Long-Term Efficacy of Four Grain Protectants on Stored Sorghum

A 28-week study evaluating the residual efficacy of four grain protectants (Gravista®, Diacon® IGR, Sensat™, EverGreen®) against two stored grain pests, Rhyzopertha dominica and Sitophilus oryzae. Data includes initial adult mortality, progeny counts, and assessments of frass and insect-damaged kernels. The dataset was published by the Department of Agriculture and last updated in March 2026.

Use Cases

• Compare the long-term residual efficacy of different active ingredients based on mortality and progeny data.
• Model pest population dynamics in treated grain based on progeny production counts.
• Assess the relationship between insecticide application and grain quality based on frass and kernel damage metrics.

Strengths

• Data covers a 28-week storage period with measurements taken every 4 weeks.
• Includes results for two major stored product pest species, Rhyzopertha dominica and Sitophilus oryzae.
• Measures multiple efficacy endpoints: adult mortality, progeny production, frass, and kernel damage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
