Chemical Weed Control
Growers are beginning to use Round-Up® herbicide to replace clean cultivation in east, south and central Texas. It is applied at a rate of 1-quart per 50 gallons of water to one acre in April, June and August.
Round-Up® has been recently implicated in nickel deficiencies being found in some pecan orchards and producers should be aware of scientific studies underway and alert for symptoms turning up in their own trees.
A sod tractor path is often maintained down the tree row to facilitate equipment entry into the orchard during rainy weather.
