General Information


Harvester is a nonvolatile herbicidal chemical for use as a general herbicide to control weeds in commercial greenhouses and nurseries; ornamental seed crops (flowers, bulbs, etc. except in the state of California); landscape, industrial, recreational, commercial, residential, and public areas; turf renovation (all turf areas except commercial sod farms); dormant established turfgrass (bermudagrass, zoysiagrass –nonfood or feed crop); and aquatic areas. Absorption and herbicidal action is usually quite rapid with effects visible in a few days. Harvester controls weeds by interfering with photosynthesis within green plant tissue. Weed plants should be succulent and actively growing for best results. Rinse all spray equipment thoroughly with water after use. Avoid spray drift to crops, ornamentals, and other desirable plants during application, as injury may result. Application to muddy water may result in reduced control. Minimize creating muddy water during application.

Use of dirty or muddy water for Harvester dilution may result in reduced herbicidal activity.

Avoid applying under conditions of high wind, water flow, or wave action.

Refer on the label for the table \"Water Use Restrictions Following Applications With Harvester Herbicide (days)\".

Limitations, Restrictions, and Exceptions


Harvester provides fast control of broadleaf and grassy weeds in industrial, recreational, golf course, commercial, residential, and public areas. Harvester is a nonselective herbicide that rapidly kills undesirable above ground weed growth in 24-36 hours. Avoid application of Harvester to desirable plants. Harvester is a contact/desiccant herbicide; it is essential to obtain complete coverage of the target weeds to get good control. Improper application technique and/or application to stressed weeds may result in unacceptable weed control. For best results, apply to actively growing, young weeds. Difficult weeds (such as perennial or deeply-rooted weeds) can often be controlled by tank mixing Harvester with other systemic-type herbicides. Refer to other product labels for specific application directions.

For residual weed control, tank mix Harvester with a preemergent herbicide labeled for intended use site. When mixing Harvester with another herbicide, it is recommended to mix just a small amount first to determine if the mixture is physically compatible before proceeding with larger volumes.

Applied Biochemists has not tested all possible tank mixtures with other herbicides for compatibility, efficacy or other adverse effects. Before mixing with other herbicides, Applied Biochemists recommends, you first consult your state experimental station, state university or extension agent.

Grounds maintenance weed control: Harvester can be used as a spot or broadcast spray to control weeds in public, commercial and residential landscapes, including landscape beds, lawns, golf courses and roadsides. Harvester can also be used for weed control around the edges and nonflooded portions of ponds, lakes and ditches. Trim and Edge weed control: Harvester can be used to eliminate undesired grass and broadleaf plant growth in a narrow band along driveways, walkways, patios, cart paths, fence lines, and around trees, ornamental gardens, buildings, other structures, and beneath noncommercial greenhouse benches. Vegetation control with Harvester is limited to the spray application width. Do not exceed the labeled rate of Harvester as excessive rates may result in staining of concrete-based materials. Harvester, since it does not translocate systemically, can be used as an edging or pruning tool when precisely applied to select areas of grass or to undesirable growth on desirable ornamental bedding plants, ground covers, etc. Industrial weed control: Harvester can be used as a spot or broadcast spray either alone or in combination with other herbicides as a fast burndown or control weeds in rights-of-ways, railroad beds/yards, highways, road, dividers and medians, parking lots, pipelines, pumping stations, public utility lines, transformer stations and substations, electric utilities, storage yards, and other non-crop areas.

Broadcast: 1-2 pts. Harvester per acre in sufficient water to insure good spray coverage. Add the labeled rate of 75% or greater nonionic surfactant per 100 gals. spray mixture. Greater water volumes are necessary if the target plants are tall and/or dense. It is recommended that 60 gals. or greater water volume be used to obtain good coverage of dense weeds.
