The approach to meeting the objectives of this project plan will be in the form of field evaluations and a green house evaluation. Cultivation requirements for weed control as a function of the rate of sugarcane emergence and the crops ability to shade the row will be compared. The hypothesis that planting short-season seeded crops during the fallow season will aid in reducing johnsongrass and bermudagrass infestations and will be economically advantageous over a non-crop fallow system, will be tested. New herbicides will be evaluated for their ability to reduce bermudagrass emergence following winter dormancy. New herbicide chemistries will likely offer increased options for weed control in sugarcane and when available will be evaluated for efficacy. Current forms of resistance to the sugarcane borer are associated with low sugar yields. Related species of sugarcane will be evaluated for forms of resistance that may not be associated with low sugar yields. Silica will be evaluated in the greenhouse and in field plots for its potential of increasing insect resistance. Finally, a series of evaluations will be conducted in commercial sugarcane fields determining if feeding by the sugarcane aphid is sufficient to cause economic yield losses.
