Each female plant is capable of producing over 24,000 seeds, which may remain viable for up to 3 years. Herbicides are usually not needed, but in case you use them, choose these effective against dicots, and apply them just before flowers seem. Competition – White cockle is a “sun-lover” and therefore, most crops seeded at high rates and vigorous forage stands compete well with white cockle seedlings. Useful postemergent herbicides approved for strawberries in the planting year include Stinger (labelled in NY and several other states; check your state), and the grass killers Poast and Select Max. identification difficult; consistent control with ALS herbicides and glyphosate may be difficult in soybean. In all four cases the weed control was executed using the same herbicide in the same doses and with regard to the weed species it showed the same level of efficiency. Management: Early postemergence herbicide applications improve control. White Cockle is known to grow in pastures and on the outskirts of fields.
