Ageratum, tropic	Ageratum conycoides
Balsamapple	Momordica charantia
Castorbean	Ricinus communis
Crabgrass	Digitaria spp
Crotalaria	Crotolaria spp
Dallisgrass	Paspalum dilatatum

Moana loa vine*	Canavalia cathartica
Morningglory	Ipomoea spp
Oxalis	Oxalis spp
Popolo	Solanum sandwicense
Richardsonium	Richardsonia spp

*Suppression – a visible reduction in plant population and/or plant vigor as compared to an untreated area and generally not accepted as control.

USE PRECAUTIONS - PINEAPPLE

•Do not exceed 4.8 lb VELPAR® DF per acre per crop.

•Do not apply VELPAR® DF within 181 days of harvest.

SUGARCANE

VELPAR® DF is recommended for selective weed control in sugarcane except in the State of Florida.

APPLICATION INFORMATION

Apply a single treatment of VELPAR® DF per year using a fixed-boom sprayer and a minimum of 25 gallons per acre unless otherwise directed.

HAWAII

Apply VELPAR® DF pre- or postemergence at the following rates for the indicated soil texture:

	DuPont™
VELPAR® DF (Lb/Acre)
	(Plus surfactant
Soils	0.25% by volume)
Coarse Texture
Sand, loamy sand, sandy loam	2/3 - 1 2/10
Medium Texture
Loam, silt loam, silty clay loam	2/3 - 2 1/3
Fine Texture
Clay, gray hydromorphic clay	2 1/3 - 4 8/10

Use the higher levels of the recommended dosage ranges on soils high in organic matter. Do not apply more than twice the highest recommended rate for the indicated soil texture per crop (18–24 months).

A surfactant is recommended for all uses.

For preemergence use only, VELPAR® DF may be applied with aerial equipment using at least 10 gallons of spray per acre.

For spot treatments of emerged weeds, VELPAR® DF may be applied with a knapsack sprayer in concentrations of

0.6- 4.8 pounds per 100 gallons of water. Apply a sufficient volume to thoroughly wet weed foliage, but do not exceed 40 gallons of spray per treated acre. Use the lower concentrations on coarse-textured soils that are low in organic matter, and use the higher concentrations on fine-textured soils that are high in organic matter.

LOUISIANA

Apply 2/3 - 1 2/10 pound of VELPAR® DF per acre broadcast in the fall before sugarcane emerges or in the spring before active cane tillering begins. Fall treatments of 2/3 - 1 2/10 pound per acre may be followed by a spring treatment of 2/3 - 1 2/10 pound per acre. Do not apply more than 2 pound per year. Use the lower rates on coarse textured soils and the higher rates on fine textured soils.

PUERTO RICO

For preemergence treatments, apply 1/3 - 2/3 pound of VELPAR® DF per acre.

For postemergence treatments, apply 1/3 - 2/3 pound of VELPAR® DF per acre to weeds after they have emerged. Use the lower rates on coarse-textured soils and the higher rates on fine-textured soils (high in clay or organic matter). Each ratoon may receive up to 2/3 pound of VELPAR® DF per acre.

For spot treatment of emerged weeds, VELPAR® DF may be applied with a knapsack sprayer in concentrations of 1/3 - 2/3 pound per 100 gallons of water. Apply a sufficient volume to wet the weed foliage. Do not exceed 100 gallons of spray per treated acre. Use the lower concentration on coarse-textured soils and the higher concentration on fine-textured soils.

Note: Since it is difficult to calibrate “spot” knapsack applications, extra care must be taken not to exceed the rate equivalent of the maximum of 2/3 pound VELPAR® DF per acre.

Do not apply more than 1 1/3 pound of VELPAR® DF per acre per crop season.

TEXAS

Apply 2/3 - 2 1/3 pound of VELPAR® DF per acre. On plant cane, apply the herbicide before the cane emerges or as a directed layby treatment. On stubble cane, apply VELPAR® DF preemergence (up to the 3-leaf stage) or as a directed layby treatment. A pre- or early postemergence treatment may be followed by a layby treatment, provided at least 60 days have elapsed and 3 inches of rainfall or sprinkler irrigation have occurred since the first treatment.

Do not apply more than 2 1/3 pound of VELPAR® DF per acre per season.
