- an herbicidally effective amount of ametryn and topramezone prepared for application to soil prior to emergence of crops.
An herbicide composition for use in crop production comprising an active ingredient having
- about 30 percent to about 65 percent ametryn;
- about 0.4 percent to about 1.3 percent topramezone;
- and
- about 25 percent to about 65 percent atrazine.
A method for reducing the growth of weeds in soil during crop production comprising applying a combination of ametryn and topramezone to the soil prior to the emergence of crops.
