Chateau (flumioxazin)
Chateau (flumioxazin) is a contact and residual herbicide that controls both grasses and broadleaf weeds in nonbearing orchards. Hence, it is only useful in young orchards or those that have lost a crop. It can be used in the year of planting if the trees are shielded from contact with the spray. It is labeled for apples and all stone fruits. As a contact material it is most effective when applied while the emerged weeds are very small. Application rate is 6 to 12 ounces per treated acre. The REI is 12 hours and the PHI is 365 days.
