Flow­ers save rice crops

Weekend Argus (Saturday Edition) - - NEWS -

HANOI: Viet­namese rice farm­ers have been us­ing fra­grant flow­ers to save their crops from pests.

Mekong Delta farm­ers have been grow­ing banks of nec­tar- rich flow­ers along their paddy fields to at­tract wasps that prey on the brown plant- hopper, which de­stroys thou­sands of hectares of paddy.

The wasps feed on the flow­ers’ nec­tar, but de­posit their eggs in the adult plant­hop­pers, which are de­stroyed when the lar­vae hatch.
