Pod sucking bugs
Green stink bugs or slender brown bugs suck the young pods, leaving dark spots, shriveled seeds and pods that drop early.

Where the damage shows
When to act
From pod set, shake the plants over a cloth along 1 meter of row at 5 spots, early in the morning. Act when you count about 2 bugs (adults and big nymphs) per meter of row during pod filling.
What to spray
Active ingredients only, never brands. The IRAC group tells how it works: switch to a different group next time, so the pest does not learn to survive it. Spray only when the damage is worth the cost, and only with products registered with the Fertilizer and Pesticide Authority for your crop. Follow the label. The Shopee and Lazada links only show who sells something with that active ingredient, not a recommendation of any seller or product.
How to prevent it
- Plant on the same dates as your neighbors. Late fields draw the bugs from early ones.
- Sow a small strip of the same crop a little earlier as a trap. Handpick or spray only that strip.
- Crush egg rafts and the clusters of young nymphs under the leaves.
- Remove legume weeds and volunteer plants around the field.
- Harvest pods on time. Dry pods left in the field feed the next generation.
Natural enemies and biological help
- Egg wasps such as Trissolcus and Telenomus, tachinid flies, spiders and ants attack the eggs and nymphs. Fewer broad sprays leave more of them.
