Application

Mode of Action:

• Pendimethalin is a inhibitor of microtubule assembly.

• Pendimethalin is a selective herbicide, absorbed by the roots and leaves.

• Affected plants die shortly after germination or following emergence from the soil.

Usage of Pendimethalin:

• Pendimethalin can control most annual grasses and many annual broad-leaved weeds, in cereals, onions, leeks, garlic, fennel, maize, sorghum, rice, soya beans, peanuts, brassicas, carrots, celery, black salsify, peas, field beans, lupins, evening primrose, tulips, potatoes, cotton, hops, pome fruit, stone fruit, berry fruit (including strawberries), citrus fruit, lettuce, aubergines, capsicums, established turf, and in transplanted tomatoes, sunflowers and tobacco.

• Applied pre-plant incorporated, pre-emergence, pre-transplanting, or early post-emergence.

• Pendimethalin can be also used for control suckers in tobacco.

Phytotoxicity of Pendimethalin:

• Injury to maize may occur if used as a pre-plant, soil-incorporated treatment.

Compatibility of Pendimethalin:

• Not compatible with oxidising or reducing agents or with strong alkali.
