated as potential materials for disinfesting small volumes of soil containing nematodes. bursaphelenchus seani, cultured on the fungus monilinia fructicola in petri dishes, was used to bioassay the survival and reproductive capability of nematodes buried 7.5 cm deep in margate fine sand (soil moisture = 4.9%). the soil was exposed to sunlight for 6 days in may 1987. the highest mean temperatures recorded at 7.5 cm deep were 38 +/- 1 c, 43 +/- 1 c, 43 +/- 1 ... | 1988 | 19290301 |
