Over the past two decades, feathertop rhodes grass has gone from being a minor cropping weed to a major problem for northern - and now some southern - growers... The only way to control fTr effectively is to use an integrated weed management (iWM) approach... The efficacy of herbicides against fTr drops rapidly when plants are larger than the early tillering stage or are moisture stressed, so spray as soon as possible after rain for best results...
