The 'push-pull' method is a farming technique in which farmers plant Napier grass and Desmodium legumes interspersed along with their primary crop.
Desmodium is a natural insect repellent that 'pushes' away would-be pests. Meanwhile, Napier grass attracts, or 'pulls', pests to lay their eggs on the grass's sticky leaves. The plant then produces a glue-like substance that traps and kills the larvae.
In addition, desmodium roots produce natural chemicals that suppress the growth of certain harmful weeds. Also, as a legume, desmodium naturally enriches farm land by fixing nitrogen in the soil.
As many of us begin planting our own vegabable gardens, we should take the lead from Agnes for sustainable, organic pest control methods!
