Mineral dusts protect stored pulses from beetle damage without chemicals

OpenAlex · 2026-07-10

Researchers tested three inert dusts as alternatives to chemical pesticides for protecting stored green gram and chickpea from pulse beetles. Some dusts proved effective and long-lasting, offering a safer, residue-free option for grain storage.

1

Three inert dusts were compared for their ability to kill and repel Callosobruchus chinensis beetles on two pulse crops: green gram and chickpea.

2

The dusts differed in both efficacy (kill rate) and persistence (how long protection lasted), indicating material choice significantly affects storage outcomes.

Inert dusts present a chemical-free, residue-safe alternative to conventional insecticides for small-scale or organic pulse storage.
