摘要

guinea grass (Panicum maximum) is a clump-forming perennial that may grow to 3 m tall. It is widespread in most cane growing districts. Guinea grass seedlings are controlled by a range of knockdown and pre-emergent herbicides; guinea grass clumps aredifficult to control in-crop.Para grass (Brachiaria mutica) is a perennial creeping grass that will root at each node. It is widespread in cane growing regions, particularly in the wetter regions and wetter areas of farms. Both grasses are introduced pasture species.These grasses are responsible for crop production losses through competition with the cane crop, higher production costs due to expensive control measures, and shortened ratoon cropping cycles.A spot spraying trial was set out in a ratoon cane crop Q200 A range of herbicides and herbicide mixtures was applied to well established guinea grass stools (up to 50 cm tall) and para grass patches that had runners up to 40 cm long. The cane was stooling and up to 60 cm tall at the time of application. Activator~R @ 250 mL per 100 L was the adjuvant used.DalaPon 740 (2,2 DPA) plus Daconate~R, Balance~R 750 WG plus Daconate~R, Soccer~R 700 WG plus Balance~R 750 WG plus Daconate~R as well as Krismat~R WG plus Daconate~R treatments all gave excellent control of both guinea grass and para grass.While Balance~R 750 WG alone and the Flame~R mixture both controlled para grass and had reasonable control of guinea grass the herbicide damage to the cane crop was unacceptable.Guinea grass clumps and established para grass patches can be managed in ratoon cane with a range of mixtures using the spot spraying method without the addition of diuron to the spray mixture.
