Brown lawn is usually one of four things: drought stress, lawn grubs chewing the roots or leaves, fungal disease after warm humidity, or a fertiliser burn. Lift a corner of turf. If it rolls back like carpet and you find C-shaped curl grubs, treat for insects. If the soil is bone dry below 50 mm, water deeply. If the thatch smells sour and the blades have spots, look at fungus.
Only if the label says it is safe for buffalo. Many dicamba products burn Stenotaphrum (buffalo). Choose a bindii and clover killer based on bromoxynil or a buffalo-specific formulation, and never guess from a generic hose-on bottle.
