Common uses	Reasons	Main agricultural crops
Pre-planting weed control	Low cost; labor-saving vs. manual only; glyphosate weed resistance	Maize; soybean; rice
Post-emergent weed control	Low cost; labor-saving vs. manual only	Banana; coffee; oil palm; orchard crops; tea
Pre-harvest defoliant	Improve harvest efficiency; reduce crop damage during harvest process	Cotton; potato
Pre-harvest desiccant	Improve harvest efficiency; shorten harvest to replanting interval	Soybean
Post-harvest desiccant	To remove breeding habitat for stable fly; shorten harvest to planting interval	Pineapple; soybean
