Cotton Jassid Insecticide Efficacy in Tanzania, 2024–2025

Four synthetic insecticides were evaluated for controlling cotton jassids (Amrasca biguttula) in field experiments across three locations in Tanzania during the 2024–2025 growing season. Imidacloprid was the most effective, achieving mean population reductions of 67.59% for nymphs and 66.31% for adults. The dataset, authored by Joseph Elias Nyesse and published on figshare, contains results from a randomized complete block design experiment.

Use Cases

• Compare the relative efficacy of Lambda-cyhalothrin, Chlorpyrifos, Imidacloprid, and Profenofos based on mortality assessments at 24, 48, and 72 hours.
• Analyze insecticide performance variation across different locations (WCGA and ECGA) in Tanzania mentioned in the description.
• Model population reduction trends over time using Abbott's formula calculations described in the methods.
• Inform integrated pest management (IPM) program design based on the superior performance of Imidacloprid highlighted in the results.

Strengths

• Experimental data from a replicated field trial using a randomized complete block design (RCBD).
• Results include specific efficacy percentages, such as 67.59% nymph reduction for Imidacloprid.
• Clear temporal coverage for the 2024–2025 growing season and spatial coverage across three locations in Tanzania.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (178.2 KB), indicating limited scope.
