Abstract
Summary Molasses was applied to soil through sprinkler irrigation system or by overhead boom sprayer. In a papaya plantation on Maui where high and damaging populations of reniform nematodes had caused a reduction in fruit yield and quality, the molasses applications lowered nematode soil populations and resulted in marked improvement in the tree growth and harvestable fruit. When applied to Chinese cabbage, there was a decrease in the numbers of Heterodera nematode cysts following harvest. Preplant applications of molasses to onions improved plant color and onion yield although no difference in soil nematode populations or in cyst number was observed. Molasses soil amendments supply carbohydrates and alter the C/N ratio. This affects the soil microbial ecology, usually resulting in lowered populations of plant parasitic nematodes as well as having other favorable effects on plant growth. The specific mechanisms involved are not well understood and vary with the crop, soil conditions, and nematode species present.
