Crops it troubles
How to tell it is a grass
Round, hollow stems with joints, and leaves in two rows. The group decides what kills it, so check the stem and the leaf before you buy a herbicide.
How to keep it out
Plow and harrow two or three times in the dry season to bring the runners up to dry, then shade it out with a crop, a legume cover crop or trees; it does not stand shade.
Active ingredients whose labels name it
- GlyphosateHRAC 9
- Glufosinate ammoniumHRAC 10
Herbicides registered in the Philippines with these active ingredients name this weed on their labels, each for the crops its label lists, such as banana, cacao, calamansi and citrus. Use one only where the label names your crop, and follow it.
How to control it
What to do and which active ingredients work depend on your crop and how old it is. The weed control helper in anee.io gives both, for coconut and every other crop it grows in.
