Effect of dazomet on annual bluegrass emergence and creeping bentgrass establishment in turf...

Dazomet (tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione) is a soil fumigant labeled for turfgrass renovation. Little is known about dazomet efficacy on annual bluegrass (Poa annua L.) seedling emergence, particularly when it is surface-applied. The objectives of this field study were to determine (i) the effects of rate and plastic covering of surface-applied dazomet on annual bluegrass seedling emergence in turf; and (ii) effective creeping bentgrass seeding intervals following surface applications of dazomet. All treatments were applied to established turf during late summer in 2
