Sumistatus 240 EC (Sumitomo Chemical Agro Australia): A Selective Pre-Emergent Herbicide

Active Ingredient: Pendimethalin (240 g/L), belonging to the dinitroaniline class of herbicides.

Mode of Action: Sumistatus 240 EC acts as a pre-emergent herbicide, preventing the germination and growth of susceptible weeds by disrupting cell division at the root tip. It forms a barrier in the soil, inhibiting weed seed germination and early seedling development.

Target Weeds:

• Annual grasses: Crabgrass, summer grass, ryegrass, windmill grass, barnyard grass, and others.

• Broadleaf weeds: Chickweed, purslane, amaranthus, fathsheed, tribulus, and some others.

Benefits:

• Long-lasting control: Provides up to 3 months of pre-emergent weed control depending on soil type and rainfall.

• Selective control: Primarily targets germinating weeds, minimizing harm to established plants when applied correctly.

• Flexible application: Can be applied pre-plant, pre-emergence, or post-emergence (before weeds exceed the 4-leaf stage).

• Suitable for various settings: Labeled for use in lawns, gardens, ornamentals, and some agricultural settings.

• Low leaching potential: Minimizes the risk of contaminating groundwater.

Drawbacks:

• No control over established weeds: Only effective against germinating seeds and young seedlings.

• Residual activity: Can affect desirable seedlings planted too soon after application.

• May not control all weed species: Check the label for specific target weeds.

• Requires accurate application: Uneven application can lead to patchy weed control.

Important Considerations:

• Always read and follow the label instructions carefully before using Sumistatus 240 EC.

• Apply only to listed target weeds and at recommended rates and timings.

• Calibrate spraying equipment for accurate application.

• Do not apply to waterlogged or frozen soil.

• Be aware of potential allelopathic effects on certain crops following application.

Alternatives:

• Post-emergent herbicides: Control emerged weeds but may require multiple applications and can harm desirable plants if not applied carefully.

• Mulching: Suppresses weed growth naturally but needs regular maintenance.

• Hand weeding: Effective for small areas but can be labor-intensive.
