Other Contributions: Notes on Two Experiments with Nematode Control in Sugarcane

Abstract

When DBCP, D-D and 2 formulations of EDB were applied at 34 liters, 303 liters and 101 kg active ingredient (ai) per ha respectively over the entire area, and at higher rates of 45 liters, 404 liters and 136 kg ai respectively, sugarcane yields were increased by fairly similar amounts in all instances. Injecting EDB into the soil at a depth of 38 cm appeared to give no advantage over injecting it at a depth of 23 cm. The reasons for the relatively poor responses obtained, including those due to treatment with aldicarb and filtercake (an organic by-product of sugar manufacture) are discussed.
