Abstract:
When ready, harvest by whole plant removal. Avoid harvesting when it is very wet as this may lead to disease spread especially when piece meal harvesting is done at physiological maturity. Harvest your beans, dry them well and thresh. After threshing, winnow to remove trash and dry properly. Store well dried beans in clean containers and treat with actelic (1 sachet to 90 kg of seed), ash (0.25 - 0.5 ash: 1 bean by volume) to prevent bruchid damage. Plant extracts (tobacco leaf powder, Mexican marigold and tephrosia), regular sunning (once a week for 6 hours) and sieving can also reduce bruchid damage.
